The Semitool SSTF 221280 PB is a spray solvent tool (SST) designed for 6-inch wafers. The SSTF 221280 PB operates on 3-phase, 5-wire, 208 Vac power and was built in 1997.[1]
What it is
The Semitool SSTF 221280 PB Spay Solvent is a wet processing and cleaning tool. The Semitool SSTF 221280 PB is a spray solvent tool used for cleaning semiconductor wafers. The Semitool SSTF 221280 PB accommodates 6 inch wafers. The Semitool SSTF 221280 PB operates on 3 Phase - 5 Wire - 208 Vac power. The Semitool SSTF 221280 PB was built in 1997.[1][2]
How it works
General reference — not yet source-verifiedSpray solvent tools generally deliver liquid chemicals onto wafer surfaces in a controlled spray process. Wet cleaning systems of this class are designed to expose the wafer surface to cleaning media, carry away loosened contamination, and prepare the wafer for the next process step. Tool operation in this class commonly centers on chemical application, fluid handling, and post-clean wafer condition control.
Where it fits in the process flow
General reference — not yet source-verifiedWet processing and cleaning tools sit between patterning, deposition, etch, implant, or other wafer fabrication steps that leave residues or particles needing removal. A spray solvent tool is used when the process flow calls for solvent cleaning before a subsequent module that depends on a cleaner wafer surface. Such equipment supports line integration by reducing contamination carryover from one operation to the next.
Applications
The Semitool SSTF 221280 PB is used for cleaning semiconductor wafers.[2]
