[0026] A semiconductor package according to the present disclosure will now be described below with reference to the accompanying drawings.
[0027] Figure 1 Illustrated is a cross-sectional view showing a semiconductor package according to one or more embodiments of the present disclosure. Figure 2 The diagram shows Figure 1 Magnified view of part A.
[0028] refer to Figure 1 and Figure 2 , a first redistribution substrate 100 may be provided. The first redistribution substrate 100 may include one first substrate wiring layer or a plurality of first substrate wiring layers stacked on each other. Each first substrate wiring layer may include a first substrate dielectric pattern 110 and a first substrate wiring pattern 120 located in the first substrate dielectric pattern 110. The first substrate wiring pattern 120 in one first substrate wiring layer may be electrically connected to the first substrate wiring pattern 120 located in an adjacent first substrate wiring layer. An example in which the configuration of the first substrate dielectric pattern 110 and the first substrate wiring pattern 120 is explained using one first substrate wiring layer will be described below.
[0029] The first substrate dielectric pattern 110 may include a polymer. The first substrate dielectric pattern 110 may include a dielectric polymer or a photoimageable dielectric (PID). For example, the photoimageable dielectric may include at least one selected from photosensitive polyimide, polybenzoxazole (PBO), phenolic polymer, and benzocyclobutene polymer. For example, the first substrate dielectric pattern 110 may include a dielectric material. For example, the first substrate dielectric pattern 110 may include silicon oxide (SiO), silicon nitride (SiN), silicon oxynitride (SiON), or a dielectric polymer.
[0030] The first substrate wiring pattern 120 may be disposed below the first substrate dielectric pattern 110. The first substrate wiring pattern 120 may extend horizontally below the first substrate dielectric pattern 110. The first substrate wiring pattern 120 may be disposed on the bottom surface of the first substrate dielectric pattern 110. The first substrate wiring pattern 120 may protrude onto the bottom surface of the first substrate dielectric pattern 110. Below the first substrate dielectric pattern 110, the first substrate wiring pattern 120 may be covered by another first substrate dielectric pattern 110 located below the first substrate wiring pattern 120. The first substrate wiring pattern 120 disposed in the lowest first substrate wiring layer may be a substrate pad 122 coupled to an external terminal 150 to be discussed below. As described above, the first substrate wiring pattern 120 may be a pad or line portion of the first substrate wiring layer. In this sense, the first substrate wiring pattern 120 may be a component for horizontal redistribution in the first redistribution substrate 100. The first substrate wiring pattern 120 may include a conductive material. For example, the first substrate wiring pattern 120 may include a metal such as copper (Cu).
[0031] The first substrate wiring pattern 120 may have a mosaic structure. For example, the first substrate wiring pattern 120 may have a via protruding onto the top surface of the first substrate wiring pattern 120. The via may be a component that vertically connects the first substrate wiring patterns 120 of two adjacent first substrate wiring layers to each other. For example, the via may extend from the top surface of the first substrate wiring pattern 120, and may penetrate the first substrate dielectric pattern 110 to couple to the bottom surface of the first substrate wiring pattern 120 in another first substrate wiring layer located above the via. For example, the via may be a component for connecting the first substrate wiring pattern 120 of the topmost first substrate wiring layer to the connection substrate 200 or the module structure MS to be discussed below. For example, the via may extend from the top surface of the first substrate wiring pattern 120, and may penetrate the topmost first substrate dielectric pattern 110 to couple to the connection substrate 200 or the module structure MS to be discussed. In this configuration, the lower portion of the first substrate wiring pattern 120 located on the bottom surface of the first substrate dielectric pattern 110 may be a head used as a horizontal line or a pad, and the via of the first substrate wiring pattern 120 may be a tail. The first substrate wiring pattern 120 may have an inverted T shape.
[0032] A substrate protection layer 130 may be provided. On the bottom surface of the lowermost first substrate wiring layer, the substrate protection layer 130 may cover the substrate pad 122. According to one or more embodiments, the substrate protection layer 130 may expose the bottom surface of the substrate pad 122 while covering the bottom surface of the lowermost first substrate wiring layer. The substrate protection layer 130 may include a dielectric polymer or a photoimageable dielectric (PID).
[0033] The substrate pad 122 may be provided with an external terminal 150 on the bottom surface of the substrate pad 122. For example, the external terminal 150 may penetrate the substrate protection layer 130 to be coupled to the substrate pad 122. The external terminal 150 may include a solder ball or a solder bump. According to the type and arrangement of the external terminal 150, a ball grid array (BGA) type, a fine ball grid array (FBGA) type, or a land grid array (LGA) type semiconductor package may be provided.
[0034] exist Figure 1 In an embodiment, a semiconductor package may be provided in the form of a fan-out panel level package (FO-PLP). For example, a connection substrate 200 may be disposed on a first redistribution substrate 100. The connection substrate 200 may have an opening OP that penetrates the connection substrate 200. For example, the shape of the opening OP may be similar to an opening that connects the top surface and the bottom surface of the connection substrate 200. The opening OP may be defined as indicating a space (region) in which a module structure MS to be discussed below is disposed. The bottom surface of the connection substrate 200 may be in contact with the top surface of the first redistribution substrate 100. However, the embodiments of the present disclosure are not limited thereto, and when the semiconductor package is manufactured in a chip-later scheme, the bottom surface of the connection substrate 200 may be spaced apart from the top surface of the first redistribution substrate 100. For example, the connection substrate 200 may be connected to the first redistribution substrate 100 via separate terminals such as micro solder balls. The following description will focus on Figure 1 Embodiment of the invention.
[0035] The connection substrate 200 may include a base layer 210 and a conductive member 220, which is a line pattern disposed in the base layer 210. The conductive member 220 may have a line structure that vertically connects the first redistribution substrate 100 to the second redistribution substrate 500 to be discussed below. The conductive member 220 may be disposed between the opening OP and the outer side surface of the connection substrate 200. The conductive member 220 may include an upper pad 222, a lower pad 224, and a via 226. The upper pad 222 may be disposed on the top surface of the connection substrate 200. The upper pad 222 may protrude onto the top surface of the connection substrate 200. Unlike what is shown, the upper pad 222 may be buried in the base layer 210, and the top surface of the upper pad 222 may be coplanar with the top surface of the connection substrate 200. The lower pad 224 may be disposed on the bottom surface of the connection substrate 200. The lower pad 224 may be buried in the base layer 210, and the bottom surface of the lower pad 224 may be coplanar with the bottom surface of the connection substrate 200. The via 226 may penetrate the base layer 210, and the upper pad 222 may be electrically connected to the lower pad 224. The base layer 210 may include a polymer. For example, the base layer 210 may include a dielectric polymer or a photoimageable dielectric (PID). For example, the photoimageable dielectric may include at least one selected from photosensitive polyimide, polybenzoxazole (PBO), phenolic polymers, and benzocyclobutene polymers. For example, the base layer 210 may include a dielectric material. For example, the base layer 210 may include silicon oxide (SiO), silicon nitride (SiN), silicon oxynitride (SiON), or a dielectric polymer. The upper pad 222, the lower pad 224, and the via 226 may include a conductor or metal such as copper (Cu).
[0036] The connection substrate 200 may be mounted on the first redistribution substrate 100. For example, the connection substrate 200 may be in contact with the first redistribution substrate 100. The first substrate wiring pattern 120 in the uppermost first substrate wiring layer may penetrate the uppermost first substrate dielectric pattern 110 to be coupled to the lower pad 224. Therefore, the connection substrate 200 may be electrically connected to the external terminal 150 and the module structure MS to be discussed below.
[0037] The module structure MS may be disposed on the first redistribution substrate 100. The module structure MS may be disposed in the opening OP of the connection substrate 200. In this case, the module structure MS may be located on the first redistribution substrate 100 exposed by the opening OP. The module structure MS may be in contact with the top surface of the first redistribution substrate 100. The module structure MS may be spaced apart from the connection substrate 200. For example, the module structure MS may be spaced apart from the inner side surface of the opening OP. The top surface of the module structure MS may be higher in level from the first redistribution substrate 100 than the top surface of the connection substrate 200. For example, the height of the module structure MS may be higher than the height of the connection substrate 200. In an embodiment, the top surface of the module structure MS may be the same as the top surface of the connection substrate 200 or lower than the top surface of the connection substrate 200. For example, the height of the module structure MS may be the same as the height of the connection substrate 200 or lower than the height of the connection substrate 200. The configuration of the module structure MS will be discussed in detail below.
[0038] The module structure MS may include an interposer substrate 310 , and may further include a first semiconductor chip 320 and a second semiconductor chip 330 mounted on the interposer substrate 310 .
[0039] The interposer substrate 310 may include a core portion CP, an upper build-up portion UP, and a lower build-up portion LP.
[0040] The core part CP may extend in one direction. When viewed in a top view, the core part CP may include a core pattern. The present embodiment may exemplarily describe a core part CP having a core pattern, but the embodiments of the present disclosure are not limited thereto. According to one or more embodiments, the core part CP may include two or more core patterns. For example, the interposer substrate 310 may include a plurality of core patterns spaced horizontally from each other or stacked vertically from each other. The core part CP may include a dielectric material. For example, the core part CP may include one of a glass plate, a glass fiber, a ceramic plate, an epoxy resin, and a resin. The core part CP may include a glass fiber. In this case, the interposer substrate 310 may be a glass substrate. For example, the core part CP may include silicon (Si). As another example, the core part CP may include one selected from stainless steel, aluminum (Al), nickel (Ni), magnesium (Mg), zinc (Zn), tantalum (Ta), and any combination of these materials.
[0041] The core part CP may have a vertical connection terminal 311 that vertically penetrates the core part CP. The vertical connection terminal 311 may extend from the top surface of the core part CP to the bottom surface. A portion of the vertical connection terminal 311 may extend to the bottom surface of the core part CP, and another portion of the vertical connection terminal 311 may extend to the top surface of the core part CP. The portions of the vertical connection terminal 311 that protrude onto the bottom and top surfaces of the core part CP may correspond to pads to which the upper build-up part UP and the lower build-up part LP are coupled. Figure 1 and Figure 2 The pad portion extending to the top and bottom surfaces of the core part CP of the vertical connection terminal 311 is illustrated as a component that is independent of the via portion of the vertical connection terminal 311 that penetrates the core part CP, but the embodiments of the present disclosure are not limited thereto. The pad portion and the via portion of the vertical connection terminal 311 can be provided in an integrated form. In an embodiment, the top surface of the vertical connection terminal 311 can be coplanar with the top surface of the core part CP, and the bottom surface of the vertical connection terminal 311 can be coplanar with the bottom surface of the core part CP. The vertical connection terminal 311 can be provided in plurality. The vertical connection terminal 311 may include a conductive material or a metal material, such as copper (Cu).
[0042] The upper build-up portion UP may cover the top surface of the core portion CP. The upper build-up portion UP may include an upper dielectric pattern 312 and an upper wiring pattern 313 sequentially stacked on the top surface of the core portion CP. The upper wiring pattern 313 may be connected to the vertical connection terminal 311 of the core portion CP. For example, the lowermost upper dielectric pattern 312 may contact the top surface of the core portion CP, and some of the upper wiring patterns 313 may penetrate the lowermost upper dielectric pattern 312 to contact the vertical connection terminal 311. The uppermost upper dielectric pattern 312 may expose some of the upper wiring patterns 313, and the exposed upper wiring patterns 313 may correspond to the first interposer pad 314 and the second interposer pad 315, the first interposer pad being used to mount the first semiconductor chip 320 on the interposer substrate 310, and the second interposer pad being used to mount the second semiconductor chip 330 on the interposer substrate 310.
[0043] The lower build-up portion LP may cover the bottom surface of the core portion CP. The lower build-up portion LP may include a lower dielectric pattern 316 and a lower wiring pattern 317 sequentially stacked on the bottom surface of the core portion CP. The lower wiring pattern 317 may be connected to the vertical connection terminal 311. For example, the uppermost lower dielectric pattern 316 may be in contact with the bottom surface of the core portion CP, and some of the lower wiring patterns 317 may penetrate the uppermost lower dielectric pattern 316 to contact the vertical connection terminal 311. Therefore, the upper wiring pattern 313 may be electrically connected to the lower wiring pattern 317 through the vertical connection terminal 311. The lowermost lower dielectric pattern 316 may expose some of the lower wiring patterns 317, and the exposed lower wiring patterns 317 may correspond to the third interposer pad 318 for coupling the interposer substrate 310 to the first redistribution substrate 100.
[0044] The first semiconductor chip 320 and the second semiconductor chip 330 may be mounted on the interposer substrate 310. The first semiconductor chip 320 and the second semiconductor chip 330 may be disposed to be spaced apart from each other. Figure 1 The first semiconductor chip 320 and the second semiconductor chip 330 are depicted as having the same size, but the embodiments of the present disclosure are not limited thereto. According to one or more embodiments, the first semiconductor chip 320 and the second semiconductor chip 330 may have different sizes, such as different heights or widths. The first semiconductor chip 320 and the second semiconductor chip 330 may be of the same type or of different types.
[0045] The first semiconductor chip 320 and the second semiconductor chip 330 may include semiconductor materials such as silicon (Si). The first semiconductor chip 320 and the second semiconductor chip 330 may each include a first circuit layer 322 and a second circuit layer 332. The first circuit layer 322 and the second circuit layer 332 may both include a logic circuit. For example, the first semiconductor chip 320 and the second semiconductor chip 330 may both be logic chips. For example, the first circuit layer 322 and the second circuit layer 332 may both include a memory circuit. For example, the first semiconductor chip 320 and the second semiconductor chip 330 may both be memory chips. For example, the first circuit layer 322 and the second circuit layer 332 may both include a logic circuit, a memory circuit, a passive element, or a combination of these circuits / elements. In one or more embodiments of the present disclosure, if necessary, the first circuit layer 322 and the second circuit layer 332 may include various integrated circuits. The second semiconductor chip 330 may be provided in plurality. In this case, the plurality of second semiconductor chips 330 may have a vertical chip stacking structure.
[0046] The first semiconductor chip 320 and the second semiconductor chip 330 may be in contact with the top surface of the interposer substrate 310. For example, the first chip pad 324 may be disposed on one surface of the first circuit layer 322 of the first semiconductor chip 320. The second chip pad 334 may be disposed on one surface of the second circuit layer 332 of the second semiconductor chip 330. The first semiconductor chip 320 and the second semiconductor chip 330 may be in contact with the interposer substrate 310. For example, the first circuit layer 322 of the first semiconductor chip 320 and the second circuit layer 332 of the second semiconductor chip 330 may be in contact with the upper build-up portion UP of the interposer substrate 310. The first chip pad 324 may be in contact with the first interposer pad 314. The second chip pad 334 may be in contact with the second interposer pad 315.
[0047] The first semiconductor chip 320 may be mounted on the first interposer pad 314. The first chip pad 324 may be directly connected to the first interposer pad 314. For example, a metal-to-metal bond may be implemented between the first chip pad 324 and the first interposer pad 314. In this specification, the term "hybrid bonding" may refer to a bonding in which two components of the same kind are merged at an interface between them. For example, a continuous configuration may be provided between the first chip pad 324 and the first interposer pad 314 coupled to each other, and an invisible interface may exist between the first chip pad 324 and the first interposer pad 314. The first chip pad 324 and the first interposer pad 314 may be formed of the same material and provided in the form of one component. For example, the first chip pad 324 and the first interposer pad 314 may constitute a single entity.
[0048] The second semiconductor chip 330 may be mounted on the second interposer pad 315. The second chip pad 334 may be directly connected to the second interposer pad 315. For example, a metal-to-metal bond may be implemented between the second chip pad 334 and the second interposer pad 315. A continuous configuration may be provided between the second chip pad 334 and the second interposer pad 315 coupled to each other, and an invisible interface may exist between the second chip pad 334 and the second interposer pad 315. The second chip pad 334 and the second interposer pad 315 may be formed of the same material and provided in the form of a component. For example, the second chip pad 334 and the second interposer pad 315 may constitute a single entity.
[0049] The upper wiring pattern 313 of the upper build-up portion UP may connect at least some of the first interposer pads 314 to at least some of the second interposer pads 315. The first semiconductor chip 320 and the second semiconductor chip 330 are electrically connected through the upper build-up portion UP. For example, the first interposer pad 314 on which the first semiconductor chip 320 is mounted may be connected to the second interposer pad 315 on which the second semiconductor chip 330 is mounted through the upper wiring pattern 313. Therefore, a chip-to-chip connection may be achieved between the first semiconductor chip 320 and the second semiconductor chip 330. Since the first semiconductor chip 320 and the second semiconductor chip 330 are connected through the upper build-up portion UP of the interposer substrate 310 located below the first semiconductor chip 320 and the second semiconductor chip 330, a short length electrical connection may be provided between the first semiconductor chip 320 and the second semiconductor chip 330, and the electrical properties of the semiconductor package may be improved.
[0050] The module structure MS may be connected to the first redistribution substrate 100. The module structure MS may be mounted on the first redistribution substrate 100 using a direct bonding method. For example, the third interposer pad 318 of the module structure MS may be disposed on the bottom surface of the interposer substrate 310. The interposer substrate 310 of the module structure MS may be in contact with the first redistribution substrate 100, and the module structure MS may be coupled to the first redistribution substrate 100 by penetrating the uppermost first substrate dielectric pattern 110 to couple to the first substrate wiring pattern 120 of the third interposer pad 318. Thus, the module structure MS may be electrically connected to the connection substrate 200 and the external terminal 150.
[0051] However, the embodiments of the present disclosure are not limited thereto. The bottom surface of the module structure MS may be spaced apart from the top surface of the first redistribution substrate 100. For example, the module structure MS may be connected to the first redistribution substrate 100 via terminals (e.g., micro solder balls) separately disposed on the third interposer pads 318. The following description will focus on Figure 1 Embodiment of the invention.
[0052] According to one or more embodiments of the present disclosure, a glass substrate with high strength may be used as the interposer substrate 310 for connecting the first semiconductor chip 320 and the second semiconductor chip 330 to each other. Therefore, the interposer substrate 310 may suppress warping of the semiconductor package. Therefore, the semiconductor package may have enhanced structural stability.
[0053] The mold layer 400 may be disposed on the connection substrate 200. The mold layer 400 may cover the connection substrate 200 and the module structure MS. The mold layer 400 may fill the opening OP of the connection substrate 200. For example, in the opening OP of the connection substrate 200, the mold layer 400 may fill the gap between the connection substrate 200 and the module structure MS. In one or more embodiments, when the module structure MS and the first redistribution substrate 100 are spaced apart from each other, the mold layer 400 may fill the space (region) between the module structure MS and the first redistribution substrate 100. The mold layer 400 may cover the top surface of the connection substrate 200 and the top surface of the module structure MS. For example, on the interposer substrate 310, the mold layer 400 may cover the first semiconductor chip 320 and the second semiconductor chip 330. In an embodiment, the mold layer 400 may not cover the top surface of the connection substrate 200, for example, any top surface of the first semiconductor chip 320 and the second semiconductor chip 330. The mold layer 400 may include a dielectric polymer material. For example, the molding layer 400 may include epoxy molding compound (EMC).
[0054] In one or more embodiments of the present disclosure, since the module structure MS does not have a separate molding member, the molding layer 400 can be in direct contact with the interposer substrate 310, the first semiconductor chip 320, and the second semiconductor chip 330. Since the module structure MS does not have a separate molding member, the size of the module structure MS can be reduced. In addition, since the first semiconductor chip 320 and the second semiconductor chip 330 of the module structure MS are buried and protected by the molding layer 400 of the semiconductor package, the first semiconductor chip 320 and the second semiconductor chip 330 may not be exposed to external impact, and the structural stability of any one of the module structure MS and the semiconductor package is not reduced.
[0055] The second redistribution substrate 500 may be disposed on the mold layer 400. The second redistribution substrate 500 may include one second substrate wiring layer or a plurality of second substrate wiring layers stacked on each other. Each second substrate wiring layer may include a second substrate dielectric pattern 510 and a second substrate wiring pattern 520 located in the second substrate dielectric pattern 510. The second substrate wiring pattern 520 in one second substrate wiring layer may be electrically connected to the second substrate wiring pattern 520 located in an adjacent second substrate wiring layer. An example in which the configuration of the second substrate dielectric pattern 510 and the second substrate wiring pattern 520 is explained using one second substrate wiring layer will be described below.
[0056] The second substrate dielectric pattern 510 may include a polymer. The second substrate dielectric pattern 510 may include a dielectric polymer or a photoimageable dielectric (PID). For example, the photoimageable dielectric may include at least one selected from photosensitive polyimide, polybenzoxazole (PBO), phenolic polymer, and benzocyclobutene polymer. For example, the second substrate dielectric pattern 510 may include a dielectric material. For example, the second substrate dielectric pattern 510 may include silicon oxide (SiO), silicon nitride (SiN), silicon oxynitride (SiON), or a dielectric polymer.
[0057] The second substrate wiring pattern 520 may be disposed on the second substrate dielectric pattern 510. The second substrate wiring pattern 520 may extend horizontally on the second substrate dielectric pattern 510. The second substrate wiring pattern 520 may be disposed on the top surface of the second substrate dielectric pattern 510. The second substrate wiring pattern 520 may protrude onto the top surface of the second substrate dielectric pattern 510. On the second substrate dielectric pattern 510, the first substrate wiring pattern 520 may be covered by another second substrate dielectric pattern 510 located on the second substrate wiring pattern 520. The lowermost second substrate wiring pattern 520 may be disposed on the top surface of the mold layer 400, and on the mold layer 400, may be covered by the second substrate dielectric pattern 510 located on the lowermost second substrate wiring pattern 520. The second substrate wiring pattern 520 may be a pad or line portion of the second substrate wiring layer. In this sense, the second substrate wiring pattern 520 may be a component for horizontal redistribution in the second redistribution substrate 500. The second substrate wiring pattern 520 may include a conductive material. For example, the second substrate wiring pattern 520 may include copper (Cu). The second substrate wiring patterns 520 of the uppermost second substrate wiring layer may be exposed on the top surface of the second redistribution substrate 500 and may be used as pads on which an external package or electronic device is mounted.
[0058] The second substrate wiring pattern 520 may have a mosaic structure. For example, the second substrate wiring pattern 520 may have a via protruding from the bottom surface of the second substrate wiring pattern 520. The via may be a component that vertically connects the second substrate wiring patterns 520 of two adjacent second substrate wiring layers to each other. For example, the via may extend from the bottom surface of the second substrate wiring pattern 520, and may penetrate the second substrate dielectric pattern 510 to couple to the second substrate wiring pattern 520 of another second substrate wiring layer located below the via. For example, the via may connect the lowermost second substrate wiring pattern 520 to the connection substrate 200. For example, the via may extend from the bottom surface of the second substrate wiring pattern 520, and may penetrate the mold layer 400 to couple to the upper pad 222 of the connection substrate 200. In this configuration, the upper portion of the second substrate wiring pattern 520 located on the top surface of the second substrate dielectric pattern 510 may be a head used as a horizontal line or pad, and the via of the second substrate wiring pattern 520 may be a tail. The second substrate wiring pattern 520 may have a T shape.

The dielectric material may include a dielectric polymer or a thermosetting resin.

[0115] A molding layer 400 may be formed on the carrier substrate 900. The molding layer 400 may fill the space (region) between the connection substrate 200 and the module structure MS. For example, a dielectric member may be injected into the space (region) between the connection substrate 200 and the module structure MS, and then the dielectric member may be cured to form the molding layer 400. According to one or more embodiments, the dielectric member may be formed to cover the module structure MS. Therefore, the first semiconductor chip 320 and the second semiconductor chip 330 of the module structure MS may not be exposed. In an embodiment, a portion of the dielectric member may be provided to cover the top surface of the connection substrate 200. Therefore, the upper pad 222 of the connection substrate 200 may not be exposed. In an embodiment, the molding layer 400 may be formed so as not to cover the top surface of the connection substrate 200.

The formation of the second substrate wiring layer may be repeatedly performed to form the second redistribution substrate 500.
[0117] refer to Fig.26 , can be reversed Fig.25 Thus, the carrier substrate 900 may be disposed over the connection substrate 200 and the module structure MS.
[0118] The carrier substrate 900 may be removed. Thus, the bottom surface of the connection substrate 200 may be exposed, and likewise, the bottom surface of the module structure MS may be exposed. For example, the lower pad 224 of the connection substrate 200 may be exposed, and the third interposer pad 318 of the lower build-up portion LP of the interposer substrate 310 may be exposed.

For example, a dielectric layer may be formed on the top surface of the connection substrate 200 and the top surface of the module structure MS, the dielectric layer may be patterned to form a first substrate dielectric pattern 110, a conductive layer may be formed on the first substrate dielectric pattern 110, and the conductive layer may be patterned to form a first substrate wiring pattern 120, with the result that one first substrate wiring layer may be formed. The formation of the first substrate wiring layer may be repeatedly performed to form the first redistribution substrate 100. The first substrate wiring pattern 120 disposed in the uppermost first substrate wiring layer may be a substrate pad 122. Thereafter, a substrate protection layer 130 covering the substrate pad 122 may be formed on the first substrate wiring layer.
[0120] Return to reference Figure 1 , the substrate protection layer 130 may be patterned to expose the substrate pad 122. The external terminal 150 may be attached to the substrate pad 122.
[0121] In the semiconductor package according to one or more embodiments of the present disclosure, since the semiconductor chip is connected through the upper stacking portion of the interposer substrate located below the semiconductor chip, a short-length electrical connection can be provided between the semiconductor chips, and the electrical properties of the semiconductor package can be improved. In addition, a glass substrate with high strength can be used as an interposer substrate for connecting the semiconductor chip. Therefore, the interposer substrate can suppress the warping of the semiconductor package. Therefore, the semiconductor package can have improved structural stability. In addition, the module structure may not have a separate molding member used only for the module structure, and the size of the module structure can be reduced. In addition, because the molding structure of the semiconductor package buries and covers the semiconductor chip of the module structure, the semiconductor chip may not be exposed to external impact, and the structural stability of either the module structure and the semiconductor package will not be reduced.
[0122] According to one or more embodiments of the present disclosure, the process for forming the module structure can be performed separately from the subsequent process for forming the connection substrate and the subsequent process for embedding the module structure into the connection substrate, and if necessary, the process for forming the module structure can be changed differently. Therefore, the module structure can become modular, and a method for manufacturing a semiconductor package that simplifies the process and reduces the manufacturing cost can be provided.
[0123] Although certain embodiments of the present disclosure have been described and shown, it will be appreciated by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and essential features of the present disclosure. Therefore, the embodiments disclosed above should be considered as illustrative rather than restrictive.
