Latest Patents

The supplied information identifies one patent for Cumpian: “Method for Forming a Cavity Capable of Accessing Deep Fuse Structures and Device Containing the Same.” The method uses a staged etching process. First, a mask is formed over a structure such as a poly fuse, and an etch is made partway through a first dielectric layer. A second dielectric layer is then deposited, and another mask is used to complete the etch toward the structure. The resulting cavity retains unetched second dielectric material along its sidewalls. This approach is designed to provide access to a deep fuse structure while controlling the cavity’s formation.
