Title: Innovator Yuji Hadano: Pioneering Laser Processing Technologies
Introduction
Yuji Hadano, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of laser processing technologies. With a remarkable portfolio of 11 patents, Hadano's innovative work continues to shape advancements in the industry.
Latest Patents
One of Hadano's notable inventions is a novel laser processing method that includes several key steps. This method involves stacking a scattered-light blocking film on the upper surface of a wafer, ensuring precise laser beam application. The process entails holding the lower surface of the wafer using a chuck table, forming a layer of water on the wafer's upper side, and irradiating specific regions with a laser beam while moving the chuck table and laser beam unit simultaneously. After the laser processing is completed, the scattered-light blocking film is removed to finalize the process.
Additionally, Hadano has developed a laser processing machine that enhances the efficiency of laser applications. This machine's laser beam application unit comprises a laser oscillator, spot shaper, polygon mirror, and condenser. The laser oscillator emits a pulsed laser beam, while the spot shaper ensures the spot profile is elongated in the Y-axis and shorter in the X-axis. The polygon mirror then disperses the shaped spot in the X-axis direction, and the condenser focuses the pulsed laser beam onto the workpiece held on the chuck table.
