The elementary device includes a coaxial applicator of microwave power that includes a conductive central core, a conductive external shield surrounding the central core, a medium located between the central core and the shield to propagate microwave energy, and an insulating body. The elementary device further includes a system to couple to a microwave generator and is disposed at the shield. The shield has a proximal end plugged with the insulating body made of dielectric material that is transparent to the microwave energy. The insulating body has an external surface configured to contact and excite a gas located in the interior of a chamber. The insulating body extends exterior wise from the shield and its external surface is nonplanar and protrudes from the shield.

Patent number: 8518162Abstract: A method is described for treating gas exhaust from a polysilicon etch process, which uses a plasma abatement device to treat the gas. The device comprises a stainless steel gas chamber having a gas inlet for receiving the gas and a gas outlet. As the gas may contain a halocompound and water vapor, the chamber is heated to a temperature that inhibits adsorption of water on the surface within the chamber, thereby inhibiting corrosion of the gas chamber. The gas is then conveyed to the gas chamber for treatment, and the temperature of the chamber is maintained above said temperature during treatment of the gas.Type: GrantFiled: July 27, 2006Date of Patent: August 27, 2013Assignee: Edwards LimitedInventors: James Robert Smith, Andrew James Seeley, Derek Martin Baker, Marilena Radoiu

Patent number: 8480861Abstract: In a method of treating a gas exhausted from a process chamber, the exhaust gas is conveyed to a vacuum pump (20) and a nitrogen purge gas is added to the exhaust gas for pumping with the exhaust gas. Gas exhaust from the pump is conveyed to an abatement device (28) for abating the exhaust gas. The amount of purge gas added to the exhaust gas is adjusted in response to a variation of the composition of the exhaust gas, or the composition of the gas supplied to the process chamber, to optimise the abatement of the exhaust gas.Type: GrantFiled: September 28, 2006Date of Patent: July 9, 2013Assignee: Edwards LimitedInventors: James Robert Smith, Marilena Radoiu, Stephen John Coles
