What it is

The Ontrak DSS 200 Post is a post-CMP wafer cleaner in the OnTrak DSS 200 family. The tool is a double-sided PVA scrubber for semiconductor wafer cleaning.[1][9][3]

How it works

The Ontrak DSS 200 Post uses double-sided PVA scrubbing with dual brush boxes. The tool also includes ammonia dispense, IR-assisted spin drying, robotic unload, and vertical unload handling.[1][2][3]

Applications

The Ontrak DSS 200 Post is used for post-CMP cleaning of oxide, polysilicon, nitride, tungsten, aluminum, and copper. The tool is also used for general-purpose cleaning, including post-CVD oxides, post-metallization surfaces, surface topography, and trench cleaning.[1][2][3]
