Latest Patents

Nancy Han holds a patent titled "Method and structure for top metal formation of liquid crystal on silicon devices." This invention provides an LCOS device with improved bonding pad features. The device includes a substrate, a transistor layer overlying the substrate, and an interlayer dielectric layer overlying the transistor layer. A first conductive layer is situated over the interlayer dielectric layer, with a second interlayer dielectric layer above it. An enlarged opening for a bonding pad structure is present in a first portion of the second interlayer dielectric layer. A barrier metal layer is formed within this enlarged opening, creating a liner that covers exposed regions. A metal material fills the enlarged opening, and a thickness of aluminum material is overlaid on the metal material. The bonding pad structure is formed from a portion of the aluminum material and is coupled to the metal material in the enlarged opening. Nancy holds 1 patent.
