In this paper we analyze selective alternating PSM synthesis and OPC modeling parameters, taking into account lithographic constraints to PSM conformance. The results shown include phase and trim regions size and shape impact on the images printed on wafers at optimum conditions and through focus, at ideal as well as in the presence of errors in phase and transmission due to mask manufacturing.
