TechniEtchACI2

Gold Etchant

 

General Information

TechniEtchACI2 is a highly effective and selective gold stripper. TechniEtchACI2 is an Iodine based Gold etchant, containing particular additives that greatly enhance stability and metal loading capability compared to conventional I2/I3 - based solutions .

Product Properties
  • High etch rate at room temperature
  • Low surface tension for enhanced wetting property
  • High stability even in presence of metal contamination (Cu, Ni…).
  • Loading & bath life independent of the solution Cu contamination level (up to 1g/l)
  • Enlarged loading capacity compared to standard I2/KI based solutions.
  • Better process controllability/reliability.
  • Low Toxicity compared to cyanide and HF/HNO3 based solutions
Selectivity

TechniEtchACI2 is compatible/etches selective to following materials:

  • Metals: no attack on Ni, Al, Ti, TiN
  • Metals: attack on Au, Cu, Sn, Pt, W
  • Semiconductor materials: Si, SiO2, Si3N4
