Abstract: A reflector includes a reflector body having a slotted surface, a planar surface, and an ellipsoidal surface. The planar surface is opposite the slotted surface and is separated from the slotted surface by a thickness of the reflector body. The ellipsoidal surface is offset from the planar surface, is opposite the slotted surface and separated from the slotted surface by the thickness of the reflector body and spans the slotted surface of the reflector body. The ellipsoidal surface defines an elliptical profile that is orthogonal relative to the planar surface to concentrate heat flux at a distal focus of the elliptical profile using electromagnetic radiation reflected by the ellipsoidal surface of the reflector body. Semiconductor processing systems and material layer deposition methods are also described.

Abstract: A method of forming a structure is provided. The method includes supporting a substrate within a reaction chamber of a semiconductor processing system, flowing a silicon precursor and a germanium precursor into the reaction chamber, and forming a silicon-germanium layer overlaying the substrate with the silicon containing precursor and the germanium precursor. Concentration of the germanium precursor within the reaction chamber is increased during the forming of the silicon-germanium layer overlaying the substrate.

Abstract: A method of forming a silicon germanium layer on a surface of a substrate and a system for forming a silicon germanium layer are disclosed. Examples of the disclosure provide a method that includes providing a plurality of growth precursors to control and/or promote parasitic gas-phase and surface reactions, such that greater control of the film (e.g., thickness and/or composition) uniformity can be realized.

Abstract: A material layer deposition method includes supporting one and only one substrate in a chamber arrangement, exposing the substrate to a first material layer precursor and a second material layer precursor, and forming a first material layer overlaying the substrate using the first material layer precursor and the second material layer precursor. The first material layer is exposed to the first material layer to the first material layer precursor and a second material layer formed onto the first material layer using the first material layer precursor. The second material layer precursor includes a germanium-containing material layer precursor and the first material layer precursor includes at least one of trisilane (Si3H8) and tetrasilane (Si4H10). Material layer stacks, semiconductor processing systems, and computer program products are also described.

Abstract: A semiconductor processing system includes a chamber arrangement, an exhaust arrangement connected to the chamber arrangement, an accretion sensor supported within the exhaust arrangement, and a processor. The processor is disposed in communication with the accretion sensor and is responsive to instructions recorded on a non-transitory machine-readable medium to receive an accretion signal from the accretion sensor, the accretion signal indicative of an accretion amount disposed within the exhaust arrangement, receive a predetermined accretion amount value, and compare the accretion amount to the predetermined accretion amount value. The instructions further cause the processor to execute an accretion countermeasure when the received accretion amount is greater than the predetermined accretion amount value. Methods of controlling accretion within exhaust arrangements for semiconductor processing systems and foreline assemblies for semiconductor processing systems are also described.
