Latest Patents

Fukushima holds a patent for a wafer back surface cleaning device. This device is designed to prevent foreign matter from re-adhering to a wafer during and after the cleaning process. The device features a hand that receives a cleaned wafer at a designated cleaning position and conveys it to subsequent processing stages. Another hand conveys the wafer before grinding to the cleaning position and transfers the cleaned wafer with its front surface directed upward. The cleaning pad and cleaning water supply nozzle work together to discharge cleaning water onto the back surface of the wafer. At the cleaning position, the hand brings the back surface of the wafer into contact with the cleaning pad for scrubbing. After scrubbing, the device rinses the back surface of the wafer and transfers it to the next stage.
