Abstract: A structured film for forming a pattern on a substrate includes a polymeric support layer, an adhesive layer, an etch resist layer disposed between the polymeric support layer and the adhesive layer, a structured resin layer disposed between the polymeric support layer and the etch resist layer, and one or more unstructured layers disposed between the etch resist layer and the adhesive layer. The structured resin layer has a structured major surface including a plurality of engineered structures. The etch resist layer at least partially fills spaces between adjacent engineered structures to substantially planarize the structured major surface.

Abstract: Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.

Abstract: Approaches for formation of a circuit via which electrically connects a first thin film metallization layer a second thin film metallization layer are described. Via formation involves the use of an anodization barrier and/or supplemental pad disposed in a via connection region prior to anodization of the first metallization layer. The material used to form the barrier is substantially impermeable to the anodization solution during anodization, and disrupts the formation of oxide between the electrically conducting layer and the barrier. The supplemental pad is non-anodizable, and is covered by the barrier to substantially prevent current flow through the pad during anodization. Following anodization, the barrier is removed. If the supplemental pad is sufficiently conductive, it can be left on the first metallization layer after removal of the barrier.

Abstract: A plasma hydrogenated region in the dielectric layer of a semiconductor thin film transistor (TFT) structure improves the stability of the TFT. The TFT is a multilayer structure including an electrode, a dielectric layer disposed on the electrode, and a metal oxide semiconductor on the dielectric. Exposure of the dielectric layer to a hydrogen containing plasma prior to deposition of the semiconductor produces a plasma hydrogenated region at the semiconductor-dielectric interface. The plasma hydrogenated region incorporates hydrogen which decreases in concentration from semiconductor/dielectric interface into the bulk of one or both of the dielectric layer and the semiconductor layer.
