Electron Beam Lithography,eting the demand of fine and high-speed writing. The electron-beam technology utilized in such a system is immature from the viewpoint of semiconductor production. In addition, it essentially requires modern technologies, such as electrooptics, precision machinary and Controlling electronics, a precision moving table, computers and software.驾驶 发表于 2025-3-25 17:57:18
