Tool #445 ALD – Oxford FlexAl
The Oxford FlexAl Atomic Layer Deposition system is your tool-of-choice for slow, thin film growth of a limited selection of materials.
This tool can operate in two modes: Thermal ALD and Plasma ALD
Note that the film growth literally is atomic layer-by-layer, where each cycle includes switching of gas and onset of plasma. Therefore the maximum allowed film thickness is ~100nm.
