Abstract:
1. A method of fabricating a micromirror in a double substrate spatial light modulator comprising: etching trenches into a first glass substrate; forming a first spacer material layer overlying said first glass substrate and filling said trenches; depositing a metal layer overlying said first spacer material layer and patterning said metal layer to form a mirror; forming a second spacer material layer overlying said mirror; forming mirror support posts through openings in said first and second spacer material layers and contacting said first glass substrate between said trenches; forming a hinge through an opening in said second spacer material layer to said mirror; removing said first and second spacer material layers wherein said mirror can tilt on said hinge upward from said first glass substrate and downward into said trench in said first glass substrate; and forming a second glass substrate overlying said mirror.
