Abstract
Embodiments of the present disclosure provide a sputtering chamber with in-situ ion implantation capability. In one embodiment, the sputtering chamber comprises a target, an RF and a DC power supplies coupled to the target, a support body comprising a flat substrate receiving surface, a bias power source coupled to the support body, a pulse controller coupled to the bias power source, wherein the pulse controller applies a pulse control signal to the bias power source such that the bias power is delivered either in a regular pulsed mode having a pulse duration of about 100-200 microseconds and a pulse repetition frequency of about 1-200 Hz, or a high frequency pulsed mode having a pulse duration of about 100-300 microseconds and a pulse repetition frequency of about 200 Hz to about 20 KHz, and an exhaust assembly having a concentric pumping port formed through a bottom of the processing chamber.
