Tungsten (W) can be deposited by e-beam evaporation and sputtering. However, in case of evaporation the precess generates a lot of heat (despite water cooling), and this means the pressure rises as the chamber is baking out. It is therefore not easy to deposit films much thicker than 50-60 nm. Sputtering can be used without any particular issues. In the chart below you can compare the deposition equipment.
