Abstract

A method for mounting an electronic circuit-constituting member on a substrate. The method includes preparing a substrate having a surface comprising a liquid-attracting first region and a liquid-repelling second region that surrounds the first region. The method also includes bringing water into contact with the surface of the substrate so as to dispose said water only on the said first region. The method further includes subjecting said substrate to a member-containing liquid that includes an organic solvent where an electronic circuit-constituting member are dispersed in the organic solvent to move said electronic circuit-constituting member to said water disposed on the said first region. The surface of the member is chemically modified with a silane coupling agent including a group with a C—Cl bond. Also, the method includes removing the water and the organic solvent from the surface of the substrate to mount said electronic circuit-constituting member on said substrate.
