Latest Patents

Parker holds a patent for a "Method for interconnecting magnetoresistive memory bits." This process involves forming electrical interconnects between memory bits in a magnetoresistive memory device. The method begins with the formation of an initial dielectric layer over a semiconductor substrate. A magnetoresistive storage layer is then created over this dielectric layer. An electrically conductive stop layer, which is selective to etch processes and mechanically hard, is deposited over the storage layer. Following this, a hardmask layer is formed and etched to expose the stop layer. The stop layer and the magnetoresistive storage layer are etched using ion milling until the initial dielectric layer is exposed, defining individual memory bits. An isolation layer is formed over the hardmask layer and in the etch regions between the bits. This layer is then planarized using chemical mechanical polish (CMP) until the stop layer is exposed. Finally, an interconnect layer is formed over the exposed regions of the stop layer and is etched to create electrical interconnects between the memory bits.
