  • Patent number: 10163815
    Abstract: A semiconductor wafer contains a plurality of semiconductor die separated by a saw street. A contact pad is formed over an active surface of the semiconductor die. A protective pattern is formed over the active surface of the semiconductor die between the contact pad and saw street of the semiconductor die. The protective pattern includes a segmented metal layer or plurality of parallel segmented metal layers. An insulating layer is formed over the active surface, contact pad, and protective pattern. A portion of the insulating layer is removed to expose the contact pad. The protective pattern reduces erosion of the insulating layer between the contact pad and saw street of the semiconductor die. The protective pattern can be angled at corners of the semiconductor die or follow a contour of the contact pad. The protective pattern can be formed at corners of the semiconductor die.

  • Patent number: 10163747
    Abstract: A semiconductor device has a substrate with a plurality of active semiconductor die disposed over a first portion of the substrate and a plurality of non-functional semiconductor die disposed over a second portion of the substrate while leaving a predetermined area of the substrate devoid of the active semiconductor die and non-functional semiconductor die. The predetermined area of the substrate devoid of the active semiconductor die and non-functional semiconductor die includes a central area, checkerboard pattern, linear, or diagonal area of the substrate. The substrate can be a circular shape or rectangular shape. An encapsulant is deposited over the active semiconductor die, non-functional semiconductor die, and substrate. An interconnect structure is formed over the semiconductor die. The absence of active semiconductor die and non-functional semiconductor die from the predetermined areas of the substrate reduces bending stress in that area of the substrate.
