Test of first 3D wafers Two wafers de 3D assemblies arrived CPPM September 2011. Third wafer was diced into chips. Problems with uniformity of the thinning of the upper tier: 15-20% of the wafer surface is defective. Measurements of the resistance of daisy chains and power pads have shown the short circuits between copper surface contacts between two tiers. Few chips without shorts selected. They works, but no communication between tiers established. Problem identified by Tezzaron to be bad wafer alignment at new production facility at Tempe(AZ). The same alignment problem probably creates weak adhesion and non-uniformities during thinning. Next batch of wafers will bonds at facility at Austria in November 2011 with final delivery in spring 2012. Paris-LPNHE 10.10.12 ATLAS pixel
