Ultra-thin RF LDMOS Power Transistors J.A. Herbsommer, H. Safar, W.Brown, P.Gammel ,O.Lopez, and G. Terefenko Agere Systems, 700 Mountain Ave. Murray Hill NJ 07974, USA. We present the electrical and thermal performance of ultra-thin RF LDMOS devices. Following a proprietary process, we fabricated such devices with a thickness as reduced as 40µm. This results in a reduction of the operating juncti
