Abstract:
A magnetron sputtering device, for depositing a film on a surface of a substrate by sputtering using magnetron discharge, comprising:a vacuum chamber to be filled with a specified sputter gas; a cathode and an anode for generating electric discharge inside the vacuum chamber; a sputtering target arranged inside the vacuum chamber for facing the substrate, provided with particle ejection sections constructed so as to be sloped at specified angles with respect to the surface of the substrate and facing each other; a first magnet arranged at an entire rear surface side of the sputtering target; and a second magnet arranged around the sputtering target, the particle ejection sections taking the shape of a unitary inside portion of a funnel without a central through-hole, wherein shield plates having holes corresponding to the sputtering target are arranged between the sputtering target and the substrate.
