Abstract
It is an object of the invention to provide coated particles excellent in the reliability of connection. The invention provides coated particles each comprising a metal-surfaced particle as a core and resulting from a partial surface modification of that core particle with an organic compound via a functional group (A) capable of binding to a metal.
Claims31
A coated conductive particle,
- which comprises a conductive metal-surfaced particle obtained by formation of a conductive metal layer on the surface of a core particle made of an organic compound and results from a partial modification of the surface of the conductive metal-surfaced particle with an organic compound via a functional group (A) bound to the metal.
An anisotropic coated conductive particle,
- which comprises a conductive metal-surfaced particle obtained by formation of a conductive metal layer on the surface of a core particle made of an organic compound and resulting from a partial modification of the surface of the conductive metal-surfaced particle with an insulating organic compound via a functional group (A) bound to the metal.
A coated conductive particle,
- which comprises a conductive metal-surfaced particle as a core and results from a partial modification of the surface thereof with an organic compound via a functional group (A) bound to the metal,
- wherein the conductive metal is at least one selected from the group consisting of gold, platinum, silver, copper, iron, nickel, aluminum, chromium, and solder.
