Abstract
A misalignment detection device comprising a substrate, at least one integrated circuit (IC), and at least one detection unit is disclosed. The substrate comprises a first positioning pad and a second positioning pad adjacent to the first positioning pad. The integrated circuit is disposed on the substrate and comprises a first positioning bump and a second positioning bump adjacent to the first positioning bump. The first and second positioning bumps substantially correspond to the first and second positioning pads, respectively. The at least one detection unit is electrically coupled to the substrate, wherein the detection unit outputs a fault signal in response to a positioning shift occurring between the first and second positioning pads and the first and second positioning bumps.
