Abstract
The present invention provides a cassette positioning device and a semiconductor processing apparatus. The cassette positioning device includes: a positioning baseplate arranged horizontally and connected with the lifting device; a rotatable positioning, plate, which is located on the positioning baseplate, has one end rotatably connected with one end of the positioning baseplate, and is provided thereon with a positioning assembly; and a support column arranged under the rotatable positioning plate. The support column and the positioning baseplate can move relatively in the vertical direction, such that the rotatable positioning plate is pushed up by the support column and rotates to be inclined relatively to the positioning baseplate when the support column rises to a preset highest position relatively to the positioning baseplate, and the rotatable positioning plate and the positioning baseplate are stacked on the support column in parallel when the support column is located at a preset lowest position. In the cassette positioning device and the semiconductor processing apparatus, positions, in horizontal direction, of all the wafers in the cassette can be consistent, so that the wafers taken out by the mechanical arm can be located at uniquely specified positions on the mechanical arm.
