METHOD FOR FORMING CONNECTION TERMINAL

摘要

PURPOSE: A method for forming a connection terminal including a solder unit and a solder unit supporter is provided to efficiently reduce an external impact by changing the propagation direction of a crack. CONSTITUTION: A substrate with a UBM(Under Bump Metallurgy)(116) is prepared. A solder unit(141) comprised of a lower side of a cylindrical shape and an upper side of a sphere shape is formed. The lower side is combined with the UBM. A solder unit supporter(130) is formed on the substrate and surrounds the lower side. The solder unit supporter is arranged on the UBM.
