Computer Chip Life Cycle The Environmental Literacy Council

Energy is one of the inputs of the mining and purifying process. The output is purified silicon, which gets shipped to a computer chip factory. The computer chip factory then takes the purified silicon and makes it into a crystal wafer form. The purified silicon is an input of the manufacturing process. Only about 43% of the pure silicon crystal used in the process becomes part of the chip.
