  • Patent number: 11990363
    Abstract: A wafer support pin lifting device includes a support plate, a slide block and a lifting pole. The support plate is for supporting multiple support pins. The slide block is slidably connected to an inner wall of a cavity so that the slide block slides relative to the cavity. The lifting pole has a first end, a second end and a third end. The first end is connected to the support plate, the second end is pivotally connected to the slide block, and the third end is connected to an actuator. With the pivotal connection between the second end of the lifting pole and the slide block, the lifting pole approaching the high position causes the support plate to be approximately horizontal, and the lifting pole approaching the low position causes the support plate to be tilted.

  • Publication number: 20230274957
    Abstract: The invention discloses a semiconductor multi-station processing chamber. Each of the multiple station includes a downward concave accommodation defined by walls and receives a pedestal therein. The pedestal and the walls define a first gap. A showerhead plate mounted on an upper lid above the pedestal to define a processing region. A second gap for supply swiping gas is defined between the showerhead plate and the upper lid. An isolation member is liftable between the downward concave accommodation and the showerhead plate to optionally encircle a processing region defined by the pedestal and the showerhead plate or to retract back into the downward concave accommodation. Such that, when the isolation member surrounds and encircles the processing region, the station is able to be structurally isolated from its neighboring one station.
