    Abstract: An ICP plasma etching apparatus for etching a substrate includes at least one chamber, a substrate support positioned within the chamber, a plasma production device for producing a plasma for use in etching the substrate, and a protective structure which surrounds the substrate support so that, in use, a peripheral portion of the substrate is protected from unwanted deposition of material. The protective structure is arranged to be electrically biased and is formed from a metallic material so that metallic material can be sputtered from the protective structure onto an interior surface of the chamber to adhere particulate material to the interior surface.

    Abstract: A method of degassing semiconductor substrates includes sequentially loading a plurality of semiconductor substrates into a degas apparatus, and degassing the semiconductor substrates in parallel, the degassing of each semiconductor substrate commencing at a different time related to the time at which the semiconductor substrate was loaded into the degas apparatus. The method further includes unloading a semiconductor substrate from the degas apparatus when the semiconductor substrate has been degassed, while semiconductor substrates which were loaded later in the sequence are still being degassed. The degassing of the semiconductor substrates is performed at pressure of less than 10−4 Torr, and the degas apparatus is pumped continuously during the degassing of the semiconductor substrates.

    Abstract: A method is for etching a semiconductor substrate to reveal one or more features buried in the substrate. The method includes performing a first etch step using a plasma in which a bias power is applied to the substrate to produce an electrical bias, performing a second etch step without a bias power or with a bias power which is lower than the bias power applied during the first etch step, and alternately repeating the first and second etch steps.

    Abstract: A capacitively coupled Plasma Enhanced Chemical Vapour Deposition (PE-CVD) apparatus has a chamber, a first electrode with a substrate support positioned in the chamber, a second electrode with a gas inlet structure positioned in the chamber, and an RF power source connected to the gas inlet structure for supplying RF power thereto. The gas inlet structure has an edge region, a central region which depends downwardly with respect to the edge region, and one or more precursor gas inlets for introducing a PE-CVD precursor gas mixture to the chamber. The edge region and the central region both constitute part of the second electrode. The precursor gas inlets are disposed in the edge region and the central region is spaced apart from the substrate support to define a plasma dark space channel.
