Abstract:
1. A semiconductor body having a first terminal for feeding an upper supply potential and having a first and a second terminal cell, which are formed at a distance from each other, additionally comprising an arrester structure, which is formed between the first and the second terminal cell in a p-doped substrate, the arrester structure comprising: a first and a second p-channel field-effect transistor structure, which are formed in the relevant n-doped wells essentially parallel to the first and second terminal cell; and a diode structure, which is formed with a p-doped region in an additional n-doped well between the n-doped wells of the first and the second p-channel field-effect transistor structure, wherein the diode structure is configured to activate the first and the second p-channel field-effect transistor structure as arrester elements if there is an electrostatic discharge in the semiconductor body.
