Semiconductor Component and an Operating Method for a Protective Circuit Against Light Attacks

摘要

A semiconductor component includes a semiconductor substrate, and a doped well having a well terminal and a transistor structure having at least one potential terminal formed in the semiconductor substrate. The transistor structure has a parasitic thyristor, and is at least partly arranged in the doped well. The potential terminal and the well terminal are connected via a resistor.
