    摘要: A metal-ceramic multilayer structure is provided. The underlying layers of the metal/ceramic multilayer structure have sloped sidewalls such that cracking of the metal-ceramic multilayer structure may be reduced or eliminated. In an embodiment, a layer immediately underlying the metal-ceramic multilayer has sidewalls sloped less than 75 degrees. Subsequent layers underlying the layer immediately underlying the metal/ceramic layer have sidewalls sloped greater than 75 degrees. In this manner, less stress is applied to the overlying metal/ceramic layer, particularly in the corners, thereby reducing the cracking of the metal-ceramic multilayer. The metal/ceramic multilayer structure includes one or more alternating layers of a metal seed layer and a ceramic layer.

    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: One embodiment is a method of forming a circuit structure. The method comprises forming a first amorphous layer over a substrate; forming a first glue layer over and adjoining the first amorphous layer; forming a second amorphous layer over and adjoining the first glue layer; and forming a plurality of posts separated from each other by removing a first portion of the first amorphous layer and a first portion of the second amorphous layer. At least some of the plurality of posts each comprises a second portion of the first amorphous layer, a first portion of the first glue layer, and a second portion of the second amorphous layer.
