FUSION-BONDING PROCESS FOR GLASS
First Claim
1. A glass fusing method for manufacturing a glass fusing structure by fusing first and second glass members together, the method comprising the steps of:
- disposing a glass layer on the first glass member along a region to be fused, the glass layer being formed by removing an organic solvent and a binder from a paste layer containing a glass powder, a laser-absorbing material, the organic solvent and the binder;
irradiating a part of the glass layer with a first laser beam, so as to melt the part of the glass layer and form a laser-absorbing part in the glass layer;
irradiating the region to be fused therealong with a second laser beam while using the laser-absorbing part as an irradiation initiation position, so as to melt the glass layer and fix the glass layer to the first glass member; and
overlaying the second glass member on the first glass member having the glass layer fixed thereto such that the glass layer is interposed therebetween, and irradiating the region to be fused therealong with a third laser beam, so as to fuse the first and second glass members together.

Abstract
A part of a glass layer 103 disposed along a region to be fused R is irradiated with a laser beam L1, so as to form the glass layer 103 with a laser-absorbing part 108a having a high laser absorptance. Then, while using the laser-absorbing part 108a as an irradiation initiation position, the region to be fused R is irradiated therealong with a laser beam L2, so as to melt the glass layer 103 and fix the glass layer 103 onto a glass member 104. Since the irradiation initiation position for the laser beam L2 has already become the laser-absorbing part 108a, a stable region where the melting of the glass layer 103 is stable can be formed immediately from the start point for initiating the irradiation with the second laser beam or nearby. The glass member 104 is fused to a glass member 105 through the glass layer 103 having such a stable region formed throughout the region to be fused R, so as to yield a glass fusing structure 101.
