Dedicated AS-ALD micro-reactor for FEBID nano-templates — •Peter Gruszka, Giorgia Di Prima, Roland Sachser, and Michael Huth — Goethe Universität, Max-von-Laue-Str. 1, 60438 Frankfurt am Main, Germany
In recent years, conventional methods of nano-structuring are slowly reaching their lower limits. A novel bottom-up approach emerged, which combines focused electron beam induced deposition(FEBID) and area-selective atomic layer deposition(AS-ALD). FEBID is a serial, bottom-up and direct-write technique yielding structures with superior lateral resolution (< 10 nm), but with poor material quality. In contrast, ALD and especially AS-ALD are parallel and bottom-up approaches with exceptional thickness control resulting in high purity sub-nano films.
We successfully performed the combined FEBID-ALD process in our Nova 600 Dual Beam scanning electron microscope. The ALD experiments were conducted on purified platinum FEBID-nanostructures which were monitored via in-situ conductance measurements. For further investigation and optimization, we built a dedicated AS-ALD micro-reactor.
