Thomas Hantschel, David K Fork, Dirk De Bruyker, Chinnwen Shih, Jeng Ping Lu, Christopher L Chua, Raj B Apte, Brent S Krusor: Release height adjustment of stressy metal devices by annealing before and after release. Palo Alto Research Center Incorporated, Bever Hoffman & Harms, Patrick T Bever, December 13, 2005: US06973722 (10 worldwide citation)

Spring structures are subjected to pre-release and post-release annealing to tune their tip height to match a specified target. Post-release annealing increases tip height, and pre-release annealing decreases tip height. The amount of tuning is related to the annealing temperature and/or time. Annea ...
