Plasma Technology  

Dr Fuchs uses his Ionfab 300 for ion beam etching
and deposition. The system is configured with a
filamentfree 15 cm etch source and a 3 cm source
for deposition.

The photo and graph show the Ionfab 300 Plus
with RF sources, which has replaced the Ionfab 300
installed in Jena.

Process steps (with ion beam technology):
(a) Cr ion beam deposition
(b) ion beam etching of the Cr mask
(c) RIBE of quartz
