Abstract

Dry etching can inadvertently lead to two very different types of damage -- voltage stress damage due to dielectric wearout and plasma exposure damage due to particle and photon flux impingement. Voltage stress damage due to charge-up has beem widely studied. It is often areal in distribution; hence, it can be studied even with simple capacitor structures and capacitance-voltage measurements. All plasma exposure damage has an edge-type distribution. Consequently it requires more complicated structures and measurements for its detection.
