  • Method for integrating SONOS non-volatile memory into a standard CMOS foundry process flow
    Patent number: 8258027
    Abstract: An embodiment of a method is disclosed to integrate silicon oxide nitride oxide silicon (SONOS) non-volatile memory (NVM) into a conventional complementary metal oxide semiconductor (CMOS) semiconductor foundry process flow. An embodiment of the method only adds a few additional steps to a standard CMOS foundry process flow and makes minor changes to the rest of the baseline CMOS foundry process flow to form a new process module that includes both CMOS devices and an embedded SONOS NVM.

  • Radiation hardened multi-bit sonos non-volatile memory
    Publication number: 20090059675
    Abstract: In one aspect, a radiation hardened transistor includes a buried source, buried drain and a poly-silicon gate separated from the buried source and the buried drain by a buried oxide. A recessed P+ implant or a blanket P+ implant is disposed in a substrate. A portion of the recessed P+ implant or a portion of the blanket P+ implant is disposed beneath outer edges of the poly-silicon gate, in a channel separating the buried source and the buried drain.
