Advanced semiconductor chemicals, customizable chemistry platforms and low volatility silicones from Avantor® are engineered to help semiconductor fabs and MicroElectroMechanical Systems (MEMS) manufacturers meet process improvement goals faster, enhance product quality and speed up ramp time to the next node.

Our proven portfolio of J.T.Baker® semiconductor chemicals—photoresist strippers, residue removers and materials etching and cleaning chemistries—are used by leading semiconductor fabs worldwide.

And our NuSil® brand silicones support various levels of semiconductor packaging, including thermally and electrically conductive silicones for EMI and RFI shielding applications.

Enhancing FEOL and BEOL performance

Avantor’s J.T.Baker® chemicals for semiconductor and MEMS fabrication are used in multiple front-end-of-line (FEOL) and back-end-of-line (BEOL) process steps. Engineered to parts-per-trillion levels of purity, they can help fab operators:

  • Efficiently and thoroughly remove bottom and sidewall residues
  • Meet demanding requirements of the integration of novel metal integration schemes
  • Utilize residue removers that offer selective etch capabilities
  • Increase process margins for post-etch residue and sacrificial layer removal
  • Consolidate wet process steps to lower total cost of ownership
