==Grains in a sputtered TiW film== | |||
TiW films were deposited by sputtering in the Wordentec. AFM pictures show how the surface roughness is dependent on the process parameters. | |||
For the sputter process, the power and argon pressure can be set to different values. Depending on the process parameters, the deposited layers will have different characteristics: the roughness, grain size and uniformity may be different. | |||
'''Power 150 W, pressure 1*10<sup>-3</sup> mbar''' | |||
With use of the settings 150W and 1*10<sup>-3</sup> mbar, a surface with low roughness is deposited. | |||
