摘要： Apparatus, methods, and computer programs for semiconductor processing in a capacitively-coupled plasma chamber are provided. A chamber includes a bottom radio frequency (RF) signal generator, a top RF signal generator, and an RF phase controller. The bottom RF signal generator is coupled to the bottom electrode in the chamber, and the top RF signal generator is coupled to the top electrode. Further, the bottom RF signal is set at a first phase, and the top RF signal is set at a second phase. The RF phase controller is operable to receive the bottom RF signal and operable to set the value of the second phase. Additionally, the RF phase controller is operable to track the first phase and the second phase to maintain a time difference between the maximum of the top RF signal and the minimum of the bottom RF signal at approximately a predetermined constant value, resulting in an increase of the negative ion flux to the surface of the wafer.

摘要： Embodiments for processing a substrate in a pulsed plasma chamber are provided. A processing apparatus with two chambers, separated by a plate fluidly connecting the chambers, includes a continuous wave (CW) controller, a pulse controller, and a system controller. The CW controller sets the voltage and the frequency for a first radio frequency (RF) power source coupled to a top electrode. The pulse controller is operable to set voltage, frequency, ON-period duration, and OFF-period duration for a pulsed RF signal generated by a second RF power source coupled to the bottom electrode. The system controller is operable to set parameters to regulate the flow of species between the chambers to assist in the negative-ion etching, to neutralize excessive positive charge on the wafer surface during afterglow in the OFF period, and to assist in the re-striking of the bottom plasma during the ON period.

摘要： Methods and apparatus for operating the plasma processing chamber of a plasma processing tool in at least two modes are disclosed. In the first mode, the substrate-bearing assembly is movable within a gap-adjustable range to adjust the gap between the electrodes to accommodate different processing requirements. In this first mode, RF ground return path continuity is maintained irrespective of the gap distance as long as the gap distance is within the gap-adjustable range. In the second mode, the substrate bearing assembly is capable of moving to further open the gap to accommodate unimpeded substrate loading/unloading.
