Patent ID: 7153736

Claim:
A method of forming a capacitor comprising: forming first capacitor electrode material over a semiconductor substrate; forming a silicon nitride-comprising layer over the first capacitor electrode material; generating an oxygen-comprising plasma remote from over the substrate comprising the silicon nitride-comprising layer, the oxygen-comprising plasma being generated at least in part from one of a) a mixture of O 2 and O 3 ; b) a mixture of O 2 and N 2 O; c) a mixture of O 3 and N 2 O; or d) a mixture of O 2 , O 3 and N 2 O; feeding the remote plasma-generated oxygen to the semiconductor substrate for no longer than 15 seconds at a substrate temperature of from 550° C. to 750° C. effective to form a silicon oxide-comprising layer over the silicon nitride-comprising layer; and after the feeding, forming second capacitor electrode material over the silicon oxide-comprising layer.
