Abstract
The present disclosure relates to a method of embedding an ESF3 memory in a HKMG integrated circuit that utilizes a replacement gate technology. The ESF3 memory is formed over a recessed substrate which prevents damage of the memory control gates during the CMP process performed on the ILD layer. An asymmetric isolation zone is also formed in the transition region between the memory cell and the periphery circuit boundary.
