Inputs of Intel’s site A clean room Purified Water Silicon Wafers- What the micro-chips are made on Labour- Qualified graduates in engineering and science Electricity- Power source Clean Rooms- where the microchip manufacturing takes place Air Purification systems- to eliminate dust in the clean rooms and clean the air Capital- Financial investment in the new techniques to stay ahead of the competition A clean room

Processes of Intel In the clean rooms workers wear clothing to prevent dust from body and clothes from reaching the silicon wafers 1 Microchips are made from the wafers this includes about 300 manufacturing steps 2 A large number of switches are created on the microchips to test if the microchips work and then shipped abroad 3
