    Abstract: An antenna arrangement for generating an electric field inside a process chamber is provided. Generally, the antenna arrangement comprises a first loop disposed around an antenna axis. The first loop comprises a first turn with a first turn gap; a second turn with a second turn gap, where the second turn is concentric and coplanar with the first turn and spaced apart from the first turn, and where the antenna axis passes through the center of the first turn and second turn; and a first turn-second turn connector electrically connected between a second end of the first turn and a first end of the second turn comprising a spanning section between and coplanar with the first turn and the second turn and which spans the first turn gap and the second turn gap.

    Abstract: An apparatus for generating a fluid meniscus to be formed on a surface of a substrate is provided including a housing where the housing includes a housing surface to be placed proximate to a substrate surface of the substrate. The housing further includes a process configuration receiving region that is surrounded by the housing surface. The apparatus also includes a process configuration insert which has an insert surface where the process configuration insert is defined to fit within the process configuration receiving region of the housing such that the insert surface and the housing surface define a proximity face that can be placed proximate to the substrate surface of the substrate.

    Abstract: system and method of cleaning a substrate (202) includes a megasonic chamber (206) that includes a transducer (210) and a substrate (202). The transducer (210) is being oriented toward the substrate (202). A variable distance d separates the transducer (210) and the substrate (202). The system (200) also includes a dynamically adjustable RF generator (212) that has an output coupled to the transducer. The dynamically adjustable RF generator (212) can be controlled by a phase comparison of an oscillator output (306) voltage and a phase of an RF generator output voltage. The dynamically adjustable RF generator (212) can also be controlled by monitoring a peak voltage of an output signal and controlling the RF generator to maintain the peak voltage within a predetermined voltage range. The dynamically adjustable RF generator (212) can also be controlled by dynamically controlling a variable DC power supply voltage.
