Patent ID: 7288843

Claim:
A substrate assembly to be placed in an injection mold, the substrate assembly comprising: a substrate; at least one integrated circuit chip on said substrate; and at least one metal layer extending along at least one peripheral edge of said substrate; the injection mold comprising a first part having a cavity for receiving a lower surface of said substrate, and a second part for defining a cavity over an upper surface of said substrate for molding an encapsulation material for encapsulating said at least one integrated circuit chip, at least one peripheral edge of the second part of the injection mold contacting at least one peripheral edge of the upper surface of said substrate including at least one recess for defining at least one slot for venting gases resulting from the encapsulation of said at least one integrated circuit chip; said at least one metal layer contacting the second part of the injection mold and extending along and on both sides of the at least one recess.
