The CMS phase-2 upgrade, necessary to cope with the radiation levels and pileup of the High-Luminosity LHC, requires a finer granularity, radiation-tolerant endcap calorimeter. This is achieved by 600 m^2 of silicon sensors as detector material for the highly radiated regions, together with scintillator tiles with individual SiPM readout. To reduce the cost, a new 8-inch wafer process is used, posing new challenges for prototyping and production.
This talk covers the prototyping of the 8-inch process for highly radiation tolerant, large-area, DC-coupled silicon sensors, together with tools for high-throughput, non-destructive characterization via a dedicated test structure system.
