Liverpool 1

  • two versions designed by Ilya Tsurin; 4 each produced (£123.00 including delivery and VAT):

Version 1: single layer Version 2: vias to sensor backplane for better heat transfer
DUT CTE board V1.png DUT CTE board V2.png
PCB Version 1 PCB Version 2

PCB-V2.jpg

PCB-V2.jpg: Populated PCB (V2.0)

DESY

Designed at DESY for the measurements of diodes and strip sensors.

Liverpool 2

Designed at Liverpool by Samuel Powell for measuring HV-CMOS sensors. The PCB fits the particulars cold chuck mount.

Mechanical changes to setup

For edge TCT measurements a 90 degree angle mount was designed, which allows to mount the cold chuck so that the laser hits the sensor edge. Because of the additional height difference to the laser line, a base plate for lifting the laser was designed as well. This plate has to be placed under the motion stage plate for the laser optics and should be screwed to the bottom of the box. The angle mount can be screwed to the motion stage instead of the '3UBP - Universal Base Plate'



Required equipment

Chiller

  • should be USB controllable
  • -40C ... ~+40C

  • Liverpool Clean room (other set-ups)
    • Thermo NESLAB RTE 740
    • Julabo F32
  • CERN
    • Huber CC 505
    • Huber Unichiller

Cold Block

Mounting Plane screwed to cold block with Peltier inbetween.

Nylon screw for cold block connection better than metal screw; use Screw Insulator to isolate screw from aluminium (necessary for metal screw).

Cables / Connectors

Sensor polishing

  • 2 bars to hold sensor during polishing process (CERN: teflon); bar width: 2 cm to clamp sensors which are larger than 1 cm. Use old silicon as distance holder (glued with Kapton inbetween bars).
  • cotton bud (for polishing)
