In the microelectronics industry (semiconductor industry), poly is used at both the macro and micro scales. Single crystals are grown using the Czochralski, zone melting and Bridgman–Stockbarger methods. At the component level, polysilicon has long been used as the conducting gate material in MOSFET and CMOS processing technologies.
