H ardware setup
Hardware setup

Probestation 1:6“(200mm * 300mm + 360° rotation + 15mm Z)QTC

Instruments: HP4274A (LCR), K6517 (electrometer) , HP6614C (voltage supply), K595 (quasistatic CVmeter)

Status: Operational (used to measure Hamamatsu)

Software (user friendly and some error protections)

Probestation 2:6“(200mm * 100mm + 15mm Z)IQC

Instruments: LCR, electrometer, voltage supply

Status: Operational

Misc: Homemade relay system (17 channels each)

Optical Inspction: Zeiss CMM (500*500*500) Res.: 1mm (Z~5mm)

Teststructures

Packaging (Hamamatsu)

Sandwich packaging in

envelope

  • Bad to handle

  • Optical inspection  HANDLING  against specification

  • Takes time

  • Air cusion effect while placing  gliding


Packaging 2 st
Packaging 2 (ST)

  • Optical inspection  very good

  • Easy to take out

  • All 4 TS available

Comparison of our test results with industr y results based on 5 sensor of 8
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)


Relevant problems
Relevant problems

  • Nothing Serious

  • Vdepletion not calculated

Improvements:

  • Automatic web publishing (ready 50%)

  • Implement Pattern recognition

Pinhole or

bad coupling capacity

No strange electrical behavior

Asymmetric cut!

Global size OK!

Z (mm)

Bowl shape!



Electrical survey
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
