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

First “Successful” Probe Test 15:10 GMT

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
