• 5 from 6 sensors improved, but…– they needed ~20 min or longer to reach the

specified limit!– each sensor has a few „high leaky“ strips! – Σ leaky strips ~ IV ( few strips drive IV)

– EACH leaky strip is scratched !

Attention: standard test with “I-t” would had have jected 6 instead of 1

• Clear correlation between IV and leaky strips and scratches on sensors observed!

• No IV-breaks on Minisensors ! Handling !

Pinholes should be here !

Effect is located in the Al layer, above the oxide!


Summary of scratch-testSummary of scratch-test• Scratches increase individual strip leakage current• Some few leaky strips drive high IV• “Hard” mechanical force necessary to damage sensor! • ALL unscratched minisensors show GOOD IV !• ALL leaky strips are scratched, but not all scratched strips

are leaky !• Pinholes???

– no pinholes produced in scratch-test– no big differences between data of ST and QTC (w.r.t. pinholes)

Effect is located in the Al layer, not the p+ layer

CMS sensors have metal strip overhang!!!!


HPK W1TID qualificationHPK W1TID qualification

• PQC fine, but quite low depletion voltages

• BTC OK

• Masks: postponed -- should be done in Vienna, cause CMM breakdown in KA

• QTC: fine, but quite low depletion voltages!– Very low total leakage currents. – 3/27 sensors measured (no single strip failure)
