  • Selective laser-assisted transfer of discrete components
    Patent number: 9862141
    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.
    Type: Grant
    Filed: December 14, 2015
    Date of Patent: January 9, 2018
    Assignee: NDSU RESEARCH FOUNDATION
    Inventors: Val R. Marinov, Orven Swenson, Mark Pavicic, Ross A. Miller, Zhigang Chen, Ferdous Sarwar, Matthew R. Semler
