  • Patent number: 11031409
    Abstract: Various embodiments of the present application are directed to an embedded memory boundary structure with a boundary sidewall spacer, and associated forming methods. In some embodiments, an isolation structure is disposed in a semiconductor substrate to separate a memory region from a logic region. A memory cell structure is disposed on the memory region and a cell boundary structure is formed on the isolation structure including a boundary sidewall spacer. A protecting dielectric layer is disposed on a top surface of the boundary sidewall spacer. The boundary sidewall spacer and the protecting dielectric layer provide a smooth boundary sidewall that is not subject to damage during formation of the logic device structure and, hence, is not subject to trapping high ? etch residue during formation of the logic device structure with HKMG technology.
