Abstract
The processes of trap generation and electron trapping in the tunnel oxide of SuperFlash memory cells have been analyzed. The strongly non-uniform distribution of electric field in the SuperFlash cell allowed us to rule out the electron- or hole-related mechanisms of trap generation. The experimental results of single-trap-induced modulation of the tunneling rate, and the analysis of field and potential distribution in the tunnel oxide, point to the high electric field as a direct cause of electron-trap generation.
