- Large Substrate Wafer Wet Cleaning Systems
Large Substrate Cleaner (LSC) is a stand-alone cleaner which utilizes PC control for substrates up to 21" OD. A LabVIEW interface through a touch screen on the front panel provides greater control compared to the SWC systems and allows for controlled access levels such as operators, process engineers, and maintenance. The LSC incorporates the same, patented megasonic technology and chemical dispenses as the SWC systems. The combination of LabVIEW control and the larger process chamber support additional options such as ozonated DIW, high pressure DIW, pelliclized reticle, and piranha cleaning. Single wafer and cassette to cassette auto load/unload are available
