Patent ID: 6852585

Claim:
A method for producing a semiconductor circuit arrangement having a circuit element which is formed in an integrated manner in a semiconductor substrate of a first conductivity type and has at least one control terminal and a first electrode terminal and a second electrode terminal, comprising the steps of: forming a well region of the first conductivity type of the at least one control terminal; forming the first electrode terminal by a terminal well and a sub-well region the terminal well being embedded within the semiconductor substrate, said terminal well being of a second conductivity type opposite to the first conductivity type, the sub-well region being of the second conductivity type and being doped more highly than the terminal well, the sub-well region being situated within the terminal well, the sub-well region being formed in a main surface of the semiconductor substrate; and ending the sub-well region which is assigned to the first electrode terminal before the well region of the first conductivity type of the at least one control terminal.
