Patent ID: 8584613

Claim:
A head for dispensing a thin film over a substrate, comprising: a body assembly extending a length between a first and a second end that is at least a width of the substrate, the body including; (a) a main bore defined between the first and the second ends within the head, the main bore connected to an upper side of a reservoir through a plurality of feeds that are defined between the main bore and the reservoir; and (b) a plurality of outlets connected to a lower side of the reservoir and extending to an output slot that extends the length between the first and the second ends, the plurality of feeds having a larger cross-sectional area than the plurality of outlets and the plurality of feeds are fewer than the plurality of outlets, wherein the main bore is parallel to the length of the body and perpendicular to the plurality of feeds and wherein fluid is configured to flow through the main bore, through the plurality of feeds along the bore and fill the reservoir up to at least a threshold level before fluid is evenly output as a film out of the output slot onto the substrate and cease to flow when the fluid level within the reservoir falls below the threshold level.
