Latest Patents

Motohara holds a patent for an "Optical filtering device, defect inspection method and apparatus therefor." This invention involves an optical filtering device designed to detect defects with high sensitivity. The device includes a shutter array formed on an optically opaque thin film produced on a silicon-on-insulator (SOI) wafer. The SOI wafer is partially removed beneath the shutter patterns to create perforation portions. Working electrodes are formed on the remaining parts of the SOI wafer, while a glass substrate with electrode patterns supports the shutter array. The power supply section provides electric power to the electrodes, allowing the shutter patterns to open and close in relation to the perforation portions, thus enabling optical filtering.
