2. Description of the Related Art Conventionally, a method called face-down bonding has been used as a method for mounting a semiconductor chip such as an IC or LSI on a ceramic substrate or the like. In such a method, solder balls are formed on a semiconductor chip and a circuit board, and after aligning them, the solder is melted and joined (reflow soldering). This face-down bonding method has an advantage that it can be applied to a semiconductor chip having a high degree of integration and a large number of terminals by arranging solder balls in a matrix to increase the terminal density.
