Abstract
Description
Background Technology 1. Technical Field
[0001] This disclosure relates in general to packaging and packaging substrates, and more specifically (but not exclusively) to hybrid core substrates having embedded components.
[0002] 2. Relevant Technical Descriptions
[0003] Figure 1 This is a side cross-sectional view of a conventional device 100, which includes a core 102, with multilayer substrates 104 attached above and below the core 102 and electrically connected to each other via vias 106. Figure 1 The disadvantages of using this design are illustrated—that is, when used with large substrates (such as multilayer substrate 104), the core 102 must be relatively thick (e.g., T = 1.2 mm) in order to maintain flatness.
[0004] Therefore, the distance D between components mounted on the top surface (such as IC 108) and components mounted on the bottom surface (such as bypass capacitor 110) is very large, causing bypass capacitor 110 to fail to function effectively due to the resistance, inductance, or capacitance associated with the long metal path between IC 108 and bypass capacitor 110. The same may be true for other components; a large distance D between top-mounted and bottom-mounted components may impair their functionality.
[0005] Therefore, a better method is needed that does not have the drawbacks described above. Summary of the Invention

[0023] Figure 2 This is a side cross-sectional view of a device 200 including a hybrid core substrate with embedded components, according to various aspects of this disclosure. Figure 2 In the example shown, device 200 includes a rigid core 202 having one or more through-core vias 204. On either side of the rigid core 202 is a multilayer laminate structure 206 (which can be constructed using a "multilayer coreless" process). Each multilayer laminate structure 206 is connected to its own additional multilayer structure 208. Figure 2In the example shown, BGA contact 210 is attached to the bottom of multilayer structure 208. One or two multilayer laminates 206 may include cavities in which one or more components 212 may be embedded. Each component 212 may be electrically connected to one or both multilayer laminates 206 (which may be via one of the vias 204) and / or one or both multilayer structures 208 (e.g., via multilayer laminates 206). Figure 2 In the example shown, IC 214 is mounted to a contact on the top surface of the top multilayer structure 208.
[0024] As in Figure 2 As can be seen in the example shown, the thickness T' of the rigid core 202 can be significantly smaller than the thickness T of the standard core 102, and the distance D' from IC 214 to component 212 can be much smaller. Figure 1 The distance D from IC 108 to capacitor 110.
[0025] Figures 3A to 3M Various parts of a process for manufacturing a hybrid core substrate with embedded components according to aspects of this disclosure are illustrated.
[0026] Figure 3A An example is shown of a core 300 having one or more through-core vias 302. In some aspects, the core 300 may be a copper-clad laminate (CCL) core. In some aspects, the vias 302 are created by drilling and copper plating. Figure 3A In the example shown, the chip 300 has undergone a photolithography process to create electrical traces on the top and bottom surfaces.
[0027] Figure 3B A core 304 having a surface material 306 is shown, on which a first set of laminated layers 308 has been constructed. The core 304 (on which the laminated layers 308 are constructed) may be the same core as core 300 or a different core from core 300. The first set of laminated layers 308 may be collectively referred to herein as the first laminated layer structure 308. In some aspects, the first set of laminated layers 308 may include Ajinomoto deposited film (ABF) and / or prepreg (PPG) and may be manufactured by printed circuit board (PCB) or substrate processes. Although Figure 3B The laminate 308 is shown only on top of the core 304, but in some aspects, an additional laminate 308 may also be constructed on the bottom of the core. A surface material 306 allows the first laminate structure 308 to be mechanically separated from the core 304. The surface material 306 may be one or more sacrificial layers. For example, in some aspects, the surface material 306 comprises two thin copper foil layers attached to each other with a weak adhesive.
[0028] Figure 3CThe result of separating the first laminate structure 308 from the core 304 is shown in preparation for manufacturing one or more cavities in which a deep trench capacitor (DTC) or other component can be embedded.
[0029] Figure 3D The result is shown after cavity 310 has been created within laminate 308. In some aspects, cavity 310 can be created using mechanical processes (e.g., using drills, lasers, high-pressure water, or other cutting tools). Although in Figure 3D It is not visible in the cross-section shown, but Figure 3D The laminate 308 on the left side did not completely separate from Figure 3D The laminate 308 on the right is cut off; conversely, when viewed from a top view instead of... Figure 3D When viewed in a cross-sectional view, cavity 310 is typically a hole or insert. In some respects, the depth of cavity 310 can be controlled by adjusting the number of laminated layers 308.
[0030] Figure 3E The result is shown after the laminate 308 is mounted onto the adhesive tape 312 or another temporary substrate, in preparation for inserting one or more components into the cavity 310.
[0031] Figure 3F The result is shown after the first component 314 has been mounted into the cavity 310 by adhesive tape 312. Examples of component 314 include, but are not limited to, multilayer ceramic capacitors (MLCCs), inductors, chips, dies, bare dies, routing bridges, power management integrated circuits (PMICs), and other bare, packaged, or encapsulated devices. As used herein, the term "die" refers to a block of integrated circuits that has been specifically designed to work with other blocks of integrated circuits to form a larger, more complex chip. A die is a bare die configured to physically interconnect with at least one other bare die to function as a single device. A die may perform a specific function and may be combined with other dies that perform other specific functions to form a larger integrated circuit. In some aspects, the first component 314 is placed by a component placement machine (e.g., for packaged devices, etc.) or a die bonding machine (e.g., for bare dies, dies, etc.).
[0032] Figure 3G The results are shown after the first filler layer 316 (such as ABF, PPG or other suitable material) has been placed.
[0033] Figure 3H It shows in Figure 3GThe structure shown is the result of removing strip 312 and attaching it to the top side of core 300 using adhesive layer 318, and attaching the second set of laminates 320 to the bottom side of core 300 using adhesive layer 322 and being covered by the second filler layer 324. In some aspects, adhesive layers 318 and 322 comprise prepreg. The second set of laminates 320 may be collectively referred to herein as the second laminate structure 320. In some aspects, the second set of laminates 320 may comprise ABF and / or PPG and may be manufactured using PCB or substrate processes.
[0034] Figure 3I This shows the drilling of a through hole 326 for connection. Figure 3I The top and bottom surfaces of the structure shown, along with the photolithography process used to create vias through the first fill layer 316 and through the second fill layer 324, result in this structure. Figure 3I In the example shown, the via through the first filler layer 316 is in electrical contact with the first component 314.
[0035] Figure 3J The result is shown after a third laminate structure 328 is created over a first fill layer 318 and a fourth laminate structure 330 is created under a second fill layer 324. In some aspects, the layers in the third laminate structure 328 and / or the fourth laminate structure 330 may include ABF and / or PPG and may be manufactured using PCB or substrate processes. In some aspects, the layers may be created using lamination, drilling, electroplating, photolithography, any front-end processes, or combinations thereof.
[0036] Figure 3K The diagram shows the result after applying a first solder resist (SR) layer 332 to the top surface of the third laminate structure 328 and a second SR layer 334 to the bottom surface of the fourth laminate structure 330, followed by surface treatment to create solder pads. Figure 3K In the example shown, solder mask defined (SMD) pads 336 and non-SMD (NSMD) pads 338 are created; however, alternative embodiments may use only SMD pads or only NSMD pads. The resulting structure is a finished hybrid core substrate with embedded components.
[0037] Figure 3L An example of an application of a hybrid core substrate with embedded components is illustrated. The hybrid core substrate includes a plurality of surface-mount components (e.g., second component 340 and third component 342) mounted to pads on a top surface and contacts 344 (e.g., ball grid array (BGA) etc.) mounted to pads on a bottom surface. Examples of surface-mount components may include, but are not limited to, chips, dies, packages, packaged devices, or other components. It can be seen that the distance from the third component 342 to the first component 314 is less than the distance from the third component 342 to the component mounted to the bottom contact 344.
[0038] For example, the thickness of a typical thick core can range from 0.15 mm to 2.0 mm, excluding laminates, and a thicker core is required when multiple laminates are supported at the top and bottom. Therefore, the distance from the top-mounted component to the bottom-mounted component on either side of a typical thick core can be greater than 3.0 mm.
[0039] In contrast, embedded components typically have a thickness between 0.05 mm and 0.8 mm. For example, Figure 3M The hybrid core substrate shown has, in some aspects, a core 300 with a thickness of 0.1 mm to 0.8 mm, and each of the first, second, third, and fourth laminated structures has a thickness of 0.1 mm to 0.8 mm. Therefore, the total thickness of the hybrid core substrate, including the laminates, can be from 0.6 mm to 2.0 mm. Consequently, the distance from the top-mounted component to the bottom-mounted component does not exceed 2.0 mm, and the distance from the top-mounted component to the embedded component can be as small as 0.1 mm to 0.6 mm.
[0040] Figure 3M An example hybrid core substrate is shown, in which components are embedded in both a laminate 308 above core 300 and a laminate 320 below core 300. Figure 3M In the example shown, the first component 314 is embedded within the laminate 308, and the fourth component 346 is embedded within the laminate 320. It should be understood that multiple components may be embedded within laminates above or below the core 300.
[0041] It should be understood that the foregoing manufacturing process is provided only as a general illustration of some aspects of this disclosure and is not intended to limit this disclosure or the appended claims. Furthermore, many details of the manufacturing process known to those skilled in the art may be omitted or combined in the various overview process sections to facilitate an understanding of the various aspects disclosed without presenting every detail and / or all possible process variations in detail.
[0042] Hybrid core substrates with embedded components offer several advantages over conventional thick core substrates, including but not limited to the following: Hybrid core substrates enable the embedding of large components into the substrate without sacrificing rigidity. Embedding components on either side of a rigid core increases the versatility of embedded passive substrates (EPS). A “multilayer coreless structure with open cavities” configuration (e.g., first laminate structure 308 and second laminate structure 320) provides wiring flexibility within the hybrid core, which helps reduce the number of additional layers (e.g., third laminate structure 328 and fourth laminate structure 330) that need to be built over the cavity 310 and the embedded component 314. The distance between the embedded component 314 and surface-mounted components (such as the third component 342) can be significantly reduced, resulting in better performance. For example, embedded capacitors can be placed closer to the IC that needs them. Another advantage is that because component 314 is embedded in the first laminate structure 328 rather than in the core 300, the core 300 does not have cavities and therefore has better structural integrity. Furthermore, more internal volume in the Core 300 can be used for top-to-bottom wiring. All these improvements allow for a reduction in package size and cost, and the reduced top-to-bottom surface distance improves power and signal integrity, which in turn improves performance and power consumption.
