Patent ID: 7125584

Claim:
A liquid film forming method of dropping a liquid to be spread on a substrate to be processed from a dropping nozzle or dropping nozzles of a dropping unit onto the substrate, and then moving the dropping unit and the substrate relatively while keeping the liquid dropping on the substrate, so as to form a liquid film on the substrate, wherein the relative movement of the dropping unit and the substrate is composed of straight movement along a file direction in which the dropping unit passes from one end side of the substrate through an upper space over the substrate to the other end side of the substrate, and movement along a rank direction, and a distance between a dropping start position and the adjacent edge of the substrate is relatively larger than a distance between a dropping end position and the adjacent edge of the substrate along the rank direction, and the distance between a liquid film and the adjacent edge of the substrate along the file direction is set so as to gradually become smaller from the dropping start position to the dropping end position.
