Metallic standoff for an electro-optical device formed from a fourth or higher metal interconnection layer

An electro-optical device may be defined using metallic standoffs between a top plate and a substrate, such as a silicon substrate in a liquid crystal on silicon (LCOS) technology. In one embodiment, the metallic standoffs may be formed from a metal layer, such as metal four layer, above the metal l...

Zusammenfassung:An electro-optical device may be defined using metallic standoffs between a top plate and a substrate, such as a silicon substrate in a liquid crystal on silicon (LCOS) technology. In one embodiment, the metallic standoffs may be formed from a metal layer, such as metal four layer, above the metal layer used to form the metal pixel mirrors. In this way, relatively constant and uniform cell thicknesses may be achieved without significantly increasing the processing overhead.
