Abstract

An integrated circuit arrangement includes a Shockley diode or a thyristor. An inner region of the diode or of the thyristor is completely or partially shielded during the implantation of a p-type well. This gives rise to a Shockley diode or a thyristor having improved electrical properties, in particular with regard to the use as an ESD protection element.
