Abstract

A method for fabricating a SONOS memory is disclosed. First, a semiconductor substrate is provided and a SONOS memory cell is formed on said semiconductor substrate. A passivation layer is deposited on the SONOS memory cell and a contact pad is formed on the passivation layer. Subsequently, an ultraviolet treatment is performed and an annealing process is conducted thereafter.
