The present invention relates to an integrated circuit package and method of manufacturing an integrated circuit package. In one aspect, the present invention relates to an integrated circuit package including a lead frame having a lead with an inner pad and an outer pad connected by a connection member, wherein a region of the inner pad and a region of the outer pad are separated by a channel extending through a width of the lead. Such an integrated circuit package further includes a semiconductor die electrically coupled with the inner pad of the lead, and an encapsulant material encapsulating at least a portion of said lead frame, wherein a portion of said outer pad is exposed. In another aspect, the present invention relates to a method including providing a matrix of lead frames, each of the lead frames having a lead, forming a channel extending through a width of the lead to create an inner pad, an outer pad and a connection member in the lead, electrically coupling a semiconductor die with the inner pad, and encapsulating at least a portion of the lead frame such that at least a portion of the outer pad is exposed.

Integrated circuit package and method of manufacturing the integrated circuit package

A process for fabricating a cavity-type integrated circuit package. The process includes: supporting an interior portion of each of a plurality of leads, in a mold; supporting a die attach pad in said mold; molding a package body in said mold such that said leads extend from an interior cavity of said package body to an exterior thereof; mounting a semiconductor die to said die attach pad; wire bonding various ones of said leads to said semiconductor die; adding a fill material for covering at least a surface of said interior portion of said leads; and mounting a lid on said package body for enclosing said die in said cavity of said package body.

Premolded cavity IC package
