    摘要: A method of forming of MEMS nanostructures includes a portion of a substrate is recessed to form a plurality of mesas in the substrate. Each of the plurality of mesas has a top surface and a sidewall surface. A light reflecting layer is deposited over the substrate thereby covering the top surface and the sidewall surface of each mesa. A protection layer is formed over the light reflecting layer. An ARC layer is formed over the protection layer. An opening in a photo resist layer is formed over the ARC layer over each mesa. A portion of the ARC layer, the protection layer and the light reflecting layer are removed through the opening to expose the top surface of each mesa. The photo resist layer and the ARC layer over the top surface of each mesa are removed.

    摘要: An integrated circuit structure includes a substrate having a top surface; a first conductive layer over and contacting the top surface of the substrate; a dielectric layer over and contacting the first conductive layer, wherein the dielectric layer includes an opening exposing a portion of the first conductive layer; and a proof-mass in the opening and including a second conductive layer at a bottom of the proof-mass. The second conductive layer is spaced apart from the portion of the first conductive layer by an air space. Springs anchor the proof-mass to portions of the dielectric layer encircling the opening. The springs are configured to allow the proof-mass to make three-dimensional movements.
