(PhysOrg.com) -- One of the more interesting methods of pattern transfer available for a number of applications right now is Laser Induced Forward Transfer (LIFT). However, when working with organic material, there are some drawbacks to LIFT, as well as other drawbacks to making use of a high threshold UV or IR laser to effect the transfer. “Besides thermal degradation,” Seung Hwan Ko tells PhysOrg.com, “high laser threshold laser can also induce mechanical cracks on transfer material and problems in edge sharpness.”
