    Abstract: An FI having an in-situ particle detector and a method for particle detection therein are provided. In one aspect, the FI includes a fan, a substrate support, a particle detector, and an exhaust outlet. The fan, substrate support, and particle detector are arranged such that, in operation, the fan directs air towards the exhaust outlet and over a substrate on the substrate support to create laminar flow. The particle detector, positioned downstream from the substrate support and upstream from the exhaust outlet, analyzes the air and detects particle concentration before the particles are exhausted. The collected particle detection data may be combined with data from other sensors in the FI and used to identify the source of particle contamination. The particle detector may also be incorporated into other system components, including but not limited to, a load-lock or buffer chamber to detect particle concentration therein.

    Abstract: Embodiments described herein relate to apparatus and coating methods to reduce chamber arcing, for example, in HDP-CVD, PECVD, PE-ALD and Etch chambers. The apparatus include a ring shaped gas distributor used for in-situ deposition of coating materials, and a process chamber including the same. The ring shaped gas distributor includes a ring shaped body having at least one gas entrance port disposed on a first side thereof and a plurality of gas distribution ports disposed on a first surface of the ring shaped body. The plurality of gas distribution ports are arranged in a plurality of evenly distributed rows. The plurality of gas distribution ports in a first row of the plurality of evenly distributed rows is adapted to direct gas at an exit angle different from an exit angle of the plurality of gas distribution ports in a second row of the plurality of evenly distributed rows.
