摘要： A chamber formed from an electrically conductive material is connected to a ground potential. A hot electrode formed from an electrically conductive material is disposed within the chamber in a substantially horizontal orientation and is physically separated from the chamber. The hot electrode includes a top surface defined to support a part to be measured. A radiofrequency (RF) transmission rod is connected to extend from a bottom surface of the hot electrode through an opening in a bottom of the chamber and be physically separated from the chamber. The RF transmission rod is defined to transmit RF power from a conductor plate in an electrical components housing to the hot electrode. An upper electrode formed from an electrically conductive material is disposed within the chamber in a substantially horizontal orientation. The upper electrode is electrically connected to the chamber and is defined to be movable in a vertical direction.

摘要： A showerhead electrode assembly for a plasma processing apparatus is provided. The showerhead electrode assembly includes a first member attached to a second member. The first and second members have first and second gas passages in fluid communication. When a process gas is flowed through the gas passages, a total pressure drop is generated across the first and second gas passages. A fraction of the total pressure drop across the second gas passages is greater than a fraction of the total pressure drop across the first gas passages.Figure 3

摘要： UPPER ELECTRODE BACKING MEMBER WITH PARTICLE REDUCING FEATURES AbstractComponents of a plasma processing apparatus includes a backing member with gas passages attached to an upper electrode with gas passages. To compensate for the differences in coefficient of thermal expansion between the metallic backing member and upper electrode, the gas passages are positioned and sized such that they are misaligned at ambient temperature and substantially concentric at an elevated processing temperature. Non-uniform shear stresses can be generated in the elastomeric bonding material, due to the thermal expansion. Shear stresses can either be accommodated by applying an elastomeric bonding material of varying thickness or using a backing member comprising of multiple pieces. Figure 1,
