What is offered: A highly industry relevant master
project in collaboration with Ibsen Photonics A/S and DFM A/S. Your role will
be to assist with the development of an optical measurement system and test it
extensively in grating production at Ibsen Photonics.
About the project: The measurement system suggested is based on scatterometry. In
scatterometry the structure of a diffraction grating is reconstructed by
comparing the light scattered from the grating with computer simulations. This
technique is very fast and non-destructive - both abilities are desirable for
testing at the production line. Scatterometry is already a well-established
technology within the semi-conductor industry and sold by by big companies such
as KLA-Tencor and ASML. DFM has demonstrated that the technology can be used to
measure nanostructures in a wide range of materials used in the optical and
injection molding industry. The project will evaluate the scatterometry
technology as a tool for quality control of the gratings produced by Ibsen
Photonics. During the project you will be working with both experienced and
newly graduated researchers as well as industrial engineers and technicians. You
will be able to apply your knowledge from the university directly in an
What is expected: An eager and capable master student
ready to get hands-on experience from the industrial sector. Experience with experimental physics, simulation
and optimization, optics and programming will be helpful, but are not a strict requirement.
About Ibsen Photonics: Ever since being established in 1991,
Ibsen Photonics has been the leader in fused silica transmission gratings with
main products today including phase mask, telecom gratings, pulse compression
gratings and spectrometer gratings.
About DFM A/S: DFM (Dansk Fundamental Metrologi) is
the national Metrology institute of Denmark. DFM develops and provides
calibration services at the highest accuracy level in Denmark for a range of
metrology areas. DFM has over a decade of experience with scatterometry for
dimensional measurements at the nanoscale and is actively refining it to fit
new industrial sectors.
