Abstract
Disclosed is a surface treatment liquid which enables simple and efficient hydrophobilization of a substrate and prevention of collapse of a resin pattern or etched pattern. Also disclosed are a surface treatment method using the surface treatment liquid, a hydrophobilization method using the surface treatment liquid, and a hydrophobilized substrate. When a substrate is hydrophobilized, the substrate is coated with a surface treatment liquid containing a silylating agent and a hydrocarbon non-polar solvent. When a pattern is prevented from collapse, the surface of a resin pattern formed on a substrate or etched pattern formed on a substrate by etching is treated using a surface treatment liquid containing a silylating agent and a solvent.
