    摘要: A method and apparatus are directed to providing a dopant profile adjustment solution in plasma doping systems for meeting both concentration and junction depth requirements. Bias ramping and bias ramp rate adjusting may be performed to achieve a desired dopant profile so that shallow and abrupt junctions in vertical and lateral directions are realized that are critical to device scaling in plasma doping systems.
