  The present generation of Micro-Pattern Gaseous Detectors (MPGDs) are
radiation hard detectors, capable of detecting efficiently particle rates of
several MHz/cm$^2$ , while exhibiting good spatial resolution ($\leq$ 50
$\mu$m) and modest time resolution of 5-10 ns, which satisfies the current
generation of experiments (High Luminosity LHC upgrades of CMS and ATLAS) but
it is not sufficient for bunch crossing identification of fast timing systems
at FCC- hh. Thanks to the application of thin resistive films such as
Diamond-Like Carbon (DLC) a new detector concept was conceived: Fast Timing
MPGD (FTM). In the FTM the drift volume of the detector has been divided in
several layers each with their own amplification structure. The use of
resistive electrodes makes the entire structure transparent for electrical
signals. After some first initial encouraging results, progress has been slowed
down due to problems with the wet-etching of DLC-coated polyimide foils. To
solve these problems a more in-depth knowledge of the internal stress of the
DLC together with the DLC-polyimide adhesion is required. We will report on the
production of DLC films produced in Italy with Ion Beam Sputtering and Pulsed
Laser Deposition, where we are searching to improve the adhesion of the thin
DLC films, combined with a very high uniformity of the resistivity values.
