Title: Kentaro Sera: Innovator in Multilevel Interconnect Structures
Introduction
Kentaro Sera is a prominent inventor based in Yokkaichi, Japan. He has made significant contributions to the field of multilevel interconnect structures, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of electrical connections in advanced technologies.
Latest Patents
Kentaro Sera's latest patents include innovative methods for creating multiheight contacts via structures for multilevel interconnects. One of his patents describes a process where contact openings extending to sacrificial layers at different depths can be formed. This is achieved by sequentially exposing a greater number of openings in a mask layer through iterative alternation of trimming a slimming layer over the mask layer and performing an anisotropic etch. This method allows for the simultaneous formation of pairs of electrically conductive via contacts and electrodes as integrated line and via structures. Another embodiment of his patent involves the creation of encapsulated unfilled cavities in contact openings through non-conformal deposition of a material layer. This process also includes the replacement of portions of the sacrificial layers to form electrically conductive electrodes, followed by the formation of electrically conductive via contacts on these electrodes. The resulting electrically conductive via contacts can be provided with a self-aligned insulating liner, enhancing their performance.
