Abstract

See full text

A negative resist pattern is formed using a resist containing a diazoquinone sensitizer. An imagewise exposed area of a layer of the resist is subjected to heat treatment with a water-containing heating medium in the presence of a carboxyl-inactivating agent. The entire surface of the layer is exposed to radiation. The thus-exposed surface is then treated with an alkaline developer solution. An apparatus suitable for use in the practice of the above process is also disclosed.
