  • METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE AND A SEMICONDUCTOR DEVICE
    Publication number: 20240145581
    Abstract: In a method of manufacturing a semiconductor device, a fin structure having a channel region protruding from an isolation insulating layer disposed over a semiconductor substrate is formed, a cleaning operation is performed, and an epitaxial semiconductor layer is formed over the channel region. The cleaning operation and the forming the epitaxial semiconductor layer are performed in a same chamber without breaking vacuum.

  • Ion exchange resin tower and detection method of lifetime of resin therein
    Patent number: 7713420
    Abstract: An ion exchange resin tower including a tank, a supply line, an output line, and a plurality of sampling tubes is provided. The supply line guides a liquid into the tank, such that an ion exchange occurs between the liquid and the ion exchange resin in the tank. The processed liquid is guided out of the tank via the output line. The sampling tubes are disposed on a sidewall of the tank to sample the liquid flowing through the resin.
