摘要: Generating drive signals of at least two RF power generators which supply RF power to a plasma process, in which at least two drive signals, each driving one RF power generator, are generated in an RF generator driver. Each drive signal is generated by a respective function generator, such as a digital sine generator, of the generator driver.
