The CMS experiment at the LHC will comprise a large silicon strip tracker.
This article highlights some of the results obtained in the R&D studies for
the optimization of its silicon sensors. Measurements of the capacitances
and of the high voltage stability of the devices are presented before and a
fter irradiation to the dose expected after the full lifetime of the tracke
