Wafer Quick Dump Rinser

Wet Processing Baths DR Series
The right way to rinse — requires less DI water and less DI water disposal.
Wet Processing Quick Dump Rinser
  • Natural polypropylene rinser tanks, DI manifold tubing, spray nozzles, and valves ensure compatibility with most process chemistries
  • Dual overhead spray manifolds with low misting nozzles eliminate over-spray
  • Knife-edge overflow weir enhances particulate removal
  • Large machined dump door accelerates dump time and eliminates particle build-up
  • Contoured vessel design reduces DI water consumption
  • Comes complete with retractable PVC cover
  • One-year warranty
The DR Series Wafer Quick Dump Rinser rinses silicon wafers and similar products free of acids, solvents, and other processing solutions. Because it uses less deionized (DI) water than other models, it saves on both DI water consumption and disposal expenses.

Water is sprayed from two sources to ensure optimal rinsing: from spray nozzles located above the wafer cassette and from spray jets and a nitrogen bubbler located below the cassette. The rinser is designed to prevent wasteful over-spray. To ensure product purity, all components are made of natural polypropylene or PVDF, with no exposed metal. A clear PVC cover retracts out of the way when not in use.

The DR Series uses a microprocessor controller to provide versatile, repeatable processing (order separately below). This controller allows up to 99 programmable cycles, far more than most batch operations require. Cycle time, start-cascade and dump time, and resistivity are options, or combinations of the three. Controller incorporates the pneumatics required to operate the DR Series module. The membrane keypad resists damage from most acids and solvents, and access coding enhances process security.

DR Series options include reclaim system; spray nozzles, DI water manifold, DI water valves or nitrogen valves made of Teflon; PVDF process tank; and process cover modifications.
