  • 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.

  • Publication number: 20230101475
    Abstract: A substrate processing method is executed by a substrate processing apparatus. The substrate processing apparatus includes a processing tank, and a bubble supply pipe disposed in the processing tank. In the substrate processing method, a substrate holding section immerses a substrate in an alkaline processing liquid stored in the processing tank. A bubble supply section supplies bubbles to the alkaline processing liquid from below the substrate with the substrate immersed in the alkaline processing liquid, the bubbles being supplied from a plurality of bubble holes provided in the bubble supply pipe.
