The structure of a three-dimensional dc magnetron discharge is clarified by the use of the PIC/MC method. Magnets are placed in the form of a racetrack with the practical dimensions of a commercial sputtering apparatus. The cathode sheath has a three-dimensional structure; the sheath is thinnest in the midst of magnets.
