This talk highlights recent breakthroughs in precision radiation detector technology developed at the Semiconductor Laboratory of the Max Planck Society. Pioneering advancements have enabled the production of ultra-high-quality, wafer-sized silicon detectors that meet the rigorous demands of various scientific fields, with a primary focus on creating unique, customized sensors unavailable on...
We are investigating the use of low temperature wafer-wafer bonding in the fabrication of next-generation particle pixel detectors. This bonding technique could enable the integration of fully processed CMOS readout wafers with high-Z absorber materials, facilitating the creation of highly efficient X-ray imaging detectors. It might also facilitate the integration of structures embedded inside...
Silicon Photomultipliers (SiPMs) offer exceptional photon detection sensitivity, but face challenges in maintaining linearity across their operational range. At low light levels, the primary effect is the non-linearity of gain resulting from the voltage dependence of pixel capacitance. At high light intensities, the finite pixel count leads to non-linear response, limiting the dynamic...
Silicon Photomultipliers (SiPMs) are single-photon sensitive detectors that continue to attract increasing interest in several industrial and scientific applications that require fast detection speed, high sensitivity, compactness, insensitivity to magnetic fields and low bias voltages. In particular, the SiPMs are used in high-energy physics (HEP) experiments, and for the readout of...
This work presents a packaging concept enabling planar and curved chip integration with a minimized material budget. Building on foundational techniques introduced two decades ago for the ALICE ITS1 and the STAR tracker, this approach uses flexible cables made of aluminum and polyimide. Additionally, instead of conventional wire bonding, which poses limitations in handling and bending of...
