Abstract

A method of selective delivery of material to locations on a substrate using a continuous stream deposition device to deposit the material at selected locations on the substrate. This is achieved by creating a mask with an opening, locating the mask over the substrate and depositing the material through the opening onto the substrate. When locating the mask, over the substrate, a portion of the substrate is exposed through the opening and when the continuous stream deposition device is moved relative to the substrate and the mask, the continuous stream deposition device follows a path relative to the mask which intersects the opening. While the continuous stream deposition device moves, it discharges a continuous stream comprising the material to be delivered, to deposit the material through the mask at a discrete location on the substrate, at the intersection of the opening and the path of the continuous stream deposition device. Alternatively the mask may be dispensed with and two materials deposited on two intersecting paths whereby at the intersections the two materials react.
