Patent ID: 7893528

Claim:
A package structure of a compound semiconductor device, comprising: a thin film substrate including a first conductive film, a second conductive film, and an insulating dielectric material, wherein the insulating dielectric material is between the first conductive film and the second conductive film; a die mounted on a surface of the first conductive film; and a transparent encapsulation material overlaying a first surface of the first conductive film, a first surface of the second conductive film, and the die; wherein the transparent encapsulation material does not overlay a second surface of the first conductive film and a second surface of the second conductive film, the second surface of the first conductive film is opposite the first surface of the first conductive film, and the second surface of the second conductive film is opposite the first surface of the second conductive film; and wherein the material of the insulating dielectric material is SiO, SiN, SiON, TaO, AlO, TiO, AlN, TiN, epoxy resin, silicone or insulating polymer.
