Sacrificial surfactanated pre-wet for defect reduction in a semiconductor photolithography developing process
Abstract:
A method and apparatus for developing a resist on a substrate in which a sacrificial surfactant-containing liquid is first applied to a resist as a pretreatment to reduce developing process defects and to improve the development process time and the uniformity of the resist. The pretreatment is followed by supplying a developing solution to the resist and thereafter developing the resist.
