Abstract:
Various embodiments include methods and integrated circuit structures. One method includes masking a structure with a mask to cover at least a portion of the structure under the mask, selectively implanting a material through a semiconductor layer and into a buried insulator layer forming an implant region. The implant region is substantially parallel to and below an upper surface of the structure. The method may also include masking an additional portion of the structure; etching a set of access ports though the semiconductor layer and partially through the insulator layer into the implant region; etching at least one tunnel below the upper surface of the structure in the implant region using the set of access; and depositing a conductor into the at least one tunnel and the set of access ports.
Abstract:
A first aspect of the disclosure provides for an integrated circuit structure. The integrated circuit structure may comprise a first metal structure in a first dielectric layer on a substrate in a crack stop area; and a first crack stop structure in a second dielectric layer, the first crack stop structure being over the first metal structure and including: a first metal fill contacting the first metal structure; and an air seam substantially separating the first metal fill and the second dielectric layer.
