Latest Patents

Among his latest innovations, Yanagi has developed a Plasma processing method and apparatus that showcases remarkable characteristics. This technology effectively reduces the amount of electric charge on a plasma-processed substrate while preventing plasma damage and dielectric breakdown. Before plasma processing, both the top and bottom surfaces of the substrate are subjected to a weak plasma composed mostly of inert gas. This technique neutralizes charges on the substrate, utilizing gases such as argon (Ar), helium (He), nitrogen (N), hydrogen (H), and vaporized water (HO), either separately or in a mixed gas form.

Additionally, his Dry etching method has improved the precision of substrate processing. In this method, the etching process of a multi-layer film substrate is closely monitored by identifying the layer being processed. During the etching of the lowermost layer until completion, CHF gas is introduced into the processing gas, enhancing the etching accuracy and efficiency.
