A lithographic (litho) hotspot is a defect on a wafer that is created during manufacturing by a combination of systematic process variation and resolution enhancement technology (RET) limitations.

Pattern matching (PM) was first introduced as the semiconductor industry began to shift from simple one-dimensional rule checks to the two-dimensional checks required by sub-resolution lithography.

"Z-pattern advertising" constructs advertisements based on the theory that people will scan images from left to right and, to a lesser extent, top to bottom. Ads with a narrative flow may benefit most ...
