Semicon Wafer Surface Inspection system WM-10

More sensitivity and Eco-friendly Ever seen under 90nm process node

WM-10 is high-end surface inspection system of our WM Series. This product can detect any type of micro defects on non-patterned wafer of semiconductor device and avilable for wide-range wafer size from 6-inch to 8-inch or from 8-inch to 12-inch. And this product is equipped with bule-violet semiconductor laser which is the world's first wafer surface analyzer in this field. This laser makes a contribution to reduce the running cost. This prduct is eco-friendly, as well as being of high quality high speed measuring and low-priced.
