Provided is a substrate processing apparatus that removes a film by supplying a processing liquid to the peripheral edge of a substrate. An ejection unit ejects the processing liquid to the peripheral edge of the substrate held and rotated by a substrate holding unit. An ejection position setting unit sets the ejection position of the processing liquid of the ejection unit to correspond to the removal width of the film included in a recipe, and a property information acquisition unit acquires property information of the film to be removed. A correction amount acquisition unit acquires the correction amount for correcting the ejection position of the processing liquid based on the property information of the film, and an ejection position correction unit corrects the ejection position of the processing liquid by the ejection unit based on the correction amount acquired by the correction amount acquisition unit.

A method is provided for forming a biphilic surface on a substrate comprising copper, such as a heat exchanger surface, wherein the method involves forming one or more hydrophilic areas on the surface by reacting those areas with at least one of hydrogen peroxide and ammonium hydroxide to form copper oxide and forming hydrophobic areas on the surface by reacting those areas with ammonium hydroxide solution to form copper hydroxide or by chemical etching with a combination of hydrochloric acid, hydrogen peroxide, and iron chloride. The functional surface can exhibit temporal biphilicity in response to one or more stimuli in high performance heat transfer applications.

The invention relates to compositions and methods that are useful in etching a metal surface. In particular, the invention relates to novel acid compositions and methods of using such compositions in etching a metal surface, preferably an aluminum surface prior to anodizing to dissolve impurities, imperfections, scale, and oxide. The compositions are effective in maintaining their etching capacity and in removing smut produced by the etching of a surface as well as in general cleaning.

A method for constructing a micro-nano porous organic acid pretreatment layer on the metal surface and its application are provided. A pretreatment reagent used is prepared by chemically grafting organic acid with hydroxylation-rich polymer. After immersed in the pretreatment reagent for a period of time, the metal substrates are then dried and cured, and the organic acid pretreatment layer with a micro-nano porous structure and excellent adhesion is successfully formed. The present invention provides the pretreatment reagent and pretreatment process of the metal surface coating protection technology. The solvent is only pure water and realizes no organic solvation. The pretreatment layer has excellent adhesion with the metal substrate, rough and porous structure, and can be closely interlocked with the subsequent coating layer, which greatly enhances the anticorrosion performance of the whole coating system.
