PhD Next generation multi-beam technology for high-throughput inspection

Research / Academic

Within a large European consortium, TU Delft is collaborating with industrial partners to develop new instrumentation for high-throughput nanoscale imaging. Electron beam technology is essential as an electron beam can be focused to a nanometer resolution probe that scans the sample to generate an image. However, scanning a single electron beam in nanometer-scale steps over a macroscopic sample is too slow for relevant applications, such as wafer inspection in the semiconductor industry or for imaging biomedical tissue in pathology. Scanning with multiple beams in parallel can tremendously increase throughput enabling revolutionary new possibilities for nanoscale microscopy. At TU Delft, several multi-beam (>50 parallel beams) electron microscopes have been invented and are being adopted for commercial use with industrial partners. We are now looking for a PhD candidate to work on the further technological development and industrial adaptation of our multi-beam microscopes. Work includes adopting the system to operate with more beams, higher (<5nm) resolution by controlling aberrations, and further developing detector technology, including towards multi-modal technology.


The successful candidate has a MSc degree in (applied) physics, is a skilful experimentalist, and has an interest in microscopy and/or electron optics. She/he likes to work in an international, multi-disciplinary environment on industrially relevant technological problems, and easily communicates and collaborates with partners from industry and (biomedical) end users.

Salary Benefits:
