Tetrafluoromethane (CF₄)

Tetrafluoromethane (CF₄) is an inert, colorless gas used primarily as an etchant in the electronics and semiconductor industry. It plays a critical role in the precise etching of silicon wafers, contributing to the production of integrated circuits and microelectronic devices. Besides its etching capabilities, CF₄ also serves as a dielectric agent, offering excellent electrical insulation properties. Its stability and non-flammability make it suitable for use in controlled environments where safety and performance are paramount.
