Patent ID: 7936406

Claim:
An LCOS device comprising: a semiconductor substrate; a transistor formed within the semiconductor substrate, the transistor having a first node, a second node, and a row node; a first capacitor structure coupled to the transistor, the first capacitor structure comprising: a first polysilicon layer coupled to the second node of the transistor; a first capacitor insulating layer overlying the first polysilicon layer; a second polysilicon layer overlying the insulating layer, the second polysilicon layer being coupled to a reference potential; a second capacitor structure coupled to the transistor, the second capacitor structure comprising: a first metal layer coupled to the reference potential; a second capacitor insulating layer; a second metal layer coupled to the second node of the transistor; a pixel electrode comprising the first metal layer, the pixel electrode being coupled to the second node of the transistor; a mirror surface on the pixel electrode; and a light shielding layer formed from a portion of the second metal layer.
