In order to make a batch of multi-point fine bumps (protruding electrodes) as the fundamental electrode structure of electronic devices, self-formation method was conducted. With a micro optical recording by a CCD camera, the observation of the wetting behavior of fine molten droplets on metal electrodes and morphological evaluation of bumps were conducted for the proper condition of the self-formation process.
