Embodiments generally relate to gas circuits for distributing gases for processing of substrates applicable for semiconductor manufacturing. In one or more embodiments, flow controllers of a gas circuit are used to stabilize, distribute, and switch gases for processing of substrates applicable for semiconductor manufacturing. In one or more embodiments, a gas circuit includes one or more first flow controllers operable to flow a first gas, one or more second flow controllers operable to flow a second gas, and one or more valve assemblies. The valve assembl(ies) include a first supply line connected to a respective first flow controller and a second supply line connected to a respective second flow controller. The gas circuit further includes a plurality of valves operable to open and close the respective flow of the first gas and the second gas received from the first flow controller(s) and the second flow controller(s).

Fast switching gas circuits and processing chambers, and related methods and apparatus, for gas stabilization

Methods for detection using optical emission spectroscopy in which an optical signal is delivered from the process chamber to an optical emission spectrometer (OES). The OES identifies emission peaks of photons, which corresponds to the optical intensity of radiation from the photons, to determine the concentrations of each of the precursor gases and reaction products. The OES sends input signals of the data results to a controller. The controller can adjust process variables within the process chamber in real time during deposition based on the comparison. In other embodiments, the controller can automatically trigger a process chamber clean based on a comparison of input signals of process chamber residues received before the deposition process and input signals of process chamber residues received after the deposition process.

Methods for detection using optical emission spectroscopy

A method and apparatus for processing semiconductor substrates is described herein. The apparatus includes one or more growth monitors disposed within an exhaust system of a deposition chamber. The growth monitors are quartz crystal film thickness monitors and are configured to measure the film thickness grown on the growth monitors while a substrate is being processed within the deposition chamber. The growth monitors are connected to a controller, which adjusts the heating apparatus and gas flow apparatus settings during the processing operations. Measurements from the growth monitors as well as other sensors within the deposition chamber are used to adjust processing chamber models of the deposition chamber as substrates are processed therein.

A process chamber includes a chamber body having a ceiling disposed above a floor with a chassis and an injector ring disposed therebetween. Upper and lower clamp rings secure the upper and floors, respectively, in place. An upper heating module is coupled to the upper clamp ring above the ceiling. A lower heating module is coupled to the lower clamp ring below the floor.

Epitaxial deposition chamber

An apparatus for controlling temperature profile of a substrate within an epitaxial chamber includes a bottom center pyrometer and a bottom outer pyrometer to respectively measure temperatures at a center location and an outer location of a first surface of a susceptor of an epitaxy chamber, a top center pyrometer and a top outer pyrometer to respectively measure temperatures at a center location and an outer location of a substrate disposed on a second surface of the susceptor opposite the first surface, a first controller to receive signals, from the bottom center pyrometer and the bottom outer pyrometer, and output a feedback signal to a first heating lamp module that heats the first surface based on the measured temperatures of the first surface, and a second controller to receive signals, from the top center pyrometer, the top outer pyrometer, the bottom center pyrometer, and the bottom outer pyrometer, and output a feedback signal to a second heating lamp module that heats the substrate based on the measured temperatures of a substrate and the measured temperatures of the first surface.

Temperature profile measurement and synchronized control on substrate and susceptor in an epitaxy chamber

A method for processing a substrate within a processing chamber comprises receiving a first radiation signal corresponding to a film on a target element disposed within the processing chamber, analyzing the first radiation signal, and controlling the processing of the substrate based on the analyzed first radiation signal. The processing chamber includes a substrate support configured to support the substrate within a processing volume and a controller coupled to a first sensing device configured to receive the first radiation signal.
