A method for sealing a workpiece, the method comprising forming an inorganic film on the surface of a first base material, placing the workpiece to be protected between the first base material and a second base material, wherein the inorganic film and the second contacting the substrates; and sealing the workpiece to the first and second substrates by the effect of the composition of impurities in the first or second substrate and the composition of the inorganic film which locally heats the inorganic film at a predetermined wavelength of laser radiation between. The inorganic film, first substrate or second substrate may be transmissive at about 420-750 nm. |
