In some liquid crystal manufacturing processes, the containers, parts, and so on inside devices that are used need to have chemical purity on par with the level in semiconductor manufacturing applications. Focus is placed on high purity and whether volatile substances are present. Quartz glass is just about the only material that can meet all these requirements, and as such we offer quartz processed goods and materials for liquid crystal manufacturing applications, lamp materials used in cleaning processes, and quartz glass for optics in exposure equipment.
