Abstract

Erasing gate current in various flash EEPROM structures has been characterized. The charge transport of gate current is composed of Fowler-Nordheim electron tunneling and/or band-to-band tunneling induced hot hole injection. Both of the mechanisms are analyzed in a two-dimensional simulation. Good agreement between experiment and simulation is obtained. The hot hole injection is found to be a dominant erasing mechanism in certain device structures.
