SIFREN 46: A NEW ENABLING MOLECULE
FOR THE SEMICONDUCTOR INDUSTRY
HIGH QUALITY
IN HIGH DEMAND
SolvayInnovationTrophy2006
The semi-conductor market was calling out
for a gas for the extra-fine and precise
etching of the plasmas present in particular
in memories. However, any product
developed had to meet stringent
environmental requirements. Hence the idea
of gaining a foothold on this market with
Sifren, a gas obtained from our Fluorine gas
technology. This is the best solution to meet
the critical demands of plasma etching.
Furthermore, it is an ecological compound
that has a short lifetime in the atmosphere,
a negligible global warming potential and
which is inert with regard to the
stratospheric ozone layer. The difference
in comparison with other gases is, in this
respect, decisive. Sifren has a unique
personality thanks to the ratio between
carbon atoms and fluorine, which gives it the
crucial capacity for optimal etching conduct
while at the same time forming a polymer
protective layer. The photoresistance
efficiency and selectivity is also very high.
The growing demand for Sifren 46,
particularly on the Asian market, will be
satisfied by the doubling of its production
capacity between now and 2010.

PARTNERSHIP WITH CUSTOMER, TO DEVELOP
OPTIMIZED FLUE GAS CLEANING AND RESIDUES
TREATMENT FOR GLASS INDUSTRY
IMPROVING FLUE GAS
DESULPHURIZATION
IN THE GLASS INDUSTRY
The regulations in the field of the cleaning
of gaseous effluents in the glass industry
are still relatively lax. But this situation
is changing and the gas desulphurization
in becoming major concern for this industry.
In view of the announced stricter standards,
the NEUTREC ® team initiated collaboration
with a reputed glass manufacturer.
Combining from the start, the knowledge
of the glass producer specificities, our
competencies in gas cleaning and the
possibilities Solvay products offer, should
allow the development of an original and
fully optimized desulphurization solution.
In line with the philosophy of previous
NEUTREC ® developments, the solution should
also include the treatment of the depuration
residues. Essentially technical, the project
was launched in February 2006 and it should
be possible to draw the first conclusions
at the end of the year.
A good positioning in this potential market
of industrial gas desulphurization ought to
lead to a significant growth of the NEUTREC ®
present applications.
