Latest Patents
One of his latest patents involves semiconductor devices and methods of fabricating the same. This patent describes a semiconductor device that includes lower wires, upper wires crossing the lower wires, select elements at the intersections, and memory elements positioned between the select elements and the upper wires. Notably, each memory element features a lower electrode with a top width greater than its bottom width, along with a data storage layer comprising multiple magnetic layers stacked on the lower electrode's top surface, which has a rounded edge.
Another significant patent pertains to the manufacturing of magnetoresistive random access memory (MRAM) devices. In this method, a lower electrode is formed on a substrate, followed by the sequential formation of a first magnetic layer, a tunnel barrier layer, and a second magnetic layer. An etching mask is then applied to the second magnetic layer, and an ion beam etching process is executed, utilizing both a first and a second ion beam. This process results in a magnetic tunnel junction (MTJ) structure that is free of by-products after etching.
