The invention relates to a plate element for a wafer boat for the plasma treatment of disk-shaped wafers, in particular semiconductor wafers for semiconductor or photovoltaic applications. The plate element is electrically conductive and has at least one holding unit on each side, for holding a wafer in a wafer holding region. The plate element has at least one recess in at least one side of the plate element and/or at least one opening in the plate element, wherein the at least one recess and/or the at least one opening in the plate element lies at least partially radially outside of the wafer holding region and directly adjacent thereto. The invention further relates to a wafer boat that has a plurality of plate elements of the above type arranged parallel to each other, wherein plate elements arranged adjacent are electrically insulated from each other. The invention further relates to a wafer boat in combination with a plasma treatment device, which has a process chamber for accommodating the wafer boat, means for controlling a process gas atmosphere in the process chamber in an open-loop or closed-loop manner, and at least one voltage source, which can be connected to the electrically conductive plate elements of the wafer boat in a suitable manner in order to apply a voltage between directly adjacent wafers held in the wafer boat.

Methods, systems, and computer programs are presented for determining wear of a consumable part in a semiconductor processing apparatus. One chamber includes a reference part, a consumable part, a transfer arm for transferring the substrate into the chamber, a sensor on the transfer arm, and a controller. The reference part is not subject to wear during operation of the chamber, while the consumable part is subject to wear. The sensor is configured to measure a first distance from the sensor to a surface of the consumable part as the transfer arm travels near the consumable part, and the sensor is configured to measure a second distance from the sensor to a surface of the reference part as the transfer arm travels near the reference part. The controller determines the wear amount of the consumable part based on the first distance and the second distance.

A vacuum processing apparatus that includes an inner wall member disposed inside of an outer side wall member of a vacuum container, the inner wall member surrounding a side of a sample stand on which a sample to be processed is placed and facing to a plasma generated in a chamber inside of the inner wall member. The apparatus also includes an upper member arranged in the vacuum chamber above a flange portion of the inner wall member, contacting with an upper surface of the flange portion and transmitting a force pressing downwardly in a state where the inside of the vacuum container is reduced in pressure. The inner wall member is thermally connected with a temperature adjusting device which controls a temperature of the inner wall member through the upper surface of the flange portion and the upper member.

Disclosed are systems, methods, and devices for generating radicals in an air stream at the intake of an internal combustion engine, as well as increasing the thrust of such air streams into the engine. A plasma generator including plasma actuators, dielectric barrier discharge electrodes, or both is positioned in the intake stream. Plasma actuators are disposed on the interior surface of the plasma generator, exposed to the intake stream. Dielectric barrier discharge electrodes protrude into the intake air stream. Plasma, preferably DBD plasma, glow plasma, or filamentary plasma, is generated in the air intake stream, creating radicals in the stream, mixing the radicals in the stream, and reducing drag while increasing thrust of air in the intake stream. A concentric cylinder can be further disposed in the plasma generator, with further plasma actuators, dielectric barrier discharge electrodes, or both, on the interior and exterior surfaces of the cylinder.

摘要:
Various embodiments herein relate to methods, apparatus and systems for forming a recessed feature in a dielectric-containing stack on a semiconductor substrate. Separate etching and deposition operations are employed in a cyclic manner. Each etching operation partially etches the feature. Each deposition operation forms a protective coating (e.g., a metal-containing coating) on the sidewalls of the feature to prevent lateral etch of the dielectric material during the etching operations. The protective coating may be deposited using methods that result in formation of the protective coating along substantially the entire length of the sidewalls. The protective coating may be deposited using particular reaction mechanisms that result in substantially complete sidewall coating. Metal-containing coatings have been shown to provide particularly good resistance to lateral etch during the etching operation. In some cases, a bilayer approach may be used to deposit the protective coating on sidewalls of partially etched features.
