Abstract: A method for automatically characterizing plasma during substrate processing is provided. The method includes collecting a set of process data, which includes at least data about current and voltage. The method also includes identifying a relevancy range for the set of process data, wherein the relevancy range includes a subset of the set of process data. The method further includes determining a set of seed values. The method yet also includes employing the relevancy range and the set of seed values to perform curve-fitting, wherein the curve-fitting enables the plasma to be automatically characterized.

Abstract: An apparatus is provided for semiconductor wafer plasma processing. The apparatus includes a chamber having a lower electrode and an upper electrode disposed therein. The lower electrode is defined to transmit a radiofrequency current through the chamber to generate a plasma within the chamber. The upper electrode is disposed above the lower electrode and is electrically isolated from the chamber. A voltage source is connected to the upper electrode. The voltage source is defined to control an electric potential of the upper electrode relative to the chamber. The electric potential of the upper electrode as controlled by the voltage source is capable of influencing an electric potential of the plasma to be generated between the lower and upper electrodes.

Abstract: A chamber includes a lower electrode and an upper electrode. The lower electrode is defined to transmit a radiofrequency current through the chamber and to support a semiconductor wafer in exposure to a plasma within the chamber. The upper electrode is disposed above and in a spaced apart relationship with the lower electrode. The upper electrode is electrically isolated from the chamber and is defined by a central section and one or more annular sections disposed concentrically outside the central section. Adjacent sections of the upper electrode are electrically separated from each other by a dielectric material. Multiple voltage sources are respectively connected to the upper electrode sections. Each voltage source is defined to control an electric potential of the upper electrode section to which it is connected, relative to the chamber. The electric potential of each upper electrode section influences an electric potential of the plasma within the chamber.

Abstract: Methods using a probe apparatus configured to measure a set of electrical characteristics in a plasma include providing a chamber wall including at least a set of plasma chamber surfaces configured to be exposed to a plasma, the plasma having a set of electrical characteristics. The method includes installing a collection disk structure configured to be exposed to the plasma, wherein the collection disk structure having at least a body disposed within the chamber wall and a collection disk structure surface that is either coplanar or recessed with at least one of the set of plasma chamber surfaces and providing a conductive path configured to transmit the set of electrical characteristics from the collection disk structure to a set of transducers. The method may include coupling a thermal grounding element with the conductive path for providing thermal grounding to at least the conductive path and may alternatively or additionally include disposing an insulation barrier configured to substantially electrically separate at least one of the collection disk and the conductive path.
