Abstract:
1. A vertical substrate transfer apparatus which carries a substrate having opposite processing surfaces in a nearly upright position to a processing chamber, comprising: a carrier for supporting the substrate so that either surface of the substrate is processable, the carrier including: an intake mechanism for transferring the substrate onto the carrier; a carrying chamber housing the carrier on its path of progression to the processing chamber; a position changing mechanism for changing the carrying position of the carrier, the position changing mechanism arranged between the intake mechanism and the carrying chamber; and the processing chamber arranged for processing one surface of the substrate, wherein; the position changing mechanism includes means for changing position of the carrier from a first position in which a processing surface of the substrate is directed to a first direction or to a second position in which the processing surface is directed to a second direction different from the first direction, and for selecting either one of the first and second positions according to a desired orientation of the substrate to be carried in the processing chamber.
