Webchemical) (chemical) Physical etching: (e.g. sputtering etch)-mechanical/physical interaction-positive ions are accelerated and strike substrate with high kinetic energy, some energy is then transferred to surface atoms, which leads to material removal-negative ions cannot reach the wafer and therefore plays no role in the etching in doing moral acts we make use of

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride (British spelling) is an inorganic compound with the formula SF6. It is a colorless, odorless, non-flammable, and non-toxic gas. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a … See more Sulfur hexafluoride on Earth exists primarily as a man-made industrial gas, but has also been found to occur naturally. SF 6 can be prepared from the elements through exposure of S 8 to F 2. This was also the method … See more The electrical power industry used about 80% of the sulfur hexafluoride produced in 2000, mostly as a gaseous dielectric medium. Other main uses as of 2015 included a silicon etchant for semiconductor manufacturing, and an inert gas for the casting of See more Sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled.
