Web5 apr. 2024 · In SiO 2, the Silicon (Si) is bonded to Oxygen (O). And again, you know that the ionic charge of O is 2-. So here also you can easily say that the ionic charge of Si should be 4+, then only it will get canceled out. Hence the ionic charge of Silicon in SiO 2 is 4+. Example 3: SiH4 Similarly in SiH 4, the Silicon (Si) is bonded to Hydrogen (H). WebIon implantation is a process used in the semiconductor industry to introduce dopants or impurities into a material, typically a silicon wafer, in order to alter its electrical properties.
