IPC: H01L29/78
Filed: 1993-02-26
Abstract: PURPOSE:To increase a breakdown voltage and also improve withstand voltage characteristic by setting impurity concentration of a first well region in such a side where a drain region of transistor is formed lower than the impurity concentration of a second well region in such a side that a channel and a source region of transistor are formed. CONSTITUTION:Using the same resist film 30, deeper ion implantation, intermediate depth ion implantation and shallow ion implantation are continuously performed. In the deeper ion implantation, impurity concentration at a deep position 32 of a substrate 2 is improved to enhance a latchup resistance characteristic. In the intermediate depth ion implantation, impurity concentration at the shallower position 34 is enhanced in comparison with the deeper ion implantation in view of preventing a low concentration part from being formed between the deeper position 32 and the substrate surface. In the shallow ion implantation, impurity concentration is enhanced at the shallower position 36 than the impurity concentration peak position 34 in the intermediate depth ion implantation to adjust a threshold value of the transistor. Thereby, withstand voltage characteristic can be improved.
