The present invention relates to antifouling coatings capable of being switched by using heat or ultraviolet light. Prior to switching, the coating includes an onium cation component having antimicrobial and antibacterial properties. Upon switching, the coating is converted to a conjugated polymer state, and the cationic component is released with any adsorbed biofilm layer. Thus, the coatings herein have switchable and releasable properties. Methods of making and using such coatings are also described.

The present invention is a compound for forming a metal-containing film, being a reaction product between a compound having two or more diol structures per molecule and a Sn compound, and being a monomolecular compound containing two or more Sn atoms per molecule. This can provide: a metal compound having better dry etching resistance than conventional organic underlayer film materials and also having high filling and planarizing properties; a composition for forming a metal-containing film containing the compound; and a patterning process in which the composition is used as a resist underlayer film material.
