Silicon Wafers - Electronics. In Electronics, A Silicon Wafer Is A Thin Slice Of Semiconductor Material, Such As A Silicon Crystal, Used In The Fabrication Of Integrated Circuits And Other Microdevices. The Wafer Serves As The Substrate For Microelectronic Devices Built In And Over The Wafer And Undergoes Many Microfabrication Process Steps Such As Doping Or Ion Implantation, Etching, Deposition Of Various Materials, And Photolithographic Patterning. Finally The Individual Microcircuits Are Separated And Packaged.
