Fully Automatic Wafer Prober - Success Story - MEMS

Customer Requirements:

The customer wanted to test 150 mm silicon MEMS wafers in a fully automatic mode under vacuum. The wafers would be mounted in a single cassette into a material handling chamber with a load lock. The material handling unit (MHU) would remove a wafer from the cassette and place it on a mechanically clamping chuck mounted on the probe system vacuum stage in the After alignment the device testing would be performed using a probe card or individual programmable manipulators with DC and High Frequency (HF) probe arms and probes.  Everything within the chamber would need to be vacuum compatible.
