摘要: A faceplate for a substrate process chamber comprises a first and second surface. The second surface is shaped such that the second surface includes a peak and a distance between the first and second surface varies across the width of the faceplate. The second surface of the faceplate is exposed to a processing volume of the process chamber. Further, the faceplate may be part of a lid assembly for the process chamber. The lid assembly may include a blocker plate facing the first surface of the faceplate. A distance between the blocker plate and the first surface is constant.

摘要: In one example, a process chamber comprises a lid assembly, a first gas supply, second gas supply, a chamber body, and a substrate support. The lid assembly comprises a gas box, a gas conduit passing through the gas box, a blocker plate, and a showerhead. The gas box comprises a gas distribution plenum, and a distribution plate comprising a plurality of holes aligned with the gas distribution plenum. The blocker plate is coupled to the gas box forming a first plenum. The showerhead is coupled to the blocker plate forming a second plenum. The first gas supply is coupled to the gas distribution plenum, and the second gas supply system is coupled to the gas conduit. The chamber body is coupled to the showerhead, and the substrate support assembly is disposed within an interior volume of the chamber body, and is configured to support a substrate during processing.

摘要: Exemplary semiconductor processing systems may include a processing chamber including a lid stack having an output manifold. The systems may include a gas panel. The systems may include an input manifold. The input manifold may fluidly couple the gas panel with the output manifold of the processing chamber. A delivery line may extend from the input manifold to the output manifold. The systems may include a first transmission line extending from a first set of precursor sources of the gas panel to the delivery line. The systems may include a second transmission line extending from a second set of precursor sources of the gas panel to the delivery line. The second transmission line may be switchably coupled between the delivery line and an exhaust of the semiconductor processing system.

摘要: An apparatus and a method for depositing a film layer that may have minimum contribution to overlay error after a sequence of deposition and lithographic exposure processes are provided. In one example, a method includes positioning a substrate on a substrate support in a process chamber, and flowing a deposition gas mixture comprising a silicon containing gas and a reacting gas to the process chamber through a showerhead having a convex surface facing the substrate support or a concave surface facing the substrate support in accordance with a stress profile of the substrate. A plasma is formed in the presence of the deposition gas mixture in the process chamber by applying an RF power to multiple coupling points of the showerhead that are symmetrically arranged about a center point of the showerhead. A deposition process is then performed on the substrate.

摘要: Exemplary semiconductor processing chambers may include a showerhead. The chambers may also include a substrate support characterized by a first surface facing the showerhead. The first surface may be configured to support a semiconductor substrate. The substrate support may define a recessed pocket centrally located within the first surface. The recessed pocket may be defined by an outer radial wall characterized by a height from the first surface within the recessed pocket that is greater than or about 150% of a thickness of the semiconductor substrate.
