Patent ID: 7845529

Claim:
A substrate process apparatus, comprising: a first scribing portion for creating a scribe line on a first main surface of a plurality of substrates mounted and aligned on a first table; a second scribing portion for creating a scribe line on a second main surface of the plurality of substrates as the plurality of substrates are mounted and aligned on a second table after being processed in the first scribing portion, so that the second main surface, which is on the side opposite to the first main surface, faces upward; and a conveying robot for collectively conveying the plurality of substrates at the same time between the first scribing portion and the second scribing portion and flipping the respective substrates so that either the first surface or the second surface faces upward during conveyance, the conveyance robot being used to convey the substrates, characterized in that the conveying robot is provided with a number of suction members, each of the suction members having a suction surface and a rotational axis for flipping said suction surface upside-down by rotating by 180°, the rotational axes for the suction members being supported in such a state as to be spaced from and aligned parallel to each other, and is provided with a substrate sucking and rotating means for simultaneously rotating the suction members around their respective rotational axes so that the plurality of substrates held by the suction surfaces are simultaneously flipped, wherein the rotational axis of each suction member extends in the longitudinal direction and passes through approximately the center in the width in the lateral direction; and wherein the substrate sucking and rotating means comprises: a rotational axis driving portion for rotating the rotational axis of the suction members; and a rotational axis moving portion for changing the distance between the rotational axes of adjacent suction members before or while rotating the rotational axes.
