Latest Patents

One of Chen's latest patents is a method for manufacturing a phase change memory device with a pillar bottom electrode. This innovative method involves creating a mushroom-cell type phase change memory by manufacturing a pillar of bottom electrode material on a substrate that includes an array of conductive contacts in electrical communication with access circuitry. The process includes depositing a layer of electrode material to ensure reliable electrical contact with the conductive contacts, followed by etching the electrode material to form a pattern of electrode pillars. A dielectric material is then deposited and planarized to expose the top surfaces of the electrode pillars. Finally, a layer of programmable resistive material, such as a chalcogenide, is deposited, along with a top electrode material, resulting in a device featuring bottom electrode pillars with larger bottom surfaces than top surfaces.

Another notable patent is the chalcogenide layer etching method. In this process, a protective layer is deposited on a chalcogenide layer, and a patterned photoresist layer is formed on top. Both layers are etched to create openings to the chalcogenide layer, followed by the removal of the etched photoresist layer, leaving portions of the etched protective layer. The chalcogenide layer is then etched through the openings in the protective layer, showcasing Chen's innovative approach to memory technology.
