NIST CNST Nanofab Equipment
Wet Chemistry

Certain commercial equipment, and software, are identified in this documentation to describe the subject adequately. Such identification does not imply recommendation or endorsement by the NIST, nor does it imply that the equipment identified is necessarily the best available for the purpose.


Heated Wet Chemical Bench: 6-ft

This tool is used for the "RCA" cleaning of wafers to remove organic and metallic surface contaminants. It is located in an ultra-clean CMOS-compatible area and is subject to strict restrictions to prevent cross contamination.

  • 72" Open Wet Bench.
  • Manufacturer: Reynolds Tech, East Syracuse, NY, ph: 315-437-0532
  • Contains 2 dip tanks, two reflux quartz heated baths, glove rinse, DI and N2 spray guns, GFCI 120 VAC receptacle, and two safety eyewash stations.
  • Capable of handling small samples up to a full cassette of 6" wafers.
  • Tank 1: Dip tank with lid (Buffered Oxide Etch-BOE)
  • Tank 2: Reflux heated bath (RCA Standard Clean 1-SC1)
  • Tank 3: Dip Tank with lid (2 % HF)
  • Tank 4: Dump Rinse with lid
  • Tank 5: Reflux heated bath (RCA Standard Clean 2-SC2)
 6 ft Heated Wet Chemical Bench

  • Capable of handling small samples up to a full cassette of 6" wafers.
  • Tank 1: Dip tank with lid (Buffered Oxide Etch-BOE).
  • Tank 2: Reflux heated bath (RCA Standard Clean 1-SC1).
  • Tank 3: Dip Tank with lid (2 % HF).
  • Tank 4: Dump Rinse with lid.
  • Tank 5: Reflux heated bath (RCA Standard Clean 2-SC2).
  • Tank 6 and 8: small volume dip tanks for 4" wafer cassettes and samples.
  • Tank 7 and 9: small volume quartz heated baths for 4: wafers cassettes and samples.
 8 ft Heated wet chemical bench
 
Spin Rinse Dryers: Semitool PSC-101

These three tools are used for the DI water rinsing and spin-drying of the wafers after RCA cleaning.

  • Cassettes for 3, 4 and 6" wafers
  • Programmable recipes for rinse, quality rinse, purge and two dry cycles
