Silicon

Generally present as a silicate, these being found in many rocks, clays and soils. Silicon is obtained by reducing silica (sand, SiO2 ), with carbon. Further purification of the element for applications requiring high purity material (e.g. semi conductor devices) is achieved by zone refining, the resulting purity being better than 1:109....

silicon

A non-metallic element used in the semiconductor industry as a substrate for multiple layers of material, built to form transistors and integrated circuits. Silicon is grown from a crystal to form a cylinder shaped ‘log.` Slicing the logs into sections 1/40 of an inch thick creates bare wafers.
