    AOW 2003 Prague - SCT Report

  • SCT silicon sensors procurementProduction & acceptance testing of the silicon sensors is ~ completeQuality of the detectors is excellentAll quantities within specificationHamamatsu barrel detector summaryVery low leakage currentsTypically 99.9% good readout strips

    CIS detectors: some IV problems

    0.2 mA# defects

    AOW 2003 Prague - SCT Report

  • SCT ASIC procurement Post irradiation studies indicate 10years lifetime @ LHCProduction stopped by ATMELUse ASICs with 1 ch. out of specs wherever reasonable (possible): qualification, rework, etc.

    Wafers delivered1053Wafers accepted (Yield >10%)798Yield of the accepted wafers is26%Fraction of wafers rejected24%Number of die accepted53K% of total requirement (61.5K)~86%Die with 1 channel out of spec~24%

    Production goal is to complete by Apr 04 with a yield > 90%

    AOW 2003 Prague - SCT Report

  • SCT Barrel baseboard & hybrid productionProduction rate is under control (recently stalled, but recovered)

    AOW 2003 Prague - SCT Report

  • SCT Barrel module assembly

    Note : Backup slide on s-curvesCritical issues:Get all clusters into productionProduction yield > 90%

    AOW 2003 Prague - SCT Report

  • SCT Barrel OptoharnessesOpto-harnesses are in productionBarrel LM tape production completeFirst 2 batches of 8 harnesses each for Barrel-3 evaluatedStart-up delay was caused by ESD damage to DORIC ASIC & other production issuesStart of production recommended

    Schedule can be recovered (complete production by the end of 2003)
