    • A process for forming high resolution resist patterns using a positive type resist material comprising a photoactive resin having phenolic hydroxyl groups, an organic solvent, and 5 to 50% by weight of trimethylsilylnitride.The process for forming high resolution mask patterns comprises the steps of forming a first resist layer on a wafer for planarizing the wafer surface, forming a second resist layer on said first resist layer by using the positive type resist material mentioned above wherein the first resist layer has a higher plasma etch rate than the second resist layer, exposing and removing the second resist layer so as to form a mask pattern, and subjecting the mask pattern and the first resist layer to a reactive ion etching so as to removce the first resist layer by using the mask pattern as an etching mask.

    • A positive type resist material with high oxygen plasma resistance and a process for forming high resolution resist patterns using the resist material are disclosed. The positive type resist material comprises a photoactive resin, an organic solvent, and 5 to 50% by weight of trimethylsilylnitrile.A compound of a phenol resin having phenolic hydroxyl groups and a photoactive compound, or phenolformaldehyde is used as an example of the photoactive resin. As the solvent, selected from the group consisting of 1,2-ethoxyl acetate, methyl ethyl ketone, xylene, and n-butyl acetate are used alone or in combination. The process for forming high resolution resist patterns comprises steps of forming a first resist layer for planarizing a wafer surface, forming a second resist layer on the first resist layer by using the above mentioned positive type resist material, forming patterns on the second resist layer by exposing the second resist layer to the exposure energy and developing, and transferring the patterns on the second resist layer to the first resist layer and the wafer by reactive ion etching using the second resist layer as an etching mask.
