Meets wafer cutting benefits. Preferably, at least one second wafer 240' may be additionally stacked on the first wafer 230 to expand the memory capacity within a limited bonding surface. In the present embodiment, the first wafer 230 and the second wafer 240 are non-volatile memory wafers of the same size and the same amount. The area of the interface (about the lower surface 212 of the wafer carrier 210) is also between 15 and 15 times the active surface 244 of the second wafer 24 . Generally, a second adhesive layer 241 is formed on the active surface 234 of the first wafer 230, which is bonded to the back surface of the second wafer 240, and the second wafer 24 is actively activated. A plurality of pads 242 are formed on the face 44. A plurality of second bonding wires 262 are connected to the pads 242 of the second wafer 240 and the 11.1316687 internal fingers 214 of the wafer carrier 21. As shown in FIG. 4, in the embodiment, one end of the first bonding wires 261 is connected to the side of the inner connecting fingers 214, and one end of the second bonding wires 262 is connected to the inner ends. The other side of the finger 214 is such that the inscribed fingers 214 of the signal communication are connected by the first bonding wire 261 and the second bonding wire 262, and the number of the internal fingers 214 can be reduced. Preferably, due to the space limitation of the wafer size, the edges of the first wafer 230 and the second wafer 24 are too close to one edge of the wafer carrier 210 (the gap between the edges of the edges is only about 400 μm). The connecting finger 214 is a transverse arrangement, that is, the longer side of the inner connecting portion 214 is parallel to the adjacent edge of the wafer carrying surface 21, so the shorter side length of the inner connecting portions 214 will not be sufficient. The second bond that can be used for the wire bond is broken when the wire is bonded. Therefore, in the present embodiment, as shown in FIG. 4, the starting contact 261A (firStb〇nd, or may be referred to as the ball end) of the first bonding wires 261 should be bonded to one of the corresponding internal fingers 214. On the side, the starting contact 262A of the second bonding wires 262 should be joined to the other side of the corresponding internal finger 214, and the starting contacts 261A φ of the first bonding wires 261 and the second bonding wires The starting contact 262A of 262 is arranged in the same direction as the adjacent edge of the wafer blank 210 to effectively utilize the remaining area of the wafer carrier 21 above the surface 211 after the die bonding. In addition, the microelectronic component 220 may be embedded in the first die layer 231 or may be buried in the second die layer 241. More preferably, the first adhesive layer 231 is an adhesive having a plurality of first spacer balls 23 3 for limiting the thickness of the first adhesive layer 23 and making the first wafer 230 parallel to the The wafer carrier 2 i 〇 is capable of bonding the first wafer 203. The first spacer balls 2 3 3 may be electrically insulated 12 1316687 to avoid guiding the third bonding wires 263. In addition, the second adhesive layer 241 formed between the second positive electrode 230 and the second wafer 240 may also contain a plurality of adhesives of the second spacer ball 243 to make the second wafer 240. It is ruined by the "woman" α. Therefore, the first wafer 230 and the first microchip 240 are not skewed after being bonded, and the surface of the sealing body 250 does not have the problem of exposed wafers and exposed gold wires at a limited thickness. Therefore, the thickness of the encapsulant 250 is greater than the thickness of the first wafer 23〇, the second φββ sheet 40, the first viscous layer 23 1 and the second viscous layer 241, and The total thickness of the wafer carrier 210 can be controlled to a condition of not more than 1.0 mm. In the present embodiment, the wafer card 2 further includes a spacer formed on the microelectronic device 220, and the spacer 221 has a thickness greater than an arc height of the third bonding wire 263. The spacer 221 may also be an inner layer of a sweet layer containing a plurality of third spacer balls 222.

The outer contact fingers 313 are located on the lower surface 312, and a plurality of inner contacts 314 are formed on the upper surface 311. The microelectronic component 320 can be a 13.1316687 microprocessor die that can be flip-chip bonded to the upper surface 31 of the wafer carrier 3 10 . The die layer 33 1 is formed on the upper surface 3 of the wafer carrier 3 10 and has a thickness higher than the thickness of the microelectronic component 320 to embed the microelectronic component 320 such that the microelectronic component 320 overlaps.
