Patent ID: 7271070

Claim:
A method for producing integrable semiconductor components, in particular transistors, diodes, and logic gates, starting with a weakly p-doped or weakly n-doped semiconductor substrate in the following steps: application of a mask onto the semiconductor substrate for definition of a window delimited by a peripheral edge; production of an n-doped trough in the p-doped semiconductor substrate or p-doped trough in the n-doped semiconductor substrate by means of ion implantation through the mask using a high energy that assures that a weakly p-doped inner area remains on a surface of the p-doped semiconductor substrate or a weakly n-doped inner area remains on a surface of the n-doped semiconductor substrate, wherein a fringe area of the n-doped trough or p-doped trough extends up to the surface of the semiconductor substrate; and production of additional n-doped and/or p-doped areas in the p-doped or n-doped inner area and in the fringe area of the n-doped or the p-doped trough that form the structure of the semiconductor component without a step of additional doping of the p-doped inner area or n-doped inner area to prevent turnover of conductivity type.
