Latest Patents

Watanabe holds a patent for a gas cluster ion beam apparatus and analyzing apparatus. This invention includes a sample chamber, a measurement apparatus, and a gas cluster ion beam apparatus. A cooling body is designed to separate the ionization chamber of the gas cluster ion beam apparatus from the nozzle support, preventing heat from the ionization filament from affecting the nozzle support. The temperature of the source gas emitted from the nozzle is maintained at a constant level by a gas heating device, ensuring a consistent sputtering rate. Additionally, a pressure controller keeps the source gas supplied to the nozzle at a constant pressure, allowing for precise control over the size of gas cluster ions. This innovation enables highly accurate depth surface profiling due to the constant sputtering rate.
