Abstract:
1. A method for processing a base comprising: forming over a surface of a first base a first electrode having a projection and formed of a conductive material which exhibits an adhesiveness at a temperature not lower than a first temperature; forming a first insulating film of a first insulating material which exhibits an adhesiveness at a temperature not lower than a second temperature, covering the surface of the first base in a height less than a height of the first electrode; covering over the first insulating film including the first electrode with a second insulating film of a second insulating material which exhibits an adhesiveness at a temperature not lower than a third temperature; processing a surface of the first electrode and a surface of the second insulating film, by cutting with a cutting tool, to be continuously flat while retaining the surface of the first electrode and the second insulating film at a temperature lower than a lowest one of the first temperature, the second temperature and the third temperature; opposing a second base with a second electrode corresponding to the first electrode formed thereon to the surface of the first base, where the first electrode is formed thereon; and connecting the first base and the second base to each other and electrically connecting the first electrode and the second electrode to each other by an insulating film of the first insulating film and the second insulating film at a temperature not lower than a highest one of the first temperature, the second temperature and the third temperature.
