Patent ID: 8800774

Claim:
A substrate container for storing at least one substrate, comprising: a container door for access into an inner region within an enclosure of the substrate container; and a housing assembly for encompassing a substrate, the housing assembly having: a plurality of side walls defining the enclosure, the side walls located on left and right sides of the container door when the container door is closed, the container door used to allow access of the housing assembly to the substrate when present for transporting the substrate; and a support structure disposed within the housing assembly, the support structure having a plurality of cantilevered support extensions extending into the inner region of the housing assembly, the plurality of cantilevered support extensions arranged as horizontally coplanar pairs, wherein cantilevered support extensions of different horizontal planes are vertically aligned, wherein each cantilevered support extension has a proximal end and a distal end, wherein the proximal and distal ends of each cantilevered support extension are located on opposite sides of the longest dimension of each cantilevered support extension, wherein each cantilevered support extension includes a first support pad at the distal end and a second support pad at the proximal end for supporting the substrate when present, wherein the access to the substrate when present is provided outside of each of the cantilevered support extensions, wherein the access is provided to the substrate when present from gaps extending between the cantilevered support extensions and the side walls of the enclosure, wherein the gaps facilitate vertical movement of arms of an end effector without contacting the support structure.
