METHOD AND/OR SYSTEM FOR COATING A SUBSTRATE
A system and/or method for coating a substrate. The system may include a chuck for holding and rotating the substrate, a dispensing subsystem for dispensing a coating material onto the substrate, and a shield member. The shield member may be movable towards and away from the substrate during the coating procedure. The shield member may have an inverted funnel shape. The shield member may include a central chamber through which a solvent vapor flows and a peripheral chamber that is fluidly separated from the central chamber through which a gas flows. During a coating procedure, the shield member may be moved very close to the substrate and the solvent vapor and gas may flow onto the substrate to create a solvent rich ambient around the substrate and prevent aerosols of the coating material from redepositing onto the substrate after being flung off due to spinning of the substrate.
METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE
A method of manufacturing a semiconductor device includes forming a protective layer over a substrate. The hydrophilicity of the protective layer is reduced. A resist layer is formed over the protective layer, and the resist layer is patterned.

TREATMENT OF SPIN ON ORGANIC MATERIAL TO IMPROVE WET RESISTANCE
The present disclosure provides example embodiments relating to conductive features, such as metal contacts, vias, lines, etc., and methods for forming those conductive features. In an embodiment, portions of an adhesion layer, barrier layer and/or seed layer is protected by a layer of an organic mask material as portions of the adhesion layer, barrier layer and/or seed layer are removed. The layer of organic mask material is modified to improve its resistance to penetration by wet etchants used to remove exposed portions of the adhesion layer, barrier layer and/or seed layer. An example modification includes treating the layer of organic mask material with a surfactant that is absorbed into the layer of organic mask material.

Methods and apparatus for digital material deposition onto semiconductor wafers
A microelectronic device is formed by dispensing discrete amounts of a mixture of photoresist resin and solvents from droplet-on-demand sites onto a wafer to form a first photoresist sublayer, while the wafer is at a first temperature which allows the photoresist resin to attain less than 10 percent thickness non-uniformity. The wafer moves under the droplet-on-demand sites in a first direction to form the first photoresist sublayer. A portion of the solvents in the first photoresist sublayer is removed. A second photoresist sublayer is formed on the first photoresist sublayer using the droplet-on-demand sites while the wafer is at a second temperature to attain less than 10 percent thickness non-uniformity in the combined first and second photoresist sublayers. The wafer moves under the droplet-on-demand sites in a second direction for the second photoresist sublayer, opposite from the first direction.

SUBSTRATE TREATMENT METHOD AND SUBSTRATE TREATMENT SYSTEM
A substrate treatment method for treating a substrate, includes: applying a coating solution containing an organometallic complex, a solvent, and an additive to the substrate to form a solution film of the coating solution; heating the substrate on which the solution film of the coating solution has been formed, to form an organic constituent-containing metal oxide film being a metal oxide film containing an organic constituent contained in the additive; performing dry etching using the organic constituent-containing metal oxide film as a mask; removing the organic constituent in the organic constituent-containing metal oxide film after the dry etching; and removing, by wet etching, a film obtained by removing the organic constituent from the organic constituent-containing metal oxide film.
