Abstract:
Disclosed is a substrate liquid processing apparatus that includes: a liquid processing unit that performs a liquid processing on a film formed on a surface of a substrate with an etching liquid; an etching liquid supply unit that supplies an etching liquid to the liquid processing unit; and a controller that controls the etching liquid supply unit. The controller is configured to perform a control such that an etching liquid in a state of having a relatively low etching rate for the film is supplied from the etching liquid supply unit to the liquid processing unit so that the substrate is etched in the liquid processing unit, and then, an etching liquid in a state of having a relatively high etching rate for the film is supplied from the etching liquid supply unit to the liquid processing unit so that the substrate is etched in the liquid processing unit.

Claim (Index 2):
The substrate liquid processing method of  claim 1 , further comprising changing an etching rate for the silicon nitride film by changing a temperature or a concentration of the etching liquid.
