Description
The PSI technical platform at IJCLab has been created in 2021 to provide advanced testing and characterization means for semiconductor devices. It is equipped with a probe station, a digital microscope, a 3D metrology system, climate chambers and controlled-atmosphere storage cabinets, which are distributed across a 70 m² clean room and a test room. The platform is designed to support a wide range of activities, including electrical characterization (I-V, C-V, etc.), visual inspection, precision metrology, radioactive source testing and thermal cycling, both in R&D and production phases.
IJCLab plays a major role in the HL-LHC upgrade, leading the assembly and production of silicon modules for ATLAS/ITk, ATLAS/HGTD detectors, which includes the assembly of the module components and the electrical tests at many steps of the production sequence. After a successful R&D phase, an intensive production campaign is planned between 2025 and 2027, involving around 1200 modules for ITk-Pixel and 2000 modules for HGTD.
In parallel, ongoing R&D focuses on SiW-ECAL, developing a highly-segmented calorimeter with PIN diodes for a future Higgs factory, and on EIC-Roman Pots, advancing AC-LGAD sensors and the EICROC chip for high-precision tracking at the EIC. Current activities include sensor I-V testing and prototype validation with a beta source at PSI.
Looking forward, the PSI platform aims to expand its role as a shared infrastructure, opening to external institutional and industrial partners, and positioning itself as a key facility for the development of next-generation semiconductor detector technologies.
