METHOD FOR PRODUCING HERMETIC PACKAGE
A technical object of the present invention is to devise a method by which bonding strength between an element base and a sealing material layer can be increased without thermal degradation of a member to be housed inside, to thereby improve long-term reliability of a hermetic package. A method of producing a hermetic package of the present invention includes the steps of: preparing a ceramic base and forming a sealing material layer on the ceramic base; preparing a glass substrate and arranging the ceramic base and the glass substrate so that the glass substrate is brought into contact with the sealing material layer on the ceramic base; and irradiating the sealing material layer with laser light from a glass substrate side to seal the ceramic base and the glass substrate with each other through intermediation of the sealing material layer, to thereby provide a hermetic packages.
METHOD OF ANNEALING CERAMIC GLASS BY LASER
A method for annealing thin-films of ceramics such as Al.sub.2O.sub.3 on glass by laser such that the underlying glass substrate is unaffected by the laser heating. This is accomplished by applying a thin MgO buffer layer to the glass, depositing an amorphous ceramic layer on the textured transparent buffer layer, and annealing the ceramic layer with a heated line source. The ceramic layer crystallizing forming a ceramic coated substrate. The buffer layer is also textured which serves to induce texture in the Al.sub.2O.sub.3 film deposited on the buffer layer. The induced texture on the Al.sub.2O.sub.3 provides advantageous properties. The ceramic glass can be used for a variety of applications such as covers to solar panels, CICs used in satellites, displays, automobile windows, and substrates for LEDs.
