METHOD OF MAKING A TENSIONED FOCUS MASK |
摘要 |
The present invention provides a method of making a tensioned focus mask, which includes a set of parallel strands and a set of parallel wires that are perpendicular to the strands and separated from the strands by insulator means. The method includes attaching the strands to a mask frame and then coating the strands with a first insulator. The first insulator is then cured, and a second insulator is applied to the first insulator. Next, wires are wound over and in contact with the second insulator, by rotating the mask frame and by drawing a continuous wire from a source through a tensioner, while guiding the continuous wire into desired positions overlying the strands. Finally, the second insulator is heated until the wires attach to the second insulator.
