Abstract
A method and apparatus are provided for protecting a semiconductor device from damage. The method includes the steps of providing a active semiconductor device on a surface of the semiconductor substrate where the active device is surrounded by inactive semiconductor areas and providing a soft metallic guard ring only in the inactive semiconductor areas around the periphery of the active device wherein the metallic guard ring is connected to ground potential and not to the active device.
