Efficient data transmission from silicon wafer strip detectors

Test Bench for Silicon Strip Detectors Testing

During the next few months more than 400 Silicon Strip Detector (SSD) modules will be tested before and after their installation on the ladders and dispatch to Brookhaven National Laboratory. The requirements for the test bench have been defined and the architectural design of all software components has been completed. The system is distributed and features a client–server architecture. Measur...

Silicon strip detectors for ATLAS at the HL-LHC upgrade

The present ATLAS silicon strip tracker (SCT) and transition radiation tracker (TRT) are to be replaced with new silicon strip detectors as part of the inner tracker system (ITK) for the Phase-II upgrade of the Large Hadron Collider, HL-LHC. We have carried out intensive R&D programs based on n-on-p microstrip detectors to fabricate improved radiation hard strip detectors that can survive the r...

Transmission Laser Bonding of Glass with Silicon Wafer

As a microassembly and an encapsulation technique, wafer bonding offers a unique opportunity to combine different materials. Transmission laser bonding not only can satisfy wafer level bonding requirements, but can also be directly implemented into the existing automatic semiconductor fabrication line. In this paper, a laser-induced wafer bonding technique for micro-electro-mechanical systems (...

Hydrophobic silicon wafer bonding

Wafers prepared by an HF dip without a subsequent water rinse were bonded at room temperature and annealed at temperatures up to 1100 “C. Based on substantial differences between bonded hydrophilic and hydrophobic Si wafer pairs in the changes of the interface energy with respect to temperature, secondary ion mass spectrometry (SIMS) and transmission electron microscopy (TEM), we suggest that h...
