Method of forming a resist mask resistant to plasma etching

Patent ·
OSTI ID:5272811

A mask which is resistant to a plasma etching treatment is formed by lithographically patterning a radiation sensitive film present on a substrate. The etch resistance of the mask is enhanced by exposure to a carbon monoxide plasma which forms a region with an enhanced etch resistance over the surface of the patterned film. This method may be used, for example, to manufacture a photomask using a chromium coated glass substrate, or during the manufacture of semiconductor devices on a semiconductor wafer substrate.
