1. US Module Production Quality
58 ST Sensor Modules
6 R5N, 33 R5S, 12 L12p, 7 L34
53 Grade A, 2 Grade F, 3 Irradiated
1 CMN module, 1 damaged by handling, 3 irradiated
0.28% Faulty Channels Per Module
134 HPK Sensor Modules
24 L34p, 26 L56p
132 Grade A, 2 Grade F
1 High bias current module, 1 module damaged in handling
0.06% Faulty Channels Per Module
All modules passed Vienna Box tests

2. Noise Studies
Differences in noise noticed for modules produced with ST/HPK and with different hybrid versions
No evidence of change of noise is observed in TOB1 modules
Dramatic decrease of noise in TOB2 STM (Version 4) compared to STM (Version 3)
HPK (Version 5) noise is slightly higher than in STM (Version 4)

3. TOB2: STM(H4) vs STM(H3)
Over 0.1 ADC noise decrease in ST modules when changing from hybrid version 3 to version 4
Modules all re-tested on the same stand to confirm difference

4. TOB2: HPK(H5) vs STM new (H4)
With newer hybrid versions, HPK modules have a slightly higher noise than ST module (~0.05 ADC in peak mode)
As the depletion layer is smaller in HPK than ST sensors, this increase in noise is not unexpected

5. LT Data Processing Outline
LT Thermal Cycle
Root File
XML File
Defect Analyzer
Root File
LT Macro
Summary Plots
Text File with Summarized Results
XML File
lt.pl script

6. Defect Analyzer
Parses root file output from LT and creates an xml file with the data in format needed for uploading to database
Bad channels are determined by applying cuts on each test performed
Noise: Relative cuts are currently being used
Due to slight change in average noise between First, Cold, and Last tests
Peak Time: Absolute cuts are currently being used
Pulse Height: Percentage cuts are currently being used

7. LT Macro
Analyzes root files and creates plots for each test on a channel basis as well as summary files with a list of channel flags in each test mode.

8. lt.pl Script Modifications
Identifies bad runs and makes comparison to ARCS database entry
Much progress made over last few months
Finalized cuts on the average value of each APV for CMN, Noise, and Peak Time
Used as an absolute check against tests that use relative or percentage cutting methods (Noise, Pulse Height)
The program now lists channel flags in ARCS, and channel flags in each temperature mode in LT (First, Cold, Last)
Used to find discrepancies between channel flags in LT and ARCS
Appends list of modules tested with Good/Bad flag to a summary.log file
Used for automating qualification of production modules

9. Work to Be Done for LT Cut Values for Defect Analyzer must be tuned
Final cuts are being set
Waiting for more data
False flags listed in xml files must be corrected
Can be done manually after the data has been reviewed by modifying the xml file (very tedious)
Flagging algorithm can be modified to reduced false flag rate
False flags can be ignored and uploaded into database
Rate of false flags small, but noticable (X/module)
