Abstract:
Implementations described herein disclose epitaxial deposition chambers and components thereof. In one implementation, a chamber can include a substrate support positioned in a processing region, a radiant energy assembly comprising a plurality of radiant energy sources, a liner assembly having an upper liner and a lower liner, and a dome assembly positioned between the substrate support and the radiant energy assembly.

Abstract:
The embodiments described herein generally relate to a flow control in a process chamber. The process chamber can include combinations of a flow control exhaust and a broad inject. The flow control exhaust and the broad inject can provide for controlled flow of process gases, as the gases both enter and leave the chamber, as well as controlling the gases already present in the chamber. Therefore, the overall deposition profile can be maintained more uniform.

Abstract:
Embodiments described herein generally relate to apparatus for processing substrates. The apparatus generally include a process chamber having a substrate support therein. A plurality of lamps are positioned to provide radiant energy through an optically transparent window to a substrate positioned on the substrate support. The plurality of lamps are positioned in a lamp housing. A cooling channel is formed in the lamp housing. A surface of the lamp housing is spaced a distance from the optically transparent window to form a gap therebetween. The gap functions as a fluid channel and is adapted to contain a fluid therein to facilitate cooling of the optically transparent window. Turbulence inducing features, such as openings, formed in the surface of the lamp housing induce a turbulent flow of the cooling fluid, thus improving heat transfer between the optically transparent window and the lamp housing.
Abstract:
Embodiments described herein generally relate to a susceptor support for supporting a susceptor in a deposition process. The susceptor support includes a shaft, a plate with a first major surface coupled to the shaft, and a support element extending from a second major surface of the plate. The plate may be made of a material that is optically transparent to the radiation energy from a plurality of energy sources disposed below the plate. The plate may have a thickness that is small enough to minimize radiation transmission loss and large enough to be thermally and mechanically stable to support the susceptor during processing. The thickness of the plate may range from about 2 mm to about 20 mm.
Abstract:
A method and apparatus for processing a semiconductor substrate is described. The apparatus is a process chamber having an optically transparent upper dome and lower dome. Vacuum is maintained in the process chamber during processing. The upper dome is thermally controlled by flowing a thermal control fluid along the upper dome outside the processing region. Thermal lamps are positioned proximate the lower dome, and thermal sensors are disposed among the lamps. The lamps are powered in zones, and a controller adjusts power to the lamp zones based on data received from the thermal sensors.
