Abstract:
A method for repairing at least one bump or divot defect in an integrated circuit processing phase shift template having phase shift areas and non-phase shift areas, the method comprising the steps of:locating the at least one defect in said phase shift template;coating the phase shift template with resist;exposing the resist in an area corresponding to the at least one defect and areas adjacent to the at least one defect without exposing other areas;developing the resist so as to uncover the area corresponding to the at least one defect and areas adjacent to the at least one defect;subsequently, depositing repair material in the areas uncovered in the developing step, such that the repair material covers the at least one defect; andsubsequently, removing the repair material and material of the at least one defect to a level approximately equal to a non-defect level of a substrate in the areas adjacent to the defect.
