Electronic Materials

CP Lab Chemicals Solvents and Wet Chemicals Used in Electronics and Silicon Wafer Production:

• acetic acid, acetone, ammonium fluoride, ammonium hydroxide, hydrochloric acid, hydrogen fluoride anhydrous or acids or pyridine complex, hydrogen peroxide, isopropyl alcohol, nitric acid, phosphoric acid, and sulfuric acid
• silanes and siloxanes, dichlorosilanes and trichlorosilanes, silicon tetrachloride, disilane, methylsilanes, tetraethylorthosilicate, silicon tetrafluoride, germanes
• ammonia, tungsten hexafluorides
• Fluorocarbons including trifluoromethane, tetra-fluoromethane, difluoromethane, fluoromethane, hexafluoroethane, pentafluoroethane, octafluoropropane, and octafluorocyclobutane

SAFETY INFORMATION: Hydrogen fluoride is extremely dangerous and should only be handled by highly-trained personnel. Failure to follow this could result in injury or death. For solutions of >30% HF double nitrile gloves are recommended and the use of C-alloy layered gloves or HF resistant gloves is needed. For 4 hours or more of HF exposure: butyl rubber, neoprene rubber, viton/butyl rubber, Barrier®, Silver Shield/4H®, Trellchem® HPS, Trellchem® VPS, Saranex®, and Tychem®
