Glass fusion method
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 between the first glass member and a thermal conductor 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 the region to be fused therealong with a first laser beam while using the thermal conductor as a heatsink, so as to melt the glass layer disposed between the first glass member and the thermal conductor, and fix the glass layer to the first glass member, the thermal conductor is situated so that it contacts the glass layer during the irradiation process;
removing the thermal conductor from the glass layer; 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 second laser beam so as to fuse the first and second glass members together.

Abstract
After a glass layer 3 is disposed between a glass member 4 and a thermal conductor 7 along a region to be fused, a laser beam L1 is emitted while the thermal conductor 7 is used as a heat sink, so as to melt the glass layer 3, thereby burning and fixing the glass layer 3 onto the glass member 4. While the glass layer 3 drastically increases its laser absorptance at the time of burning, the thermal conductor 7 serves as the heatsink and draws heat from the glass layer 3, thereby inhibiting the glass layer 3 from falling into an excessive heat input state. Thereafter, another glass member is overlaid on the glass member 4 having the glass layer 3 burned thereonto, such that the glass layer 3 is interposed therebetween. Then, the region to be fused is irradiated therealong with a laser beam, so as to fuse the glass members together.
