Description of the Invention: [Technical Field] The present invention relates to a semiconductor device and a manufacturing technique thereof, and relates to a multi-window ball grid array package structure and its manufacture; 5 [Prior Art] In a multi-semiconductor device In the package type, the window ball Grid Array (WBGA) is a window through which the substrate of the carrier wafer is opened, so that the wire bonding port 'electrically connects the substrate and the wafer above it, and Leading to the underside of the substrate to electrically bond the window-type ball grid array package structure. However, due to improper external force or falling to the ground force, it may cause breakage at the joint of the conductive ball, resulting in problems such as poor reliability or component failure. Therefore, a plurality of corners are added to the substrate so that the encapsulant above the substrate can be angled to form an insulating bump bump under the substrate. There will be a serious mold overfill on the manufacturing. As shown in Fig. 1, a conventional multi-window ball grid array 100 mainly comprises a substrate 110, a wafer 120, a die-cut and a plurality of conductive balls 140. The substrate 11 has a 111, an outer surface 112, a central slot 8 extending through the inner surface 11 and the 112, and a plurality of outer pads 119 formed on the outer surface. As shown in Fig. 2, the substrate 1 1 has a glue side 1 14 on the side of the glue side i i 3 in accordance with the mold flow direction of the mold seal. As shown in Figures 1 and 2, the base is specially designed. The grid array is adapted to pass through the window ball to connect to a severely impactful corner 隅 to pass through, however, the outer surface of the inner surface of the structure 130 is spaced from the pair of plates 110 5 Ι 3*452$4. The corners 115 and 116 of the corners of the substrate 110 are adjacent to the glue side 113 of the substrate u, and the remaining corner windows 116 are adjacent to the substrate 110%. The glue side 1 1 4 . The wafer 1 20 is disposed on the inner surface 111 of the substrate 1 1 , and the central pad 122 of the wafer 120 is aligned with the central slot 1 1 8 of the substrate 1 1 以 for a plurality of The bonding wires 116 are electrically connected to the central pads 122 to the substrate 110. The mold sealing body 130 is formed on the inner surface 111 of the substrate 110 and fills the central slot hole 81 to seal the wafer 110 and the bonding wires 116. In addition, the molding compound 130 is further filled into the corner windows 115 and 116, and a plurality of bumps 1 3 2 and 1 3 3 are formed on the outer surface 1 1 2 of the substrate 110 to avoid Damage caused by external force or falling impact. The conductive balls 144 are disposed on the outer surface 丨丨2 of the substrate 110, such that the multi-window ball grid package structure 100 can be externally bonded. Although the bumps 1 3 2 and 1 3 3 can be protected by the Φ between the conductive strips 1 4 0 ', the multi-window ball grid array package structure 1 has an anti-collision effect. However, as shown in FIG. 2, in the process of molding the sealant 130, the mold flow direction of the mold seal 130 is flowing from the glue side 1 1 3 to the outlet. The glue side 1 14 4, and the mold body 丨 3 先 first fills the corner 隅 window u 5 adjacent to the glue side 11 3 | forming the bumps 132 ′ to form the bumps 132 in advance Go to the state of "packing". However, the entire molding compound 13 is still in a "filling state", and flows to the corners 1 1 6 adjacent to the dispensing side U4 to form the bumps 1 3 3, after the entire injection process is completed. Perform 6 I34452$4 "glue filling" and continue to pressurize and heat until the molding compound 丨3 〇 is formed with the bump 13 3 . However, in this case, the bump 1 32 adjacent to the glue side 1 1 3 is opposite to the rubber filling of the ribs 130, the pair of body 130 and the protrusion 133 adjacent to the glue side Η 4 There will be a long glue filling time between 4 τ, and the resulting time difference will cause the bumps adjacent to the glue side 1 1 3 to be ^ 1 μ in the corners of the window U5 to produce a seal over 13 2 , or even The bases to the external ports 1 19 cause some of the conductive balls 140 to be poorly bonded (eg, a, a music shown in Figures 1 and 2).

In the process, a plurality of substrates 4 1 are integrally connected to a substrate strip, and the side windows 411 extend through corresponding scribe lines of the substrate strip (not shown) to make adjacent substrates The side window 4 1 7 of 4 1 0 is in communication' can reduce the number of side windows 417 in the strip pattern of the substrate and contribute to the sealing of the molding compound 430. In this embodiment, the first corner window 4 1 5 and the second corner window 4 16 are connected to the symmetrical side of the substrate 410 and are notched. In the manufacturing process, the first corners 415 are extended over the corresponding scribe lines of the substrate strips such that the first corners 415 of the adjacent substrates 410 are in communication. In various embodiments, as shown in FIG. 16, a plurality of first corner turns 415' are more connectable to the glue side 4 1 3 of the substrate 410, and a plurality of second corner windows 4 1 6 It is more connected to the dispensing side 414 of the substrate 410. In the process, the first corners of the window 4 1 5 ' extend more than the corresponding cutting lane of the bonding side 4丨3 of the substrate 4丨0 and the substrate strip, and the adjacent substrate 4 1 0 The second corners of the window 4 1 6 ' are connected to each other, so that the flow of the mold sealing body 410 is smoother. Referring to Figure 1, the wafer 420 is disposed on the inner surface 4 1 1 of the substrate 410. A plurality of first bonding wires 46 1 and a plurality of second fresh wires 462 are electrically connected to the central fresh pad 422 of the wafer 420 and the peripheral pads 423 of the wafer 420 to the substrate 4 . The molding compound 430 is used to seal the wafer 420. The conductive balls 404 are disposed on the outer surface 412 of the substrate 410. Referring to FIGS. 13 and 14 , the bumper strips 450 5 are formed on the symmetrical sides of the outer surface 4 1 2 of the substrate 4 10 , and The two ends of the rubber-injecting side 4 1 3 extend to the two ends of the rubber-extracting side 4 1 4 and are arranged in parallel with each other, and the anti-collision strips 450 0 are stringed together with the first corners of one side The 隅 window 415 is connected to the second corner 隅 window 416 and to the molding compound 430. Each of the anti-collision strips 5 5 can have a cutting side 45 1 and a floor surface 452 , wherein the cutting sides 45 i are tangent to the symmetrical sides of the substrate 410, and the supporting surfaces 452 are The outer surface 412 of the substrate 410 is substantially parallel to the edge 453 of the support surface 452 and the cutting surface 45 ι has an angle of no more than ninety degrees. Therefore, the first corner 隅 window 415 and the second corner 隅 window 416 have the glue filling time: to avoid the mold flow overflowing adjacent to the first corner window of the glue side 4 i 3 and can The problem of the electrical breakage of the multi-window ball-packing structure 400 when it is dropped is prevented.
