  • Publication number: 20230061477
    Abstract: A reaction chamber may comprise a reaction chamber volume enclosed within the reaction chamber; a susceptor configured to support a substrate disposed in the reaction chamber volume; a reaction space above the susceptor, and a lower chamber space below the susceptor, within the reaction chamber volume; and/or a sealing system causing the reaction space and the lower chamber space to be at least partially fluidly separate. A sealing system may comprise a spacer plate surrounding and coupled to the susceptor; and/or a spring coupled to the spacer plate and the susceptor having a spring bias toward a compressed position or an extended position, such that the spring bias facilitates creation of at least a partial seal between the spacer plate and the susceptor, causing at least partial fluid separation between the reaction space and the lower chamber space as the susceptor moves up and down within the reaction chamber.

  • Publication number: 20210340671
    Abstract: The present disclosure is generally directed to a solid source precursor delivery system. More specifically, the present disclosure is directed to a solid source precursor vessel that can be utilized to vaporize a supply of solid precursor stored within the vessel. The disclosed source vessel utilizes a plurality of individual cavities or pockets within the interior of the vessel. Each individual pocket may be loaded with precursor. In an arrangement, the pockets may be loaded with pre-formed blocks of compressed precursor material that typically have a higher density than was previously achieved when packing solid precursor within a source vessel. The increased density of the solid precursor material increases a capacity of the source vessel resulting in longer intervals between replacement and/or refilling the source vessel.

  • Publication number: 20210310123
    Abstract: The present disclosure pertains to embodiments of a flush fixture for flushing a showerhead assembly. The flush fixture includes two distinct cavities, an inner cavity and an outer cavity surrounding the inner cavity and not fluidly connected to the inner cavity. When the flush fixture is mounted to a showerhead, inner apertures are in fluid connection with the inner cavity and one or more exhaust holes are in fluid connection with the outer cavity. Separately accessing the inner apertures and the one or more exhaust holes allows the showerhead to be properly flushed.

  • Publication number: 20210214846
    Abstract: The present disclosure pertains to embodiments of a showerhead assembly which can be used to deposit semiconductor layers using processes such as atomic layer deposition (ALD). The showerhead assembly has a showerhead which has an increased thickness which advantageously decreases reactor chamber size and decreases cycling time. Decreased cycling time can improve throughput and decrease costs.
