What it is

The Semitool 870 S is a dual stack spin rinse dryer. The Semitool 870 S is categorized for wet processing and clean applications. The Semitool 870 S operates on 1 Phase, 3 Wire, 220 Vac, 50/60 Hz.[1][2][7]

How it works

General reference — not yet source-verified

A spin rinse dryer holds substrates in a rotor or carrier inside a process chamber. A spin rinse dryer dispenses rinse fluid during rotation to wash off residues from earlier wet steps. A spin rinse dryer then continues rotation to shed liquid and complete drying.

Where it fits in the process flow

General reference — not yet source-verified

A spin rinse dryer is typically placed after wet benches, etch tanks, strip baths, or chemical clean modules. A spin rinse dryer prepares substrates for inspection, metrology, coating, bonding, or other downstream steps that require a clean and dry surface.

Applications

The Semitool 870 S is used in semiconductor manufacturing wet processing and clean applications.[7][3]
