<unk>  is the process used to create chips, the integrated circuits that are present in everyday electrical and electronic<unk> s. It is a multiple-step sequence of photographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material.
Silicon is the most commonly used<unk>  material today, along with various compound<unk> s.
The entire manufacturing process from start to packaged chips ready for shipment takes six to eight weeks and is performed in highly specialized facilities referred to as fabs.
