NWO announced that twelve consortia can start research projects through the Perspectief program. A crucial factor in these projects is their societal and economic impact. One of these projects is the CHAIN consortium, with AMOLF group leader Femius Koenderink as co-applicant. In this consortium, researchers join forces to advance the semiconductor industry. The budget will support six junior researchers in total, including one at AMOLF in the Resonant Nanophotonics group.

Project goal

Semiconductor chips are an important pillar of Dutch industry. New imaging and inspection techniques are needed to make these chips smaller, more powerful, more energy efficient, and less harmful to the environment. These techniques must be capable of producing high precision, high resolution and highly efficient three-dimensional images of the smallest possible structures.

The CHAIN consortium will develop new techniques based on light, extreme ultraviolet radiation and electron beams. By combining new measurement techniques with advanced data processing, the researchers aim to make imaging faster and more accurate. This will enable more precise control of production processes.

CHAIN participants

The CHAIN consortium is led by Stefan Witte from TU Delft and brings together expertise in optical microscopy, electron microscopy and algorithms from TU Delft, AMOLF, ARCNL, Utrecht University and Leiden University.

AMOLF contribution

The AMOLF researcher will develop theoretical and experimental techniques to reconstruct object images that are buried in complex environments that scatter light. The goal is to extract super high-resolution information from these buried features. Femius Koenderink says: “I am really excited about this project. We are going to bring together very complementary expertise, both from the point of view of physical imaging modalities and from the algorithmic point of view.”

Femius already works closely with ARCNL in a joint research program, and he expects that the researchers in this program will indirectly benefit from CHAIN, for instance through the incorporation of state-of-the-art mathematical methods.

Finally, Femius is looking forward to collaborating with the associated companies. “It will be a unique opportunity to learn from domain experts in the associated companies, both regarding the problems that they struggle with and the wonderful methods that they develop to tackle them.”
