Latest Patents

One of Yi-Tsung Tsai's latest patents is a memory device and method of forming the same. This invention includes a memory device comprising a plurality of stack structures disposed on a substrate, along with a dielectric layer. Each stack structure features a first conductive layer, a second conductive layer, an inter-gate dielectric layer, a metal silicide layer, and a barrier layer. The second conductive layer is positioned on the first conductive layer, while the inter-gate dielectric layer is situated between the two conductive layers. The metal silicide layer is placed on the second conductive layer, and the barrier layer is located between the metal silicide layer and the second conductive layer. The dielectric layer surrounds the lower portion of the stack structures, exposing part of the metal silicide layer.

Another notable patent involves methods for forming memory devices. This method includes the formation of a plurality of gate structures on a substrate, the creation of a first spacer on opposite sides of the gate structures, and the filling of a dielectric layer between adjacent first spacers. Additionally, a metal silicide layer is formed on the gate structures, followed by the conformal formation of a spacer material layer over the metal silicide layer, the first spacer layer, and the dielectric layer. An etch back process is then performed on the spacer material layer to create a second spacer on opposite sides of the metal silicide layer.
