Design, fabrication and characterization of high density radiation hardened SONOS/CMOS EEPROMs for space and military systems

We present the design, fabrication and characterization of a radiation-hardened, SONOS/CMOS 1 Mb EEPROM for space and military systems. An advanced 0.35micron, 4-level tungsten plug, CMP, high-density interconnect SONOS/CMOS technology will be described for 16 Mb SONOS/CMOS EEPROMs. SONOS/CMOS radiation-hardened EEPROMs are flight-qualified and currently employed in advanced space-borne and military systems.
