摘要： There are provided a liquid processing method, a liquid processing apparatus and a recording medium for liquid processing which can enhance the uniformity of the coating state of a processing liquid on a substrate. A coating unit U1 includes a rotary holder 20 for rotating a wafer W, a nozzle 32 for supplying a processing liquid R onto a surface Wa of the wafer W, and a controller 60 for controlling the position of the nozzle 32 with respect to the wafer W. A liquid processing method includes: starting the supply of the processing liquid R to the surface Wa of the wafer W at an eccentric position at a distance from the center CL1 of rotation of the wafer W, and moving the position on the wafer W to which the processing liquid R is supplied toward the center CL1 of rotation of the wafer W while rotating the wafer W at a first rotational speed ω1; and, after the processing liquid supply position has reached the center CL1 of rotation of the wafer W, rotating the wafer W at a second rotational speed ω2 which is higher than the first rotational speed ω1, thereby allowing the processing liquid R to spread toward the periphery of the wafer W.

摘要： There is provided a coated film removing apparatus for removing, with a removal liquid, a peripheral portion of a coated film formed by supplying a coating liquid to a surface of a circular substrate, including: a rotary holding part configured to hold the substrate and rotate together with the substrate; a removal liquid nozzle configured to discharge the removal liquid on a peripheral portion of the surface of the substrate held by the rotary holding part so that the removal liquid is oriented toward a downstream side in a rotational direction of the substrate; and a control part configured to output a control signal so as to rotate the substrate at a rotation speed of 2,300 rpm or more when discharging the removal liquid.

摘要： There is provided a coating method which can apply a coating solution uniformly onto a substrate surface while reducing the amount of the coating solution supplied. The coating method for applying a coating solution onto a wafer includes the steps of: supplying a solvent for the coating solution onto the wafer to form an annular liquid film of the solvent in a peripheral area of the wafer; supplying the coating solution to the center of the wafer while rotating the wafer at a first rotational speed (time t1-t2); and allowing the coating solution to spread on the wafer by rotating the wafer at a second rotational speed which is higher than the first rotational speed (time t4-t5). The supply of the solvent is continued until just before the coating solution comes into contact with the liquid film of the solvent (time t0-t3).
