AbstractA Method For Reducing Lens Aberrations Sensitivity And Proximity Effects Of Alternating Phase Shifted Masks Is Described. The Critical Features Of A Chip Design Layout Are First Identified. Multiple, Narrow Phase Regions And Auxiliary Phase Transitions, Which Provide Additional Opaque Features, Are Then Formed Alongside The Critical Features Such That A Grating Pattern Of Substantially Uniform Pitch Is Printed. Together With A Complementary Trim Mask, The Circuit Pattern So Delineated Has Reduced Sensitivity To Lens Aberrations And Proximity Effects.
