Abstract

An encapsulated semiconductor device includes a lead frame formed with a flash-proof body. The flash-proof body includes a dam bar formed on atop surface of the lead frame and a tape adhered to a bottom surface of the lead frame, where the dam bar is attached to both the lead frame and the tape. The semiconductor device further includes an encapsulation body having a core-hollowed portion integrated with the lead frame, the core-hollowed portion being bordered by the dam bar and the tape so that a semiconductor chip and conductive elements are exposed in the encapsulation body. A lid can be adhered to the encapsulation body to air-tightly seal the semiconductor chip and encapsulation elements in the core-hollowed portion.
