Microwave oven key to self-assembly process meeting semi-conductor industry need
Date:10/25/2010

Thanks to a microwave oven, the fundamental nanotechnology process of self assembly may soon replace the lithographic processing use to make the ubiquitous semi-conductor chips. By using microwaves, researchers at Canada's National Institute for Nanotechnology (NINT) and the University of Alberta have dramatically decreased the cooking time for a specific molecular self-assembly process used to assemble block copolymers, and have now made it a viable alternative to the conventional lithography process for use in patterning semi-conductors. When the team of chemists and electrical engineering researchers replaced convective heat with a microwave oven, nano-sized particles were encouraged to organize themselves into very regular patterns extremely quickly reducing the processing time from days to less than one minute.

The processing time is very important if this self-assembly process is to be introduced to industrial semi-conductor fabrication. In the International Technology Roadmap for Semiconductors, the promise of self-assembly to address the need to put more and more functionality onto chips was recognized. The block co-polymer method, which directs nanomaterials to create molds and then fills them in with a target material, was known to be capable of creating very detailed patterns many times smaller than current technology. But previously the time needed for molecules to organize themselves was too long to be useful for the industry. The change of the heat source has brought that processing time well under the suggested target of 4 minutes.

"This is one of the first examples of the self-assembly process being used to address a real world problem for the semi-conductor industry," said Dr. Jillian Buriak "We've got the process; the next step is to exploit it to make something useful."
