Patent number: 9773645Abstract: A remote plasma generator includes a body, a driver, and a protection tube. The body includes a gas injection port, a plasma exhaust port, and a plasma generation pipe through which discharge gas or plasma flow. The driver is coupled to the body and generates a magnetic field and plasma in the body. The protection tube is at an inner side of the plasma generation pipe to protect the plasma generation pipe from plasma.Type: GrantFiled: January 29, 2016Date of Patent: September 26, 2017Assignees: SAMSUNG ELECTRONICS CO., LTD., DANDAN CO., LTD., NEW POWER PLASMA CO., LTD.Inventors: Ja-woo Lee, Chung-huan Jeon, Heok-jae Lee, Jang-hyoun Youm, Sang-jean Jeon, Kwang-young Jung, Sun-uk Kim, Kang-ho Lee, Jung-hyun Cho, Soon-im Wi, Yun-sik Yang, Moo-jin Kim, Jang-kyu Choi
