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.
