New Progress • MS – JTAG loading problem appears to be solved. • Investigation of Phase-2 internal mis-synchronization is still under way. • Initial yield for thinned Phase-2 sensors. • Successful PXL sensor and RDO review.

Phase-2 Thinned Sensor Yield Visual Inspection of all Sensors Probe testing results for 18 Sensors wafer # B75041W05PE2 (pre-scribe and wafer thinning) 11 sensors – all working 3 sensors – 1 column bad 1 sensor – 3 columns bad LBNL-IPHC Phone Conference 07/15/2010
05/17/2010 Phone Conference - Homework Latch-up testing schedule Mimosa-26 and LUTS • We plan to test locally at the 88” cyclotron. • If we receive documentation and parts in July we can have preliminary results in September. Tests on the memory structure would have a similar delay. • Initially latch-up will be the primary focus, we will follow with SEU testing. • This testing will be part of planned effort for all ladder components. A draft LU and SEU plan for this testing may be found here http://rnc.lbl.gov/hft/hardware/docs/latchup/Latchup_plans_2010_(draft).doc LBNL-IPHC Phone Conference 07/15/2010
05/17/2010 Phone Conference - Homework Butting of sensors Question – does butting require a new mask? Or is the reticle placement on a wafer a step and repeat operation? • We wish to first assess the yield so the first prototype run masks should be optimized for the standard individual sensor arrangement. • Our plan would be to assess yield and then, if the economics of the reduced handling and ease of assembly make sense, pay for masks with a butted arrangement. By that time we should have a more well developed understanding of the logistics of full ladder assembly. LBNL-IPHC Phone Conference 07/15/2010
05/17/2010 Phone Conference - Homework Ultimate Design Review and Submission • Some constraints – • CD-2/3 estimated for November timeframe • Desire from last meeting to delay for ~ 2 months? • Propose early December review and mid-late February 2011 submission. See CD-1 preliminary schedule next slide. • Does this make sense from the IPHC viewpoint? LBNL-IPHC Phone Conference 07/15/2010
05/17/2010 Phone Conference - Homework Next Face to Face Meeting • It makes sense for us to have this meeting when we have some results to report on both the 10 sensor ladder test and perhaps the latch up testing. This suggests the post-September timeframe. • The constraints for CD-2/3 availability still remain. • Should we schedule this for the October timeframe or try to combine it with a Ultimate design review?

05/17/2010 Phone Conference Additional items • SUZE code to implement a Phase-2 based but Ultimate like data readout system. Desired but not required for current testing. • Ultimate – can we make the counter in the output register a JTAG defeatableparamenter? LBNL-IPHC Phone Conference 07/15/2010
Ultimate Sensor question How do we get a repeated pattern to allow for IODelay setting? Do we need a output register post SUZE? LBNL-IPHC Phone Conference 07/15/2010
