Abstract

The objects of the present invention are to provide a treatment liquid able to inhibit pattern collapse in a microstructure such as a semiconductor device or a micromachine, as well as a method of manufacturing a microstructure using the same. Means to solve the problems is to treat a microstructure with a treatment liquid for inhibiting pattern collapse in a metal microstructure comprising an alkylphosphonic acid or salt thereof in which said alkyl moiety contains 6 to 18 carbon atoms, water, and a water soluble solvent.
