Abstract: A target for sputtering, use of the target and method of manufacture of the target is provided. The target has a single piece target material for sputter deposition, with at least 1 mm thickness of material for sputtering, having a lamellar structure and comprising a metal oxide with at least 50 wt. % or more of tungsten oxide. The atomic ratio of oxygen over tungsten results in a compound with oxygen deficiency with respect to the stoichiometric tungsten oxide. The method includes spraying metallic tungsten and/or tungsten oxide powder in amounts so as to provide a layer of material for sputtering being at least 1 mm thick and comprising non-stoichiometric tungsten oxide.

Abstract: A target for sputtering comprises SiZrxOy wherein x is higher than 0.02 but not higher than 5, and y is higher than 0.03 but not higher than 2*(1+x), wherein the target has an XRD pattern with silicon 2-theta peak at 28.29°+/?0.3°, or a tetragonal phase ZrO2 2-theta peak at 30.05°+/?0.3°. The target has a low resistivity, below 1000 ohm·cm, preferably below 100 ohm·cm, more preferably below 10 ohm·cm, even lower than 1 ohm·cm.
