ABC130 Wafer Probe
Peter W Phillips12/03/2014
ABC130 Wafer Probe• Three projects competing for time on RAL Cascade S3000 probe station
– Try older Micromanipulator station instead• Originally bought for “The Red Experiment”, but little used• Still seems to work
• First connected the probe card on Friday– Took a while to get good probe contact– Then had to find and correct two silly mistakes
• Peter’s omission of jumper on ABC130 driver• Vendor’s zero ohm SLVS terminations on probe card (!!)
– Working as of today (12th March)
• Proposal is to run MUX scans only– Should be sufficient to identify gross failures– Should also confirm FIB success

Outlook
1. Screen the NanoScope FIBbed die tomorrow– Manual loading, one die at a time
2. Screen the three wafers later this month– Probably after ACES– Requires a little more code development to run
automatically
