Abstract:
A method to form RF devices in the manufacture of an integrated circuit device comprising:providing a substrate; depositing and patterning a top metal level overlying said substrate wherein said top metal level comprises pads and portions of planned RF devices; forming a first passivation layer overlying said top metal level; patterning said first passivation layer to selectively expose said pads and said parts of planned RE devices; forming a dielectric layer overlying said top metal level and said first passivation layer; patterning said dielectric layer to selectively expose said top metal level; depositing and patterning an RF metal level overlying said dielectric layer and said top metal level to thereby complete said RF devices; forming a second passivation layer overlying said RF metal level, said dielectric layer, and said top metal level; and patterning said second passivation layer to expose said pads in said top metal layer.
