A wafer probe station is equipped with an integrated environment control enclosure substantially surrounding a supporting surface for holding a test device, such enclosure limiting fluid communication between the interior and exterior of the enclosure and preferably also providing EMI shielding and a dark environment. The limited communication between the interior and exterior of the enclosure is kept substantially constant despite positioning movement of either the supporting surface or probes. The positioning mechanisms for the supporting surface and probes each are located at least partially outside of the enclosure.
We claim: 1. A probe station comprising: (a) a chuck for supporting a test device; (b) at least one support for a probe to contact said test device; (c) an enclosure and an electrically conductive lower member having a substantially horizontal surface spaced vertically below said chuck, said enclos
We claim: 1. A probe station comprising: (a) a chuck for supporting a test device; (b) at least one support for a probe to contact said test device; (c) an enclosure and an electrically conductive lower member having a substantially horizontal surface spaced vertically below said chuck, said enclosure defining an upper aperture for receiving said support and a lower aperture defined by said lower member capable of relative lateral movement with respect to said upper aperture; and (d) a receptacle for alternately and detachably receiving a user-selected one of a single guarded cable suitable for low-current measurements and plural cables suitable for a Kelvin connection to said test device. 2. The probe station of claim 1 having a positioner extending through said lower aperture and where said lower member comprises overlapping, relatively slidable members extending laterally beneath said surface, said slidable members being of different sizes and defining openings of different sizes. 3. The probe station of claim 2, wherein said enclosure has an upper member extending substantially laterally over said chuck. 4. The probe station of claim 2 wherein said positioner includes a motor assembly beneath said slidable members for moving said positioner. 5. The probe station of claim 1 wherein said enclosure includes a door for selectively accessing said chuck. 6. The probe station of claim 1, said enclosure substantially shielding said chuck against electromagnetic interference. 7. The probe station of claim 1, said enclosure substantially shielding said chuck against said light. 8. The probe station of claim 1, said enclosure limiting fluid communication between the interior and exterior of said enclosure.
