Sputtering of TiW

Deposition of TiW alloy can be done in the Wordentec. If necessary, processes may also be developed for depositing TiW in the Lesker sputter setups (contact responsible staff for this).

-'''Deposited rates'''
-This is done by a sputtering process. Process parameters (argon pressure and effect) can be varied, the surface roughness and the deposition rate (see [[/Sputtering of TiW in Wordentec|here]]) and may change with these settings.
-'''Deposited film characteristics'''
-AFM pictures show how the surface roughness is dependent of the process parameters, this can be seen here.
