2. GridPix: Production and R&D
HvdG, Nikhef
GridPix Workshop, Jan 28, 2013
Nikhef

3. 2010: some good chips with 4” ‘chipsquare’ process
2010: Total failure GridPix SMC, Edinburgh
2010: IZM-1: problem Al deposit, some OK
2011: IZM-2: cavities in SRN potection layer
2012: IZM-3: some perfect chips, but many (new) problems
All individual steps, at IZM and MESA+, for 8” productions
have been successfully realised
After testbeam in November 2012, new problems occured

4. ATLAS Gossip/GridPix panel (2009):
“show, in three years: price, robustness, radiation hardness”
ATLAS/Nikhef Update program (request 5 MEuro)
includes LVL1 trigger
does NOT include Gossip for pixel Vertex detector
What can we do?
Inventarisation of problems
plan for IZM-4

5. R&D for next generation GridPix chips:
an all-ceramic GridPix
double discharge protection
homogeneous thermal expansion
no outgassing
