Latest Patents
One of Carper's latest patents is for planarized plastic package modules for integrated circuits. This innovation involves a semiconductor module that includes a semiconductor chip, a lead frame with lead fingers, and a down set member within an encapsulant. This design aims to reduce warpage and provide a more planar package by balancing thermal stress between the lead fingers and the encapsulant. The down set member can either be a bent portion of the lead frame or a separate body, such as a dummy semiconductor chip.
Another significant patent by Carper is related to a lead frame having contact pads defined by a polymer insulating film. In this design, the lead frame has conductive fingers with an insulating film located on a first portion of the fingers. The insulating film features openings into which contact pads made of noble metal are provided. This structure inhibits silver migration, offers insulation between wires and the lead frame, and improves adhesion between the plastic package and the lead frame. The single insulating film with openings for the contact pads provides all these essential features.
