Abstract:Principle and method for designing high voltage thin film SOI devices with linearly doped drift region are given.LDMOS transistors are fabricated on the SOI wafers with Si film of 0.15μm and buried oxide of 2μm.The dependence of breakdown voltages of the thin film SOI devices on the concentration gradient in the linearly doped drift region is experimentally investigated for the first time.Based on the optimization of the impurity dose in drift region,the breakdown voltage over 612V is observed in the SOI LDMOS transistors with 50μm drift region.
