摘要： Embodiments of the present disclosure generally relate to methods and apparatus for measuring and controlling local impedances at a substrate support in a plasma processing chamber during processing of a substrate. A substrate support includes a plurality of substrate support pins wherein the radio frequency voltage, current and phase of each of the plurality of substrate support pins are measured and impedances of the support pins are adjusted in real time. Each of the substrate support pins is coupled to an associated adjustable impedance circuit that may be remotely controlled. In one embodiment a variable capacitor is used to adjust the impedance of the impedance circuit coupled to the associated substrate support pin and may be remotely adjusted with a stepper motor. In another embodiment a microcontroller may control the impedance adjustments for all of the plurality of substrate support pins and may be used to track these impedances with each other and with a bulk impedance of the plasma processing chamber.

摘要： The present disclosure provides systems and methods for processing channel structures of substrates that include positioning the substrate in a first processing chamber having a first processing volume being in fluid communication with a plasma source. The substrate can include a channel structure with high aspect ratio features having aspect ratios greater than about 20:1. The method can also include forming an oxide cap layer over a silicon-containing layer of the channel structure and exposing the oxide cap layer to a hydrogen-or-deuterium radical to nucleate the silicon-containing layer of the channel structures of the substrate. Forming the oxide cap layer and exposing the channel structure with the hydrogen radical occurs in the first processing chamber to form a nucleated substrate. The method can also include positioning the nucleated substrate in a second processing chamber with a second processing volume and heating the nucleated substrate in the second processing chamber.
