摘要: A plasma processing apparatus includes a processing chamber having a working volume. A single Radio-Frequency (RF) plasma generating antenna is positioned outside the working volume for inducing an electric field in the working volume. A dielectric trough extends into a wall of the chamber. The antenna is non-planar and transfers power through at least one wall and the base of the trough.

摘要: A substrate is treated by supplying an etchant and/or deposition gas into a chamber in which the substrate is situated. In order to avoid the problems associated with transportation of toxic gases, the gases required for such processes are delivered directly from a gas generation and delivery system positioned locally to the chamber.

摘要: A plasma processing apparatus includes a chamber having a support for a substrate, and at least one gas inlet into the chamber. The apparatus is configured to alternately introduce an etch gas and a deposition gas into the chamber through the at least on gas inlet, and to strike a plasma into the etch gas and the deposition gas alternately introduced into the chamber. The apparatus is further equipped with an attenuation device for reducing and/or homogenizing the ion flux from the plasma substantially without affecting the neutral radical number density.

摘要: A workpiece is processed in a chamber by striking a plasma in the chamber, treating the workpiece by cyclically adjusting the processing parameters between at least a first step having a first set of processing parameters and a second step having a second set of process parameters, wherein the plasma is stabilized during the transition between the first and second steps. These steps may comprise cyclic etch and deposition steps. One possibility for stabilizing the plasma is by matching the impedance of the plasma to the impedance of the power supply which provides energy to the plasma, by means of a matching unit which can be controlled in a variety of ways depending upon the step type or time during the step. Another possibility is to prevent or reduce substantially variation in the pressure in the chamber between the first and second steps.

摘要: A plurality of antennae generate a plasma in the chamber containing a workpiece, and the relative outputs of the antennae are varied as a detector detects a property or parameter of the resultant plasma or process. The relative outputs of the antennae are controlled in accordance with the property or parameter detected. The detector, which detects the property or parameter at or near the workpiece location, is a Langmuir probe which is shielded from the plasma by a semiconductor or insulating layer and is driven.

摘要: Plasma processing apparatus frequently incorporates an antenna fed from a power supply and in this invention a power supply feeds a conventional matching circuit (10), which in turn is connected to the primary (11) of a transformer (12). The antenna (15) is coupled across the secondary winding (13) of the transformer (12) and that winding is tapped to ground at (16). This creates a virtual earth (17) near the mid point of the antenna (15) significantly reducing the variation, along the length of the antenna, in the power supplied to the plasma.
