Description

A laser-assisted photochemically driven etching process has been developed for Hg/sub 0.8/Cd/sub 0.2/Te (12 μm material). It is an etch which does not melt the surface of the material or induce mercury migration. Small geometry features (vias less than 10 μm in diameter) with straight-edged sidewalls have been produced. The etching mechanism is a photoenhanced rapid oxidation with subsequent solvation of the oxides
