P. Frach et al., THE DOUBLE-RING MAGNETRON PROCESS MODULE - A TOOL FOR STATIONARY DEPOSITION OF METALS, INSULATORS AND REACTIVE SPUTTERED COMPOUNDS, Surface & coatings technology, 90(1-2), 1997, pp. 75-81
The double ring magnetron module has become a powerful tool for solvin
g a great variety of thin film deposition tasks in the field of statio
nary sputter deposition of substrates in the diameter range of 200 mm
at high deposition rates. Different variants of powering - DC, MF (50
kHz) and RF (13.56 MHz) - that allow to sputter conductive and insulat
ing materials will be compared. In reactive sputtering new solutions f
or magnetron design, reactive gas inlet, power input and control syste
ms will be reported, that guarantee during the target life time the st
able, reproducible and uniform deposition of materials like SiO2 or Al
2O3.
