Abstract:
Electronic components are often assembled using robotic equipment, such as pick-and-place machines, that is not optimized for components such as ultra-thin semiconductor bare dice. Selective laser-assisted die transfer is described based on the unique blistering behavior of a multilayer dynamic release layer when irradiated by low energy focused laser pulse(s) in which the blister creates translation of the article being placed. Accurate placement results are provided with negligible lateral and angular displacement.
