Abstract
A semiconductor device with a temporary discharge path. During back-end-of-line (BEOL), the temporary discharge path discharges a plasma charge collected in a device well, such as a floating p-type well. After processing, the temporary discharge path is rendered non-function, enabling the device to function properly.
