Seal arrival material formation equipped glass component and the production manner, and electronic device and that production manner

摘要

Seal arrival Characteristic and the reliability of the electronic device are raised by repeatability well raising bond strength of the glass substrate at the time of laser seal arrival. Glass substrate 3 has the seal field. It can provide the seal arrival material formation 5 which consists of the calcination formation of the seal wearing glass material which contains with seal arrival glass and low the expansion being full filler and the laser absorber in the seal field. Seal arrival glass includes 20 - 68% SnO, 0.5 - 5% SnO and 20 - 40% PO in mass proportion. As for seal arrival material formation 5 the carbon residue tonnage is made the range 20 - 1000ppm in mass proportion. This kind of glass substrate it laminates with the glass substrate 2 which, possesses the component formation field which has 3 and the electronic device irradiates laser light 6 to seal arrival material formation 5 and glass substrate between 2 and 3 the seal it sticks by melting.
