Solvents and GenSolv blends

CMC Materials produces high-purity solvents and other wet process chemicals under a concept we call “basic manufacturing.” As a basic manufacturer, we are vertically integrated to meet the stringent standards of semiconductor, silicon wafer, disk drive and other applications that need the coherent manufacturing, analytical and packaging capabilities of a single supplier. We supply solvents and solvent blends to many markets, including microelectronic, aerospace, biotechnology, pharmaceutical and optics, for such applications as:

  • Basic cleaning in semiconductor and related high-purity processes
  • Various etch-polishing processes
  • Ultra-low-residue vapor drying
  • Adhesion promoters for photoresists
  • Positive and negative photoresist stripping agents
  • Photoresist edge-bead-remover agents
  • High-purity intermediates for photoresist, spin-on-glass, low-k dielectric materials and anti-reflective coatings
  • Carriers for photoresist, abrasives, solvents and lubricants Coolants, wetting agents and thickeners.

Acetone

Acetone can be used for drying laboratory glassware, removing greasy or oily contaminants from work benches, or as a general photoresist stripper or edgebead remover.

Isopropyl Alcohol

Isopropyl alcohol (IPA) is used in IPA vapor drying of wafers. The vapor dryer advantages over spin-rinse dryers include: no water spots, decreased particles on the wafer, reduced chemical consumption and much reduced wafer breakage.
