Patent number: 8759798Abstract: According to the present invention, an ion implantation system capable of implanting ions into a large substrate and reducing a manufacturing cost, and an ion implantation method using the same may be provided. The ion implantation system includes a plurality of ion implantation assemblies arranged in a line, each ion implantation assembly to implant ions into a partial region of the substrate. This allows for a compact ion implantation system to implant ions into a very large substrate. The substrate moves through the ion implantation system in a first direction, turns around, and then moves back through the ion implantation system in a second and opposite direction, where ions are implanted into the substrate while the substrate is moving in both directions. The path in the first direction can be spaced-apart from the path in the second direction to allow for two substrates to be processed simultaneously.Type: GrantFiled: September 20, 2011Date of Patent: June 24, 2014Assignee: Samsung Display Co., Ltd.Inventors: Hyun-Gue Kim, Sang-Soo Kim
