  • Patent number: 11972991
    Abstract: A semiconductor device includes: an inner frame that surrounds an outer circumference of a semiconductor chip; and an outer frame that surrounds an outer circumference of the inner frame; wherein the outer frame is configured with an exterior wall that surrounds the outer circumference of the inner frame, and a fibrous reinforcing member that is wound on an outer circumference of the exterior wall. This prevents the broken pieces of a component that constitutes the semiconductor device from being scattered outside the semiconductor device, thereby not only to achieve improvement in the reliability of the entire system, but also to achieve downsizing of the semiconductor device.
