Latest Patents

One of Nakagawa's latest patents is for a ceramic heater and method for producing the same. This invention features an electrostatic chuck that includes a disc-shaped alumina ceramic base, with a heater electrode and an electrostatic electrode embedded within it. The upper surface of the alumina ceramic base serves as a wafer-receiving surface. The heater electrode is designed in a pattern shape, allowing it to cover the entire surface of the alumina ceramic base. When voltage is applied, the heater electrode generates heat to warm the wafer. Notably, this heater electrode contains TiSi as a main component.

Another significant patent is for a method for producing a powder molded product and the product itself. This method involves molding a slurry that contains a powdery molding raw material, a dispersion medium, a dispersant, a binder precursor, a reaction promoter, and a pseudo-plasticity-imparting agent. The process includes a slurry preparation step, a molding step to create a primary molded product, and a drying-solidification step that solidifies the slurry by promoting a chemical reaction and removing the dispersion medium through evaporation.
