Commercial Acceleration of Diamond Semiconductor

Scientists announced that they have developed a way to use lasers to make diamond wafers, which is expected to power the next generation of semiconductors.

Major Breakthrough in Diamond Semiconductor Laser Cutting Technology

Diamond is used in the semiconductor industry, and has a wide range of irreplaceable application advantages and prospects under high frequency and high voltage conditions. It is considered to be the most promising material for the preparation of the next generation of high power, high frequency, high temperature and low power loss electronic devices. Known as the "ultimate semiconductor". Based on the industry's long-term research and development activities, now diamond semiconductor has begun to gradually move towards practical. However, diamond is a typical representative of hard, brittle and difficult to process materials. At present, the main ways to cut diamond are water knife cutting, electric spark cutting and laser cutting.

Cutting method of polycrystalline diamond compact

Polycrystalline diamond and cemented carbide sintered together to make polycrystalline diamond compact, cut into the desired shape, can be made into a variety of tools. However, due to its high hardness, high melting point, high resistivity and high wear resistance, it cannot be cut by traditional processing methods.
