摘要:
A method for leveling a wafer in a photolithography apparatus is disclosed, including inputting a wafer into the photolithography apparatus to be supported by a chuck, using at least three image capture devices to capture images of corresponding alignment marks on the wafer; and leveling the wafer according to the clarity of the images of the corresponding alignment marks on the wafer captured by the image capture device.
摘要:
A scanning electron microscope is provided. The scanning electron microscope includes an electron beam source generating a primary electron beam, a condenser lens converging the primary electron beam, a base plate with a diamond film formed on the surface thereof having an aperture for passing of the primary electron beam, and a scanning unit two-dimensionally scanning a specimen with the primary electron beam.

A calibration cassette pod for robot teaching and a method of using the calibration cassette pod are described. In the calibration cassette pod, a cassette pod body and a cassette pod door are first provided wherein the cassette pod body is constructed of a top panel, a bottom panel, two side panels and a front panel to enclose a cavity therein. A first plurality of ribs is formed on an inside surface of the cassette pod body, each having a predetermined depth sufficient to support an edge portion of a wafer. An optical detector housing is mounted on an opening in the front panel and is adapted for receiving an optical detector therein. An optical detector that includes a light emission source and a photo diode receiver for determining the position of the edge portion of the wafer is mounted in the optical detector housing.
摘要:
A primer tank having a nozzle assembly which uniformly distributes nitrogen or other vapor-generating gas against a primer liquid in the tank to generate a primer vapor for the priming of a semiconductor wafer substrate. The nozzle assembly includes a conduit to which is confluently attached a nozzle head having a nozzle plate. Multiple openings are provided in the nozzle plate to substantially uniformly distribute nitrogen or other inert gas against the surface of the primer liquid over a large area to generate a primer mist from the primer liquid and substantially reduce the formation of primer droplets in the tank.
