Production of Silicon Chips

Inside every modern computer or other data-processing wonder is a microprocessor bearing millions of transistors sculpted from silicon y chemicals and light. Silicon, the second most abundant element on Earth, is used extensively in transistors, integrated circuits, photoelectric devices, and other electronic devices. A pure crystal of silicon does not conduct electricity unless traces of other substances are diffused or doped onto it. Therefore silicon must be manufactured in a specific way in order for …

…to the gate. Aluminum is then spread over the surface. Masking and etching leaves three metal electrical conatacts. Up to five hundred chips may be created on a single wafer. Each is tested, and working chips are separated with a diamond-tipped saw and mounted in a plastic casing. They are connected to metal legs by fine gold wire. Tiny chips of silicone are connected forming complex circuits that are used in computers, satellites and spacecraft.
