Abstract:
1. A method for manufacturing a glass package, said method comprising the steps of: providing a first glass plate, where the first glass plate has a coefficient of thermal expansion, CTE, in a range of about 80-90×10 providing a second glass plate; providing a frit, where the frit has a CTE that is about 35×10 depositing the frit onto the first glass plate or the second glass plate; placing the first glass plate on the second glass plate where the frit is located between the first glass plate and the second glass plate; using a laser to direct a laser beam through the first glass plate or the second glass plate towards the frit and then moving the laser beam at a predetermined sealing speed along the frit to heat the frit such that the frit melts and forms a seal which connects the first glass plate to the second glass plate; and wherein the laser beam forms a footprint on the frit, and has a residence time on a given point of the frit within the footprint that is equal to or greater than 100 msec.
