Product Description
Product Description
Tungsten hexafluoride (WF6) is a chemical compound consisting of one tungsten atom bonded to six fluorine atoms. It is a colorless gas at room temperature and has a pungent odor. Tungsten hexafluoride is highly reactive and is primarily used in various industrial processes, particularly in the semiconductor industry.
Here are some key properties and applications of tungsten hexafluoride:
Properties:
- Formula: WF6
- Molar mass: 297.84 g/mol
- Appearance: Colorless gas
- Melting point: -2.8°C (-27.04°F)
- Boiling point: 17.1°C (62.78°F)
- Density: 2.4 g/cm³ (at 25°C)
Applications:
Chemical Vapor Deposition (CVD): Tungsten hexafluoride is commonly used in the CVD process to deposit thin films of tungsten onto surfaces, such as silicon wafers, to create electrical contacts or interconnects in microelectronics.
Atomic Layer Deposition (ALD): WF6 is utilized in ALD processes to deposit tungsten films with precise thickness and uniformity in semiconductor manufacturing.
Tungsten Source: It serves as a precursor for the production of pure tungsten metal through reduction processes.
Etching: Tungsten hexafluoride is also used as an etchant in the semiconductor industry to selectively remove tungsten layers during the fabrication of integrated circuits.
Due to its reactivity and potential hazards, tungsten hexafluoride should be handled with caution. It is corrosive to many materials, reacts violently with water, and can release toxic hydrogen fluoride gas upon contact with moisture. Proper safety protocols and equipment must be followed when working with this compound.
