CONDUCTIVE PARTICLES AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A conductive particle and a manufacturing method thereof are provided to form a conductive coating film through low temperature heat treatment by forming a seed particle on the surface of a base particle. CONSTITUTION: A base particle(1) comprises metal. The base particle comprises Cu or Ni. The base particle is formed into a sphere shape in which average diameter is 0.01 to 1,000micrometers. A second metal layer is formed on the base particle. A seed particle(3) is formed on the surface of second metal layer. A first metal layer(5) is formed on the second metal layer. The first metal layer comprises Au or Ag. The first metal layer surrounds the seed particle and comprises a bump which is projected. The height of the bump is 5 to 100nm.
