Success Story – MEMS Prober System - Taiwan

Written by Denis Place | July 28, 2021

SemiProbe provided a turnkey and Integrated 200 mm Semiautomatic MEMS Probe System with an Olympus Metallurgical Microscope for a large Wafer Foundry.

Customer Requirements for their MEMS Wafer Prober System:

  • Complete turnkey and integrated  MEMS wafer probing system to test up to 200 mm microfluidic MEMS wafers over temperature
  • Integrated solution had to provide a fully functional MEMS wafer probing and high magnification inspection capabilities using one platform
  • Programmable Manipulators for electrical testing and fluidic dispense
  • The devices needed to be heated and monitored from ambient to > 300 degrees. 
  • All test instrumentation, cables, connectors, and a Graphical User Interface (GUI) had to be provided

SemiProbe Solution:

Whole MEMS wafers, partial MEMS wafers, and individual die can be probed on the system using manipulators or a probe card. The devices are inserted in customized carriers and are held in place via a vacuum. The devices can be loaded on an adjacent bench or table and are easily inserted into and removed from the chuck assembly.
