  • Spatial light modulator with buried passive charge storage cell array
    Patent number: 5671083
    Abstract: A monolithic DMD spatial light modulator (20) including a storage cell array (24) of charge storage elements (30). Each charge storage cell (30) is formed using robust MOS processes, and comprises a pair of capacitors (32) having a polysilicon electrode fabricated over a substrate, and separated by a thin oxide dielectric. Each capacitor (32) is shielded by several light impermeable metal shields (37, 64, 66, 68, 72, 74, 80, 82, 88) to prevent discharging due to light incident to SLM (20). The substrate electrode (38) is encompassed by an n+ doped region (42) providing a source of minority carriers to an inversion region under the polysilicon electrode (50).
