Roll-to-Roll Laser Processing of Flexible Devices

In the manufacturing of flexible thin-film devices precision, throughput, and machining quality on ever-smaller structures are playing an important role. The presentation will give a brief overview of different case studies where roll-to-roll laser processing achieves new dimensions in terms of precision, quality, and process efficiency. An example application is the ablation of thin-film layers for medical sensors. In this case, the on-the-fly laser ablation takes place by using an excimer laser and mask projection. The layout of the products is adaptable by various projection masks. The high-repetition rate of the excimer laser allows the production of up to 150 sensors per second. Innovative laser micro-processes paired with sophisticated machining concepts from 3D-Micromac fulfill exactly all requirements for such sensitive and advanced devices.
