Using a femtosecond laser, embossing was performed on silicon carbide.
You can confirm that hemispherical convex shapes with a diameter of 100μm, a pitch of 150μm, and a height of 30μm are arranged in a staggered pattern at 60 degrees.

basic information
Silicon carbide, which has a hardness second only to diamond and excels in heat resistance, thermal shock resistance, and toughness at high temperatures, is expected to play a significant role in carbon neutrality, particularly in applications such as power inverters for electric vehicles and converters for solar and wind power generation, leading to increasing demand. On the other hand, its properties make machining difficult; however, ultra-short pulse laser processing can achieve fine machining essential for miniaturization of products, regardless of the hardness of the material.

Company information
At Lips Works Co., Ltd., we provide contract micro-fine processing using ultra-short pulse lasers, as well as the design and manufacturing of laser systems. In our contract processing business, we have been quick to engage in the development of industrial ultra-short pulse lasers and have been involved in contract micro-fine processing using these lasers. We specialize in applying fine periodic structures (microtextures) to work surfaces aimed at controlling tribological properties, optical properties, and release/adhesion characteristics. We can accommodate requests from small-scale prototypes to mass production according to our customers' needs. In our system engineering business, we leverage the laser processing technology cultivated in our job shop to provide a comprehensive service from selecting laser oscillators suitable for applications, designing optical systems, devising fixtures and auxiliary equipment, to system integration. We assist in improving the precision and efficiency of the processing required by our customers. As experts in laser technology providing cutting-edge laser processing techniques, we strive to be a valuable resource for our customers, so please feel free to contact us.
