  • Publication number: 20230220588
    Abstract: A method of forming an epitaxial stack on a plurality of substrates is provided. In a preferred embodiment, the method comprises providing a semiconductor processing apparatus. This semiconductor processing apparatus comprises a process chamber and a carousel for stationing a wafer boat before or after processing in the process chamber. The method further comprises loading the wafer boat into the process chamber, the wafer boat comprising the plurality of substrates. The method further comprises processing the plurality of substrates in the process chamber, thereby forming, on the plurality of substrates, the epitaxial stack. This epitaxial stack has a pre-determined thickness. The processing comprises unloading the wafer boat, one or more times, from the process chamber to the carousel until the epitaxial stack reaches the pre-determined thickness.

  • Publication number: 20230223255
    Abstract: A method and a wafer processing furnace for forming an epitaxial stack on a plurality of substrates is provided. In a preferred embodiment, the method comprises providing the plurality of substrates to a process chamber. A plurality of deposition cycles is executed, thereby forming the epitaxial stack on the plurality of substrates. The epitaxial stack comprises a plurality of epitaxial pairs, wherein the epitaxial pairs each comprises a first epitaxial layer and a second epitaxial layer, the second epitaxial layer being different from the first epitaxial layer. Each deposition cycle comprises a first deposition pulse and a second deposition pulse. The first deposition pulse comprises a provision of a first reaction gas mixture to the process chamber, thereby forming the first epitaxial layer. The second deposition pulse comprises a provision of a second reaction gas mixture to the process chamber, thereby forming the second epitaxial layer.

  • Publication number: 20230005744
    Abstract: A method of forming a structure includes supporting a substrate within a reaction chamber of a semiconductor processing system, the substrate having a recess with a bottom surface and a sidewall surface extending upwards from the bottom surface of the recess. A film is deposited within the recess and onto the bottom surface and the sidewall surface of the recess, the film having a bottom segment overlaying the bottom surface of the recess and a sidewall segment deposited onto the sidewall surface of the recess. The sidewall segment of the film is removed while at least a portion bottom segment of the film is retained within the recess, the sidewall segment of the film removed from the sidewall surface more rapidly than removing the bottom segment of the film from the bottom surface of the recess. Semiconductor processing systems and structures formed using the method are also described.
