Low distortion stencil mask |
| abstract |
A stencil mask (10) has a membrane (14) under tensile stress and at least one pattern opening (22) formed through the membrane (14). A plurality of stress relief openings (30) are formed in the membrane for reducing stress-induced distortion of the membrane and the mask pattern. The stress relief openings (30) are positioned to relieve concentrations of stress within the membrane (14) such as those resulting from non-regularities within the pattern. In one embodiment, a screening material (56), less rigid than the membrane (14), is contained within the stress relief openings (30). |
