Abstract:
1. A processing apparatus comprising: a processing chamber; and a loader chamber disposed at a side surface of the processing chamber, wherein the loader chamber includes: two loading ports positioned to be spaced apart from each other along the side surface, each of the loading ports mounting thereon a cassette accommodating therein a plurality of target objects; a transfer unit provided between the loading ports, the transfer unit transferring the target objects between the loading ports and the processing chamber; and a pre-alignment mechanism provided on the transfer unit, for positioning the target objects, wherein each of the loading ports has a direction switching mechanism for switching a direction of the cassette and an opening/closing mechanism for opening/closing a lid of the cassette facing the transfer unit through the direction switching mechanism, wherein the direction switching mechanism has a mounting portion for mounting thereon the cassette; and a rotational body for rotating the mounting portion, wherein a center of the target objects in the cassette is offset from a center of the rotational body by a specific distance, and the mounting portion is eccentrically rotated by the rotational body, and wherein by rotating the rotational body at a specific angle, the lid of the cassette is made to face the opening/closing mechanism and, also, the cassette becomes closer to a position where it is opened and closed by the opening/closing mechanism by the specific distance.
