Researchers develop self-assembling semiconductors with microwaves

Posted on Saturday, October 30 2010 @ 05:36:49 CEST by

Scientists at Canada's National Institute for Nanotechnology (NINT) have found a way to use microwaves to dramatically reduce the process time of self-assembling semiconductors:
Self assembly is seen as key to enabling nanotechnology, but until now the block co-polymer method, which directs nanomaterials to create moulds and then fills them in with a target material, was too slow to be useful.

However, the Canadian researchers found that by switching from old-fashioned convective cookers to newfangled microwave ovens the process time was reduced from days to less than a minute.

“By using microwaves, we have dramatically decreased the cooking time for a specific molecular self-assembly process used to assemble block co-polymers, and have now made it a viable alternative to the conventional lithography process for use in patterning semi-conductors,” the researchers said.
