The group's principal activities are to design, manufacture, market and service semiconductor processing equipment used in the fabrication of integrated circuits. the group's customers include many of the world's semiconductor manufacturers. semiconductor wafers are subjected to a complex series of process steps that result in the simultaneous creation of many individual integrated circuits. etch and chemical mechanical planarization (cmp) products selectively remove portions of various films from the wafer to create an integrated circuit. the group's trademarks are lam, transformer coupled plasma, teres, exelan, 4520xle, rainbow, alliance, linear planarization technology, lpt, cmc, synergy, ontrak, synergy integra, tcp, lam research and dss-200. export sales accounted for 44% of fiscal 2002 revenues.
