In this video, IPG Photonics represents a laser heating concept utilizing a flexible heating zone approach. There are processes that require non-uniform energy input, often due to convective effects that are difficult to address with uniform heat distribution systems. Fortunately, fiber delivered near-infrared (NIR) lasers from IPG Photonics can be flexibly configured to deliver a wide range of energy distribution possibilities that best support specific process requirements.

For example, an epi process incorporates complex gas flows over a rapidly rotating heated wafer to achieve uniform deposition rates. This dynamic environment is best addressed by numerous individually managed heating zones on the wafer surface, as shown in the video above.
