Abstract

The present invention provides a substrate liquid processing apparatus and a substrate liquid processing method. It is possible to prevent the occurrence of the electrostatic breakdown caused by the discharge of electric charges in a substrate. According to the invention, in the substrate liquid processing apparatus (1), a substrate liquid processing method, and a computer readable storage medium (48) having a substrate liquid processing program stored therein for performing liquid treatment to the substrate (2), prior to processing a circuit-forming surface of the substrate (2) with a chemical liquid, the substrate liquid processing apparatus performs an anti-static process for an surface opposite to the circuit-forming surface of the substrate (2) by an anti-static liquid, thereby emitting the electric charges on the substrate (2).

Description

technical field [0001] The present invention relates to a substrate liquid processing device, a substrate liquid processing method, and a computer-readable recording medium recorded with a substrate liquid processing program for performing liquid processing on a substrate with a processing liquid. Background technique [0002] Conventionally, when manufacturing semiconductor components, flat panel displays, etc., substrates such as semiconductor wafers and liquid crystal substrates are cleaned and etched using processing liquids such as cleaning agents and etchant using substrate liquid processing equipment. [0003] In this substrate liquid processing device, due to various reasons such as charging of the processing liquid and friction of the movable part, the substrate processed by the substrate liquid processing device, components constituting the substrate liquid processing device, etc. may be charged due to static electricity. charge. [0004] In addition, when the sub...
