Patent abstract
A thin film device and fabrication method providing optimum tear resistance. A thin film layer is formed with a first and second of rows of holes. The holes in each row are spaced-apart along an axis which extends along an edge of the layer. The holes in one row are in overlapping relationship with adjacent holes in the other row. The holes have a diameter which is sufficiently large so that an imaginary line extending perpendicular from any location along the edge will intersect at least one hole, thus preventing further propagation of any tears or cracks which start from the edge.
