It has excellent thermal conductivity, high electrical insulation properties, and a thermal expansion coefficient close to that of silicon (Si), making it a focus as a high thermal conductivity material.
Aluminum nitride is used in heaters, electrostatic chucks, susceptors, clamp rings, cover plates, and other components for semiconductor manufacturing equipment, taking advantage of its high thermal conductivity and high corrosion resistance. It is also used in parts for medical devices such as MRI machines. MARUWA has established a consistent system from research and development to material production and machining, based on the material technology cultivated over many years. Through unique hot pressing methods and various machining processes, it is possible to meet the cutting-edge technological demands in semiconductor manufacturing equipment and medical applications.
