Abstract:
1. A conveyor for moving a semiconductor wafer container between a first location and a second location, the semiconductor wafer container having a first contact surface and a second contact surface, comprising: a first belt having a first support surface for movably supporting the container by the first conact surface, the first support surface being ribbed; a second belt having a second support surface for movably supporting the container by the second contact surface, the second suport surface being ribbed; the first belt and the second belt each having a raised guide that transistions from the respective first and second support surfaces, the raised guide defines a lateral restraint for the container; a first drive assembly for moving the first belt, the first drive assembly having at least one support wheel between end wheels, the first belt being extended between the end wheels to define the first support surface; and a second drive assembly for moving said second belt, the second drive assembly having at least one support wheel between end wheels, the second belt being extended between the end wheels to define the second suppot surface.
