Filed: 1979-05-04
Abstract: PURPOSE:To obtain magnetic film on plated substrate, by using ferromagnetic body for target of a magnetron type spatter device and providing the target with magentic field higher in value than magnetic saturation value. CONSTITUTION:Ar is introduced into a device and maintained at a presoribed pressure, and by using a magnet 2 of higher magnetic force, magnetic field higher in value than magnetic saturation value is given to target 1 consisting of Fe, Ni and Co constituting spatter material. As to strength of magnetic field generating on the surface of the target, as it has to be larger toward lower vacuum, adjustment is to be made by thickness and shape of the target. By impressing voltage between the target and anode 10 in this condition to allow glow discharge to take place, the spatter material is expelled from the target by the anode and magnetic film 13 is formed on plated substrate 12. It is possible in this manner to prepare ferromagnetic low- temperature high-speed spatter, and this method is particularly effective in the case of forming magnetic film on the surface of plastic which is susceptible to thermal damage.
