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 3):
The substrate liquid processing method of  claim 1 , further comprising:\n setting an etching time and an etching amount for etching the substrate in the liquid processing unit by supplying, from the etching liquid supply unit to the liquid processing unit, the etching liquid having the lower etching rate for the silicon nitride film than the predetermined standard etching rate for the silicon nitride film, as a first processing time and a first etching amount, respectively; setting an etching time and an etching amount for etching the substrate in the liquid processing unit by supplying, from the etching liquid supply unit to the liquid processing unit, the etching liquid having a higher etching rate for the silicon nitride film than the predetermined standard etching rate for the silicon nitride film, as a second processing time and a second etching amount; and controlling such that a sum of the first processing time and the second processing time becomes the standard processing time, and a sum of the first etching amount and the second etching amount becomes the standard etching amount.
