Patent ID: 8076005

Claim:
A titanium-based layer, comprising: titanium, the amount of titanium in the layer being represented by Ti x , where x is between about 1 and about 4; and oxygen, the amount of oxygen in the layer being represented by O y , where y is between about 1 and about 7, wherein: the titanium-based layer is densified, has a uniform thickness, is substantially free from columnar structures, and has a figure of merit, defined as the product of a dielectric constant of the titanium-based layer and a breakdown voltage of the titanium based layer, greater than 200 through a deposition process using a pulsed-DC power supply, an RF-bias to the substrate, and reactive ion sputtering on a substrate, wherein the pulsed-DC power supply is applied to a conductive ceramic target through a narrow-band rejection filter centered to remove power from the RF-bias such that the target voltage oscillates between positive and negative voltages.
