In some embodiments, the circuit layers in the second substrate 20 may comprise substrate-level circuit layers (e.g., low-density circuit layers) or bump-level circuit layers (e.g., high-density circuit layers). In some embodiments, the second substrate 20 may additionally comprise a plurality of second conductive pads 22 disposed on the dielectric layers. The second conductive pads 22 may be disposed near, adjacent to, or embedded in and exposed by the dielectric layers, and configured to receive electronic components 26 and / or SMD components 30.

[0025] The semiconductor device package 1 may further include one or more first electronic components 16 disposed on a first substrate 10, and one or more second electronic components 26 disposed on a second substrate 20. The first electronic components 16 may be disposed on a first surface 101 and / or a third surface 102 opposite to the first surface 101 of the first substrate 10. The second electronic components 26 may be disposed on a second surface 201 and / or a fourth surface 202 opposite to the second surface 201 of the second substrate 20.

The first electronic component 16 and the second electronic component 26 may be electrically connected to each other via the first substrate 10, the SMD component 30, and the second substrate 20.
[0026] An SMD assembly 30 is disposed between a first substrate 10 and a second substrate 20. The SMD assembly 30 includes a plurality of connection electrodes 34 that electrically connect the first substrate 10 to the second substrate 20, and the plurality of connection electrodes 34 are electrically disconnected from each other. Each of the connection electrodes 34 is used to provide an independent electrical connection path between the first substrate 10 and the second substrate 20 in a vertical direction, while no electrical connection is formed between the connection electrodes 34 in a horizontal direction. In some embodiments, the SMD assembly 30 may additionally include an insulating substrate 32 having an outer surface 32S covered by the plurality of connection electrodes 34. The outer surface 32S of the insulating substrate 32 defines an internal volume 32V, and the connection electrodes 34 are electrically disconnected from each other inside and outside the internal volume 32V. In some embodiments, when an AC voltage is applied to the connection electrodes 34, the connection electrodes 34 are electrically disconnected from each other inside the internal volume 32V. In some embodiments, adjacent connection electrodes 34 may be parasiticly coupled outside the internal volume 32V of the insulating substrate 32. The SMD component 30 is configured as a support component for maintaining a gap between the first substrate 10 and the second substrate 20. The SMD component 30 is also configured as an interconnect component for interconnecting the first substrate 10 and the second substrate 20. In some embodiments, the SMD component 30 includes, for example... Figure 1A and Figure 1B The two connection electrodes 34 shown are disposed on opposite sides of the insulating substrate 32, and the SMD assembly 30 can be configured as a two-terminal interconnect assembly. The number of connection electrodes 34 can be modified to implement multi-terminal interconnect requirements. Different SMD assemblies 30 can have different numbers of connection electrodes 34 to meet interconnection requirements in different locations of the semiconductor device package 1. Figure 1 For example, two SMD components 30 can be drawn, but the number of SMD components 30 can be modified based on the I / O connection between the first substrate 10 and the second substrate 20.
[0027] In some embodiments, the outer surface 32S of the insulating substrate 32 may include a first outer surface 32S1 facing the first substrate 10, a second outer surface 32S2 facing the second substrate 20, and an outer edge 32S3 connected to the first outer surface 32S1 and the second outer surface 32S2. Each connecting electrode 34 may include a main portion 340 disposed on the outer edge 32S3 of the insulating substrate 32, a first extension portion 341 extending to the first outer surface 32S1 of the insulating substrate 32, and a second extension portion 342 extending to the second outer surface 32S2 of the insulating substrate 32.
[0028] The semiconductor device package 1 may additionally include a plurality of first solder materials 42 disposed on a first substrate 10 and a plurality of second solder materials 44 disposed on a second substrate 20. Each first solder material 42 may partially cover a corresponding connection electrode 34, such as a portion of the main portion 340 and a portion of the first extension portion 341 of the corresponding connection electrode 34, and facilitates bonding the corresponding connection electrode 34 to a corresponding first conductive pad 12. Each second solder material 44 may partially cover a corresponding connection electrode 34, such as a portion of the main portion 340 and a portion of the second extension portion 342 of the corresponding connection electrode 34, and facilitates bonding the corresponding connection electrode 34 to a corresponding second conductive pad 22. In some embodiments, the outer edge 12E of each first conductive pad 12 protrudes beyond the corresponding outer edge 34E of the connection electrode 34, and the outer edge 22E of each second conductive pad 22 protrudes beyond the corresponding outer edge 34E of the connection electrode 34. In some embodiments, the first solder materials 42 and the second solder materials 44 are spaced apart from each other such that the first solder materials 42 and the second solder materials 44 do not fuse. Therefore, the amounts of the first solder material 42 and the second solder material 44 can be precisely controlled, thereby minimizing the risk of open circuits and short circuits, increasing tolerance to warpage, and improving yield and reliability. The materials of the first solder material 42 and the second solder material 44 may include, for example, but not limited to, tin (Sn), lead (Pb), silver (Ag), copper (Cu), or alloys thereof. In some embodiments, the materials of the first solder material 42 and the second solder material 44 may contain the same material or different materials.
[0029] The SMD component 30 may be a pre-formed component, formed prior to bonding to the first substrate 10 and / or the second substrate 20. In some embodiments, the SMD component 30 may include discrete components and be disposed between first electronic components 16, between second electronic components 26, or between first electronic components 16 and second electronic components 26. The SMD component 30 may include dummy passive components in which the function of passive components is disabled. By way of example, the SMD component 30 may include dummy resistors with no or negligible resistor function. The dummy resistor may have two or more connection electrodes 34 that are electrically disconnected from each other and disposed on an insulating substrate 32, and no resistive wires, such as resistive films, are disposed in the insulating substrate 32. In some embodiments, the SMD component 30 may include dummy capacitors with no or negligible capacitor function. The dummy capacitor may have two or more connection electrodes 34 that are electrically disconnected from each other and disposed on an insulating substrate 32, and the dielectric constant of the insulating substrate 32, the overlap area of the connection electrodes 34, and the distance between the connection electrodes 34 are selected in a manner that allows for negligible capacitance. In some embodiments, the SMD component 30 may include a dummy inductor with no inductor function or negligible inductor function. The dummy inductor may have two or more connection electrodes 34 that are electrically disconnected from each other and disposed on an insulating substrate 32, and no coil is disposed in the insulating substrate 32.
[0030] The semiconductor device package 1 may further include an encapsulation layer 50 disposed between the first substrate 10 and the second substrate 20 and encapsulating the SMD component 30, the first electronic component 16, and the second electronic component 26. The SMD component 30 may include discrete components and be individually disposed between the first electronic components 16, between the second electronic components 26, or between the first electronic components 16 and the second electronic components 26. Therefore, the SMD component 30 does not obstruct the molding flow of the molding material of the encapsulation layer 50, and the molding material can flow smoothly into the space between the first substrate 10 and the second substrate 20 from any direction parallel to the first surface 101 and the second surface 201, such as the first direction D1 and the second direction D2.
[0031] In some embodiments, a portion of the first electronic component 16 and the second electronic component 26 are further disposed on the third surface 102 of the first substrate 10 and / or the fourth surface 202 of the second substrate 20, and encapsulation layers 52 and / or 54 may be disposed on the third surface 102 of the first substrate 10 and the fourth surface 202 of the second substrate 20. The materials of the encapsulation layers 50, 52, and 54 may comprise organic molding materials, such as epoxy resin. The materials of the encapsulation layers 50, 52, and 54 may be the same or different. In some embodiments, fillers such as silicon oxide fillers may be added to the encapsulation layers 50, 52, and 54 respectively. In some embodiments, the SMD component 30 is a discrete component and the SMD component 30 may be arranged individually. Therefore, the SMD component 30 does not obstruct the mold flow during the formation of the encapsulation layer 50, and the utilization rate of the substrate area can be increased.
[0032] In some embodiments, the semiconductor device package 1 may additionally include an electrical conductor 18, such as a solder ball, disposed on a third surface 102 of the first substrate 10 and configured to electrically connect the first substrate 10 to another electronic device, such as a printed circuit board (PCB).
[0033] The SMD component 30 is configured as both a support component for maintaining the gap between the first substrate 10 and the second substrate 20, and a multi-terminal interconnect component for interconnecting the first substrate 10 and the second substrate 20. Therefore, the size of the semiconductor device package 1 can be reduced. Compared to semiconductor interconnect interposers, the manufacturing cost and package size of the SMD component 30 can be reduced. Furthermore, the SMD component 30 can be formed using, for example, a surface mount technique (SMT) with a gripping operation. Additionally, the SMD component 30 may include discrete components and be individually disposed between the first electronic components 16, between the second electronic components 26, or between the first electronic components 16 and the second electronic components 26. Therefore, the SMD component 30 does not obstruct the molding flow of the molding material of the encapsulation layer 50, and the molding material can flow smoothly into the space between the first substrate 10 and the second substrate 20 from any direction parallel to the first surface 101 and the second surface 201, such as the first direction D1 and the second direction D2.
[0034] The semiconductor device package disclosed herein is not limited to the embodiments described above, and may be implemented according to other embodiments. For the sake of simplicity of this specification and for ease of comparison between various embodiments of this disclosure, similar components in the following embodiments are labeled with the same reference numerals and may not be described further.
[0035] Figure 2A This is a top view of a semiconductor device package 2A according to some embodiments of the present disclosure. Figure 2AAs shown, the SMD assembly 30 of the semiconductor device package 2A includes a plurality of connection electrodes 34 disposed on two opposite sides of an insulating substrate 32. For example, each of the two opposite sides of the insulating substrate 32 is covered by two or more connection electrodes 34. The SMD assembly 30 of the semiconductor device package 2A provides additional I / O connections between the first substrate 10 and the second substrate 20.
[0036] Figure 2B This is a top view of a semiconductor device package 2B according to some embodiments of the present disclosure. Figure 2B As shown, the SMD assembly 30 of the semiconductor device package 2B includes a plurality of connection electrodes 34 disposed on more than two sides of an insulating substrate 32. For example, each of the four sides of the insulating substrate 32 is covered by one or more connection electrodes 34. The SMD assembly 30 of the semiconductor device package 2B provides additional I / O connections between the first substrate 10 and the second substrate 20.
[0037] Figure 3A This is a cross-sectional view of a semiconductor device package 3A according to some embodiments of the present disclosure. Figure 3A As shown, the SMD assembly 30 may include a connection electrode 34. The connection electrode 34 may be disposed on at least one side of the insulating substrate 32. For example, the connection electrode 34 may be disposed on two or four opposite sides of the insulating substrate 32. The number of first conductive pads 12 and second conductive pads 22 may be the same as or different from the number of connection electrodes 34. The outer edge 12E of the first conductive pad 12 is not aligned with the corresponding outer edge 22E of the second conductive pad 22. By way of example, the outer edge 12E of each first conductive pad 12 protrudes beyond the corresponding outer edge 34E of the connection electrode 34, while the outer edge 22E of the second conductive pad 22 is substantially aligned with or recessed from the corresponding outer edge 34E of the connection electrode 34. The asymmetrical design of the first conductive pads 12 and second conductive pads 22 helps to accurately control the position of the first solder material 42 and the second solder material 44 and prevents the first solder material 42 and the second solder material 44 from fusing together. Therefore, the amount of the first welding material 42 and the amount of the second welding material 44 can be accurately controlled, and the risk of open circuit and short circuit can be reduced.
[0038] Figure 3B This is a cross-sectional view of a semiconductor device package 3B according to some embodiments of the present disclosure. Figure 3BAs shown, the outer edge 12E of each first conductive pad 12 is not aligned with the corresponding outer edge 22E of the second conductive pad 22. By way of example, the outer edge 12E of each first conductive pad 12 protrudes beyond the corresponding outer edge 34E of the connecting electrode 34, while the outer edge 22E of the second conductive pad 22 is substantially aligned with or recessed from the corresponding outer edge 34E of the connecting electrode 34. This asymmetrical design of the first conductive pad 12 and the second conductive pad 22 helps to accurately control the position of the first solder material 42 and the second solder material 44, and prevents the first solder material 42 from fusing with the second solder material 44. Therefore, the amount of the first solder material 42 and the amount of the second solder material 44 can be accurately controlled, and the risk of open circuits and short circuits can be reduced.
[0039] Figure 3C This is a cross-sectional view of a semiconductor device package 3C according to some embodiments of the present disclosure. For example... Figure 3C As shown, the outer edge 12E of each first conductive pad 12 is not aligned with the corresponding outer edge 22E of the second conductive pad 22. By way of example, the outer edge 12E of each first conductive pad 12 is substantially aligned with or recessed from the corresponding outer edge 34E of the connecting electrode 34, while the outer edge 22E of the second conductive pad 22 protrudes beyond the corresponding outer edge 34E of the connecting electrode 34. This asymmetrical design of the first conductive pad 12 and the second conductive pad 22 helps to accurately control the position of the first solder material 42 and the second solder material 44, and prevents the first solder material 42 from fusing with the second solder material 44. Therefore, the amount of the first solder material 42 and the amount of the second solder material 44 can be accurately controlled, and the risk of open circuits and short circuits can be reduced.
[0040] Figure 4A This is a cross-sectional view of a semiconductor device package 4A according to some embodiments of the present disclosure. Figure 4A As shown, the length L1 of the first extension 341 is different from the length L2 of the second extension 342. For example, the length L1 of the first extension 341 is less than the length L2 of the second extension 342. The asymmetrical design of the first extension 341 and the second extension 342 helps to accurately control the positions of the first welding material 42 and the second welding material 44, and prevents the first welding material 42 from fusing with the second welding material 44. Therefore, the amount of the first welding material 42 and the amount of the second welding material 44 can be accurately controlled, and the risk of short circuits can be reduced.
[0041] Figure 4B This is a cross-sectional view of a semiconductor device package 4B according to some embodiments of the present disclosure. Figure 4BAs shown, the outer edge 12E of each first conductive pad 12 is not aligned with the corresponding outer edge 22E of the second conductive pad 22. By way of example, the outer edge 12E of each first conductive pad 12 is substantially aligned with or recessed from the corresponding outer edge 34E of the connecting electrode 34, while the outer edge 22E of the second conductive pad 22 protrudes beyond the corresponding outer edge 34E of the connecting electrode 34. Furthermore, the length L1 of the first extension 341 is different from the length L2 of the second extension 342. By way of example, the length L1 of the first extension 341 is less than the length L2 of the second extension 342. The asymmetrical design of the first extension 341 and the second extension 342, combined with the asymmetrical design of the first conductive pad 12 and the second conductive pad 22, helps to accurately control the position of the first welding material 42 and the second welding material 44, and prevents the first welding material 42 from fusing with the second welding material 44. Therefore, the amount of the first welding material 42 and the amount of the second welding material 44 can be accurately controlled, and the risk of open circuits and short circuits can be reduced.
[0042] In some embodiments of this disclosure, a semiconductor device package includes two stacked substrates and an SMD component disposed therebetween. The SMD component is configured as a support component to maintain a gap between the two stacked substrates and also as an interconnect component to electrically connect the two stacked substrates to electronic components disposed on the two stacked substrates. Therefore, the size of the semiconductor device package can be reduced. The SMD component can be readily formed using, for example, a surface mount technology with a gripping operation. The SMD component includes a plurality of connection electrodes that electrically connect one substrate to the other. Each of the connection electrodes allows a corresponding electrical terminal of the first substrate to be electrically connected in a vertical direction to a corresponding electrical terminal of the second substrate, and the connection electrodes are horizontally disconnected from each other. The SMD component may include a plurality of discretely arranged components that do not obstruct the flow of molding material. Therefore, the electronic components and the SMD component can be arranged to maximize substrate area utilization without obstructing the flow of molding material. The SMD component may include dummy passive components in which the function of passive components is disabled. Therefore, the manufacturing cost of the semiconductor device package can be reduced.

For example, if the difference between two values is less than or equal to ±10% of the average of the values, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%, then the two values can be considered “substantially” or “about” the same. For example, "essentially parallel" can refer to an angle range of less than or equal to ±10° relative to 0°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°. Similarly, "essentially perpendicular" can refer to an angle range of less than or equal to ±10° relative to 90°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°.
