“…These have a density of about 1 to 5 x 10 12 cm -2 , depending on the pro cessing conditions of the oxide layer, and capture cross sections for holes, which are about 1 to 50 x 10 -14 cm 2 depending on E xx [10,36] ; ff has values between 10 -1 , for a hardened oxide, and 1, for sensitive oxide layers, and appears to be a fundamental parameter in maximizing sensitivity.…”
