Introduction
Roger Yen is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on advanced methods for fabricating interconnects and enhancing the performance of DRAM cells.
Latest Patents
Roger Yen's latest patents include a method of fabricating an interconnect of a capacitor. This method involves providing a substrate with a capacitor that includes a bottom electrode, a dielectric layer, and a top electrode. A spin-on dielectric layer is formed on the substrate, which is thicker on the substrate than on the top electrode. The layer is then etched back to expose the top electrode, followed by the formation of a patterned metal layer in direct contact with the top surface of the top electrode. Another significant patent is for a DRAM cell with a roughened poly-Si electrode. This involves creating a porous silicon layer through wet etching of a polysilicon layer, followed by treatment with a specific solution to form a roughened polysilicon layer. The process continues with the deposition of a dielectric film and a conductive layer, which are then etched into a portion of the layer.
