A method of sealing a workpiece comprising forming an inorganic film over a surface of a first substrate, arranging a workpiece to be protected between the first substrate and a second substrate wherein the inorganic film is in contact with the second substrate; and sealing the workpiece between the first and second substrates as a function of the composition of impurities in the first or second substrates and as a function of the composition of the inorganic film by locally heating the inorganic film with a predetermined laser radiation wavelength. The inorganic film, the first substrate, or the second substrate can be transmissive at approximately 420 nm to approximately 750 nm.
