    摘要： An electrostatic chuck device in which the electrostatic chuck and support are made from high resistivity, high thermal conductivity and low RF energy loss dielectric materials is described. An advantage of this electrostatic chuck device is that the wafer surface electromagnetic field distribution is more uniform than conventional electrostatic chuck devices. As a result, the wafer etch rate, especially the wafer edge etch rate non-uniformity, is significantly improved compared with conventional electrostatic chuck devices.

    摘要： A tandem processing-zones chamber having plasma isolation and frequency isolation is provided. At least two RF frequencies are fed from the cathode for each processing zones, where one frequency is about ten times higher than the other, so as to provide decoupled reactive ion etch capability. The chamber body is ground all around and in-between the two processing zones. The use of frequency isolation enables feed of multiple RF frequencies from the cathode, without having crosstalk and beat. A plasma confinement ring is also used to prevent plasma crosstalk. A grounded common evacuation path is connected to a single vacuum pump.

    摘要： The invention is embodied in an inductively coupled plasma reactor including a vacuum chamber for holding a wafer in the interior thereof and capable of containing a plasma gas, and having an RF antenna and an RF power source for supplying RF power to the RF antenna and apparatus for electrically isolating the RF antenna from the RF power source so as to reduce capacitive coupling therebetween. Preferably, the apparatus for isolating the antenna is a transformer having a primary winding connected across the RF power source and a secondary winding connected across the RF antenna. Preferably, the reactor further includes a conductive Faraday shield having plural layers, the Faraday shield being disposed between the RF antenna and the ceiling of the vacuum chamber, the Faraday shield having eddy current-suppressing apertures in each layer thereof facing conductive portions of the shield in an adjacent layer thereof. The ceiling of the vacuum chamber acts as a gas distribution manifold. The inner layer of the ceiling is the shower head of the manifold.

    摘要： A bonded multi-layer RF window may include an external layer of dielectric material having desired thermal properties, an internal layer of dielectric material exposed to plasma inside a reaction chamber, and an intermediate layer of bonding material between the external layer and the internal layer. Heat produced by the chemical reaction inside the chamber and by the transmission of RF energy through the window may be conducted from the internal layer to the external layer, which may be cooled during a semiconductor wafer manufacturing process. A bonded multi-layer RF window may include cooling conduits for circulating coolant to facilitate cooling of the internal layer; additionally or alternatively, gas distribution conduits and gas injection apertures may be included for delivering one or more process gases into a reaction chamber. A system including a plasma reaction chamber may employ the inventive bonded multi-layer RF window.
