Abstract

A method of manufacturing an ONO (oxide-nitride-oxide) insulating layer for a flash memory device, the insulating layer including a first oxide layer, a nitride layer over the first oxide layer, and a second oxide layer over the nitride layer, wherein at least one of the first oxide layer, the nitride layer and the second oxide layer are conditioned using laser thermal annealing.
