Description of the Invention: [Technical Field to Be Invented] The component belongs to a semiconductor package, and more particularly to a laminated package structure of a semiconductor π device. Dry conductor [Prior Art] 3 circuit (10) die or ^ is a semiconductor (four) (cut, small, approximately rectangular IC component. Generally...round) is encapsulated in a die package structure. , 稞晶会 Du suspected that 4 we are not corroded. This type of button and two beta protects the 1C die, but for some small packages: For use, the package should be more space-consuming than the electrical one. Increasing the thermal divergence of the components > This and the industrial demand for reducing the volume and manufacturing costs are the reasons for the development of the industry. In the field of semiconductors, 'riding = interconnection 2:: the size is shrinking, so the demand for high-density components and uuerconnect is increasing. The library can be used to form a tin-tin bump (10) derb—^曰The germanium technology (fhP-chip) electrically connects the die to the bonding substrate, such as a germanium circuit board. The function of the die package includes the distribution of power, signal distribution, ‘: test, provide protection and support, and so on. As semiconductor components become more and more sturdy, traditional packaging technologies, such as lead frame packaging, ePaac, flexible package, rigid package technology, etc., can not meet the high component density. The fabrication of the wafer requires a ''synthesis 5', such as a Ball Grid Array (BGA) array structure to provide a high-density interconnect configuration in the surface area of the package. The general ball grid array package has a roundabout signal path, which will increase the impedance, and the heat dissipation mechanism will be worsened due to poor heat conduction in 200921889. The package density of the components in the distributed package structure is increased to meet the new generation of electronics. In the product: the new moon has become extraordinarily important. Force betting is on the development of reliable, cost-effective researchers who will have many heart-packaged structures.

The wire layer corresponds to the conductor material (ie, the ^ part) Will be exposed from the protective layer' or - the external connection will be soldered to the interface. The electrode end of the die will be connected to the wire layer, and the other side will be exposed. The semiconductor component damage (Figure 6) is - Stack structure: It: The other grain structure 106 is stacked into three layers to be separately modularized. Each semiconductor element 406, two vertically adjacent grain structures 1〇6 will be connected by the bottom of the top plate. 236 is connected to an external connection (such as solder bump 266), and an underfill resin 416 is used to fill the gap between the two components of the 200921889 gap. Further, the package structure and the 246 are separately from both sides of the package; Dew; to 4; 236, (4) cover in the guide, will make == meter contains too many stacked dielectric layers and sealing material dielectric layer does not have: two problems; second, part of the structure : Under two; = expansion coefficient does not match its clock 蚪 偁 ^ people lack of buffer for releasing stress The thermal cycle of the structure is not reliable during operation. The present invention proposes a stacked package structure to overcome the above problems and has better component performance. - The semiconductor with the die and the conductive wiring can be reduced in cost, and provides high efficiency and high surname (tfk is another purpose to propose a laminate of semiconductor components, port) Package on package (p〇p). In addition, the invention aims to propose a method for manufacturing a convenient and cost-effective conductor laminated package structure.

The conductive vias are coupled to the first layer of the upper and lower surfaces of the first layer package and the second layer of the package a second layer of the surface; the adhesive material is adhered to the lower surface of the first layer package and the upper surface of the second layer package. The first semiconductor package is the same size as the second semiconductor package, and the wrong one The size of the semiconductor die is larger than that of the second semiconductor die. The package structure further includes an isolation base formed on the first layer package with epoxy, FR4/FR5, low cliff (four) fine machine) Or double Malay 5 sub-H emulsion substrate heteropolyimine (B job aleimide Triazine, - chaos = this resin dimension. / ) Temple material is formed, and is filled with glass fiber: formed under the layer package.

The details of the description are only accompanied by the drawings; the schema of Figure 1 will be defined by the accompanying patent claims. The invention of the invention 200921889 [Embodiment] Here The present invention will be described with respect to the specific embodiments of the invention and the description thereof, which are intended to explain the structure or the steps of the present invention, and the specific embodiments of the invention are not limited to the scope of the invention. The preferred embodiment can be widely implemented in other different embodiments. * Month is also - the multi-layer package structure of the conductor element has its proposed structure, as shown in Figure -5 Figure 5. The wire and the metal interconnection are not. In the invention, most of the line drawings of each of the individual packages are the same. The embodiment will use the topmost package to implant each individual package to include a die 211, which is surrounded by the core glue 4, and has two interconnected vias 18 through the core glue 4. The die 2n The surrounding material 8 is formed between the sidewalls of the disk H (four) 4. The interconnecting via 18 is formed by the layer (10) 1 StdbutiGn layer, the ship (4) is bonded to the die ~. The upper layer (bUlld_up layer, ship) is formed in the grain ^, nucleus =: 4 and the top of the redistribution layer 1 下. The lower layer 2 is also the same as the surface. The 16-layer adhesive material is applied under the crystal grain 2n and the sound is added to the surface to provide an adhesive effect. A resilient adhesive material is used to absorb the stress generated by %. A plurality of joints 32 are formed below the lower buildup layer::: the interconnect vias 18 are aligned. The pads 32 may be copper/nickel/gold or pots. The stacked buildup system is formed on the die and the core glue 4, and the glue 4 is formed beside the die h to provide adhesion and protection. The redistribution layer 10 is formed inside the upper buildup layer 12. 200921889 Adhesive material Above the 16 is formed an isolation base 14, which is attached to the upper reinforcement 2. For example, the isolation base = = one, one, one, and the like 'The inside is also broken; the dimension is formed. In an embodiment, the isolation base 14 includes an adhesive layer 16: formed on the lower surface. The redistribution layer 10 is formed by electroplating or etching. The steps will continue until the copper coating reaches the desired thickness, and will extend out of the area to accommodate the grains, the so-called diffusion type; (n_〇Ut). The core glue 4 is coated with the grains 2η. Resin, varnish, silicone, FR5, bismuth or epoxy. The lower package is similar to the upper package, but the lower package is Η, and the upper layer 12 is formed with a connection (4). The second = solder metal interconnection 24 structure Or the conductive connection via is coupled to the upper interface of the (n-1)th layer. In this embodiment, there are at least three rows of joint/ply metal structures. The sandwich structure between the mat and the crucible can be used as a crease between the layers of the mechanical support 8 and the adjacent H6 can be packaged to better heat dissipation. In addition, the mother crystal grains and other layers of the packaged crystal grains may be of different types, such as flash type, passive elements, and the like. The underlying package and the port are more 匕3. The dry tin bumps 3〇 are coupled to the lower pads. An external view of another embodiment of the present invention. Except for the upper package: the wide structure is similar to that in the above embodiment. Please refer to ::: mounted in the isolation base 14 to include a through-hole structure passive 7G member 40. Further, in the embodiment of Fig. 3, the isolation base is removed. For 200921889 in the laminated grain structure and t, the smaller the size of the lower layer grain, the difference between the grain 2η and the grain 2 兰兰μ η in Fig. 1 . The smaller the daily granules, the larger the core glue will occupy. Under this architecture, the core package area of the underlying package will be larger than that of the ^7 type of the package, so that the mechanical support can be strengthened to carry the package of the upper layer. Another embodiment of the present invention is described with respect to the second embodiment. In order to form a via 18b (e.g., a via-level via) through each of the layers in the package, the passive component 40 must be formed over the adhesive material 16a rather than in the original figure. The conductive material 18d is coated on the surface of the through-hole, ', the true filling material 18c will be filled back into the through-hole 18b, and the through-hole 18a is a single-layer through-hole structure compared to the through hole (10). Fig. 5a to Fig. 5c show the sealing structure of the upper layer, the intermediate layer and the lower layer of the present invention. The upper seal has only one side of the build-up layer, while the towel and the lower layer have a build-up structure on both sides. 9 The package is a stacked structure design. The stacking process of each level of the package board is to connect the metal 1 structure by soldering, or to make the via hole and then form a conductive interconnect structure. Each layer of package board can be packaged for final testing, and a diffusion structure gamma squeaking process can be used on each package board. A repairable junction is also provided in the package to be repaired by a de-soldering step (de_soldering). In the package structure of the present invention, the passive components are stacked on the top surface by surface adhesion technology (8 amps & "10", "SMT". In addition, in the present invention, side-by-side sealing and stacking Parallel design of the package structure is also possible. Since each package of the present invention has the same thermal expansion coefficient as the printed circuit board (using the core rubber of the phase 200921889 = BT or FR5), it is punishable to obtain a better package test. The present invention also provides a method of forming a semiconductor die package interconnect structure comprising the steps of: preparing a first layer substrate (the material of the substrate is preferably Βτ or FR5), the substrate having a first layer of die accommodating The through hole is electrically connected to the first layer through the through hole; the adhesive material is adhered to the periphery and the bottom of the first die and at least one first die is embedded in the die receiving through hole of the first layer substrate; Forming a first build-up layer on the upper surface and/or the lower surface of the first die and the first layer substrate, and passing the first layer of the first die of the first die through the first conductive connection via First welding of a layer Metal pad coupling; ^ ★ Prepare a second layer substrate (the material of the substrate is preferably BT or FR5).
