Abstract
The invention involves a new sensitizing bath for chalcogenide glass-based resists. The inventive bath is alkaline and contains a silver complex whose ligand includes hydrophobic and hydrophilic moieties. Upon immersing a chalcogenide glass in the bath, a silver composition-containing film is formed on the surface of the glass. This film is substantially free of pin holes and has a uniform thickness which is insensitive to immersion time and largely determined by the pH of the bath.
