[0067] This disclosure can be understood by referring to the following detailed description in conjunction with the accompanying drawings. It should be noted that, for ease of understanding and for the sake of brevity, many of the drawings in this disclosure depict only a portion of the electronic device, and certain components in the drawings are not drawn to scale. Furthermore, the number and dimensions of the components in the drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure.
[0068] Throughout this specification and the appended claims, certain terms are used to refer to specific elements. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same elements. This document is not intended to distinguish between elements that function identically but have different names.
[0069] In the following description and claims, the words “containing” and “including” are open-ended terms, and therefore should be interpreted as “containing but not limited to…”.
[0070] Furthermore, relative terms such as "below" or "bottom" and "above" or "top" may be used in the embodiments to describe the relative relationship of one element of the figures to another element. It is understood that if the apparatus in the figures is flipped so that it is upside down, the element described as being on the "below" side will become the element on the "above" side.
[0071] In some embodiments disclosed herein, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or to two structures not in direct (indirect) contact, wherein another structure is disposed between the two structures. Furthermore, these terms regarding engagement and connection may also include situations where both structures are movable or both structures are fixed. In addition, the term "coupling" includes the transfer of energy between two structures through direct or indirect electrical connection, or the transfer of energy between two separate structures through mutual induction.
[0072] It should be understood that when an element or membrane is referred to as being "on" or "connected" to another element or membrane, it can be directly on or directly connected to that other element or membrane, or there may be an inserted element or membrane between them (indirect cases). Conversely, when an element is referred to as being "directly" on or "directly connected" to another element or membrane, there may be no inserted element or membrane between them.
[0073] The terms “approximately,” “equal to,” “equivalent to,” “same,” “substantially,” or “roughly” are generally interpreted as being within 20% of a given value or range, or within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. Furthermore, the phrases “range from the first value to the second value” or “range between the first value and the second value” indicate that the range includes the first value, the second value, and other values in between.
[0074] In this disclosure, the area, width, thickness, or height of each component, or the distance or spacing between components, can be measured using an optical microscopy (OM), a scanning electron microscope (SEM), an alpha-step thickness gauge, an ellipsometry, or other suitable methods. Specifically, according to some embodiments, a scanning electron microscope can be used to obtain a cross-sectional structural image including the component to be measured, and to measure the area, width, thickness, or height of each component, or the distance or spacing between components.
[0075] In this disclosure, roughness judgment is defined by SEM observation, where the peaks and valleys of surface undulations on an uneven surface have a distance difference of 0.15 micrometers (μm) to 1 μm. Roughness judgment measurement can involve using SEM, transmission electron microscope (TEM), etc., to observe the surface undulations at an appropriate magnification, and comparing the undulations by taking a sample of unit length (e.g., 10 μm) to determine its roughness range. Here, "appropriate magnification" means that at least one surface can show at least 10 undulating peaks in the field of view at this magnification, indicating a roughness (Rz) or average roughness (Ra).
[0076] As used herein, the terms “film” and / or “layer” can refer to any continuous or discontinuous structure and material (such as materials deposited by the methods disclosed herein). For example, films and / or layers can include two-dimensional materials, three-dimensional materials, nanoparticles, or even partial or complete molecular layers, or partial or complete atomic layers, or atomic and / or molecular clusters. Films or layers may contain materials or layers with pinholes and may be at least partially continuous.
[0077] Although the terms first, second, third… can be used to describe multiple components, the components are not limited to these terms. These terms are used only to distinguish a single component from other components in the specification. The same terms may not be used in the claims, but rather replaced by first, second, third… in the order of the elements declared in the claims. Therefore, in the following description, a first component may be a second component in the claims.
[0078] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.
[0079] It should be understood that the technical features of several different embodiments can be replaced, reorganized, or mixed to complete other embodiments without departing from the spirit of this disclosure.
[0080] The electronic devices disclosed herein may include, but are not limited to, power modules, semiconductor devices, semiconductor packaging devices, display devices, antenna devices, sensing devices, light-emitting devices, or splicing devices. Electronic devices may include bendable or flexible electronic devices. Electronic devices may include electronic components.

[0081] Reference will now be made in detail to the exemplary embodiments disclosed herein, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element symbols are used in the drawings and description to denote the same or similar parts.
[0082] Figure 1A This is a top view schematic diagram of an embodiment of the packaging structure disclosed herein. Figure 1B It is along Figure 1A A schematic cross-sectional view of line II. Figure 2 This diagram illustrates the relationship between the thickness of the semiconductor component from the back side to the second side of the encapsulation layer and the warpage of the encapsulation structure.
[0083] Please refer to the following at the same time. Figure 1A as well as Figure 1B In this embodiment, the encapsulation structure 100 includes a first semiconductor component 110, a second semiconductor component 120, and an encapsulation layer 130. The second semiconductor component 120 is adjacent to the first semiconductor component 110. The encapsulation layer 130 surrounds the first semiconductor component 110 and the second semiconductor component 120. The encapsulation layer 130 has a first thickness T1, and the first semiconductor component 110 has a second thickness T2, wherein the first thickness T1 is greater than the second thickness T2. The difference between the first thickness T1 and the second thickness T2 is greater than half of the first thickness T1 and less than three times the second thickness T2. Viewed from above, the encapsulation layer 130 has a first area A1, the first semiconductor component 110 has a second area A2, and the second semiconductor component 120 has a third area A3, wherein the sum of the second area A2 and the third area A3 is greater than half of the first area A1.
[0084] In detail, the encapsulation structure 100 of this embodiment is disposed on the carrier substrate 10 via the adhesive layer 20, that is, the carrier substrate 10 serves as a support structure to support the encapsulation structure 100. In one embodiment, the carrier substrate 10 is, for example, quartz, glass, stainless steel, sapphire, other suitable materials, or combinations thereof, but is not limited thereto. In one embodiment, the adhesive layer 20 may be a temporary adhesive layer, which may include a thermally-type release material or an optically-type release material with adhesive properties, so that subsequently formed working units, components, or films can be temporarily attached to the adhesive layer 20. For example, the adhesive layer 20 may be a thermal release tape (HRT) or a light-to-heat-conversion (LTHC) release coating. When an optical release material is used to form adhesive layer 20, the optical release material loses its adhesiveness when exposed to radiation, such as ultraviolet light (UV light), allowing components or films formed on it to be peeled off from adhesive layer 20. For example, adhesive layer 20 may be a UV adhesive.
[0085] Furthermore, the second semiconductor component 120 is adjacent to the first semiconductor component 110. Here, "adjacent" means adjacent in the horizontal direction (e.g., the X direction). According to some embodiments, the distance between the first semiconductor component 110 and the second semiconductor component 120 may be greater than or equal to 0.2 * the first length L1 of the second semiconductor component 120 and less than or equal to 1.5 * the first length L1 of the second semiconductor component 120, thereby avoiding signal interference between semiconductor components, but is not limited thereto. The second semiconductor component 120 of this embodiment includes at least one semiconductor cell (schematically shown as a semiconductor cell 122). In one embodiment, a single semiconductor cell 122 may be, for example, a die, a component having a semiconductor structure, but is not limited thereto. In one embodiment, the second semiconductor component 120 may include a plurality of stacked semiconductor cells, and the stacked plurality of semiconductor cells may be, for example, memory (e.g., RAM), but is not limited thereto. In one embodiment, the second semiconductor component 120 may also include conductive pads 124 and an insulating layer 126 located between the conductive pads 124. The conductive pads 124 of the second semiconductor component 120 and the insulating layer 126 located between the conductive pads 124 are contactable with the adhesive layer 20. In one embodiment, the second semiconductor component 120 may include a plurality of stacked semiconductor cells 122, conductive pads 124, and an insulating layer 126 located between the conductive pads 124. The second thickness T2 of the first semiconductor component 110, in cross-sectional view, is the thickness of the first semiconductor component 110 surrounded by the encapsulation layer 130, and this thickness can be measured along the Z direction. The third thickness T3 of the second semiconductor component 120, in cross-sectional view, is the thickness of the second semiconductor component 120 surrounded by the encapsulation layer 130, and this thickness can be measured along the Z direction. In one embodiment, the second thickness T2 of the first semiconductor component 110 is greater than the third thickness T3 of the second semiconductor component 120. In one embodiment, the first semiconductor component 110 may be, for example, the thickest semiconductor component in the package structure 100.
[0086] The encapsulation layer 130 has a first side 131 and a second side 133 opposite to each other, wherein the first side 131 contacts the adhesive layer 20. The active surface 113 of the first semiconductor component 110 and the active surface 123 of the second semiconductor component 120 are substantially coplanar with the first side 131 of the encapsulation layer 130. In one embodiment, the back surface 111 of the first semiconductor component 110 and the back surface 121 of the second semiconductor component 120 are covered by the encapsulation layer 130. The encapsulation layer 130 surrounds the first semiconductor component 110 and the second semiconductor component 120. Here, the encapsulation layer 130 “surrounds” the semiconductor component (e.g., the first semiconductor component 110 or the second semiconductor component 120) can refer to a perspective view (i.e., orthographic projection) in the top view where the encapsulation layer 130 surrounds the semiconductor component, and in a cross-sectional view, “the side surface S1 of the encapsulation layer 130 is adjacent to the side surface S2 of the semiconductor component.” In other words, “the encapsulation layer 130 may include at least one accommodating space to accommodate the semiconductor component.” Figure 1B As shown, the encapsulation layer 130 can directly contact the side surfaces of the first semiconductor component 110 and the second semiconductor component 120. The encapsulation layer 130 provides waterproofing for the first semiconductor component 110 and the second semiconductor component 120, thereby improving the reliability of the encapsulation structure 100. In one embodiment, the ratio of the coefficient of thermal expansion of the encapsulation layer 130 to the coefficient of thermal expansion of a single semiconductor unit 122 is between 1.2 and 3. Through the above design, the risk of separation or breakage between the encapsulation layer 130 and the semiconductor component can be reduced. In one embodiment, the encapsulation layer 130 may include any suitable organic or inorganic material, such as epoxy molding compound (EMC), silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiOxNy), but is not limited thereto.
[0087] Please refer to this again. Figure 1BThe first thickness T1 of the encapsulation layer 130 is the vertical distance (e.g., along the Z direction) between the second side 133 and the first side 131 of the encapsulation layer 120. Since the first semiconductor component 110 and the second semiconductor component 120 can be directly attached to the adhesive layer 20 and approximately flush with the first side 131 of the encapsulation layer 130, the second thickness T2 of the first semiconductor component 110 can also be the vertical distance between the back surface 111 of the first semiconductor component 110 and the first side 131 of the encapsulation layer 130, and the third thickness T3 of the second semiconductor component 120 can also be the vertical distance between the back surface 121 of the second semiconductor component 120 and the first side 131 of the encapsulation layer 130. In one embodiment, the second thickness T2 of the first semiconductor component 110 is less than the first thickness T1 of the encapsulation layer 130, and the third thickness T3 of the second semiconductor component 120 is less than the second thickness T2 of the first semiconductor component 110. In one embodiment, the third thickness T3 of the second semiconductor component 120 can be less than or equal to the first thickness T1 of the encapsulation layer 130.
[0088] On the other hand, the vertical distance between the back surface 111 of the first semiconductor component 110 and the second side 133 of the encapsulation layer 130 is a fourth thickness T4, and the vertical distance between the back surface 121 of the second semiconductor component 120 and the second side 133 of the encapsulation layer 130 is a fifth thickness T5. Here, the fourth thickness T4 is equal to the difference between the first thickness T1 and the second thickness T2, and the fifth thickness T5 is equal to the difference between the first thickness T1 and the thickness T3. More specifically, the fourth thickness T4 is a local thickness of the encapsulation layer 130. Here, "local" refers to the portion of the encapsulation layer 130 whose orthographic projection falls on the first semiconductor component 110, and whose thickness can be measured from the back surface 111 of the first semiconductor component 110 along the normal direction to the second side 133 of the encapsulation layer 130. The fourth thickness T4 is greater than the second thickness T2 of the first semiconductor component 110 and less than three times the first thickness T2 of the first semiconductor component 110. The fifth thickness T5 is a local thickness of the encapsulation layer 130. Here, "partial" refers to the portion of the encapsulation layer 130 whose orthographic projection falls on the second semiconductor component 120, and whose thickness can be measured from the back surface 121 of the second semiconductor component 120 along the normal direction to the second side 133 of the encapsulation layer 130. In one embodiment, the fourth thickness T4 is less than the fifth thickness T5.
[0089] Please refer to this again. Figure 1AViewed from above, the first semiconductor component 110, the second semiconductor component 120, and the encapsulation layer 130 have rectangular shapes. The encapsulation layer 130 has a first top-view area A1, where the first area A1 is equal to the length L multiplied by the width W. Here, the sum of the second top-view area A2 of the first semiconductor component 110 and the third top-view area A3 of the second semiconductor component 120 is greater than half of the first area A1 of the encapsulation layer 130. The "second top-view area A2" and "third top-view area A3" refer to the maximum length of one of the semiconductor components along a direction (e.g., the X direction) multiplied by the maximum width W along a second direction (e.g., the Y direction), where the first direction is perpendicular to the second direction.
[0090] Please refer to Figure 2 In this diagram, B and A will exhibit different degrees of warpage in the encapsulation layer at different scales. B represents the vertical distance between the semiconductor component and the second side of the encapsulation layer (e.g., ...). Figure 1B The fourth thickness T4 in the figure), while A represents the thickness of the semiconductor component (e.g., the thickness of the fourth thickness T4). Figure 1B The second thickness T2 in the diagram. Curves C1, C2, C3, and C4 represent different proportions of semiconductor components per unit area. For example, the proportion of semiconductor components in the package structure of curve C1 is greater than that in the package structure of curve C4. This means the ratio of the projected area of the semiconductor component on the package layer to the area of the package layer. Therefore, it is necessary to select parameters based on the relationship between B and A, which should be close to or fall within the low-risk region, to improve the yield of the package structure 100. For example... Figure 2 As shown, when the semiconductor component is in the packaging layer 130 (see reference) Figure 1B The encapsulation layer 130, whose projected area on the surface is greater than or equal to 50%, is a portion of the total area of the encapsulation layer. (Please refer to [reference]). Figure 1B When the area is 1.5A, the encapsulation layer size can be reduced by 130 (please refer to...). Figure 1B The problem of cracking due to warping of the packaging structure 100 can be addressed by making the packaging structure have better structural reliability.
[0091] In one embodiment, the coefficient of thermal expansion of the semiconductor component is less than that of the encapsulation layer. For example, the coefficient of thermal expansion of the semiconductor component is 5.43, while that of the encapsulation layer is, for example, 7. In this case, when the thickness of the semiconductor component is less than half the thickness of the encapsulation layer, better warpage resistance can be achieved. That is, half the height of the encapsulation structure (i.e., centerline C) should fall on the side of the encapsulation layer 130. Furthermore, in a cross-sectional view (see reference...), Figure 3The centerline C of the package structure is perpendicular to the Z direction, and the extension direction of the centerline C of the package structure passes through the package layer 130. This design allows the semiconductor component to have better warp resistance, but is not limited thereto. The centerline C referred to in this disclosure means that the distance from the second side 133' of the package layer 130 to the centerline C is equal to the distance from one side 210' of the circuit layer 210 to the centerline C, wherein one side 210' of the circuit layer 210 is a surface away from the second side 133' of the package layer 130.
[0092] It should be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals used to represent the same or similar components, and descriptions of the same technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.
[0093] Figure 3 This is a cross-sectional schematic diagram of an electronic device according to an embodiment of this disclosure. Please also refer to... Figure 1B as well as Figure 3 In this embodiment, electronic device 200a includes a package structure 100' and a circuit layer 210. Specifically, electronic device 200a includes a first semiconductor component 110, a second semiconductor component 120, a package layer 130', and a circuit layer 210. The second semiconductor component 120 is adjacent to the first semiconductor component 110.

The insulating layer 212 is ground until the conductive layer 214 is exposed, wherein the insulating layer 212 and the conductive layer 214 define the circuit layer 210. At this time, the first semiconductor component 110a and the second semiconductor component 120a are disposed between the support portion 134c and the circuit layer 210.
[0126] Finally, please refer to Figure 8C A bonding assembly 220 is formed on the circuit layer 210, wherein the circuit layer 210 is located between the encapsulation layer 130c and the bonding assembly 220, and the bonding assembly 220 is electrically connected to the circuit layer 210. The electronic device 200e can be electrically connected to an external circuit through the bonding assembly 220. At this point, the fabrication of the electronic device 200e is complete.
[0127] In summary, in the embodiments disclosed herein, the first thickness of the encapsulation layer is greater than the second thickness of the first semiconductor component, and the difference between the first and second thicknesses is greater than half the first thickness and less than three times the second thickness.
