Packaging and interconnects

Oral

Conventional bumping processes use electroplating for under bump metallization (UBM) and solder deposition. This process is laborious, involves time consuming photolithography, can only be performed using whole wafers and is therefore expensive in low volumes. In the low-cost development work, electroless deposition of UBM and novel solder ball placement techniques are studied as substitutes...

109. Design and Performance of Serial Powered Single-Sided Modules within an Integrated Stave Assembly for the ATLAS Tracker Barrel Upgrade

Packaging and interconnects

Oral

The design and performance of prototype single-sided modules with ABCN-25 front-end chips and 10x10 cm2 Hamamatsu silicon strip sensors is presented. A low mass module assembly has been achieved by gluing a single-sided flex circuit, with read out chips, directly onto the sensor. The design exploits the embedded shunt regulation within the ABCN-25 providing for a distributed and scalable...

28. SLID-ICV interconnection technology for the ATLAS pixel upgrade at SLHC

Packaging and interconnects

Oral

The on-going production of a demonstrator module for the ATLAS pixel detector upgrade is presented, exploiting thin planar pixel sensors as well as vertical integration technologies developed at the Fraunhofer Institute –IZM in Munich. The Solid-Liquid-InterDiffusion (SLID) technique is employed as an alternative to the bump-bonding process, to connect thin pixel sensors to the ATLAS FE-I3...
