Patent ID: 8348584

Claim:
A conveyer system comprising: a load port having a first platform on whose upper surface a carrier for conveying a semiconductor substrate may be placed and providing communication between an isolated space isolated from outside, in which a semiconductor production device performing processing for semiconductor production on the semiconductor substrate may be disposed, and a housing space provided inside the carrier placed on the first platform and housing the semiconductor substrate, wherein the first platform has a first notch extending into the first platform and opening at one lateral surface of the first platform, a relay unit disposed adjacent to the first platform relative to the horizontal direction and having a third platform on whose upper surface the carrier may be temporarily placed, wherein the third platform has a second notch having an opening horizontally facing the opening of the first notch, and which extends into the third platform from a lateral surface of the third platform horizontally facing the one lateral surface of the first platform, and a first conveyer device disposed below the first platform and the third platform, the first conveyor device having a second platform on whose upper surface the carrier is to be placed, and a first moving unit for moving the second platform in a vertical direction and in a horizontal direction, wherein the second platform is movable by the first conveyor device in the vertical direction while passing through the first notch, and is also movable by the first conveyor device in the horizontal direction between the first platform and the third platform by passing horizontally between the horizontally facing openings of the first notch and the second notch.
