The ion implanters are all made in China and can provide a one-stop service for global chipmakers, the CETC added. CETC subsidiary Electronics Equipment Group has developed an ion implanter family ranging from medium current, high current and high energy implanters, to implanters for special applications and third-generation semiconductors, which can cover 28-nanometer manufacturing process. In the chip manufacturing process, an ion implanter puts different chemical elements, in the form of ions with programed energy, into semiconductor materials to alter the materials' electrical performances.
