Electronics on plastic using embossing technology

At TNO, Patterning for Flexible Systems

Internship description:

Current electronic devices are made on rigid silicon wafers. The processes are batch wise, and use all kind of vacuum deposition and cleaning techniques for making conductive lines. To make flexible electronics like bendable displays, smart packaging, OLEDs, or solarcells, electronics must be made by other processes like Roll 2 Roll printing processing. For patterning of metal lines we propose to manufacture metal grids into the plastic foils by use of embossing.

The goal is to investigate the embedding into a coating layer on the foil, by optimizing the metal grids, coating, a templates. This can be used in OLEDS or conductive lines for transistors.

Your tasks and responsibilities include:

• Literature research to provide you with the required theoretical background about imprint lithography and embossing techniques

• P erform experiments in laboratory and cleanroom (substrate preparation, pattering, development)

• Measure results of the metal grids.

• Fine tune process parameters and make a demonstrator

• Participate in group meetings, provide feed-back, discuss results, and propose solutions to various challenging aspects

• write experimental reports

Profile:
You are an ambitious master student with both scientific and practical skills. You have a material engineering, chemical engineering, or applied science background. You have good communication skills in English and you are independent but also a team player.
