Abstract:
A method of creating a semiconductor device package, comprising the steps of:providing a semiconductor device; providing a leadframe, conductive traces having been provided over the surface of said lead frame; providing a ground plane, said ground plane forming a physical and thereto connected interface between said die attach paddle and said lead frame, a plane of said ground plane being interposed between a plane of said die attach paddle and a plane of said lead frame, a plane of said ground plane being parallel with a plane of said die attach paddle, a plane of said ground plane further being parallel with a plane of said lead frame; depositing a layer of die attach paste over the surface of said die attach paddle; mounting said semiconductor device over said layer of die attach paste, thereby mounting said semiconductor device over said die attach paddle; providing first conductive interconnects between points of electrical contact on an active surface of the semiconductor die and said conductive traces having been provided over the surface of said lead frame; providing second conductive interconnects between points of electrical contact on an active surface of the semiconductor die and said ground plane; and providing a mold compound overlying said die attach paddle, further enclosing said ground plane, further enclosing said first and second conductive interconnects, further enclosing said lead frame by a measurable amount.
