PROCESS FOR THE EXPOSURE OF A RADIATION-SENSITIVE LAYER TO RONTGEN RAYS

摘要

Radiation sensitive layers are x-ray exposed by providing a metal mask pattern on the layer through which the layer is exposed. The metal mask pattern is formed by applying a blanket metal layer to the radiation sensitive layer followed by an electron beam sensitive resist layer which is patterned by an electron beam exposure process. The exposed portions of the metal layer are then etched away to form the metal mask pattern.
