Latest Patents
One of Nakayama's latest patents is an X-ray source and X-ray lithography method. This invention features a gas injection type plasma X-ray source that includes a gas plenum for storing a discharging gas at pressures ranging from 150 Torr to 1000 Torr. The stored gas is injected between a pair of electrodes through a gas valve, forming a gas jet that produces plasma. A voltage is applied between the electrodes to generate discharge plasma, resulting in the emission of X-rays from the linear plasma. This X-ray source boasts high conversion efficiency, improved stability, and increased X-ray output.
Another notable patent is a chemical vapor deposition apparatus. This apparatus consists of a reactor divided into a reaction space and a purging space, with a susceptor that supports a wafer. The design allows for effective pressure reduction in both the reactor and loading chamber. The susceptor features multiple recesses for wafer handling, and it is heated by a lamp unit positioned outside a transparent wall. This compact apparatus processes one or a small number of wafers at a time, ensuring high reproducibility and a uniform film deposition.
