Offer Description

The growing demand for electronic devices in our society requires the production of billions of chips annually. Part of the production process is the accurate handling and placement of micro-chips in packages for protection and electrical connection. In order to keep up with the increasing market demand and the required reduction of cost and environmental impact, chip assembly must become faster, more accurate and more sustainable. This requires radically new assembly concepts and processes.

We develop innovative micro-chip assembly processes in which we exploit microdroplet technology for non-contact chip handling, placement and alignment. Technical challenges include the small size of chips to be handled and assembled (<100 micrometer), high precision and high throughput. This vacancy is part of a large collaborative project with a leading Dutch chip assembly company.

The aim of this Postdoc position is to research the basic physics of high-speed chip handling using micro-droplets. Based on fundamental understanding, new assembly processes will be developed, e.g. for micro-chip entrapment on droplets, chip handling, chip placement and chip alignment. During the assembly process, the chips will pass transitions, e.g. from hard-contact state to soft-contact state and the other way around. Investigating the physics related to these transitions is an important aspect of the research.

The research will be based on experimentation, supported by numerical and/or analytical modelling. We expect that the research will lead to experimental setups, in which new assembly processes are explored and characterized. Maximizing assembly process throughput, robustness and yield are the key performance criteria.

There are ample opportunities for generating publications in diverse scientific and engineering fields. Our eventual target is to create the knowledge and guidelines for the company to develop new industrial technologies and implement these in new generations of machines. The research is clearly linked to real industrial demands, and you will explore the integration of the gained knowledge into industrially viable chip assembly processes and machines.

The project provides a unique learning opportunity through the collaboration in a large, multi-disciplinary team and the immediate industrial relevance of the research. You will be part of a team of 5 PhD and 3 Postdoc researchers, who work together with scientists from TU Delft and experts from the R&D team of the company involved. Each of the researchers work on a dedicated part of the project, while at the same time closely collaborating with the rest of the team to ensure all parts will eventually fit together.

Specific Requirements

We are looking for candidates who recognize themselves in one or more of the following:

  • You have a PhD degree in micro & nano engineering, (applied) physics, dynamics, mechanical / mechatronic engineering, or another field of work relevant to the topic of research.
  • You have knowledge on and expertise in micro-fluidics, fluid dynamics, fluid-structure interactions or similar topics. Microfluidic effects play a significant role in the research and having knowledge on this will be an important criterion in candidate selection.
  • You like to combine experimental work with analytical or numerical model development.
  • Having experience in design, realization and/or operation of experimental setups is another important criterion in candidate selection, e.g. use of actuators/motion systems, vision systems, sensor systems, optics or control (LabView or similar).
  • You are a team player who likes to collaborate with colleagues from university and industry.
  • You are enthusiastic to work on cool, ground-breaking technology with the aim to revolutionize future chip production methods. You are able to link research to industrial application.
