Abstract
CVD - tungsten thin films are deposited using different technological parameters. As-deposited films are rich of carbon, oxygen as well as of nitrogen. Partially annealed in H2 atmosphere, these films exhibit solar selective properties - high absorptance in the visible coupled with high reflectance in the IR. Fully annealed, the films are almost pure W with low resistivity, assuring good transport properties for the purposes of VLSI applications.
