Patent ID: 7011737

Claim:
A method of producing an electrical resistive device, the method comprising the steps of: (a) forming an array of titania nanotubes open at an outwardly-directed end by anodizing at least a portion of a first titanium layer; (b) prior to said anodizing, depositing said first titanium layer atop an integral support member, which comprises an electrically insulative substrate layer, by performing a deposition process selected from the group consisting of: sputtering, evaporation using thermal energy, E-beam evaporation, ion assisted deposition, ion plating, electrodeposition, screen printing, chemical vapor deposition, molecular beam epitaxy (MBE), and laser ablation; and (c) after said step of depositing said first titanium layer and prior to said anodizing, depositing a second titanium layer, leaving a portion of said first titanium layer uncovered for said forming said array of titania nanotubes.
