Patent 7195954 was granted and assigned to Texas Instruments on March, 2007 by the United States Patent and Trademark Office.
A semiconductor device having reduced self and mutual capacitance of bonded wires is provided by coating the wires with a foamed polymer effectively having a very low dielectric constant. Additional benefits are realized by electrically insulating the wires against short-circuiting, by cushioning the wires with a low modulus sheath, and by protecting chip bond pad metallization
