发明名称 MOLD FOR FORMING CONDUCTIVE BUMP, METHOD OF FABRICATING THE MOLD, AND METHOD OF FORMING BUMP ON WAFER USING THE MOLD
摘要 A mold for forming a conductive bump, a method of fabricating the mold, and a method of forming a bump on a wafer using the mold are provided. The bump can be formed by employing various materials, the mold can be repeatedly used several times because the mold is not damaged, and due to a high precision, the pitch of the bumps is not limited. The mold for forming a conductive bump comprises a first substrate having a groove to form a bump; a second substrate for vacuum adsorption formed below the first substrate, and having a through-hole in communication with the groove; and a mask layer formed on the first substrate, and used to form the groove.
