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 35):
A method comprising:\n forming a dielectric stack on a substrate, the dielectric stack including a tunneling dielectric overlying the substrate and a charge-trapping layer overlying the tunneling dielectric; patterning the dielectric stack to form a non-volatile (NV) gate stack of a non-volatile memory (NVM) transistor in a first region of the substrate and to remove the dielectric stack from a second region of the substrate; and performing a two-step oxidation process to concurrently oxidize at least a first portion of the dielectric stack 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 during a first oxidation step of the oxidation process, the dielectric stack of the NV gate stack remains substantially unchanged, both stoichiometrically and chemically.
