The semiconductor is the largest and longest established industry sector using PVD technology.
At its inception the sector used evaporative techniques to form the layers, but quickly adopted sputter-based solutions due to its inherent controllability. This sector has traditionally used either a 'cluster-tool' or an 'inline' approach. Both methods are still widely used and they are differentiated simply by whether the wafer is static during coating (cluster tool), or moves past the magnetrons during coating (in-line).
Cluster tool solutions are widespead with over 50 commercial offerings on the market.
Gencoa's circular magnetrons offer very good options for the semiconductor market.
- 3G Circular Magnetrons have a small footprint and with the ±45° angle adjustment, cluster tools can be easily set up
- Circular FFE for any wafer size available, up to 600mm target diameter
- 12" FFE for 8" wafers with an uniformity of 1-3 %
- High target use perfect for precious target materials
- High uniformity with small target substrate separation
- Reactive SiO2, Al2O3, SiN processes can be sputtered
- Speedflo reactive flow controller for perfectly controlled reactive processes
- Optix for process optimization, pump down time reduction, process knowledge
