Abstract
Methods of depositing a film using a plasma enhanced process are described. The method comprises providing continuous power from a power source connected to a microwave plasma source in a process chamber and a dummy load, the continuous power split into pulses having a first time and a second time defining a duty cycle of a pulse. The continuous power is directed to the microwave plasma source during the first time, and the continuous power is directed to the dummy load during the second time.
