Caption: Stage in the manufacture of high-performance semiconductor wafers: an engineer loads 2-inch diameter gallium arsenide (GaAs) wafers onto a planetary mounting for a FC-1800 fast-cycle coater, a sputtering system that deposits thin metallic films onto the wafer. Semiconductor wafers are the building-blocks of individual integrated circuits and have traditionally been made of silicon. Chips based on GaAs are up to 10 times faster at handling data than silicon & are more resistant to corruption by radiation. Photographed at Temescal, a member of The BOC Group plc, at their plant in Berkeley, California.
