Abstract:
1. A method for photo-processing photo-imageable material, comprising: providing a semiconductor substrate having a photo-imageable material thereover; determining locations of the photo-imageable material where flare hot spots are expected to occur, such locations being defined as hot spot locations and the remainder of the photo-imageable material being defined as a non-flare location; exposing the photo-imageable material to a pattern of first actinic energy to form a primary pattern within the photo-imageable material, and to form flare hot spots in the hot spot locations; exposing the photo-imageable material to a compensating dose of second actinic energy that is provided in addition to the first actinic energy; the compensating dose being a substantially uniform dose directed into at least the majority of the non-flare location and not directed into the hot spot locations; wherein the exposing the photo-imageable material to the pattern of first actinic energy comprises passing the first actinic energy through a first radiation-patterning tool to form the primary pattern and flare hot spots; and wherein the exposing the photo-imageable material to the compensating dose of second actinic energy comprises passing the second actinic energy through a second radiation-patterning tool; with said second radiation-patterning tool being a different radiation-patterning tool than the first radiation-patterning tool.
