Preferably, the surface of the insulating layer is shaped to be short-circuited. There is a 1,1 surface to stick a fresh line, which can be a flash of a wafer. The 12th wafer of the second wafer 240 can be further enlarged without reducing the installation area of the surface type passive component 220, especially the second wafer 240. The movable surface 241 has an area close to the upper surface 211 of the substrate 210 to constitute a wafer size package. In addition, it can reduce the impact of the smaller hidden wafer 230 on wafer stack and mold flow balance. Another significant effect of the present invention is that it is not required to reduce the size of the second wafer as the number of surface-adhesive passive elements 220 is increased. Conversely, the increase in the setting of the surface-adhesive passive element 220 can increase the second wafer. 240 line support to improve yield. In a second embodiment of the present invention, another multi-chip package construction of a proper substrate die-bonding region is disclosed. Referring to FIG. 6, the multi-chip package structure 300 mainly includes a substrate 310, a plurality of adhesive passive elements 320, a first wafer 330, and a second 34. One of the upper surfaces 31 1 of the substrate 3 1 界定 defines a die bond corresponding to the second wafer 340 . The substrate 310 further has a plurality of pads 3 1 3 formed on a lower surface 3 丨 2 of the substrate 3 1 . The surface-adhesive passive components 320 are disposed at the corners or edges of the die bond and are electrically connected to the substrate 31 by solder paste. The first piece 300 is disposed at a center of the one of the die bonding regions and is electrically connected to the substrate 310. In this embodiment, the first wafer 3 〇 is a flip chip, and a plurality of bumps 331 are formed to be crystallized to the substrate 310 ′ where the back surface 332 of the first wafer 33 系 is The interval is maintained at height H3. Therefore, the surface-adhesive type is adhered to, and the first type of wafer is used in the number 240 process. The surface wafer area, one of the external areas, can be bonded to the non-moving element 13 200837922 piece 3 20 system energy An interval maintaining height H3 is provided to prevent the second wafer 340 from pressing against the first wafer 330. The second wafer 340 is disposed on the surface-adhesive passive component 320 and electrically connected to the substrate 310, and the coverage area of the second wafer 34 corresponds to the die-bonding region. The second wafer 34 has an active surface 341'. The active surface 341 is provided with a plurality of pads 343. A plurality of wires 351 are electrically connected to the second wafer 34 343 to the substrate 3 10 . Preferably, the back surface 342 of the second wafer 340 can be covered with an insulating layer 344 to avoid short circuits of the surface-adhesive passive components 32. In this embodiment, the multi-chip package structure 3 can further include a die attach material 370 that bonds the second die 34 and seals the first die 330 and the surface-adhesive passive components 32. . The multi-chip package structure 300 can further include a sealant 36 〇 that seals the second wafer 340. After the sealant 36 is formed, it can be formed into a sheet shape. Specifically, the multi-chip package structure 300 can be a digital memory card (MicroSDcard), wherein the first chip 330 is a controller chip, and the second chip 34 is a flash memory. Wafer. The multi-chip package structure 300 may further include at least one third wafer 380 stacked on the second wafer 340. The third wafer is a flash memory chip and has substantially the same size as the first wafer. Two wafers 34 〇. The third wafer 380 is stacked on the second wafer 34, and the plurality of pads 381 of the third wafer 380 are located on the upper surface of the main 14 200837922 a, which can be separated by a plurality of bonding wires. 352 electrically connects the pads 381 to the substrate 310. A spacer 390 is disposed between the second wafer 340 and the third wafer 38〇 to provide a wire spacing of the third wafer 38 when stacked in the forward direction, and the third wafer 38 can be prevented from being touched. The wire bonds 3 51 are opposite to the lower ones. Therefore, the multi-chip package structure 300 can hide a small-sized 2-pad 33 〇 and the surface-adhesive passive components 32 〇 in the same layer, and does not affect the second of the larger size. The longitudinal stacking of the wafer 340 with the summer m80 results in an increase in the thickness of the stack. In addition, it is practicable to reduce the size of the second wafer 34 of a larger size and to provide a larger number of surface-adhesive passive elements 32 。.
