Patent number: 8889023Abstract: A plasma processing apparatus includes a flow splitter for dividing a common gas into two common gas streams of common gas branch lines. A central introduction portion connected to one of the common gas branch lines supplies a common gas to a central portion of a substrate to be processed. A peripheral introducing portion connected to the other one of the common gas branch lines supplies the common gas to a peripheral portion of the substrate. The peripheral introducing portion has peripheral inlets arranged about a circumferential region above the substrate. An additive gas line is connected to an additive gas source to add an additive gas to at least one of the common gas branch lines. In addition, an electron temperature of a plasma in a region where the peripheral inlets are disposed is lower than that in a region where the introduction portion is disposed.Type: GrantFiled: December 27, 2012Date of Patent: November 18, 2014Assignee: Tokyo Electron LimitedInventors: Naoki Matsumoto, Wataru Yoshikawa, Yasuhiro Seo, Kazuyuki Kato
