Abstract:
1. A method for producing a thyristor, the method comprising: forming a first connection region and a second connection region on or above a substrate, wherein the first connection region is doped with dopant atoms of a first conductivity type, and wherein the second connection region is doped with dopant atoms of a second conductivity type; forming a first body region, a second body region and a third body region between the first connection region and the second connection region, wherein the first body region is formed between the first connection region and the third body region, the second body region is formed between the third body region and the second connection region, and the third body region is formed between the first body region and the second body region; forming a first gate region on or above the second body region; forming a second gate region on or above the first body region; wherein the first body region and the second body region are in each case formed as a region with intrinsic conductivity; and wherein the third body region is doped with at least one of dopant atoms of the first conductivity type and dopant atoms of the second conductivity type, wherein the dopant atoms are introduced into the third body region using a halo implantation method or a Vt implantation method or both methods.
