Department for Semiconductor Detectors

The expertise of the department for Semiconductor Detectors is in the development of tracking and vertex detectors made of semiconducting materials. Such detectors are mainly implemented in large scale accelerator experiments at major research laboratories like CERN. The department was significantly involved in the design of the silicon vertex detector of the DEPLHI experiment at the LEP accelerator and in the All Silicon Inner Tracker at the CMS experiment at the recent LHC accelerator.

The current involvement is in the Silicon Vertex Detector of the Belle II experiment. An R&D focus is around an upcoming upgrade of the CMS Tracker for the HL-LHC and the next generation International Linear Collider.

The Know-How of the department covers the design (mask design) and the electrical and microscopic characterization of silicon sensors, the construction and wire bonding of detector modules and the test of such detector modules using in-house lab tests and beam tests.

Industrialization of the large-scale production of particle detectors for HEP applications

Since the active areas of the current and future silicon tracking devices become increasingly larger, the production process of the detectors must be commercialized. We are working since several years on this topic and collaboration with the semiconductor foundry Infineon for this purpose.

The following video (in German) presents this activities.
