  • Publication number: 20190122873
    Abstract: An ion source device (10) includes a first magnetron cathode (14a) and a second magnetron cathode (14b, 208a, 208b), each having a respective central longitudinal axis (Ma, Mb) and an ion source unit (16) that emits ions to pass through a space between the cathodes, a surface (18) of the ion source unit facing generally the cathodes, the central longitudinal axes being spaced apart from each other by a distance A, a shortest line (D) joining a surface of the cathodes is of a distance B, a centre of the ion source unit lying on a line (E) perpendicular to and bisecting the shortest line, the shortest distance between the surface of the ion source unit and the shortest line is C, with B>10 mm and C<4 A.
