Abstract:
Various embodiments of the present application are directed towards a method to integrate NVM devices with a logic or BCD device. In some embodiments, an isolation structure is formed in a semiconductor substrate. The isolation structure demarcates a memory region of the semiconductor substrate, and further demarcates a peripheral region of the semiconductor substrate. The peripheral region may, for example, correspond to BCD device or a logic device. A doped well is formed in the peripheral region. A dielectric seal layer is formed covering the memory and peripheral regions, and further covering the doped well. The dielectric seal layer is removed from the memory region, but not the peripheral region. A memory cell structure is formed on the memory region using a thermal oxidation process. The dielectric seal layer is removed from the peripheral region, and a peripheral device structure including a gate electrode is formed on the peripheral region.

Claim (Index 7):
The method according to  claim 6 , wherein the forming of the memory cell structure comprises:\n forming a memory gate dielectric layer, a memory gate electrode overlying the memory gate dielectric layer, and a memory gate hard mask overlying the memory gate electrode, wherein the memory gate dielectric layer is formed by the oxidation process.
