  • Patent number: 6456378
    Abstract: In one embodiment, a photomask is provided having a set of alignment pattern openings and circuitry openings formed therethrough. With the photomask, the substrate is first photoexposed through one of the set of alignment pattern openings and the circuitry openings and not the other. After the first exposing, the substrate is second exposed through the other of the openings on the photomask. In another embodiment, a latent image of an alignment pattern is formed and received by a masking layer over a substrate. The position of the latent image of the alignment pattern is inspected relative to an underlying layer of material over the substrate. Alignment is ascertained through inspection of the latent image relative to the underlying layer of material. In another embodiment, an undeveloped photoresist layer is formed over a substrate.
