Work Activities
Optical metrology is a key ingredient of nanolithography, as it enables the characterization of critical features of nanostructures printed on wafers. High-resolution imaging is an essential part of optical metrology: We need to perform fast imaging with the highest spatial resolution through a simple and compact imaging probe.

Computational imaging is a promising new approach for microscopy, as it has the potential to increase the performance of any imaging system beyond the limitations introduced by optical components. Compressive multimode fiber imaging is a novel imaging paradigm that uses a hair-thin multimode fiber and the fact that natural images are sparse on some basis to recover sub-wavelength information.

As a PhD student, you will develop new approaches to sparsity-based subwavelength imaging through optical fibers. New techniques will connect several modern and dynamic research areas that are still unconnected to date: computational imaging, complex wavefront shaping, compressive sensing and metrology. This will enable fast and accurate characterization of 3D multi-layer nanostructures and pave the way for better metrology tools for tomorrow’s nanolithography.

Qualifications
You have (or soon will have) a MSc physics or applied physics. Knowledge of (computational) microscopy, experimental optics, and/or semiconductor metrology is advantageous. Programming skills (Python or Matlab) are welcomed. Good verbal and written communication skills (in English) are required.

Work environment
ARCNL performs fundamental research, focusing on the physics and chemistry involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. While the academic setting and research style are geared towards establishing scientific excellence, the topics in ARCNL’s research program are intimately connected with the interests of the industrial partner ASML. The institute is located at Amsterdam Science Park and currently employs about 100 persons of which 65 are ambitious (young) researchers from all over the globe. www.arcnl.nl

Working conditions
The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of four years, with a starting salary of gross € 2,781 per month and a range of employment benefits. After successful completion of the PhD research a PhD degree will be granted at a Dutch University. Several courses are offered, specially developed for PhD-students. ARCNL assists any new foreign PhD-student with housing and visa applications and compensates their transport costs and furnishing expenses.
