VortexTMALD is a rotary batch technology that uses rotation of a disc or cylinder to transport substrates.
Several angstroms per second, which is faster than many oxide sputtering processes.
No coating anywhere in the chamber except on the substrates and carrier surface.
Precursors are consumed only on the substrate track – exhausted precursor material may be captured and re-used.
Low Temperature Processing
Leveraging the advantages of simple DC plasma, our processes are available at 100°C or lower, even down to room temperature.
...plus all the benefits of Conventional ALD!
VortexTM ALD can deliver five ALD cycles per second in its single-cycle configuration - and up to 20 when paired with PlasmaShield technology.
Greatly simplifies zone separation
Enables the use of a simple DC plasma
Eliminates the time required for precursor introduction, saturation, and purge
Our VortexTM ALD technology revolutionizes batch ALD processing.
Instead of pulsing and purging precursors from a static substrate in a single chamber, the substrate is transported by rotation to the various precursor and purge zones of the reactor.
This eliminates the time required for precursor introduction, saturation, and purge with each ALD cycle. Further, Lotus’ patented Radical Enabled ALD process, incorporating Precursor “Separation” by Radical Deactivation technology, greatly simplifies zone separation in the reactor, and enables the use of a simple DC plasma for PEALD processing.
For applications requiring even higher deposition rates, our PlasmaShield technology may be employed to enable up to 4 ALD cycles per revolution. This technology can be scaled from small reactors for research and small area manufacturing, to meter-scale substrates.
