In some embodiments, the interconnect structure 123 is disposed on the semiconductor substrate 121 and includes a dielectric layer 1231, a conductive pattern 1232, and an under bump metal 1233. For simplicity, the dielectric layer 1231 is shown as a single dielectric layer, and the conductive pattern 1232 is shown as embedded in the dielectric layer 1231. Nevertheless, from the perspective of the manufacturing process, the dielectric layer 1231 is composed of at least two dielectric layers. The conductive pattern 1232 can be sandwiched between two adjacent dielectric layers. Some of the conductive patterns 1232 may extend vertically through the dielectric layer 1231 to establish electrical connections between different metallization layers of the interconnect structure 123. In some embodiments, the (outermost) dielectric layer 1231 may be patterned to expose the underlying conductive pattern 1232. Optionally, the under bump metal 1233 may be conformally formed in the opening of the (outermost) dielectric layer 1231 that exposes the conductive pattern 1232, and may further extend over a portion of the exposed surface of the (outermost) dielectric layer 1231.

According to some embodiments, the chip 110 is arranged with the active surface 110a (the surface exposing the contact studs 117 or the contact pads 113 when the contact studs 117 are not included) facing the interposer 120.

[0079] In some embodiments, an underfill material 140 may be disposed between the chip 110 and the insert 120 to protect the connector 130 from thermal stress or physical stress and to ensure electrical connection between the chip 110 and the insert 120. In some embodiments, the underfill material 140 is formed by capillary underfill filling (CUF). A dispenser (not shown) may apply a filling material (not shown) along the periphery of the chip 110. In some embodiments, heating or heat treatment may be applied to allow the filling material to penetrate into the gap defined by the connector 130 between the chip 110 and the insert 120 through capillary action. In some embodiments, a curing process is performed to reinforce the underfill material 140. In some embodiments, as Figure 1A As shown in FIG. 1 , a plurality of underfill portions 140 are formed, each portion securing connectors 130 of chip 110. In some alternative embodiments, a single underfill (not shown) may extend under chip 110 depending on the spacing and relative positions of the chips above interposer 120.

[0080] refer to Figure 1A , the encapsulation body 150 is formed above the insert 120 that encapsulates the chip 110 and the underfill 140. In some embodiments, the encapsulation body 150 is formed by completely covering the chip 110 with an encapsulation material (not shown), and then performing a planarization process (e.g., a mechanical grinding process and / or a chemical mechanical polishing step) until the backside surface of the chip is exposed. In some embodiments, the encapsulation material can be a molding compound, a molding underfill, a resin (e.g., an epoxy resin), etc. In some embodiments, the encapsulation material is formed by an overmolding process. In some embodiments, the encapsulation material is formed by a compression molding process. In some embodiments, the encapsulation material may require a curing step.

In some embodiments, the semiconductor package 100 may include Figure 1A The chip shown in the figure may be more or less than the chip 110 and other components (such as dummy dies, stress release layers, interconnect structures, support pillars, etc.). In addition, although the process is currently shown for a chip-on-wafer (CoW) package 100, the present disclosure is not limited to the package structure shown in the figure, and other types of semiconductor packages (such as integrated fan-out (InFO) package, package-on-packages (PoP), etc.) are also meant to be covered by the present disclosure and fall within the scope of the appended claims.

The through hole 213 may be lined with a conductive material forming a through hole 215. In some embodiments, the through hole 215 only partially fills the through hole 213 (for example, lining the edge of the through hole 213), and the through hole 213 is filled with a dielectric filler 217. In some alternative embodiments, the through hole 213 is filled with the through hole 215. In some embodiments, each of the buildup layers 220 or 230 includes a dielectric layer 221 or 231 and a conductive pattern 223 or 233 embedded in the corresponding dielectric layer 221 or 231 and providing electrical connection between opposite sides of the corresponding dielectric layer 221 or 231. In some embodiments, the buildup layers 220 and 230 may independently include a dielectric layer 221 or 231, depending on wiring requirements. Figure 1A 21 and 23. In some embodiments, the through-hole 215 establishes an electrical connection between the conductive pattern 223 of one build-up layer 220 and the conductive pattern 233 of another build-up layer 230. In some embodiments, the circuit substrate 200 is disposed on a support frame SF1, wherein the build-up layer 230 is oriented toward the support frame SF1 and the other build-up layer 220 is exposed for further processing.

In some embodiments, before the ring 400 is mounted on the circuit substrate 200, the ring 400 can be anodized or passivated (e.g., with nickel) to enhance its environmental resistance. In some embodiments, an outer edge 400o of the ring 400 opposite the inner edge 402i is vertically aligned with an outer edge 200e of the circuit substrate 200.

The support column 800 may be placed on a portion of the soldering material 530 via a pick-and-place process. It should be noted that although Figure 1D to Figure 1F The connection terminal 600, the passive device 700, and the support column 800 are shown disposed on the circuit substrate 200 in this order, but the present disclosure is not limited thereto. In some alternative embodiments, the support column 800 may be disposed on the circuit substrate 200 before the passive device 700, the connection terminal 600, or both. In some alternative embodiments, the passive device 700 may be disposed on the circuit substrate 200 first.

[0086] refer to Figure 1F and Figure 1G , in some embodiments, the system can be removed from the support frame SF2, and then the semiconductor device 10 can be obtained. In some embodiments, the semiconductor device 10 includes a semiconductor package 100 connected to a substrate 200, a ring 400 disposed on the circuit substrate 200 and surrounding the semiconductor package 100, and a connection terminal 600 and a support column 800, both of which are disposed on the opposite side of the circuit substrate 200 relative to the semiconductor package 100. In some embodiments, the passive device 700 may also be disposed on the circuit substrate beside the support column 800 and the connection terminal 600. In some embodiments, the connection terminal 600 and the passive device 700 (if included) are electrically connected to the semiconductor package 100 via the circuit substrate 200. On the other hand, the support column 800 may be electrically insulated from the circuit substrate 200 and the semiconductor package 100. In some embodiments, the support column 800 is disposed on the circuit substrate 200, and the circuit substrate 200 is covered with a dielectric layer 231 of the buildup layer 230 further away from the semiconductor package 100. In some embodiments, the connection terminal 600 , the passive device 700 , and the support column 800 are fixed to the circuit substrate 200 via portions of the soldering material 510 , the soldering material 520 , and the soldering material 530 , respectively.

[0087] In some embodiments, Figure 1GAs shown in , the connection terminal 600 may be thicker (protruding further away from the circuit substrate 200) than the support column 800. In some embodiments, the thickness T600 of the connection terminal 600 may be in the range of from 300 microns to 700 microns, and the thickness T800 of the support column 800 may be in the range of from 200 microns to 600 microns. In some embodiments, the thickness T800 of the support column 800 may be as high as 60% to 85% of the thickness T600 of the connection terminal 600. In some embodiments, the thickness T800 of the support column 800 may be 20% to 100% greater than the thickness T700 of the passive device 700. In some embodiments, the thickness T700 of the passive device may be in the range of from 50 microns to 300 microns. In some embodiments, the material of the support column 800 may have a higher melting point than the material of the connection terminal 600. In some embodiments, the melting temperature of the support column 800 may be at least 300°C higher than the melting temperature of the connection terminal 600. For example, the connection terminal 600 may include a solder ball that begins to melt at a temperature ranging from 150° C. to 260° C., and the support column 800 may include aluminum, stainless steel, copper, silicon, or ceramic, and begins to melt at a temperature of approximately over 1000° C. In some embodiments, the connection terminal 600 may be used to integrate the semiconductor device 10 with other components. In some embodiments, the support column 800 may help maintain the standoff height of the connection terminal 600 during a high temperature heating step (e.g., a reflow process).

[0088] For example, Figure 1HA cross-sectional view of an electronic device 15 is depicted in which a semiconductor device 10 is connected to a circuit carrier 900 (e.g., a printed circuit board, a motherboard, etc.). A connecting terminal 600 establishes an electrical connection between a circuit substrate 200 and the circuit carrier 900. A support post 800 and a passive device 700 are also sandwiched between the circuit substrate 200 and the circuit carrier 900. The support post 800 may be electrically insulated from both the circuit carrier 900 and the circuit substrate 200. In some embodiments, the semiconductor device 10 may be fixed to the circuit carrier 900 via a soldering step, a reflow step, or some other process step that requires heating. In some embodiments, the temperature reached during the heating step may cause some warping in the circuit substrate 200. In some embodiments, the profile of the circuit substrate 200 after the soldering or reflow step may have some curvature, with some areas (first areas) being closer to the circuit carrier 900 than other areas (second areas). That is, the first area may be an area of ​​the circuit substrate 200 that becomes closer to the circuit carrier 900 after the soldering or reflow step. In some embodiments, the first area may be referred to as the minimum area in the warpage profile of the circuit substrate 200. In some embodiments, the support post 800 may be disposed on the circuit substrate 200 corresponding to the minimum area of ​​the warpage profile. For example, for a semiconductor device that does not include a support post, the warpage profile may be physically measured, the minimum area of ​​the warpage profile may be determined, and when a similar semiconductor device including the support post 800 is manufactured, the support post 10 may be disposed in the expected minimum area. In some embodiments, the warpage profile may be simulated, and the position of the support post 800 may be determined based on the results of the simulation. In some embodiments, the position of the support post 800 may be determined based on the results of the simulation, and when subsequent batches are manufactured based on the effectively observed warpage, the position may be further refined. In some embodiments, because the support post 800 has a melting temperature higher than the temperature at which the soldering or reflow of the connection terminal 600 is performed, the support post 800 may resist deformation during the soldering or reflow step. That is, the support post 800 may provide mechanical resistance to the warping (bending) of the circuit substrate 200 toward the circuit carrier 900. In some embodiments, by positioning the support pin 800 corresponding to the minimum area of ​​the warpage profile, the observed warpage can be reduced compared to a case where the support pin 800 is not included. In some embodiments, the reduced warpage of the circuit substrate 200 can avoid shortening of the connection terminal 600 that may occur in the minimum area, thereby increasing the reliability of the electronic device including the semiconductor device 10.

In some embodiments, the semiconductor package 100 is a chip-on-wafer (CoW) system, but the present disclosure is not limited thereto. In some embodiments, Figure 1G The semiconductor device 10 and Figure 2 The difference between the semiconductor devices 20 of the present invention is the material that fixes the support column 800 to the circuit substrate 200. Because the support column 800 does not need to be electrically connected to the circuit substrate 200 or the semiconductor package 100, the adhesive portion 532 is used instead of the solder portion 530 of the semiconductor device 10. In some embodiments, the adhesive portion 532 includes a thermoplastic material, a thermosetting material, or a light-curable material. The adhesive portion 532 may include an epoxy resin, a phenolic resin, a polyolefin, or other suitable materials. In some embodiments, the adhesive portion 532 includes an organic adhesive. However, the present disclosure is not limited thereto, and other materials or polymers compatible with the semiconductor processing environment may be used. The adhesive portion 532 may be applied via lamination, spin coating, or other suitable techniques.

That is, the support pillars 802 may be arranged so that the outline of the vertical projection of the semiconductor package 100 along the direction Z orthogonal to the direction X and the direction Y falls on the support pillars 802. In some embodiments, the minimum area of ​​the warpage profile of the circuit substrate 200 may fall along the edge 100e of the semiconductor package 100. In some embodiments, the minimum area in the warpage profile may be caused by the weight of the semiconductor package 100.

[0091] In some embodiments, the support pillars 804 are positioned at the corners of the circuit substrate 200 along the outer edge 200e within the coverage area of ​​the ring 400. In some embodiments, the closest distance between the support pillars 804 disposed at the corners and the closest connection terminals 600 may be arranged along a direction that is oblique to the first direction X and the second direction Y.

[0096] Figure 4Ais a schematic cross-sectional view of an electronic device 85 according to some embodiments of the present disclosure. The electronic device 85 includes a semiconductor device 80 connected to a circuit carrier 900. The semiconductor device 80 includes: a semiconductor package 100 connected to the side 200a of the circuit substrate 200; a cover layer 420 fixed to the side 200a of the circuit substrate 200; and a connection terminal 600 and a passive device 700 disposed on the side 200b of the circuit substrate 200 between the circuit substrate 200 and the circuit carrier 900. In some embodiments, the cover layer 420 is fixed to the circuit substrate 200 by a bonding material 410 disposed at the periphery of the circuit substrate 200. In some embodiments, the cover layer 420 can promote the dissipation of heat generated during the use of the electronic device 85. In some embodiments, the cover layer 420 includes: a cover 422 extending above the semiconductor package 100; a fixing flange 424 extending from the cover 422 to the circuit substrate 200; and a support flange 426 extending from the cover 422 to the circuit carrier 900. The fixing flange 424 contacts the bonding material 410, thereby fixing the cover 420 to the circuit substrate 200. On the other hand, the support flange 426 reaches the circuit carrier 900, which extends along the outer edge 200e of the circuit substrate 200 to the outside of the coverage area of ​​the circuit substrate 200. That is, the support flange 426 may contact the circuit carrier 900 outside the area covered by the circuit substrate 200. In some embodiments, the fixing flange 424 and the support flange 426 are formed as a single piece reaching the circuit substrate 200, wherein the fixing flange 424 ends and the support flange 426 further extends toward the circuit carrier 900. That is, in some embodiments, the support flange 426 may be regarded as a protrusion of the fixing flange 424, wherein a portion of the fixing flange 424 falls on the bonding material 410 on the circuit substrate 200, and the remaining portion of the fixing flange 424 extends beyond the outer edge 200e of the circuit substrate 200 and reaches the circuit carrier 900 as the support flange 426. In some embodiments, the coating 420 is formed integrally from a block of material (e.g., copper) having a higher melting point than the material of the connection terminal 600. In some embodiments, the coating 420 can provide structural support for the electronic device 85 by contacting the circuit carrier 900. In some embodiments, because the coating 420 has a melting temperature higher than the temperature at which the soldering or reflow of the connection terminal 600 is performed, the coating 420 can resist deformation during the soldering or reflow step. That is, the coating 420 can provide mechanical resistance to warping (bending) of the circuit substrate 200 toward the circuit carrier 900. In some embodiments, by including the coating 420 with the support flange 426, the observed warping can be reduced compared to the case where the support flange 426 is not included.In some embodiments, the reduced warping of the circuit substrate 200 may avoid shortening of the connection terminal 600 that may occur in a minimum area, thereby increasing the reliability of the electronic device 85 .

[0097] Figure 4B is a schematic cross-sectional view of an electronic device 95 according to some embodiments of the present disclosure. The electronic device 95 includes a semiconductor device 90 connected to a circuit carrier 900. The semiconductor device 90 includes: a semiconductor package 100 connected to a side 200a of a circuit substrate 200; a cover layer 430 fixed to the side 200a of the circuit substrate 200; and a connection terminal 600 and a passive device 700 disposed on the side 200b of the circuit substrate 200 between the circuit substrate 200 and the circuit carrier 900. In some embodiments, the cover layer 430 is fixed to the circuit substrate 200 by a bonding material 410 disposed on the side 200a of the circuit substrate 200. In some embodiments, the cover layer 430 includes: a cover 432 extending above the semiconductor package 100; a fixing flange 434 extending from the cover 432 to the circuit substrate 200; and a support flange 436 extending from the cover 434 to the circuit carrier 900. The fixing flange 434 contacts the bonding material 410, thereby fixing the coating 430 to the circuit substrate 200. On the other hand, the support flange 436 passes through the circuit substrate 200 to reach the circuit carrier 900. That is, the support flange 436 can pass through the core layer 210 and the dielectric layer 211, dielectric layer 221, and dielectric layer 231 of the buildup layer 220 and the buildup layer 230 to reach the circuit carrier 900. In some embodiments, the circuit substrate 200 can be perforated before the coating 430 is installed to accommodate the support flange 436. In some embodiments, the coating 430 is integrally formed of a block of material (e.g., copper) having a higher melting point than the material of the connection terminal 600. In some embodiments, the coating 430 can provide structural support for the electronic device 95 by contacting the circuit carrier 900. In some embodiments, because the coating 430 has a higher melting temperature than the temperature at which the welding or reflow of the connection terminal 600 is performed, the coating 430 can resist deformation during the welding or reflow step. That is, the coating layer 430 can provide mechanical resistance to the circuit substrate 200 from warping (bending) toward the circuit carrier 900. In some embodiments, the support flange 436 can be made to contact the circuit carrier 900 corresponding to the minimum area of ​​the warping profile. Thereby, the observed warping can be reduced compared to the case where the support flange 436 is not included. In some embodiments, the reduced warping of the circuit substrate 200 can avoid the shortening of the connection terminal 600 that may occur in the minimum area, thereby increasing the reliability of the electronic device 95.

The passive device used as a support may be electrically insulated from the circuit substrate. In some embodiments, the material of the support has a higher melting temperature (begins to melt at a higher temperature) than the material of the connection terminal. In some embodiments, the support may provide mechanical resistance to the circuit substrate that is warped (bent) toward the circuit carrier. In some embodiments, the support may contact the circuit carrier corresponding to the minimum area of ​​the warping profile of the circuit carrier, thereby possibly reducing the observed warping, compared to the case where the support is not included. In some embodiments, the reduced warping of the circuit substrate may avoid the shortening of the connection terminal that potentially exists in the minimum area of ​​the warping profile, thereby increasing the reliability of the device.
