Patent ID: 8382966

Claim:
A sputtering system comprising: a first sputter unit comprising: a first deposition material plate; a second deposition material plate, wherein the first and second deposition material plates face each other; and a first magnetic field generator disposed behind each of the first deposition material plate and the second deposition material plate, configured to generate a magnetic field; a second sputter unit comprising: a third deposition material plate; disposed next to the first deposition material plate; a fourth deposition material plate, disposed next to the second deposition plate, wherein the third and fourth deposition material plates face each other; and a second magnetic field generator disposed behind each of the third deposition material plate and the fourth deposition material plate, configured to generate a magnetic field; a first gas supply pipe disposed between the first and third deposition material plates, configured to discharge gas to the second and fourth deposition material plates; a second gas supply pipe disposed between the second fourth deposition material plates, configured to discharge gas to the first and third deposition material plates; a first substrate support unit, configured to support a first deposition substrate, oriented toward outer edges of the first and second deposition material plates; and a second substrate support unit, configured to support a second deposition substrate, oriented toward outer edges of the third and fourth deposition material plates, wherein the outer edges of the first and second deposition material plates that are closest to the substrate, and are oriented toward the first substrate support unit, are closer to each other than the inner edges of the first and second deposition material plates, and the outer edges of the third and fourth deposition material plates that are closest to the substrate, and are oriented toward the second substrate support unit are closer to each other than the inner edges of the third and fourth deposition material plates.
