Reaction Mechanisms of Charcoal and Coke in the Silicon

Carbon from charcoal, wood chips, coal and coke is used as reduction agent in the silicon process to release the silicon from quartz. This process requires high temperatures and a lot of energy. The content of trace elements in both the quartz and the reduction materials determines the purity of the produced silicon metal (Myrhaug and Tveit [1]).

BASIC INTEGRATED CIRCUIT MANUFACTURING The Chip

Silicon for semiconductor applications is taken from quartzite, the rock form of silicon dioxide. Quartzite has trace levels of other elements that must be removed in the purification process. The purifying of quartzite consists of reacting the quartzite with some form of carbon material. The carbon may be in the form of coal, coke, or wood.
