Abstract
Abstract A semiconductor device assembly is made without a molded package by using a tape having a patterned insulating layer and a conductive layer joined thereto. A semiconductor die is seated on the conductive layer and electrically connected to leads of the patterned conductive layer. A body frame is positioned around the die and electrical leads and connections, and an encapsulant material is distributed over the frame and within the frame over the die and electrical leads and connections.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
119 words
An integrated circuit package comprising: a flexible die-supporting substrate having a metal layer and an insulative layer, where the metal layer includes lead finger portions and a die-supporting surface area separated from said lead finger portions; an integrated circuit die supported on the metal die-supporting surface area of the die-supporting substrate; a frame body having an annular cross section, the frame body being adhered to the metal layer of the die-supporting substrate with an adhesive epoxy, with the frame body surrounding the die-supporting surface area and the integrated circuit die; and wherein the insulative layer of the substrate includes one or more insulative dams adjacent inner or outer walls of the annular frame body for containing the adhesive epoxy.
