Solution
Wafer fabrication refers to the process of creating a semiconductor wafer, which is used in electronics for the fabrication of integrated circuits. This process involves several steps, including:
-
Silicon Processing: This is the first step in wafer fabrication where pure silicon is converted into a crystalline state to be used as the base material for the wafer.
-
Crystal Growth: In this step, the crystalline silicon is grown into a large cylindrical ingot.
-
Wafer Slicing: The silicon ingot is then sliced into thin wafers.
-
Cleaning: The wafers are cleaned to remove any impurities.
-
Circuit Creation: Finally, the integrated circuits are created on the wafer through a process called photolithography.
So, wafer fabrication means converting silicon to usage wafers, crystal growth, and cleaning of wafers.
