Latest Patents

Nagaoka holds a patent for a "Method of manufacturing semiconductor device, and semiconductor device." This patent outlines a detailed process that includes several steps. First, a gate electrode is formed over a silicon substrate, with a gate insulation film in between. Next, etching with the gate electrode as a mask is conducted to dig down a surface layer of the silicon substrate. Subsequently, a first layer including an SiGe layer is epitaxially grown on the dug-down surface of the silicon substrate. Following this, a second layer, which includes an SiGe layer lower in Ge concentration or an Si layer, is formed on the first layer. Finally, at least the surface side of the second layer is silicided to form a silicide layer. Nagaoka's innovative approach has led to advancements in semiconductor technology.
