Substrate 102 includes at least one dielectric layer 120 and a plurality of interconnects 122. Substrate 102 includes a first surface (e.g., a bottom surface) and a second surface (e.g., a top surface).
[0027] The integrated device 103 (e.g., the first integrated device) is coupled to a first surface (e.g., the bottom surface) of the substrate 102 through a plurality of solder interconnects 130. The integrated device 103 may be coupled to the substrate 102 through a plurality of pillar interconnects (not shown) and a plurality of solder interconnects 130. An underfill 132 may be present between the integrated device 103 and the substrate 102. The at least one interconnect die 101 may be coupled to the first surface of the substrate 102 through a plurality of solder interconnects 114. As will be further described below, the at least one interconnect die 101 may be configured to provide a high-density interconnect to the package 100. The encapsulation layer 104 may be coupled to the first surface of the substrate 102. The encapsulation layer 104 may encapsulate (e.g., partially or completely) the integrated device 103 and the at least one interconnect die 101. The encapsulation layer 104 may include a molding, a resin, and / or an epoxy resin. The encapsulation layer 104 may be a member for encapsulation.

The back side of the integrated device 103 may face the board 108. The back side of the integrated device 103 may be covered by the encapsulation layer 104. In some implementations, the back side (e.g., the back side surface) of the integrated device 103 may remain exposed (e.g., not covered by the encapsulation layer 104). Figure 2 An example of how the back side of the integrated device 103 may be exposed is illustrated and described in .
[0028] At least one interconnect die 101 includes a die substrate 110 and a plurality of die interconnects 112. The die substrate 110 may include silicon. The plurality of die interconnects 112 include a pad interconnect 112a (e.g., a pad), a via interconnect 112b (e.g., a via), and a pad interconnect 112c (e.g., a pad). The pad interconnect 112a is coupled to the via interconnect 112b. The via interconnect 112b is coupled to the pad interconnect 112c. The pad interconnect 112a is coupled to a solder interconnect 114a. The solder interconnect 114a is a part of the plurality of solder interconnects 114.

At least one interconnect die 101 may not have active components. At least one interconnect die 101 may be a member for die interconnection.
[0029] The plurality of die interconnects 112 may have a pitch between adjacent die interconnects in the range of about 150 microns-270 microns. The packaging layer 104 may have a thickness (e.g., height) in the range of about 150 microns-300 microns. The plurality of solder interconnects 115 may have a diameter and / or thickness of about 100 microns. The total combined thickness (e.g., height) of the plurality of solder interconnects 114, the at least one interconnect die 101, and the plurality of solder interconnects 115 may be in the range of about 250 microns-400 microns. These dimensions are possible by using at least one interconnect die 101, which (i) helps provide a thinner package 100 that is still able to accommodate bottom-side integrated devices (e.g., having sufficient support height), and (ii) helps provide interconnects with low pitches (e.g., 150 microns-270 microns) in the packaging layer, and thus helps provide high-density wiring (e.g., high-density interconnects) in the packaging layer.
[0030] The integrated device 105 (e.g., the second integrated device) is coupled to the second surface (e.g., the top surface) of the substrate 102 through a plurality of solder interconnects 152. For example, the integrated device 105 may be coupled to the plurality of interconnects 122 of the substrate 102 through the plurality of solder interconnects 152. The integrated device 105 may be coupled to the substrate 102 through a plurality of pillar interconnects (not shown) and the plurality of solder interconnects 152. The integrated device 107 (e.g., the third integrated device) is coupled to the second surface of the substrate 102 through a plurality of solder interconnects 172. For example, the integrated device 107 may be coupled to the plurality of interconnects 122 of the substrate 102 through a plurality of solder interconnects 172. The integrated device 107 may be coupled to the substrate 102 through a plurality of pillar interconnects (not shown) and the plurality of solder interconnects 172. The passive device 109a is coupled to the second surface of the substrate 102 through a plurality of solder interconnects 190a.

For example, the passive device 109b is coupled to the plurality of interconnects 122 of the substrate 102 through the plurality of solder interconnects 190b. The passive device 109c is coupled to the second surface of the substrate 102 through the plurality of solder interconnects 190c. For example, the passive device 109c is coupled to the plurality of interconnects 122 of the substrate 102 through the plurality of solder interconnects 190c. The passive devices (e.g., 109a, 109b, 109c) may include capacitors and / or inductors.
[0031] The encapsulation layer 106 is coupled to the second surface (e.g., the top surface) of the substrate 102. The encapsulation layer 106 may encapsulate the integrated device 105, the integrated device 107, the passive device 109a, the passive device 109b, and the passive device 109c. The encapsulation layer 106 may include a molding, a resin, and / or an epoxy resin. The encapsulation layer 106 may be a member for encapsulation. The encapsulation layer 106 may be provided by using a compression and transfer molding process, a sheet molding process, or a liquid molding process.
[0032] The external metal layer 160 may be coupled to an outer surface of the encapsulation layer 106. The outer surface of the encapsulation layer 106 may include a top surface and a side surface. The external metal layer 160 may also be coupled to a side surface of the substrate 102 and a side surface of the encapsulation layer 104. The external metal layer 160 may be configured to be coupled to ground. The external metal layer 160 may be configured to serve as an electromagnetic interference (EMI) shield for the package 100. The external metal layer 160 may be configured to be coupled to one or more interconnects from the plurality of interconnects 122 of the substrate 102.
[0033] Figure 2 2 illustrates a cross-sectional view of a package 200 including a substrate and high density interconnects. Figure 1 The package 200 is similar to the package 100 and thus includes the same or similar components as the package 100. The package 200 includes at least one interconnect die 201 having the same Figure 1 The at least one interconnect die 101 has a different configuration.
[0034] The package 200 is coupled to the board 108 through a plurality of solder interconnects 115. The board 108 includes at least one board dielectric layer 180 and a plurality of board interconnects 182. The board 108 may include a printed circuit board (PCB).
[0035] Package 200 includes at least one interconnect die 201, substrate 102, integrated device 103, integrated device 105, integrated device 107, passive device 109a, passive device 109b, passive device 109c, packaging layer 104, packaging layer 106, and external metal layer 160. At least one interconnect die 201 is coupled to the first surface of substrate 102 through a plurality of solder interconnects 114.
[0036] At least one interconnect die 201 includes a die substrate 110 and a plurality of die interconnects 112. The die substrate 110 may include silicon. The plurality of die interconnects 112 include pad interconnects 112a (e.g., pads) and via interconnects 112b (e.g., vias). The pad interconnects 112a are coupled to the via interconnects 112b. The pad interconnects 112a are coupled to solder interconnects 114a. The solder interconnects 114a are part of the plurality of solder interconnects 114. The plurality of solder interconnects 114 are coupled to the plurality of die interconnects 112. The via interconnects 112b are coupled to solder interconnects 115a. The solder interconnects 115a are part of the plurality of solder interconnects 115. At least one interconnect die 101 may be a dummy die. Thus, one possible difference between at least one interconnect die 201 and at least one interconnect die 101 is that at least one interconnect die 201 does not include pad interconnect 112c. One advantage of not having pad interconnect 112c is that at least one interconnect die 201 can be thinner than at least one interconnect die 101, which can help reduce the overall thickness of the package. At least one interconnect die 201 can be a dummy die. The interconnect die 201 can not have any transistors. The at least one interconnect die 201 can not have active components. The at least one interconnect die 201 can be a member for die interconnection.
[0037] The plurality of die interconnects 112 of at least one interconnect die 201 may have a pitch between adjacent die interconnects in the range of about 150 microns-270 microns. The packaging layer 104 may have a thickness (e.g., height) in the range of about 150 microns-300 microns. The plurality of solder interconnects 115 may have a diameter and / or thickness of about 100 microns. The total combined thickness (e.g., height) of the plurality of solder interconnects 114, the at least one interconnect die 201, and the plurality of solder interconnects 115 may be in the range of about 250 microns-400 microns. By using at least one interconnect die 201, these dimensions are possible, which (i) helps provide a thinner package 200 that is still able to accommodate bottom-side integrated devices (e.g., having sufficient support height), and (ii) helps provide interconnects with low pitches (e.g., 150 microns-270 microns) in the packaging layer, and thus helps provide high-density wiring (e.g., high-density interconnects) in the packaging layer.
[0038] Another difference between package 200 and package 100 is that the back side of integrated device 103 of package 200 is exposed. Figure 2As shown, at least a portion of the back side of the integrated device 103 is not covered by the encapsulation layer 104. This may be because during the manufacturing process of the package 200, portions of the encapsulation layer 104, portions of the back side of the integrated device 103, and / or portions of the at least one interconnected die 201 may be removed during a grinding and / or polishing process of the bottom side of the package 200. However, it should be noted that in some specific implementations of the package 200, the back side of the integrated device 103 may be covered by the encapsulation layer 104.
[0039] The integrated device (e.g., 103, 105, 107) may include a die (e.g., a bare semiconductor die). The integrated device may include a power management integrated circuit (PMIC). The integrated device may include an application processor. The integrated device may include a modem. The integrated device may include a radio frequency (RF) device, a passive device, a filter, a capacitor, an inductor, an antenna, a transmitter, a receiver, an integrated device based on gallium arsenide (GaAs), a surface acoustic wave (SAW) filter, a bulk acoustic wave (BAW) filter, a light emitting diode (LED) integrated device, a silicon (Si)-based integrated device, a silicon carbide (SiC)-based integrated device, a memory, a power management processor, and / or a combination thereof. The integrated device (e.g., 103, 105, 107) may include at least one electronic circuit (e.g., a first electronic circuit, a second electronic circuit, etc.). The integrated device may include a transistor. The integrated device may be an example of an electrical component and / or an electrical device. In some implementations, the integrated device may be a core particle. The core particles can be manufactured using a process that provides better yields than manufacturing processes for other types of integrated devices, which can reduce the overall cost of manufacturing the core particles. Different core particles can have different sizes and / or shapes. Different core particles can be configured to provide different functions. Different core particles can have different interconnect densities (e.g., interconnects with different widths and / or spacings). In some implementations, several core particles can be used to perform the functionality of one or more chips (e.g., one or more integrated devices). Relative to using a single chip to perform all the functions of a package, using several core particles that perform several functions can reduce the overall cost of the package.
[0040] The package (e.g., 100, 200) may be implemented in a radio frequency (RF) package. The RF package may be a radio frequency front end (RFFE) package. The package (e.g., 100, 200) may be configured to provide wireless fidelity (WiFi) communications and / or cellular communications (e.g., 2G, 3G, 4G, 5G). The package (e.g., 100, 300) may be configured to support a global system for mobile communications (GSM), a universal mobile telecommunications system (UMTS), and / or long term evolution (LTE). The package (e.g., 100, 200) may be configured to send and receive signals having different frequencies and / or communication protocols.
[0041] Having described various interconnect dies, processes for fabricating the interconnect dies will now be described below.
[0042] Exemplary Process for Fabricating Interconnect Dies
[0043] In some implementations, fabricating an interconnect die includes several processes. FIG. 3A to FIG. 3B An exemplary process for providing or manufacturing an interconnect die is illustrated. In some implementations, an FIG. 3A to FIG. 3B The interconnect die 101 may be provided or manufactured using a process. FIG. 3A to FIG. 3B The process of manufacturing any interconnect die (e.g., 201) described in this disclosure.
[0044] It should be noted that FIG. 3A to FIG. 3B The process of the present invention may combine one or more stages to simplify and / or clarify the process for providing or manufacturing the interconnect die. In some implementations, the order of the processes may be changed or improved. In some implementations, one or more of the processes may be replaced or substituted without departing from the scope of the present disclosure.
[0045] like Figure 3A As shown, stage 1 illustrates a state after providing a die substrate 110. The die substrate 110 includes silicon. The die substrate 110 may include a first surface and a second surface. In some implementations, the first surface of the die substrate 110 may be a top surface and the second surface of the die substrate 110 may be a bottom surface. In some implementations, the first surface of the die substrate 110 may be a bottom surface and the second surface of the die substrate 110 may be a top surface.
[0046] Stage 2 illustrates a state after forming a plurality of cavities 302 in the die substrate 110. For example, the plurality of cavities 302 may be formed through the first surface of the die substrate 110. The plurality of cavities 302 may include trenches. The plurality of cavities 302 may extend partially through the thickness of the die substrate 110. The plurality of cavities 302 may be formed using a laser ablation process and / or an etching process.
[0047] Stage 3 illustrates after forming a metal layer 305 in the plurality of cavities 302 and / or on the first surface of the die substrate 110. The metal layer 305 may include copper. The metal layer 305 may be formed using a plating process.
[0048] Stage 4 illustrates a state after portions of metal layer 305 are removed. For example, portions of metal layer 305 coupled to the first surface of die substrate 110 may be removed, leaving metal layer 305 in the plurality of cavities 302. A polishing process may be used to remove portions of metal layer 305. The remaining metal from metal layer 305 in the plurality of cavities 302 may define a plurality of interconnects 112 b, such as Figure 1 and Figure 2 Described in .
[0049] like Figure 3B As shown, stage 5 illustrates a state after forming a metal layer 307 on the first surface of the die substrate 110. The metal layer 307 may be formed using a plating process. The metal layer 307 may be coupled to the metal layer 305. The metal layer 307 may define a plurality of interconnects 112a, such as Figure 1 and Figure 2 Metal layer 307 may represent a front-side interconnect that interconnects the die.
[0050] Stage 6 illustrates a state after thinning the die substrate 110. For example, a portion of the die substrate 110 may be removed, leaving at least the die substrate 110a, so that the bottom side of the metal layer 305 is exposed. In some implementations, a portion of the die substrate 110 may be removed, leaving at least the die substrate 110a and the die substrate 110b. When the die substrate 110b is present, the bottom side of the metal layer 305 is not exposed. A grinding process may be used to remove the portion of the die substrate 110. In some implementations, stage 6 may illustrate an implementation of an interconnect die including an interconnect, and no additional interconnects are formed in, on, or below the die substrate 110. If no additional interconnects are formed, singulation may be performed in a manner similar to that described below at stage 8. As will be further described below, the interconnect die shown in stage 6 may be used to couple to a substrate.
[0051] Stage 7 illustrates a state after forming a metal layer 309 on the second surface of the die substrate 110. The metal layer 309 may be formed using a plating process. The metal layer 309 may be coupled to the metal layer 305. The metal layer 309 may define a plurality of interconnects 112c, such as Figure 1 and Figure 2 Metal layer 309 may represent a backside interconnect of the interconnect die.
[0052] Stage 8 illustrates a state after singulation to form a number of interconnected dies. A mechanical process may be used to singulate the die substrate 110 into a number of interconnected dies (eg, 101). A saw may be used to singulate the die substrate 110.
[0053] Exemplary Process for Fabricating Interconnect Dies
[0054] In some implementations, fabricating an interconnect die includes several processes. FIG. 4A to FIG. 4B An exemplary process for providing or manufacturing an interconnect die is illustrated. In some implementations, an FIG. 4A to FIG. 4B The interconnect die 101 may be provided or manufactured using a process. FIG. 4A to FIG. 4B The process of manufacturing any interconnect die (e.g., 201) described in this disclosure.
[0055] It should be noted that FIG. 4A to FIG. 4B The process of the present invention may combine one or more stages to simplify and / or clarify the process for providing or manufacturing the interconnect die. In some implementations, the order of the processes may be changed or improved. In some implementations, one or more of the processes may be replaced or substituted without departing from the scope of the present disclosure.
[0056] like Figure 4A As shown, stage 1 illustrates a state after providing a die substrate 110. The die substrate 110 includes silicon. The die substrate 110 may include a first surface and a second surface. In some implementations, the first surface of the die substrate 110 may be a top surface and the second surface of the die substrate 110 may be a bottom surface. In some implementations, the first surface of the die substrate 110 may be a bottom surface and the second surface of the die substrate 110 may be a top surface.
[0057] Stage 2 illustrates a state after forming a plurality of cavities 402 in the die substrate 110. For example, the plurality of cavities 402 may be formed through the first surface of the die substrate 110. The plurality of cavities 402 may include trenches. The plurality of cavities 402 may extend partially through the thickness of the die substrate 110. The plurality of cavities 402 may be formed using a laser ablation process and / or an etching process.
[0058] Stage 3 illustrates a state after forming a metal layer 405 in the plurality of cavities 402 and / or on the first surface of the die substrate 110. The metal layer 405 may include copper. The metal layer 405 may be formed using a filling process, wherein the plurality of cavities 402 may be filled with a conductive paste.
[0059] Stage 4 illustrates a state after portions of metal layer 405 are removed. For example, portions of metal layer 405 coupled to the first surface of die substrate 110 may be removed, leaving metal layer 405 in the plurality of cavities 402. A polishing process may be used to remove portions of metal layer 405. The remaining metal from metal layer 405 in the plurality of cavities 402 may define a plurality of interconnects 112 b, such as Figure 1 and Figure 2 Described in .
[0060] like Figure 4BAs shown, stage 5 illustrates a state after forming a metal layer 407 on the first surface of the die substrate 110. The metal layer 407 may be formed using a plating process. The metal layer 407 may be coupled to the metal layer 405. The metal layer 407 may define a plurality of interconnects 112a, such as Figure 1 and Figure 2 Metal layer 407 may represent a front-side interconnect that interconnects the die.
[0061] Stage 6 illustrates a state after thinning the die substrate 110. For example, a portion of the die substrate 110 may be removed, leaving at least the die substrate 110a, so that the bottom side of the metal layer 405 is exposed. In some implementations, a portion of the die substrate 110 may be removed, leaving at least the die substrate 110a and the die substrate 110b. When the die substrate 110b is present, the bottom side of the metal layer 405 is not exposed. A grinding process may be used to remove the portion of the die substrate 110. In some implementations, stage 6 may illustrate an implementation of an interconnect die including an interconnect, and no additional interconnects are formed in, on, or below the die substrate 110.

In some implementations, various components and / or parts in the drawings may be optional.
[0145] The word "exemplary" is used herein to mean "serving as an example, instance or illustration". Any specific implementation or aspect described herein as "exemplary" is not necessarily to be construed as superior or superior to other aspects of the present disclosure. Likewise, the term "aspect" does not require that all aspects of the present disclosure include the features, advantages or modes of operation discussed. The term "coupled" is used herein to refer to a direct or indirect coupling (e.g., mechanical coupling) between two objects. For example, if object A physically contacts object B, and object B contacts object C, objects A and C can still be considered to be coupled to each other, even if they are not in direct physical contact with each other. Object A coupled to object B may be coupled to at least a portion of object B. The term "electrically coupled" may mean that two objects are coupled together directly or indirectly so that an electric current (e.g., signal, power, ground) can be transferred between the two objects. Two electrically coupled objects may or may not have an electric current flowing between the two objects. The use of the terms "first", "second", "third" and "fourth" (and / or anything above the fourth) is arbitrary. Any of the components described may be a first component, a second component, a third component or a fourth component. For example, the component referred to as the second component may be the first component, the second component, the third component, or the fourth component. The terms "encapsulate", "encapsulate" and / or any derivatives refer to an object that may partially encapsulate or completely encapsulate another object. The terms "top" and "bottom" are arbitrary. The component located at the top may be located above the component at the bottom. The top component may be considered as the bottom component, and vice versa. As described in the present disclosure, a first component located "above" a second component may mean that the first component is located above or below the second component, depending on how the bottom or top is arbitrarily defined. In another example, the first component may be located above (e.g., above) a first surface of the second component, and the third component may be located above (e.g., below) a second surface of the second component, wherein the second surface is opposite to the first surface. It should also be noted that the term "above" as used in the context of a component being located on another component in the present application may be used to indicate that a component is on and / or in another component (e.g., on the surface of a component or embedded in a component). Thus, for example, a first component being above a second component may mean: (1) the first component is above the second component, but not directly contacting the second component; (2) the first component is above (e.g., on a surface of) the second component; and / or (3) the first component is in (e.g., embedded in) the second component. A first component that is "in" a second component may be partially in the second component or completely in the second component. A value of about X to XX may refer to a value between X and XX, inclusive. The values between X and XX may be discrete or continuous. As used in the present disclosure, the term "about 'value X'" or "approximately value X" means within 10 percent of 'value X'.For example, a value of about 1 or approximately 1 would mean a value in the range of 0.9 to 1.1.
[0146] In some implementations, an interconnect is an element or component in a device or package that allows or facilitates electrical connection between two points, elements, and / or components.
