AI Technical Summary
In the display of electronic devices, as the form factor shrinks and the functionality increases, it becomes increasingly difficult to provide sufficiently high capacitance to the subpixels of each pixel, especially due to the limitations of critical size.
A multilayer dielectric and conductive layer structure is adopted, including a first conductive layer, a first dielectric layer, a second conductive layer, a second dielectric layer, and a third conductive layer. The combination of these layers forms a capacitor connection structure and an interconnect structure, thereby increasing the total capacitance.
Within a limited space, higher electrical capacity was achieved, supporting higher resolution displays and reducing the power requirements for electrical signals.

Abstract
Description
Technical Field
[0001] This disclosure relates to a semiconductor device, and more particularly to a trench capacitor structure. Background Technology
[0002] Pixels are used to display images on the screen of an electronic device. For example, in the Organic Light-Emitting Diode (OLED) layer of an electronic device, there are multiple pixels within the OLED layer. Each corresponding pixel in the multiple pixels includes multiple sub-pixels. The multiple sub-pixels typically include three sub-pixels: a red (R) sub-pixel, a green (G) sub-pixel, and a blue (B) sub-pixel. In other words, each corresponding pixel in the multiple pixels includes three sub-pixels, making each corresponding pixel in the multiple pixels a RGB pixel. As electronic devices become smaller (e.g., smaller in overall size and thinner in overall thickness) and the number of complex functions performed simultaneously continues to improve or increase, it becomes increasingly difficult to provide sufficiently high capacitance for the sub-pixels of each corresponding pixel in the multiple pixels.

[0117] Figure 1A A simplified diagram of at least two pixels 100 in a larger pixel array (not shown). Each pixel 100 includes multiple sub-pixels 102a, 102b, and 102c. In other words, each of these pixels 100 has three sub-pixels 102a, 102b, and 102c.

Figure 1A The cross-sectional view of one or more capacitor structures cut by line 1B-1B of the leftmost sub-pixel shown. Although the following discussion will focus on Figure 1A The leftmost sub-pixel 102a is shown, but it is easy to understand that the following discussion will readily apply to it. Figure 1A The other sub-pixels 102a, 102b, and 102c of pixel 100 shown.
[0119] Sub-pixel 102a includes transistor layer 104, transistor layer 104 is Figure 1B The bottommost layer shown.

[0121] One or more first interconnect structures 110 are located within the first dielectric layer 108. One or more first interconnect structures 110 extend into and through the first dielectric layer 108 to reach the first surface 106. One or more first interconnect structures 110 are coupled to one or more transistors within the transistor layer 104. One or more first interconnect structures 110 are exposed and accessible at the second surface 111 of the first dielectric layer 108.
[0122] The second dielectric layer 112 is stacked on the second surface 111 of the first dielectric layer 108. The second dielectric layer 112 is in direct contact with the second surface 111 of the first dielectric layer 108. The second dielectric layer 112 includes a third surface 113. The second dielectric layer 112 is made of at least one of the following materials: undoped silicate glass (USG), silicon nitride (SiN), fluorinated silicate glass (FSG), low-K (LK) dielectric material, carbon-doped oxygen-rich silicon oxide (ELK) material, black diamond (BD) material, or some other suitable or similar dielectric or non-conductive layer.
[0123] One or more capacitor structures 114a, 114b, 114c are located within the second dielectric layer 112. The one or more capacitor structures 114a, 114b, 114c extend through the second dielectric layer to one or more first interconnect structures 110, such that each of the one or more capacitor structures 114a, 114b, 114c is coupled to a corresponding first interconnect structure of the one or more first interconnect structures 110. The one or more capacitor structures 114a, 114b, 114c include a first capacitor structure 114a, a second capacitor structure 114b, and a third capacitor structure 114c. The first capacitor structure 114a and the second capacitor structure 114b define a first capacitor 116, and the second capacitor structure 114b and the third capacitor structure 114c define a second capacitor 117. The first capacitor structure 114a, the second capacitor structure 114b, and the third capacitor structure 114c are exposed and accessible from the third surface 113 of the second dielectric layer 112. The first capacitor structure 114a includes one or more first sidewalls 116a, the second capacitor structure 114b includes one or more second sidewalls 116b, and the third capacitor structure 114c includes one or more third sidewalls 116c.
[0124] A third dielectric layer 118 is stacked on the third surface 113 of the second dielectric layer 112.

The one or more second interconnect structures 120 are coupled to one or more capacitor structures 114a, 114b, 114c within a second dielectric layer 112. In other words, each of the one or more second interconnect structures 120 is coupled to a corresponding capacitor structure of one or more capacitor structures 114a, 114b, 114c. The one or more second interconnect structures 120 are exposed and accessible from a fourth surface 119 of the third dielectric layer 118.
[0126] The light-emitting device layer 122 may be an organic light-emitting diode (OLED) layer, stacked on the fourth surface 119 of the third dielectric layer 118. The light-emitting device layer 122 includes one or more light-emitting devices (i.e., one or more pixels 100) arranged in an array. The one or more pixels 100 within the light-emitting device layer 122 are used to output images on the display of an electronic device (e.g., a smartphone, smart tablet, display, laptop monitor, or some other similar or analog electronic device with a display). Sub-pixels 102a, 102b, 102c and pixel 100 are coupled to one or more second interconnect structures 120. The OLED (not shown) is present within the light-emitting device layer 122. The OLED (not shown) may be located within the dielectric material of the light-emitting device layer 122. The dielectric material of the light-emitting device layer 122 may be at least one of the following materials: undoped silicate glass (USG), silicon nitride (SiN), fluorosilicate glass (FSG), low K (LK) dielectric material, carbon-doped oxygen-rich silicon oxide (ELK), black diamond (BD) material, or some other suitable or similar dielectric or non-conductive layer.
[0127] To improve the resolution or stability of the display current and output more accurate and detailed images, the dimensions of one or more first sidewalls 116a, second sidewalls 116b, and third sidewalls 116c must be increased (e.g., by increasing height and width) to increase the size of the first capacitor 116 and the second capacitor 117, respectively. However, due to the critical dimension (CD), the dimensions of one or more first sidewalls 116a, second sidewalls 116b, and third sidewalls 116c are limited in size, defined by the amount of available space within the electronic device. In other words, when the electronic device is small or thin, the size of one or more first sidewalls 116a, second sidewalls 116b, and third sidewalls 116c can only be made so large because the available space to accommodate such an increase in size is limited. In other words, the first capacitor 116 and the second capacitor 117 are limited by a critical size, which is the size of one or more first sidewalls 116a, second sidewall 116b and third sidewall 116c of the first capacitor structure 114a, the second capacitor structure 114b and the third capacitor structure 114c.
[0128] Figure 2 For sub-pixel 102a ( Figure 1A The leftmost pixel shown is 100. Figure 1A The cross-sectional view of one or more capacitor structures cut by line 1B-1B of the leftmost sub-pixel shown. Although the following discussion will focus on Figure 1A The leftmost sub-pixel 102a is shown, but it is easy to understand that the following discussion will readily apply to it. Figure 1A The other sub-pixels of pixel 100 shown are 102a, 102b, and 120c. Figure 2 The features shown are Figure 1A The features shown are the same or similar. For the sake of simplicity and brevity in this disclosure, Figure 2 Compared to Figure 1A The details of these same or similar features may not be fully reproduced in the following text. Instead, the following about Figure 2 The focus of the discussion will be on relative to Figure 1A Additional or different features.
[0129] Unlike one or more capacitor structures 114a, 114b, 114c, these structures are replaced by one or more capacitor structures 124a, 124b, such as Figure 2 As shown. One or more capacitor structures 124a, 124b include a pair of capacitor structures 124a, 124b, having a first capacitor structure 124a and a second capacitor structure 124b.
[0130] The first capacitor structure 124a includes a first portion 126 located at or near the second surface 111 of the first dielectric layer 108 and a second portion 128 located at or near the third surface 113 of the second dielectric layer 112. An intermediate dielectric layer 130 is located between and sandwiched between the first portion 126 and the second portion 128. When an electrical signal is applied to the first capacitor structure 124a, a first capacitance 132 exists between the first portion 126 and the second portion 128. The intermediate dielectric layer 130 may be a high-K (HK) dielectric material.
[0131] The second capacitor structure 124b includes a first portion 134 located at or near the second surface 111 of the first dielectric layer 108 and a second portion 136 located at or near the third surface 113 of the second dielectric layer 112. An intermediate dielectric layer 138 is located between and sandwiched between the first portion 134 and the second portion 136. When an electrical signal is applied to the second capacitor structure 124b, a second capacitance 140 exists between the first portion 134 and the second portion 136.
[0132] The first capacitor 132 and the second capacitor 140 are controlled or adjusted by applying electrical signals to the first capacitor 124a and the second capacitor 124b. However, to generate high or large capacitance, large electrical signals must be applied to the first capacitor 124a and the second capacitor 124b. Increasing the size of the first capacitor 124a and the second capacitor 124b can reduce some of the power required to generate high or large capacitance, but similar to increasing the size of the first capacitor structure 114a, the second capacitor structure 114b, and the third capacitor structure 114c, the first capacitor 124a and the second capacitor 124b can only be made this large, otherwise they would be limited by critical dimensions. In other words, when the electronic device is small or thin, the first capacitor 116 and the second capacitor 117 can only be made this large due to the available space to accommodate such an increase in size. In other words, the first capacitor 116 and the second capacitor 117 are limited by critical dimensions, which limit the dimensions of one or more first sidewalls 116a, second sidewall 116b and third sidewall 116c of the first capacitor structure 114a, the second capacitor structure 114b and the third capacitor structure 114c.
[0133] As described below, this disclosure aims to provide and manufacture one or more embodiments of one or more capacitor structures for one or more sub-pixels of one or more pixels, in order to prevent or avoid the aforementioned specific embodiments. Figure 1A , Figure 1B , Figure 2The issue under discussion is that, in the semiconductor industry, as display resolutions increase, capacitors with increasingly higher capacitance are required to provide higher resolution displays. Typically, providing capacitors with higher capacitance occupies more space. However, embodiments of one or more capacitor structures for one or more subpixels of one or more pixels allow for a large amount of high capacitance within each subpixel of one or more pixels. Typically, each pixel includes three subpixels (e.g., a red (R) subpixel, a green (G) subpixel, and a blue (B) subpixel), and each subpixel includes one or more capacitor structures for allowing one or more pixels to display images on the display of an electronic system or device (e.g., a smartphone, tablet, monitor, laptop monitor, or other similar or analog displays).
[0134] Figure 3A This is a simplified diagram of at least two pixels 200 in a larger pixel array (not shown). According to some embodiments, each pixel 200 includes a plurality of sub-pixels 202a, 202b, 202c. In other words, each pixel 200 has three sub-pixels 202a, 202b, 202c. Each pixel 200 has a pixel pitch size 203 extending to all sub-pixels 202a, 202b, 202c of the corresponding pixel 200. In this embodiment, the pixel pitch size 203 is equal to 60 micrometers (μm).
[0135] Since each pixel 200 in this embodiment has three sub-pixels 202a, 202b, and 202c, each sub-pixel 202a, 202b, and 202c has a sub-pixel pitch size 205, which is one-third of the pixel pitch size 203. In this embodiment, the sub-pixel pitch size is equal to 20 micrometers (μm).
[0136] In some embodiments, the pixel pitch size 203 is selected from the range of 2 nanometers (nm) to 1000 micrometers (μm), or equal to the upper and lower limits of this range. The subpixel pitch size 205 is selected from the range of 2 nanometers (nm) to 1000 micrometers (μm), or equal to the upper and lower limits of this range.

Although the following discussion will focus on Figure 3A The leftmost sub-pixel 202a is shown, but it is easy to understand that the following discussion will readily apply to it. Figure 3AOther sub-pixels 202a, 202b, and 202c of pixel 200 shown.
[0138] Sub-pixel 202a includes a transistor layer 204, which is... Figure 3B The bottommost layer shown. Although not shown, transistor layer 204 includes one or more transistor structures (not shown) and includes a first surface 206. Transistor layer 204 is a front end of line (FEOL) transistor layer.

[0152] Figure 6A According to some embodiments, such as Figure 3B The image shows an enlarged view of portion 6A-6A. In other words, Figure 6A for Figure 3B An enlarged view of one or more capacitor structures 214 shown. Figure 6A In the embodiment shown, the first capacitor 236 exists between the lower conductive layer 216 and the middle conductive layer 220, spanning the lower non-conductive layer 218, and the second capacitor 238 exists between the upper conductive layer 224 and the middle conductive layer 220, spanning the upper non-conductive layer 222. Figure 6A The total capacitance of the capacitor structure 214 shown is the sum of the first capacitor 236 and the second capacitor 238, because the first and second capacitors are connected in parallel (see [link]). Figure 6C The circuit diagram of capacitor structure 214 shown is shown.
[0153] The lower conductive layer 216 includes one or more first walls 240, the intermediate conductive layer 220 includes one or more second walls 242 and one or more third walls 244, and the upper conductive layer 224 includes one or more fourth walls 246. The one or more second walls 242 are opposite to the one or more third walls 244. A first capacitor 236 exists between the one or more first walls 240 and the one or more second walls 242, and a second capacitor 238 exists between the one or more third walls 244 and the one or more fourth walls 246.
[0154] The lower conductive layer 216 includes a first U-shaped portion 248 defining a first groove, the intermediate conductive layer 220 includes a second U-shaped portion 250 defining a second groove, and the upper conductive layer 224 includes a columnar portion 252, such that the upper conductive layer 224 has a T-shaped profile. The second U-shaped portion 250 is located within the first groove defined by the first U-shaped portion 248. The columnar portion 252 is located within the second groove defined by the second U-shaped portion 250. The first groove defined by the first U-shaped portion 248 is defined by corresponding first walls of one or more first walls 240. The second groove defined by the second U-shaped portion 250 is defined by corresponding third walls of one or more third walls 244.
[0155] The upper conductive layer 224, including the columnar portion 252, further includes a peripheral portion 253 extending outward from the columnar portion 252. The thickness of the peripheral portion 253 is less than that of the columnar portion 252.
[0156] like Figure 6A The second interconnect structure 230 shown is coupled to the exposed region 256 of the intermediate conductive layer 220. The exposed region 256 is exposed from the upper non-conductive layer 222 and the upper conductive layer 224. In other words, the upper non-conductive layer 222 and the upper conductive layer 224 are not present on the exposed region 256 of the intermediate conductive layer 220. Figure 6A The third interconnect structure 232 shown is coupled to the upper conductive layer 224.
[0157] and Figure 1B The one or more capacitor structures 114a, 114b, 114c shown are Figure 2 Unlike the one or more capacitor structures 124a, 124b shown (where the overall and total capacitance of capacitor structures 114a, 114b, 114c, 124a, 124b are limited due to the critical dimension (CD) problem discussed earlier in this paper), one or more capacitor structures 214 have a higher overall and total capacitance than these corresponding one or more capacitor structures 114a, 114b, 114c. Furthermore, in relation to... Figure 1B The one or more capacitor structures 114a, 114b, 114c shown are Figure 2In the same amount of space, one or more capacitor structures 124a, 124b can be provided with a greater number of capacitor structures 214. Due to the first U-shaped portion 248 of the lower conductive layer 216, the second U-shaped portion 250 of the intermediate conductive layer 220, and the columnar portion 252 of the upper conductive layer 224, one or more capacitor structures 214 have a higher overall or total capacitance relative to one or more capacitor structures 114a, 114b, 114c, 124a, 124b in the same or less space. The first U-shaped portion 248, the second U-shaped portion 250, and the columnar portion 252 allow for the maximization of the dimensions of one or more first walls 240, one or more second walls 242, one or more third walls 244, and one or more fourth walls 246, such that the first capacitor 236 and the second capacitor 238 are higher than the first capacitors 116, 132 and the second capacitors 117, 140, respectively.
[0158] The first U-shaped portion 248, the second U-shaped portion 250, and the columnar portion 252 allow one or more capacitor structures 214 to be smaller than one or more capacitor structures 114a, 114b, 114c, 124a, 124b, thereby enabling a greater number of one or more capacitor structures 214 to be provided within the same amount of space as one or more capacitor structures 114a, 114b, 114c, 124a, 124b. For example, since sub-pixel 202a has a sub-pixel pitch size 205 equal to 20 micrometers (μm), and the size 207 of each capacitor structure 214 is equal to 200 nanometers (nm), the total number of capacitor structures 214 that can be provided within sub-pixel 202a is equal to one hundred, which is greater than when using one or more capacitor structures 114a, 114b, 114c, 124a, 124b (e.g., ...). Figure 1B and Figure 2 The total number of capacitors is shown in the figure. Because one or more capacitor structures 214 have higher capacitance and can provide more capacitor structures within each sub-pixel 202a, 202b, 202c of each pixel 200, when using one or more capacitor structures 114a, 114b, 114c, 124a, 124b, the one or more capacitor structures 214 allow the electronic device to have a more stable and better resolution display. In other words, and in summary, one or more capacitor structures 214 provide higher capacitance, while relative to... Figure 1B and Figure 2The one or more capacitor structures 114a, 114b, 114c, 124a, 124b shown can provide a greater number of capacitor structures within the same space. By having higher capacitance and being able to provide a greater number of one or more capacitor structures 214 in sub-pixel 202a relative to one or more capacitor structures 114a, 114b, 114c, 124a, 124b, the one or more capacitor structures 214 can be used in the display to provide greater stability and functionality.
[0159] The first capacitor 236 ranges from 0.005 pF to 100 F. The second capacitor 238 ranges from 0.005 pF to 100 F. The total capacitance of the capacitor structure is equal to the sum of the first capacitor 236 and the second capacitor 238. In some embodiments, the total capacitance ranges from 0.01 pF to 200 F, or equal to the upper and lower limits of this range.
[0160] The first interconnect structure 210, the second interconnect structure 230, and the third interconnect structure 232 may be made of at least one of the following materials: copper, copper alloy, tungsten, tungsten alloy, or other similar or equivalent conductive materials. The lower conductive layer 216, the intermediate conductive layer 220, and the upper conductive layer 224 may be made of at least one of the following materials: copper, copper alloy, tungsten, tungsten alloy, or other similar or equivalent conductive materials. The lower non-conductive layer 218 and the upper non-conductive layer 222 may be made of at least one high-K (HK) dielectric material selected from the following: SiO2, SiN... x HfSiO4, ZrO2, HfO2, TiO2 or other similar or equivalent high K (HK) dielectric materials.

The corresponding upper surface 231 of the upper conductive layer 224 faces away from the first interconnect structure 210. In at least this embodiment, the fifth dimension 227 is in the range of 2.5 nanometers (nm) to 250 micrometers (μm), or equal to the upper and lower limits of this range.
[0167] The sixth dimension 229 is the thickness of the upper conductive layer 224, extending from the upper non-conductive layer 222 to the corresponding upper surface 231 of the upper conductive layer 224.

Flowchart 300 includes multiple steps, including a first step 302, a second step 304, a third step 306, a fourth step 308, a fifth step 310, a sixth step 312, a seventh step 314, an eighth step 316, a ninth step 318, a tenth step 320, an eleventh step 322, and a twelfth step 324.
[0174] Figures 8A to 8L For manufacturing according to some embodiments, such as Figures 3A to 3C The method of one or more capacitor structures 214 of sub-pixel 202a of pixel 200 shown is as follows: Figure 7 The flowchart 300 shown is a cross-sectional view of each step. Details of each step 302, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322, and 324 will be presented in conjunction with... Figures 8A to 8L The details shown will be discussed. As will be easily understood, with Figures 3A to 3C Features that are the same as or similar to those shown will have the same characteristics as Figures 8A to 8L The same or similar component symbols shown. Furthermore, for the sake of simplicity and brevity in this disclosure, detailed descriptions of elements already referred to herein may not be repeated below. Figures 3A to 3C The details of these characteristics are described.
[0175] exist Figure 8A In the first step 302 shown, one or more trenches 326 are formed extending to the third surface 213 of the second dielectric layer 212. The one or more trenches 326 expose corresponding surfaces of one or more first interconnect structures 210. In other words, the one or more first interconnect structures 210 and the one or more trenches 326 generally have a one-to-one correspondence.
[0176] One or more trenches 326 are formed within the second dielectric layer 212 using a technique known in the semiconductor industry. For example, in at least one embodiment, one or more trenches 326 are formed by dry etching of corresponding regions of the second dielectric layer 212. One or more regions of the second dielectric layer 212 are exposed to a photoresist patterning process. For example, after forming a photoresist material around one or more regions along the third surface 213 of the second dielectric layer 212, one or more regions are exposed to a dry etching process in which a chemical etchant is applied to one or more regions of the second dielectric layer 212 to remove corresponding portions of the second dielectric layer 212, thereby forming one or more trenches 326 and exposing corresponding surfaces of one or more first interconnect structures 210 from the second dielectric layer 212. Once the dry etching has occurred and is complete, the photoresist material is removed from the third surface 213 of the second dielectric layer 212, thereby producing a result such as Figure 8A The structure or component shown. For example... Figure 8A As shown, the width 325 of each corresponding trench in one or more trenches 326 is less than the second width 329 of the corresponding surface 327 of each corresponding first interconnect structure in one or more first interconnect structures 210. In at least this embodiment, the width 325 is in the range of 2 nanometers (nm) to 20 micrometers (μm), or equal to the upper and lower limits of this range. In at least this embodiment, the second width 329 is in the range of 2 nanometers (nm) to 20 micrometers (μm), or equal to the upper and lower limits of this range. In other words, the second width 329 is the same as the fourth width 272 discussed above herein.
[0177] In at least one embodiment, the width 325 is equal to the first width 262, such as Figure 6B As shown. In at least one embodiment, the second width 329 is equal to the second width 266, as... Figure 6B As shown.

The first conductive layer 328 corresponds to... Figure 6A The lower conductive layer 216 of the capacitor structure 214 shown. The first conductive layer 328 is formed by deposition techniques known in the semiconductor industry. For example, the first conductive layer 328 is formed using a physical vapor deposition process (PVD), wherein the first conductive layer 328 is formed thinly along the third surface 213, one or more sidewalls 330, and the corresponding surfaces of one or more first interconnect structures 210.
[0179] After forming the first conductive layer 328 in the second step 304, as follows Figure 8C In the third step 306 shown, a first non-conductive layer 332 is formed on the first conductive layer 328. The first non-conductive layer 332 is formed to cover the entire first conductive layer 328. The first non-conductive layer 332 corresponds to... Figure 6A The lower non-conductive layer 218 is shown. The first non-conductive layer 332 is formed using deposition techniques known in the semiconductor industry. For example, in at least one embodiment, the first non-conductive layer 332 is formed using an atomic layer deposition process (ALD), such that the first non-conductive layer 332 is thinly formed on all surfaces and sidewalls of the entire first conductive layer 328.
[0180] After the third step 306 (forming the first non-conductive layer 332 on the first conductive layer 328), as follows Figure 8D In the fourth step 308 shown, a second conductive layer 334 is formed on the first non-conductive layer 332. The second conductive layer 334 is formed to cover the entire first non-conductive layer 332. The second conductive layer 334 corresponds to... Figure 6A The intermediate conductive layer 220 is shown. The second conductive layer 334 is formed using deposition techniques known in the semiconductor industry. For example, in at least one embodiment, the second conductive layer 334 is formed using a physical vapor deposition process (PVD), wherein the second conductive layer 334 is thinly formed on each surface and sidewall of the entire first non-conductive layer 332.
[0181] After the fourth step 308 (forming the second conductive layer 334 on the first non-conductive layer 332), as follows Figure 8EIn the fifth step 310 shown, a second non-conductive layer 336 is formed on the second conductive layer 334. The second non-conductive layer 336 corresponds to, as shown in the figure, Figure 6A The capacitor structure 214 shown has an upper non-conductive layer 222. A second non-conductive layer 336 is formed using deposition techniques known in the semiconductor industry. For example, in at least one embodiment, the second non-conductive layer 336 is formed using an atomic layer deposition process (ALD), wherein the second non-conductive layer 336 is thinly formed on the corresponding surface and sidewalls of the entire second conductive layer 334.
[0182] After the fifth step 310 of forming the second non-conductive layer 336, in such a way... Figure 8F In the sixth step 312 shown, a third conductive layer 338 is formed on the second non-conductive layer 336. The third conductive layer 338 corresponds to... Figure 6A The capacitor structure 214 shown has an upper conductive layer 224. A third conductive layer 338 is formed using deposition techniques known in the semiconductor industry. For example, in at least one embodiment, the third conductive layer 338 is formed using a physical vapor deposition (PVD) process, wherein the third conductive layer 338 is thinly formed on the corresponding surface and sidewalls of the entire second non-conductive layer 336. Figure 8F As shown, after the formation of the third conductive layer 338, one or more trenches 326 are completely filled by the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338. After the formation of the third conductive layer 338, one or more notches 340 are present in the third conductive layer 338 and aligned with the one or more previously unfilled trenches 326. The one or more notches 340 are formed when the third conductive layer 338 fills the remaining portions of the one or more trenches 326 that were not previously filled by the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, and the second non-conductive layer 336.
[0183] After the sixth step 312 of forming the third conductive layer 338, as follows Figure 8GIn the seventh step 314 shown, the third conductive layer 338 is polished and planarized to form the upper surface 344 of the third conductive layer 338. The polishing or planarization of the third conductive layer 338 is performed using techniques known in the semiconductor industry. For example, in at least one embodiment, a chemical mechanical polishing (CMP) process is used to polish or planarize the third conductive layer 338, thereby forming the upper surface 344. When the upper surface 344 of the third conductive layer 338 is formed using the CMP process, one or more notches 340 are removed after sufficient polishing of the third conductive layer 338, thereby making the upper surface 344 flat and smooth.
[0184] After step 314 (grinding and planarizing the third conductive layer 338 to refine and form the upper surface 344 of the third conductive layer 338), as follows Figure 8H In step 316, as shown, the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338 are patterned, thereby removing portions of the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338. Removing these corresponding portions of the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338 results in the formation of recesses 346 around and adjacent to one or more stacked structures 348. One or more stacked structures 348 are formed as portions of one or more capacitor structures 214, as discussed in detail earlier herein. The one or more recesses 346 are formed using one or more forming processes known in the semiconductor industry to define the one or more stacked structures 348. For example, in at least one embodiment, a groove 346 is formed by forming a photoresist material on one or more regions of the upper surface 344 of the third conductive layer 338, the one or more regions corresponding to one or more stacked structures 348 to be formed. Once the photoresist material is formed at one or more regions of the upper surface 344 corresponding to one or more stacked structures 348, the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338 are exposed to a chemical etchant (e.g., during a dry etching process), resulting in the removal of the first conductive layer 328, the first non-conductive layer 332, the second conductive layer 334, the second non-conductive layer 336, and the third conductive layer 338, thereby forming one or more grooves 346 and defining one or more stacked structures 348. Figure 8H As shown, one or more stacked structures 348 have a T-shape.
[0185] After the eighth step 316, in which one or more grooves 346 and one or more stacked structures 348 are formed, as follows Figure 8I In the ninth step 318 shown, one or more regions 350 of the second conductive layer 334 are exposed from the second non-conductive layer 336 and the third conductive layer 338. One or more regions 350 correspond to... Figure 6A The capacitor structure 214 shown has an exposed region 256. One or more regions 350 are formed using one or more process techniques known in the semiconductor industry. For example, in at least one embodiment, one or more regions 350 are formed by applying photoresist material along the upper surface of the third conductive layer 338 of one or more stacked structures 348 to one or more regions, while keeping the respective regions of the third conductive layer 338 corresponding to the one or more regions 350 to be formed exposed. The photoresist material is also formed on the third surface 213 of the second dielectric layer 212. The corresponding regions of the third conductive layer 338 and the second non-conductive layer 336 are exposed to a chemical etchant (e.g., during a dry etching process), thereby removing the corresponding portions of the third conductive layer 338 and the second non-conductive layer 336 at the corresponding regions, thereby forming one or more regions 350 of the second conductive layer 334 exposed from the third conductive layer 338 and the second non-conductive layer 336 of the stacked structure 348. The formation of one or more regions 350 of the second conductive layer 334 results in one or more stacked structures 348 now becoming one or more fully formed and completed capacitor structures 214 (e.g., those disclosed herein). Figure 6A Once one or more regions 350 of the second conductive layer 334 are exposed from the third conductive layer 338 and the second non-conductive layer 336 of the stacked structure 348, the photoresist material is removed, thereby obtaining the following... Figure 8I The structure or component shown.
[0186] After the ninth step 318, where one or more stacked structures 348 are now one or more capacitor structures 214, in such a way... Figure 8J In the tenth step 320 shown, a third dielectric layer 226 is formed on the third surface 213 of the second dielectric layer 212 and on one or more stacked structures 348. The third dielectric layer is formed using deposition techniques known in the semiconductor industry. For example, in at least one embodiment, the third dielectric layer 226 is formed by a physical vapor deposition (PVD) process, wherein the third dielectric layer 226 is formed to completely cover one or more stacked structures 348 and the third surface 213 of the second dielectric layer 212.
[0187] After step 320 (forming a third dielectric layer 226 on the third surface 213 of the second dielectric layer 212 and one or more stacked structures 348), as follows Figure 8KIn the eleventh step 322 shown, one or more second interconnect structures 230 and one or more third interconnect structures 232 are formed, extending into and through the third dielectric layer 226 to reach one or more stacked structures 348 (i.e., one or more capacitor structures 214). The one or more second interconnect structures 230 and third interconnect structures 232 are formed using one or more process technologies known in the semiconductor industry. For example, in at least one embodiment, the one or more second interconnect structures 230 and third interconnect structures 232 are formed by sequentially performing one or more etching and conductive forming techniques. The one or more second interconnect structures 230 are coupled to one or more regions 350 of the second conductive layer 334 of the one or more stacked structures 348, and the one or more third interconnect structures 232 are coupled to the third conductive layer 338 of the one or more stacked structures 348.
[0188] After step 322, which forms the second interconnect structure 230 and the third interconnect structure 232, in the following... Figure 8L In the twelfth step 324 shown, a light-emitting device layer 234 is formed on the fourth surface 228 of one or more second interconnect structures 230, one or more third interconnect structures 232, and the third dielectric layer 226. The light-emitting device layer 234 is formed by performing one or more processes and forming techniques and steps to form one or more sub-pixels 202a, 202b, 202c of the pixel array 200 on the fourth surface 228 of one or more second interconnect structures 230, one or more third interconnect structures 232, and the third dielectric layer 226.
[0189] As discussed in detail earlier in this article, with Figure 1B The one or more capacitor structures 114a, 114b, 114c shown are Figure 2 Unlike the one or more capacitor structures 124a, 124b shown (where the overall and total capacitance of capacitor structures 114a, 114b, 114c, 124a, 124b are limited due to the critical dimension (CD) issue discussed earlier), one or more capacitor structures 214 have a higher overall and total capacitance than the corresponding one or more capacitor structures 114a, 114b, 114c. Furthermore, in relation to... Figure 1B The one or more capacitor structures 114a, 114b, 114c shown are Figure 2In the same amount of space, one or more capacitor structures 124a, 124b can be provided with a greater number of capacitor structures 214. Due to the first U-shaped portion 248 of the lower conductive layer 216, the second U-shaped portion 250 of the intermediate conductive layer 220, and the columnar portion 252 of the upper conductive layer 224, one or more capacitor structures 214 have a higher overall or total capacitance relative to one or more capacitor structures 114a, 114b, 114c, 124a, 124b in the same or less space. The first U-shaped portion 248, the second U-shaped portion 250, and the columnar portion 252 allow for the maximization of the dimensions of one or more first walls 240, one or more second walls 242, one or more third walls 244, and one or more fourth walls 246, such that the first capacitor 236 and the second capacitor 238 are higher than the first capacitors 116, 132 and the second capacitors 117, 140, respectively.
[0190] The first U-shaped portion 248, the second U-shaped portion 250, and the columnar portion 252 allow one or more capacitor structures 214 to be smaller than one or more capacitor structures 114a, 114b, 114c, 124a, 124b, thereby enabling a greater number of one or more capacitor structures 214 to be provided within the same amount of space as one or more capacitor structures 114a, 114b, 114c, 124a, 124b. For example, since sub-pixel 202a has a sub-pixel pitch size 205 equal to 20 micrometers (μm), and the size 207 of each capacitor structure 214 is equal to 200 nanometers (nm), the total number of capacitor structures 214 that can be provided within sub-pixel 202a is equal to one hundred, which is greater than when using one or more capacitor structures 114a, 114b, 114c, 124a, 124b (e.g., ...). Figure 1B and Figure 2 The total number of capacitors is shown in the figure. Because one or more capacitor structures 214 have higher capacitance and can provide more capacitor structures within each sub-pixel 202a, 202b, 202c of each pixel 200, when using one or more capacitor structures 114a, 114b, 114c, 124a, 124b, the one or more capacitor structures 214 allow the electronic device to have a more stable and better resolution display. In other words, and in summary, one or more capacitor structures 214 provide higher capacitance, while relative to... Figure 1B and Figure 2The one or more capacitor structures 114a, 114b, 114c, 124a, 124b shown can provide a greater number of capacitor structures within the same space. By having higher capacitance and being able to provide a greater number of one or more capacitor structures 214 in sub-pixel 202a relative to one or more capacitor structures 114a, 114b, 114c, 124a, 124b, the one or more capacitor structures 214 can be used in the display to provide greater stability and functionality.
