3D printed plasma arrestor for an electrostatic chuck
Abstract:
A method for manufacturing an arrestor for an electrostatic chuck includes printing first layers of an arrestor for an electrostatic chuck using a 3-D printer and an electrically non-conductive material. The first layers of the arrestor at least partially define a first opening to a gas flow channel. The method includes printing intermediate layers of the arrestor using the 3-D printer and the electrically non-conductive material. The intermediate layers of the arrestor at least partially define the gas flow channel. The method includes printing second layers of the arrestor using the 3-D printer and the electrically non-conductive material. The second layers of the arrestor at least partially define a second opening of the gas flow channel. At least one of the first opening, the second opening and/or the gas flow channel of the arrestor is arranged to prevent a direct line of sight between the first opening and the second opening of the arrestor.
