Abstract
A substrate transfer apparatus transfers a substrate in a vacuum chamber. The substrate transfer apparatus includes an elevating robot, a travel robot and a transfer robot. The elevating robot includes an elevating plate through which through-holes are formed, and hollow elevating shafts, wherein each central axis of the hollow elevating shafts corresponds to each center of the through-holes, wherein the elevating robot is sealably coupled with a vacuum chamber through-hole. The travel robot includes a travel arm platform through which coupling holes are formed, wherein each of the hollow elevating shafts is inserted into each lower space of each of the coupling holes, a first travel arm part including a (1_1)-st and a (1_2)-nd travel link arms, second travel arm parts including a (2_1)-st and a (2_2)-nd travel link arms, and a transfer robot coupling part coupled with the (1_2)-nd and the (2_2)-nd travel link arms.
