Abstract:
1. An alignment arrangement for aligning a semiconductor process tool to a track system; comprising: an alignment apparatus spaced at a predetermined location relative to said track system; said alignment apparatus being adapted for projecting laser beams toward said track system so as to facilitate centering and aligning said alignment apparatus with said track system; said alignment apparatus comprising a jig base member fastenable to a floor of a semiconductor fabrication facility, said track system including an automated overhead transport system for conveying semiconductor wafer-containing pods for processing of said wafer-containing pads by said process tool; said laser projecting arrangement comprising a plurality of laser mounts which are displaceably supported on said jig base member; wherein said plurality of laser mounts comprises a primary laser mount for initially centering said alignment apparatus to said track system; and secondary laser mounts or prism attachments for determining the alignment of FOUP load ports relative to said track system in a precision interface with said at least one process tool; and at least one semiconductor process tool in preset alignment with said track system.
