Axcelis Technologies Inc

A maker of ion implantation equipment, the machines that fire charged particles into silicon wafers to build the chips inside phones, cars, and power electronics. Its flagship Purion line of implanters serves chipmakers worldwide, with a specialized Purion Power Series for silicon-carbide power devices. The company traces its roots to 1978, when founders launched Nova Associates in a shed that had once been a chicken hatchery; after joining Eaton Corporation, the business was spun off and rebranded as Axcelis in 2000.
