    摘要: Methods of semiconductor processing may include performing a process on a semiconductor substrate. The semiconductor substrate may be seated on a substrate support positioned within a processing region of a semiconductor processing chamber. The methods may include flowing a first backside gas through the substrate support at a first flow rate. The methods may include removing the semiconductor substrate from the processing region of the semiconductor processing chamber. The methods may include performing a plasma cleaning operation within the processing region of the semiconductor processing chamber. The methods may include flowing a second backside gas through the substrate support at a second flow rate. At least a portion of the second backside gas may flow into the processing region through accesses in the substrate support.

    摘要: A band-shaped Si pillar having a mask material layer on the top portion thereof is formed on a P+ layer. SiGe layers having mask material layers on the top portions thereof are then formed in contact with the side surfaces of the band-shaped Si pillar and the surfaces of N+ layers and the P+ layer. Si layers having mask material layers on the top portions thereof are then formed in contact with the side surfaces of the SiGe layers and the surfaces of the N+ layers. The outer peripheries of the bottom portions of the Si layers are then removed using the mask material layers as a mask to form band-shaped Si pillars. The mask material layers and the SiGe layers are then removed. Si pillars separated in the Y direction are then formed in the band-shaped Si pillars.

    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.
