Abstract:
1. A method for manufacturing a semiconductor device, comprising: forming an electrode pad on a surface layer of an insulating layer; disposing a conductive particle, of which at least a portion of a surface is coated with a thermoplastic resin, over said electrode pad; and fixing said conductive particle over said electrode pad using said resin, by heating said resin to soften said resin, and then cooling and solidifying said resin after said conductive particle and said electrode pad are electrically connected to each other, to form said conductive particle as an external connection terminal, wherein said step of disposing said conductive particle over said electrode pad includes applying an electric charge to said conductive particle, and disposing said charged conductive particle over said insulating layer while a voltage having a polarity reverse to that of said conductive particle is applied to said electrode pad, and disposing said conductive particle over said electrode pad by causing an attraction to electrically act between said conductive particle and said electrode pad, and wherein said electrode pad is connected to a substrate of said semiconductor device through a protective device for preventing electrostatic breakdown, and in said step of disposing said conductive particle over said electrode pad, said semiconductor device is placed on a stage of which at least a surface is conductive, and said voltage having a reverse polarity is applied to said electrode pad through said substrate of said semiconductor device and said protective device for preventing electrostatic breakdown by applying said voltage having said reverse polarity to said surface of said stage.
