Liquid processing apparatus, liquid processing method, and storage medium having computer program recorded therein
Abstract:
Provided is a liquid processing apparatus in which a target substrate is horizontally held on a substrate holding unit and rotated around a vertical shaft, and the chemicals are supplied from a chemical supplying unit to the bottom surface of the target substrate that is rotating. In particular, the liquid processing apparatus performs a first step in which the chemicals are supplied to the target substrate while rotating the target substrate at a first rotation speed, a second step in which the supply of the chemicals is halted and the chemicals are thrown off by rotating the target substrate at a second rotation speed higher than the first rotation speed, and a third step in which the rinse liquid is supplied to the target substrate while rotating the target substrate at a third rotation speed equal to or lower than the first rotation speed.
