Deposition of TiW alloy can take place in the Wordentec. Observe: right now we don´t have a TiW target for Wordentec, please contact thinfilm@danchip.dtu.dk if you are interested in depositing TiW.

	Sputter deposition (Wordentec)
Batch size	24x2" wafers or 6x4" wafers or 6x6" wafers
Pre-clean	RF Ar clean
Layer thickness	.
Allowed substrates	Silicon wafers Quartz wafers Pyrex wafers
Allowed materials	Silicon oxide Silicon (oxy)nitride Photoresist PMMA Mylar SU-8 Metals
Deposition rate	Depending on process parameters, see here.

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 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.
