Patent ID: 7755081

Claim:
A thin film transistor comprising: a gate electrode; a dielectric layer prepared from a siloxy/metal oxide hybrid composition, the hybrid composition comprising a siloxy component and a metal oxide component; the siloxy component being selected from the group consisting of siloxanes, silsesquioxanes, and combinations thereof; the metal oxide component comprising a metal and an oxygen component; the metal being selected from the group consisting of titanium, aluminum, zirconium, hafnium, tantalum, strontium, yttrium, lanthanum and combinations thereof; and the oxygen component being selected from the group consisting of oxygen, methoxy, ethoxy, propoxy, isopropoxy, butoxy, tert-butoxy, sec-butoxy, phenoxy and combinations thereof; the siloxy component being present in the siloxy/metal oxide hybrid composition in an amount of from about 5 to about 95 percent by weight, and the metal oxide component being present in an amount of about 5 to about 95 percent by weight excluding the amounts of solvents that may be present in the siloxy/metal oxide hybrid composition; a source electrode; a drain electrode; and a semiconductor layer; wherein said dielectric layer has a dielectric constant of greater than about 3.0 and has a surface roughness of less than about 1 nm.
