Progressing pore shrink methods for enhanced membrane performance

Leuven | More than two weeks ago

There's plenty of room with bottom-up. Be part of creating imec's next generation life science devices.


Separating molecular species e.g., proteins, requires membrane pore channels that can be tailored to a specific dimension and/or surface chemistry. The objective of this work is to tune block copolymer membrane pores that are compatible with a semiconductor platform. Several routes are to be evaluated to shrink silicon oxide nanopores in the sub-10 nm regime at wafer scale. The candidate will contribute to pushing forward the application areas of porous and dense silicon membrane arrays for potential healthcare devices. The successful candidate will engage with and learn from collaborators at imec towards understanding and applying the latest semiconductor processing methods (i.e., lithography, etch, deposition and characterization).


Type of work:

15-20 % literature review, 70-75 % experimental work / data analysis, 10-15 % design of experiments.


Expected tasks:


  1. Investigate and evaluate potential process routes based on block copolymer lithography.
  2. Collaborate with researchers on thin film analysis using atomic force microscopy, scanning electron microscopy and surface measurements, e.g. contact angle, XPS etc.
  3. Image analysis of pore shrink methods after performing inorganic thin film deposition or thermal anneal protocols.
  4. Written reports and presentation of key findings at team meetings.
