Method for fabricating vacuum display devices and structures fabricated

摘要

A method for forming a vacuum display device elongated spacers therein and devices formed by such method are disclosed. In the method, a number of elongated spacers are first mounted in a clamping fixture such that the bottom edges of the spacers extends perpendicularly away from the clamping fixture and are sufficiently exposed. The clamping fixture with the elongated spacers are then pushed onto a substrate that is coated with a layer of adhesive material. After the bottom edges of the spacers are adequately coated with a layer of adhesive material, the clamping fixture is removed from the layer of adhesive and then pushed onto a lower glass panel of the vacuum display device with the spacers contacting spacings provided between active regions on the top surface of the lower glass plate. The completed structure may optionally be subjected to an annealing process at a temperature between about 250 DEG C. and about 600 DEG C. to improve the bond strength and to relieve the bonding stress. After the spacers are adequately bonded to the lower glass panel, the clamping fixture is removed and a top glass plate is bonded to the top edges of the spacers and four sidewall panels positioned at the peripheral areas of the vacuum display device to form a vacuum-tight chamber.
