Abstract

Gas panel devices are fabricated by forming arrays of parallel conductors on glass plates, overcoating the conductors with a glass dielectric and a refractory coating, positioning the plates such that the conductor arrays are substantially orthogonal to each other, sealing the plates and filling the resultant enclosed area with an ionizable gas. As the size and resolution of these panels continues to expand, it becomes increasingly difficult to fabricate the plates without an open in some of the lines such that a repair technique for repairing this problem is required.

Laser Conductor Repair Device

Gas panel devices are fabricated by forming arrays of parallel conductors on glass plates, overcoating the conductors with a glass dielectric and a refractory coating, positioning the plates such that the conductor arrays are substantially orthogonal to each other, sealing the plates and filling the resultant enclosed area with an ionizable gas. As the size and resolution of these panels continues to expand, it becomes increasingly difficult to fabricate the plates without an open in some of the lines such that a repair technique for repairing this problem is required.

A technique to repair such lines utilizing a laser technique for transferring conductive material from a source slide onto a close target to repair line opens operates as follows: Referring to the drawing, a lens 11 focuses a laser beam onto a source material 13 positioned on the lower portion of glass slide 15. The metallic conductor 17 having an open 18 to be repaired is formed on glass plate
19. In known laser repair techniques, the source material and the target to be repaired are moved together such that there is no relative movement between the two. Using this known technique, only a small amount of material directly above the target can be transferred, and many passes are necessary to form the necessary build-up for repair. In the present device, relative movement is provided between the source and the laser by imparting motion to the glass slide 15 in the direc...
