    • Embodiments disclosed herein generally provide a load lock chamber capable of controlling the temperature of the substrate therein. The load lock chamber may have one or more cooling fluid introduction passages that extend across the chamber. Cooling fluid, such as nitrogen gas, may flow through the cooling fluid passage and enter the load lock chamber. The cooling fluid passages may have openings to permit the cooling fluid to exit the passages and enter the load lock chamber. The openings may be arranged to permit a greater amount of cooling fluid to enter the load lock at locations corresponding to the substrate positions that are in contact with an end effector that places the substrate into the load lock chamber. Additionally, the openings may be arranged to permit a greater amount if cooling fluid to enter the load lock chamber in the center of the chamber as compared to the edge of the chamber.
    • 本文公开的实施例通常提供能够控制其中的基板的温度的负载锁定室。 加载锁定室可以具有延伸穿过该腔室的一个或多个冷却流体引入通道。 诸如氮气的冷却流体可以流过冷却流体通道并进入负载锁定室。 冷却流体通道可以具有允许冷却流体离开通道并进入负载锁定室的开口。 开口可以被布置成允许更大量的冷却流体在对应于与将基板放置到负载锁定室中的端部执行器接触的基板位置的位置处进入负载锁定。 此外,与腔室的边缘相比,如果冷却流体进入腔室中心的负载锁定室,则开口可以被布置为允许更大的量。

    • Embodiments disclosed herein relate to a large vacuum chamber body that has been welded together. The chamber body may have a high emissivity coating on at least one surface therein. Due to the large size of the chamber body, the chamber body may be formed by welding several pieces together rather than forging the body from a single piece of metal. The pieces may be welded together at a location spaced from the corner of the body, which may be under the greatest stress during evacuation, to ensure that the weld, which may be the weakest point in the body, does not fail. At least one surface of the chamber body may be coated with a high emissivity coating to aid in heat transfer from incoming, heated substrates. The high emissivity coating may increase substrate throughput by lowering the time that may be needed to reduce the substrate temperature.
    • 本文公开的实施例涉及已经焊接在一起的大型真空室主体。 腔体可以在其中的至少一个表面上具有高发射率涂层。 由于腔室主体的尺寸较大,可以通过将多个部件焊接在一起而不是从单个金属件锻造主体而形成腔体。 这些部件可以在与身体的角部间隔开的位置处被焊接在一起,该位置在排空期间可能处于最大的应力下,以确保可能是身体中最弱点的焊缝不会失效。 室主体的至少一个表面可以涂覆有高发射率涂层,以帮助来自加热的基底的热传递。 高发射率涂层可以通过降低降低衬底温度所需的时间来增加衬底通量。
