  • Patent number: 10892142
    Abstract: 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.

  • Patent number: 10672629
    Abstract: A ring assembly and a chuck assembly therewith are provided. The ring assembly may include an edge ring that is provided to enclose a chuck body supporting a substrate. The edge ring may include a first top surface, a second top surface positioned outside the first top surface and above the first top surface, a first inner side surface connecting the first top surface to the second top surface, and at least one first flow hole extending outward from one of the first top surface and the first inner side surface, thereby penetrating the edge ring.
