3D-Micromac’s CEO presenting at mini- & micro-LED display conference
3D-Micromac AG of Chemnitz, Germany (which provides laser micromachining and roll-to-roll laser systems for semiconductor, photovoltaic, glass and display applications) says that, at the TechBlick ‘Mini- & Micro-LED Displays: Markets, Manufacturing Innovations, Applications, Promising Start-ups’ event (being held virtually) its CEO Uwe Wagner is presenting ‘Laser technologies for the production of micro-LEDs’ on 1 December (at 4:55pm Central European Time) highlighting laser-based system solutions for various manufacturing steps for micro-LEDs, including the use of integrated process control and monitoring to assure stable and reliable operation to ensure high throughput and low yield losses.
3D-Micromac says that, although micro-LEDs have tremendous potential for future displays, several technical challenges must be overcome in the fabrication process prior to widespread deployment in the marketplace. One key hurdle is developing a process to release the dies from the sapphire growth wafer. Another is developing a process to transfer these dies to the display substrate with micron-level precision and reliability.
3D-Micromac addresses these challenges with its laser processing solutions, including its microMIRA Laser Lift-Off (LLO) system for separating the finished micro-LEDs from the sapphire growth wafer, and its microCETI Laser-Induced Forward Transfer (LIFT) system for moving the devices from the donor substrate to the display substrate. To date, 3D-Micromac has sold more than 10 laser processing systems for micro-LED applications, including a recent order for multiple microMIRA systems from a leading optical solutions provider.
3D-Micromac is also a founding member of the MicroLED Association, which was established earlier this year to accelerate the adoption of micro-LED display technologies by bringing together companies, researchers and organizations active in the micro-LED industry and providing a forum for solving common technology issues, fostering cooperation and sharing relevant information, resources and tools. 3D-Micromac sees the MicroLED Association as an important body to help establish close networking and cooperation between customers and technology providers for further market development, and sees group efforts around topics like standardization as key to boosting market entry and paving the way for new display technologies.
