  • Low cost


    Lab Assistant Features and Advantages


  • StereoZoom Microscope
  • 2 Manipulators
  • Probe Station
  • DC & HF/Microwave versions




    Double Sided Probing

    Both standard DSP for Emission Microscopy and SDSP (Simultaneous Double Sided Probing) for double sided devices



    Vacuum, Low Temperature & Crayo

    The SemiProbe manual cryogenic research station is built on a rugged powder coated steel frame with built in vibration isolation. This system is configurable for operation at a vacuum levels of either 10 -3, 10-4 or 10-6 torr (Depending upon pump system selection) and temperatures from 85K to 425K. Our standard system utilizes 4 externally controlled manipulators, however the  system is capable of mounting 6 manipulators if specified by the user. Probe tips on the manipulators are easily positioned and repositioned from outside the chamber during operation.



    Temperature control module
    Temperature Range: 85K to 425K
    Liquid Nitrogen Module
    Temperature Resolution: 0.1 degrees C


    Manual Probers

    probers have the wafer manually loaded, aligned and die to die movement is accomplished via manual hand controls


    Semiautomatic Probers


    PC/Software Driven

  • Wafer is manually loaded
  • Software “Wizard” walks operator thru 2-point alignment
  • Die index set
  • Prober automatically steps die to die until completed
  • Repeat process again

    Fully Automatic Probers

    Load a cassette, initiate system and automatically

  • Loads wafer (MH)
  • Aligns wafer (PR)
  • Probes wafer
  • Returns wafer to cassette and loads next wafer
  • Wafers
  • Diced die in waffle packs
  • Diced die on stretch frame

    Single Die, Packaged Parts, Wafers/Substrates – 50 mm, 75 mm, 100 mm,   125 mm, 150 mm, 200 mm, 300 mm and larger


    Magnetic Stimulation System

    Controlled application of a magnetic force within 3 mm of the DUT.  Controlled in:

  • Magnet X, Y, Z, & theta
  • Stage X-Y, Z & theta
  • Microscope X,Y, and Z


    LEC – Localized Environmental Chamber

    Testing below the dew point requires a controlled dry atmosphere around the thermal system, probes and DUT (device under test).


    AVP – Automatic Vacuum Prober

    A fully Automatic vacuum probing system

  • Load locks for in and out bound wafer cassettes
  • modular to allow easy expansion
  • High Volume
  • High Thru put
