<p><P>PROBLEM TO BE SOLVED: To solve the problem that it becomes difficult to stably form a low-fusion-point metal layer on electrodes as the electrodes decrease in interval. <P>SOLUTION: (a) A resin film is formed on a surface of a substrate having pads formed on the surface to cover the pads. (b) The resin film is etched back to expose upper surfaces of the pads. (c) The pads having the upper surfaces exposed and the resin film remaining in a region where no pad is formed are coated with metal paste. (d) The substrate is heated to aggregate metal contained in the metal paste on the upper surfaces of the pads. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
