Patent ID: 7123348

Claim:
A device manufacturing method, comprising: (a) patterning a projection beam of radiation with an array of individually controllable elements; (b) projecting the patterned projection beam onto a target portion of a substrate, the projected patterned projection beam comprising a plurality of pixels; (c) controlling the elements such that each pixel in the plurality of pixels delivers a first radiation dose to the target portion that is below or equal to a predetermined dose; and (d) controlling the elements such that at least one selected pixel in the plurality of pixels delivers a second radiation dose greater than the predetermined dose to compensate at least partially for at least one of: (1) an effect of a defective element at a known position in the array of individually controllable elements on a pixel in the plurality of pixels adjacent the selected pixel, and (2) an underexposure of the target portion at a location corresponding to the selected pixel resulting from exposure of the location to a pixel in the plurality of pixels affected by a known defective element.
