Abstract
An improved fabrication process employing relatively non-critical masks permits the fabrication of high density electrically programmable and erasable EEPROM or FLASH-EPROM devices. In practice the novel process permits the fabrication of a contactless, cross-point array providing for a more comfortable 'pitch' of bitline metal-definition while realizing a cell layout with a gate structure which extends laterally over adjacent portions of field oxide, thus establishing an appropriate capacitive coupling between control and floating gates. Two alternative embodiments are described.
