摘要
A method of improving the magnetic field uniformity of a magnetron sputtering equipment is disclosed. The method includes providing an equipment having a magnetic field generating device and a magnetic field receiving surface; utilizing the equipment multiple times to acquire the magnetic field intensity distribution on the magnetic field receiving surface; preparing a compensation plate corresponding to the magnetic field intensity distribution, such that the area of the compensation plate corresponding to the area of the magnetic field receiving surface with stronger magnetic field has a stronger ferromagnetic property and the area corresponding to the area of the magnetic field receiving surface with weaker magnetic field has a weaker ferromagnetic property; and installing the compensation plate between the magnetic field generating device and the magnetic field receiving surface for improving the magnetic field uniformity of the magnetic field receiving surface.
