Claim One:
1. A method for providing a plurality of microelectric devices on a plurality of fields on a substrate, each of the plurality of fields including at least one microelectric device including a critical device feature and at least one remaining device feature distal from the critical device feature, the method comprising: providing a layer of photoresist on the plurality of fields, the layer of photoresist for fabricating the plurality of microelectric devices; exposing the layer of photoresist using a dark field mask, the dark field mask for defining a critical mask feature corresponding to the critical device feature and exposing a first portion of the plurality of fields, the first portion including not more than five percent of each of the plurality of fields, at least part of the at least one critical device feature being oriented at an angle other than ninety degrees from the at least one remaining device feature; and exposing the layer of photoresist using a clear field mask, the clear field mask for defining at least one remaining mask feature corresponding to the at least one remaining device feature, the clear field mask exposing a second portion of the plurality of fields, the second portion being different from the first portion.
