Claim Text:
1. A wafer-processing apparatus, comprising: eight or ten reactors with identical capacity for processing wafers on the same plane, constituting four or five discrete units, each unit consisting of two reactors arranged with their fronts aligned in a line, each reactor being a single-wafer processing reactor; a wafer-handling chamber including two wafer-handling robot arms, each having at least two end-effectors accessible to the two reactors of each unit simultaneously, said wafer-handling chamber having a polygonal shape having four or five sides corresponding to and being attached to the four or five discrete units, respectively, and one additional side for a load lock chamber, all the sides being disposed on the same plane; a load lock chamber for loading or unloading two wafers simultaneously, said load lock chamber being attached to the one additional side of the wafer-handling chamber, wherein each wafer-handling robot arm is accessible to the load lock chamber; and a sequencer programmed to perform, using the two wafer-handling robot arms wherein one arm is loaded with unprocessed wafers and the other arm is unloaded,
