Abstract
Some embodiments include a semiconductor package. The semiconductor package has a semiconductor die with a primary region which includes integrated circuitry, and with an edge region which includes a portion of an alignment mark location. The portion of the alignment mark location includes a segment of an alignment mark. The alignment mark includes a pattern of lines and spaces, with the lines extending along a first direction. The portion of the alignment mark location also includes a texture having a pattern other than lines extending along either the first direction or along a second direction substantially orthogonal to the first direction. Some embodiments include methods for alignment marking semiconductor wafers.
