Applied technology for laser material processing, with a focus on what was shown at Lasys from 5 to 7 June in Stuttgart, Germany
Enabling laser lift-off (LLO) system microMIRA by 3D-Micromac
3D-Micromac’s brand-new microMIRA LLO system provides highly uniform, force-free lift-off of flexible layers on wafers and large surface areas (up to GEN6) and at high speeds. The system is built on a highly customizable platform that can incorporate different laser sources, wavelengths and beam paths to meet each customer’s unique requirements.
The laser system can be used for a variety of applications, such as device lift-off from glass and sapphire substrates in semiconductor manufacturing as well as OLED and microLED display manufacturing. Additional applications include laser annealing and crystallization for surface modification.
The new laser lift-off system provides the following benefits:
• Force-free and extremely selective laser processing
• No damage due to thermo-mechanical effects
• Low production costs
• Elimination of costly and polluting wet chemical processes
• Integration of adjacent manufacturing steps for greater fab productivity

Measuring industrial lasers
Ophir Helios is a laser power meter that has been specially developed for use in industrial applications. In just a few tens of a second, it detects laser powers of up to 12kW without requiring any cooling and delivers good/bad signals to the user. The compact measuring device can be directly integrated into laser systems or production cells in order to automate performance measurements for the entire optical laser system.
Helios is protected by a safety glass and a robust, motorized metal lid. This ensures that the sensor remains clean in any environment and is also protected against minor bumps and bangs. Helios offers Profinet and Ethernet/IP, RS232 and USB interfaces.
By regularly and frequently measuring the laser power, slight deviations from setpoints can be detected immediately. This makes it possible to take remedial measures right away in order to discover trends and ensure consistently high production quality.
Automation Platforms For Laser Material Processing
Cutting, welding, marking, drilling or metal deposition are used in a wide variety of processes in many different industrial sectors to optimize manufacturing processes and to ensure the high quality of workpieces. This for example, is how the electronics manufacturing, semiconductor industry, automotive industry, or medical device technology benefits from the advanced capabilities for laser material processing. Today the laser performance is normally not a limiting factor for the productivity.
Process, material, work cycle, ambient conditions, and criteria such as throughput, precision, geometry tolerances, size of the machining surface, and contours, all make different demands on the automation platforms. For example, as far as throughput and precision is concerned, it is possible to meet the different requirements when system components such as the mechanics, laser control, and laser beam steering complement each other and communicate via a high-performance network solution. PI (Physik Instrumente) accepted the challenges in laser processing and offers automation platforms that allow both high quality and high throughput. The spectrum shown at the LASYS (hall 4, stand 4E15) will range from single-axis to multi-axis solutions where the control of the laser and the positioning systems has to run simultaneously.
