Abstract

A method of fabricating a non-volatile memory embedded logic circuit having a low voltage logic gate oxide layer and tunnel oxide layer is described. Both the low voltage logic gate oxide and the tunnel oxide layers are formed in a single step, thereby reducing the number of overall processing steps needed to form the devices.
