A method and apparatus for delivering precursor materials to a processing chamber is described. The apparatus includes a gas distribution assembly having multiple gas delivery zones. Each zone may include a plenum having an inlet for receiving a precursor gas and at least one source of non-thermal energy, such as an infrared light source. The at least one source of non-thermal energy is may be varied to control the intensity of wavelengths from the infrared light source.

A method implemented by one or more processors, including receiving first information relating a plurality of flow rates of a species to corresponding concentrations of the species within films generated using the flow rates; receiving a desired concentration profile of the species within a desired film; and generating a plurality of process steps that, when performed, would form the desired film with the desired concentration profile by controlling the flow rate of the species based, in part, on the first information and the desired concentration profile, wherein a first concentration of the species at a first point in the desired concentration profile differs from a second concentration of the species at a second point in the desired concentration profile. A computer-readable medium, system and apparatus are also disclosed.

Method for CVD process control for enhancing device performance

A method and system for controlling the introduction of a species according to a determined concentration profile of a film comprising the species introduced on a substrate. In one aspect, the method comprises controlling the flow rate of a species according to a determined concentration profile of a film introduced on a substrate, and introducing a film on a substrate, the film comprising the species at a first concentration at a first point in the film and a second concentration different than the first concentration at a second point in the film. Also, a bipolar transistor including a collector layer of a first conductivity type, a base layer of a second conductivity type forming a first junction with the collector layer, and an emitter layer of the first conductivity type forming a second junction with the base layer. An electrode configured to direct carriers through the emitter layer to the base layer and into the collector layer is also included. In one embodiment, at least one of the first junction and the second junction is between different semiconductor materials to form at least one heterojunction. The heterojunction has a concentration profile of a semiconductor material such that an electric field changes in an opposite way to that of a mobility change.
