  • Patent number: 10538843
    Abstract: A vaporizer includes a main body including a first body and a second body. The first body has an upper portion narrowing in a direction of a height of the first body and the second body has a cavity in which the first body is positioned. A mixing chamber is between the first and second bodies. The second body includes a carrier gas injection path connected to a carrier gas inlet formed in an upper portion of the mixing chamber. The carrier gas injection path carries a carrier gas. A source material injection path is connected to a source material inlet formed in the mixing chamber. The source material injection path carries a liquid source material. A discharge is connected to an outlet formed in a lower portion of the mixing chamber. A mixed fluid including the carrier gas and the liquid source material is discharged through the discharge path.

  • Patent number: 8600150
    Abstract: A wafer aligning apparatus includes a laser sensor that generates a trigger signal, a CCD camera imaging a wafer in response to the trigger signal, a signal processing unit that calculates a center alignment correction value for the wafer, and a robot controller that receives the center alignment correction value to control movement of a transfer robot. The laser sensor generates the trigger signal in accordance with a change in reflected light detected by the laser sensor, the change in the amount of reflected light being detected by the laser sensor when a boundary between a blade of the transfer robot and a coupler of the transfer robot passes under the laser sensor.

  • Patent number: 7813542
    Abstract: Embodiments of the invention provide a wafer aligning apparatus and a wafer aligning method. In one embodiment, the wafer aligning apparatus comprises an imaging unit adapted to take an image of a wafer being transferred from a load lock chamber to a transfer chamber and adapted to convert the image into digital signals, and a signal processing unit adapted to calculate a center alignment correction value for the wafer by comparing the digital signals to a master image stored in the signal processing unit. The wafer aligning apparatus further comprises a robot controller adapted to receive the center alignment correction value from the signal processing unit and adapted to control a transfer robot in accordance with the center alignment correction value to provide the wafer to a process chamber such that the center of the wafer is substantially aligned.
