ABSTRACT:
A method of selectively altering material properties of a substrate in one region while making a different alteration of material properties in an adjoining region is provided. The method includes selectively masking a first portion of the substrate during a first exposure and selectively masking a second portion of the substrate during a second exposure. Additionally, a mask may be formed having more than one thickness where each thickness will selectively reduce the amount of energy from a blanket exposure of the substrate thereby allowing a substrate to receive different levels of energy dosage in a single blanket exposure.
