CPS Wet Etching Bench

With many years of experience working in the Chemical and Process Industries, the CPS  Acid Etch Bench, consists of a 3 station wet cleaning and etching process, used in semiconductor manufacturing or other high technology products. 

Each station consists of an acid tank and DI (deionized) water in a rinsing tank. Used in multiple industries such as PV and Semiconductor wafer manufacture or other substrates, usually in multiple batch sizes are immersed in a predetermined sequence. 

De-Ionizing water supply is controlled from the front control panel, along with air sparge to tanks via Each station has a control panel which controls:

  • The supply of de-ionized water
  • The operation of an air sparge, which increases the efficiency of the wet etching process.
  • Solenoid activated tank drain. 

Bench fumes are managed by a common extraction ducting located at the rear of the bench

CPS Wet Benches are used in the manufacturing process of the following industries

  • Semiconductor
  • Solar
  • MEMS
  • LED
  • Bio-Medical
  • Disc Drive 


Cleaning and preparation

  • Examples: RCA clean, Standard clean (SC1 or SC 2), HF last


  • Etching films like Si, SiO2, doped silicate glass, Si3N4
  • Alkaline etching of crystalline using KOH, TMAH, EDP


  • Photoresist and residue removal


  • For solar cells and MEMS devices


  • Electroless and electrolytic applications
  • Chemistries include: copper, nickel, gold; more exotic requirements
