Abstract: An elastomeric mask is provided that allows deposition of a variety of materials through mask openings. The mask seals effectively against substrate surfaces, allowing simple deposition from fluid phase, gas phase, and the like or removal of material using gaseous or liquid etchants. The mask then can be simply peeled from the surface of the substrate leaving the patterned material behind. Multi-layered mask techniques are described in which openings in an upper mask allow selected openings of a lower mask to remain un-shielded, while other openings of the lower mask are shielded. A first deposition step, following by re-orientation of the upper mask to expose a different set of lower mask openings, allows selective deposition of different materials in different openings of the lower mask. Pixelated organic electroluminescent devices are provided via the described technique.

Abstract: A reinforcing underlayment including dry uniform particles evenly applied to a wet bonding material layer on a surface of a substrate. The substrate, including the layers, is then cured to harden the one or more of the layers. A final coating or topcoat is applied to the cured surface of the substrate. The dry particles are evenly distributed onto the bonding material layer creating a uniform surface for subsequent coatings. The dry particles increase the strength of the liquid coatings increasing solid particle density within the coating system and thereby imparting properties not available for the liquid coatings. The present invention enables a user to easily introduce very heavy, dense, strong particles into a liquid coating and allows the user to apply very dense, heavy particles into and onto a wet bonding material layer followed by a subsequent wet topcoat layer which is cured as one contiguous material with reinforcement and underlayment strengthening coming from the added, dry particles.

Abstract: An apparatus and method for improved control of low viscosity fluid flow during electrohydrodynamic spray deposition of the fluid to coat small targets, such as medical devices like stents. The apparatus includes a target holder which applies a first electrical potential to a target, a coating fluid transporter such as a wick, a siphon tube or a siphon tube with a wick therein along which the coating fluid flows from a reservoir to a dispensing end of the transporter, and an electrode which applied a second electrical potential to the coating fluid sufficient to cause the coating fluid to be attracted from the dispensing end of the transporter toward the target. This provides a target coating apparatus with highly self-regulating coating fluid flow characteristics despite the low viscosity of the coating fluid, while producing highly consistent and uniform target coatings.
