Title: Innovations of Jie Fu in Laser Lift Off Technology
Introduction
Jie Fu is an accomplished inventor based in Marlborough, MA (US), known for his significant contributions to laser lift off technology. With a total of 3 patents to his name, he has made strides in improving the efficiency and effectiveness of laser systems used in material separation.
Latest Patents
One of Jie Fu's latest patents focuses on laser lift off systems and methods. These innovations aim to provide monolithic laser lift off with minimal cracking by reducing the size of one or more beam spots in various dimensions. This reduction helps decrease plume pressure while maintaining sufficient energy for effective separation. By utilizing irradiation zones of different shapes and patterns, these systems enhance the efficiency of laser energy use, reduce cracking during layer separation, and ultimately improve productivity. The methods described also include separating layers of material by irradiating non-contiguous irradiation zones with laser lift off zones (LOZs) that extend beyond the irradiation zones. Furthermore, the shaping of irradiation zones and controlling their overlap helps avoid uneven exposure of the workpiece. Consistent with at least one embodiment, these systems can be employed for the monolithic lift off of one or more epitaxial layers on a semiconductor wafer substrate.
