20th Conference on Gettering and Defect Engineering in Semiconductor Technology (GADEST 20/24)

The GADEST (Gettering and Defect Engineering in Semiconductor Technology) conference is devoted to semiconductor defect physics, materials science, and device technology and focuses on both fundamental as well as technological aspects of defects, growth, processing, and modelling of electronic materials and devices, ranging from microelectronics to photovoltaics.

Since 1985, the GADEST conference series provides a forum for experts in the field of semiconductor technology, semiconductor device physics, and defect physics. Focusing on applied research, an important goal of the GADEST is to bring together academics and industry. The spirit of the GADEST is to establish an atmosphere which allows for close discussions and interactions among participants.

At the GADEST 20/24, Fraunhofer IISB is involved by the conference chairs Prof. Johannes Heitmann and Dr. Franziska Beyer (together with Prof. Daniel Hiller from IAP, TU Freiberg), support of the conference organization, and by research presentations. We are looking forward to meeting you at the GADEST20 2024!
