    摘要: A method of forming an integrated circuit structure includes forming an opening in a substrate, with the opening extending from a top surface of the substrate into the substrate. The opening is filled with a filling material until a top surface of the filling material is substantially level with the top surface of the substrate. A device is formed over the top surface of the substrate, wherein the device includes a storage opening adjoining the filling material. A backside of the substrate is grinded until the filling material is exposed. The filling material is removed from the channel until the storage opening of the device is exposed.

    摘要: The present disclosure provides various methods for removing an anti-stiction layer. An exemplary method includes forming an anti-stiction layer over a substrate, including over a first substrate region of a first material and a second substrate region of a second material, wherein the second material is different than the first material; and selectively removing the anti-stiction layer from the second substrate region of the second material without using a mask.
