Abstract
A preferred embodiment of the invention provides a method for forming an integrated circuit. The method comprises forming a resist layer on a substrate. Preferably, the photoresist layer comprises a photo acid generator (PAG). Embodiments include irradiating the resist through a mask to generate a photoacid in the resist, heating the resist at a first temperature, and then heating the resist at a second temperature. Heating at the first temperature evaporates water from the resist. Heating at the second temperature deprotects the resist.
