摘要:
A support for a substrate processing chamber comprises a chuck having a substrate receiving surface, and a base comprising an upper wall comprising a recessed trench having (i) an attachment face at a first depth, and (ii) a fluid channel at a second depth. A lower wall is seated in the recessed trench and attached to the attachment face of the upper wall, to close the fluid channel. A fluid inlet is provided to supply a heat transfer fluid to the fluid channel and a fluid outlet provided to discharge the heat transfer fluid from the fluid channel.

A method of etching a low-k dielectric on, or removing resist from, a substrate. In the method, the substrate is placed in a process zone. An ionized gas is generated in a gas ionization zone above the process zone, by introducing a process gas into a gas ionization zone, maintaining the process gas at a pressure of less than about 0.1 mTorr, and coupling RF energy to the process gas to form an ionized gas. The ionized gas is passed through an ion filter to form a filtered ionized gas. The substrate is exposed to the filtered ionized gas to etch the low-k dielectric layer on the substrate or to remove or clean remnant resist on the substrate.

Embodiments of the invention disclosed herein generally relate to a hydride vapor phase epitaxy (HVPE) deposition chamber that utilizes a plasma generation apparatus to form an activated precursor gas that is used to rapidly form a high quality compound nitride layer on a surface of a substrate. In one embodiment, the plasma generation apparatus is used to create a desirable group-III metal halide precursor gas that can enhance the deposition reaction kinetics, and thus reduce the processing time and improve the film quality of a formed group-III metal nitride layer. In addition, the chamber may be equipped with a separate nitrogen containing precursor activated species generator to enhance the activity of the delivered nitrogen precursor gases.
