Abstract: A temperature-controlled showerhead assembly is configured to deliver a plurality of gases into a cyclic deposition chamber. The showerhead assembly comprises a showerhead body having a cavity formed therethrough and at a central region thereof, wherein the cavity is configured to diffuse or mix the gases prior to introducing the gases into the deposition chamber. The showerhead assembly additionally comprises a network of cooling channels configured to conduct heat away from the showerhead body. The showerhead assembly further comprises a network of heating elements configured to supply heat to the showerhead body, wherein the network of heating elements is disposed closer to the an upper surface of the showerhead body relative to the cooling channels.

Abstract: A method and apparatus for forming a semiconductor device are provided. The method includes thermally treating a substrate having one or more silicon nanosheets formed thereon. Thermally treating the substrate includes positioning the substrate in a processing volume of a first processing chamber, the substrate having one or more silicon nanosheets formed thereon. Thermally treating the substrate further includes heating the substrate to a first temperature of more than about 250 degrees Celsius, generating hydrogen radicals using a remote plasma source fluidly coupled with the processing volume, and maintaining the substrate at the first temperature while concurrently exposing the one or more silicon nanosheets to the generated hydrogen radicals. The generated hydrogen radicals remove residual germanium from the one or more silicon nanosheets.

Abstract: The disclosed technology relates generally to semiconductor manufacturing, and more particularly to precursor delivery in cyclic deposition. In one aspect, a thin film deposition system comprises a thin film deposition chamber configured to deposit a thin film by alternatingly exposing a substrate to a plurality of precursors. The thin film system additionally comprises a precursor source connected to the thin film deposition chamber by a precursor delivery line, wherein the precursor delivery line comprises a high conductance line portion between the precursor source and a final valve outside of the thin film deposition chamber. The high conductance line portion is elongated in a flow direction and has a conductance that is at least four times greater than either of immediately adjacent low conductance line portions connected at opposing ends of the high conductance line portion.

Abstract: The disclosed technology relates generally to semiconductor manufacturing, and more particularly to precursor delivery in cyclic deposition. In one aspect, a method of depositing a thin film comprises alternatingly exposing a substrate in a thin film deposition chamber to a plurality of precursors. Exposing the substrate comprises introducing one of the precursors into the thin film deposition chamber through two or more atomic layer deposition (ALD) valves each configured to supply the one of the precursors.
