A liquid crystal on silicon display device (LCOS) has a semiconductor substrate comprising a surface region and a gate dielectric layer overlying the surface region. The device also has a word line formed overlying the gate dielectric layer and a first source/drain region coupled to the word line. The device has a bottom electrode structure formed overlying an interlayer dielectric. A capacitor dielectric is formed overlying the bottom electrode. A top electrode structure is formed overlying the capacitor dielectric to form a capacitor structure including the bottom electrode structure, the capacitor dielectric, and the top electrode structure. The device has a mirror surface formed overlying the top electrode structure to form a pixel electrode structure and a liquid crystal material provided overlying the mirror surface. In an embodiment, the LCOS described above is in an integrated circuit chip that also includes a DRAM device.
