● High-quality device to perform bulk etching silicon wafers surfaces with O3 and HF.
● No droplets generate on wafer surface because of etching with gas.
● Uniformity / Flatness of wafers after etching process is within 10%.
● Contaminants generated during etching process do not move to other places.
● Bulk etching is performed on the entire surface with wafers, but partial evaluation is also possible by mapping
collecting.
● Wafers are handled manually, however the equipment is controlled on PC, it is easy to operate.
