GridPix: Production and R&D HvdG, Nikhef GridPix Workshop, Jan 28, 2013 Nikhef
2010: some good chips with 4”‘chipsquare’ process 2010: Total failure GridPix production @ 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
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
R&D for next generation GridPix chips: • an all-ceramic GridPix • double discharge protection • homogeneous thermal expansion • no outgassing
