Wet Cleaning line

Function

The Wet Cleaning line is a series of pre-made chemical baths employed for the wet chemical cleaning of silicon wafers after photoresist ashing. These baths are employed to reduce\remove the organics and the metal contaminations from silicon wafers, making them ready to be processed.

Chemical baths

HNO3 99%; HNO3 69%; HCl, H2O

Wafer Dimension

Only 4 inch wafers are allowed. Up to 25 wafers can be loaded for cleaning on one go.

Temperature Range

NA.

Contamination

Only non-Contaminated samples are allowed.

 

Restrictions

Two different chemical baths are prepared for processing with green metals and bare silicon wafers in order to reduce metal cross contamination.
