3 Probestation

4 Error estimation 1000 measurement runs on one strip (ST teststructure) ParameterMean  MinMax Rpoly (M  ) 1,0640,001371.06051.0687 Leakage current (pA) 62,12,259,064,0 Coupling capacitance (pF) 108,30,78106,13108,57

5 Software – Front panel Testing time ~ 2h

6 Probing marks Hamamatsu Karlsruhe

7 Pick up tool

8 Packaging (Hamamatsu) Sensor Teststructures Sandwich packaging in envelope Bad to handle Optical inspection  HANDLING  against specification Takes time Air cusion effect while placing  gliding

9 Packaging 2 (ST) Optical inspection  very good Easy to take out All 4 TS available

10 Optical survey and dimensional measurements

11 Check Sheet:

12 Pictures 25  m

13 More pictures Scratchpad used RpolyAdd DC pad 3 AC pads

14 Electrical characterization of sensors Rpoly with 10VRpoly with 2V Changes in measurement with respect to specs

15 Electrical characterization of sensors Summary

16 Electrical characterization of sensors CV & IV

17 Electrical characterization of sensors Rpoly

18 Electrical characterization of sensors coupling capacitance

19 Electrical characterization of sensors leakage current

20 Comparison of our test results with industry results (based on 5 sensor of 8 ) IV even lower than company measurement CV perfect agreement Some Rpoly higher than company measurement (but company only measured 1 per batch or even TS only) No single strip fault (agreement) (neglect Rpoly)

21 Relevant problems Nothing Serious V depletion not calculated Improvements: Automatic web publishing (ready 50%) Implement Pattern recognition

22 Optical survey of ST prototype Pinhole or bad coupling capacity No strange electrical behavior

23 Optical survey of ST prototype 2 Z (  m) Bowl shape! Asymmetric cut! Global size OK!

24 Pads

25 Electrical Survey Very high total leakage current Depletion voltage fine One region (7 strip) with a very high leakage current Some coupling capacitors out of specs
