What you will do: One key aspect explaining the success of smartphones are their low‐profile integrated optical devices (cameras and displays) that rely on micro‐and nanostructures for optimal performance while minimizing their bulkiness. Many formerly voluminous elements as lenses, mirrors or diffractive optical elements can be replicated by profiling the surface of a submicron thin film using techniques compatible with the microelectronic industry. These flat optical components achieve the same functionality than the bulkier counterpart but their integration on top of imager circuits is greatly simplified. In the upcoming project, we are developing a range of low‐loss, optically thin devices based on metasurfaces to efficiently shape light beams. The nanofabrication of antenna and resonator arrays will be performed using imec's unique expertise in advanced lithography techniques and thin film deposition and etch. A key enabler for the replication of nanophotonic components is nanoimprint lithography. This technique allies high‐resolution with high‐throughput and low‐cost, and is therefore particularly attractive for the fabrication of optical components at industrial scale. The realization of metasurfaces by nanoimprint lithography, however, poses a number of challenges in terms of materials and integration such as the development of high index resins, the removal of residual layer or the use of the resist as an etch mask for metal patterning. In this work, you use your background in optics and in nanoimprint technology to fabricate miniaturized and flat optical systems. You participate in the conception and the design of the nanoimprinted pattern and evaluate the electrical and optical properties of the devices. You can rely on a wide range of processing and analysis tools in our state‐of‐the‐art 200mm and 300mm cleanroom facilities and associated laboratories. Furthermore, you have the chance to work on the latest line of nanoimprint lithography machines to bring your academic background to the next level in technology development.
What we do for you: You are going to join an interdisciplinary and multicultural team of highly skilled scientists and engineers that work at the forefront of research. We offer you the opportunity to make your next career step by working in one of the world's premier research centers in nanotechnology at its headquarters in Leuven, Belgium. We are going to thoroughly train you at the start of your job and you will get access to advanced processing tools and modules within our state‐of‐the‐art cleanroom environment. You have a chance to expand your understanding of optical system design on the nanometer scale.
Who you are: We are looking for a candidate with a background in nanoimprint technology. A good understanding of the related material properties and processing concepts is essential while, experience in micro/nano‐optics is a plus. You are highly motivated, willing to tackle the challenges of bringing nanoimprint technology to the next level. You have a PhD degree in material science, physics, nanotechnology, or equivalent.We are looking for your knowledge in nanoimprint technology in combination with your systematic process development skills.Know-how of optics in design and analysis is a plus.We appreciate your initiative and independent work attitude, while being part of a team. You can also guide and motivate team members in their work.You are creative and liketo think with the team to solve problems.We value your drive for results and ability to meet stringent deadlines with quality output.You are flexible to accept new challenges in the future, and to evolve together with the changing R&D demands of our high‐tech environment. The imec environment requires a good team player with competent communication and reporting skills. Given the international character of imec, knowledge of English is mandatory.Please note that this project is in the framework of CSC-IMEC-KU Leuven Scholarships.
