Patent number: 10892142Abstract: A system for fabricating a semiconductor device may include a chamber, an electrostatic chuck used to load a substrate, a power source supplying an RF power to the electrostatic chuck, an impedance matcher between the power source and the electrostatic chuck, and a power transmission unit connecting the electrostatic chuck to the impedance matcher. The power transmission unit may include a power rod, which is connected to the electrostatic chuck and has a first outer diameter, and a coaxial cable. The coaxial cable may include an inner wire, an outer wire, and a dielectric material between the outer and inner wires. The inner wire connects the power rod to the impedance matcher and has a second outer diameter less than the first outer diameter. The outer wire is connected to the chamber and is provided to enclose the inner wire and has a first inner diameter less than the first outer diameter and greater than the second outer diameter.Type: GrantFiled: November 7, 2018Date of Patent: January 12, 2021Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sangjean Jeon, Jinyoung Park, Chanhoon Park, Hoyong Park, Jin Young Bang, JungHwan Um, Il Sup Choi, Je-Woo Han
