Overview

The DSS 200 Series II is a double-sided PVA scrubber that offers production-proven cleaning results for particles as small as 0.125µm. It can process wafers from 150mm to 200mm, with throughputs of 45-65 wafers per hour, making it a cost-effective wafer cleaning system. The system uses a simple brush scrubbing process to clean wafers, with both sides of the wafer being cleaned simultaneously and no edge exclusion. The unit features edge-only contact and an optional megasonic rinse sweep for effective cleaning results on metals and surface topography. A heat lamp assembly allows for fast dry cycles, with typical results showing a 200mm wafer can be dried in under 15 seconds using only an 1800 rpm spin cycle. At the end of the process, wafers are removed and placed in the output cassette by an edge gripping unload handler, with no contact of the wafer front or backside occurring from the spin module to the output cassette.
