A self-contained modular processing apparatus is disclosed for processing workpieces, and in particular, silicon wafers. The apparatus is constructed of framed modules which plug into a service facility docking subassembly and interlock therewith to make up a complete modular processing system for wafer processing. Each module may be provided with its own wafer transporting mechanism and includes a built-in CPU such that each module is an independent, stand-alone processing unit. Each processing unit, by being capable of independent operation, functions as a building block to configure a modular processing system capable of handling wafer flow in multiple directions while performing a multitude of processing functions or operations. Individual modules are arranged along a line of single fold symmetry such that a single transport mechanism may be employed for transferring wafers among adjacent modules.
A modular processing apparatus comprising a chassis having a pair of diagonal axes, a module attached to said chassis for performing at least one operation on a workpiece to be processed, transfer means attached to said chassis for transferring said workpiece from said module to a location remote therefrom for performing at least another operation on said workpiece, said module and said transfer means arranged along one of said axes and asymmetrically with respect to another of said axes, whereby the distance between said module and said transfer means is substantially equal to the distance between said transfer means and said location.
A modular processing apparatus comprising a first chassis having a pair of diagonal axes, a first module attached to said first chassis for performing at least one operation on a workpiece to be processed, a second chassis having a pair of diagonal axes, a second module attached to said second chassis for performing at least one operation on said workpiece to be processed, and transfer means attached to one of said first or second chassis for transferring said workpiece between said first module and said second module, said first module, said second module and said transfer means arranged along one of said axes and asymmetrically with respect to another of said axes, whereby the distance between said first module and said transfer means is substantially equal to the distance between said transfer means and said second module.
A modular processing apparatus comprising a first chassis having a pair of first diagonal axes, a first module attached to said first chassis and arranged symmetrically about one of said first diagonal axes, a second chassis having a pair of second diagonal axes, a second module attached to said second chassis and arranged symmetrically about one of said second diagonal axes, and transfer means attached to one of said first or second chassis and symmetrically arranged along the diagonal axis about which the corresponding first or second module is symmetrically arranged, said first module, said second module and said transfer means arranged asymmetrically with respect to another of said first diagonal axes and said second diagonal axes, whereby said transfer means transfers said workpiece between said first module and said second module over substantially equal distances.
