Masayoshi Tagami is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on innovative methods for enhancing semiconductor device fabrication.

Latest Patents

One of his latest patents is a "Patterning process method for semiconductor devices." This method involves forming a semiconductor device that includes a SiARC layer over a photoresist film, which is placed over spacer portions on a spacer assist layer above a hard mask layer. The SiARC layer is designed to have an etch rate similar to that of the spacer assist layer. The process includes removing the photoresist and SiARC layers from a specific region to expose the spacer portions and the spacer assist layer. The remaining layers are then etched to create hard mask portions in the first region using the remaining spacer portions as an etching mask. Another notable patent is the "Method for forming a dual damascene interconnect structure." This improved method involves creating an interconnect layer using a multilayer hard mask that includes both metal and dielectric masks. The process ensures that the second opening pattern aligns with the first pattern, enhancing the efficiency of semiconductor device fabrication.
