Abstract:
A transfer apparatus for a semiconductor process, comprising:an articulated arm unit attached to a support base to be stretchable/retractable within a horizontal plane, the articulated arm unit having a distal end arm which reciprocates in a first direction when the articulated arm unit stretches and retracts, the articulated arm unit being rotatable within a horizontal plane relative to the support base; a support member arranged on the distal end arm to support a target substrate; a pair of temporary shelves configured to support the target substrate, and disposed to sandwich the support member when the articulated arm unit retracts, the temporary shelves being arranged not to rotate together with the articulated arm unit; a main driving mechanism configured to stretch/retract the articulated arm unit; a rotational driving mechanism configured to rotate the articulated arm unit; and a vertical driving mechanism configured to vertically drive the support member and the temporary shelves relative to each other in order to transfer the target substrate therebetween.
