Abstract:
A method of controlling the thickness of gate oxides in an integrated CMOS process which includes performing a two-step gate oxidation process to concurrently oxidize and therefore consume at least a first portion of the cap layer of the NV gate stack to form a blocking oxide and form a gate oxide of at least one metal-oxide-semiconductor (MOS) transistor in the second region, wherein the gate oxide of the at least one MOS transistor is formed during both a first oxidation step and a second oxidation step of the gate oxidation process.

Claim (Index 30):
A method, comprising:\n forming a dielectric stack including a charge-trapping layer on a substrate; patterning the dielectric stack to form a gate stack of a non-volatile memory (NVM) transistor in a first region of the substrate while concurrently removing the dielectric stack in a second region of the substrate; performing an oxidation process to oxidize at least a portion of the dielectric stack to form a blocking oxide on the charge-trapping layer while concurrently forming a gate oxide of at least one metal-oxide-semiconductor (MOS) transistor in the second region; and forming a nitride structure disposed over the gate stack, wherein the nitride structure changes energy levels of charge traps configured to be formed in the charge-trapping layer to increase charge retention of the charge-trapping layer.
