    摘要: Embodiments of batch processing apparatus and collapsible substrate support are provided herein. In some embodiments, a collapsible substrate support includes a base linearly moveable between a first position and a second position; and a first plurality of substrate support elements coupled to the base and including a lowermost substrate support element disposed in a fixed position with respect to the base and an uppermost substrate support element disposed above the lowermost substrate support element, wherein the uppermost substrate support element is linearly movable between a first position nearer to the lowermost substrate support element and a second position further from the lowermost substrate support element.

    摘要: Embodiments of showerheads are provided herein. In some embodiments, a showerhead for use in a process chamber includes a gas distribution plate having an upper surface and a lower surface; a plurality of channels extending through the gas distribution plate substantially perpendicular to the lower surface; a plurality of first gas delivery holes extending from the upper surface to the lower surface between adjacent channels of the plurality of channels to deliver a first process gas through the gas distribution plate; and a plurality of second gas delivery holes extending from the plurality of channels to the lower surface to deliver a second process gas therethrough without mixing with the first process gas.
