Abstract
An apron and a skirt of a spatial light modulator are each coupled to a substrate by reverse-bias diodes. The spatial light modulator includes liquid crystal material between an array of electrodes and a ground electrode. The apron surrounds the array, and the segmented skirt surrounds the apron. The array, apron, and skirt are formed over the substrate. The reverse-bias diodes provide suitable electrical isolation during normal operation, but dissipate excessive charge that might accumulate during plasma etching as the modulator is being manufactured and that might otherwise induce damage due to electrostatic discharge.
