Abstract: A gas distribution port insert, and equipment for use therewith, capable of suppressing or at least reducing process gas interaction with and/or back diffusion into a gas distribution body including the gas distribution port insert in association with a semiconductor processing tool.

Abstract: An apparatus includes a stem body and interior flow paths. The stem body has proximal and distal ends. The proximal end includes inlets, each of which is distinct and configured to receive a corresponding gas(es). The distal end is opposite the proximal end along a longitudinal axis of the stem body and configured to interface with a gas distributor. The distal end includes outlets, at least one of which is distinct. The interior flow paths include first and second interior flow paths. Each of the interior flow paths extends between a corresponding inlet among the inlets and at least one corresponding outlet among the outlets such that the interior flow paths are distinct from one another. Each of the interior flow paths includes structure(s) configured to induce turbulent flow along the longitudinal axis in response to a flow of the corresponding gas(es) along that interior flow path.

Abstract: An apparatus includes a main body having a first surface including gas distribution ports (hereinafter, “ports”). The first surface is divided into zones. The ports include: first ports distributed across a first zone among the zones, each first port being fluidically connected to a first gas inlet(s) via a corresponding first gas distribution flow path; second ports distributed across a second zone among the zones, each second port being fluidica Hy connected to a second gas inlet(s) via a corresponding second gas distribution flow path; and third ports distributed across a third zone among the zones, each third port being fluidically connected to a third gas inlet(s) via a corresponding third gas distribution flow path. The first zone separates the second and third zones from one another. Within the main body, the first gas distribution flow paths are separated from each of the second and third gas distribution flow paths.

Abstract: Various embodiments include apparatuses, systems, and methods for using a remote-plasma cleaning system with a directional-flow device for concurrently cleaning multiple processing stations in a processing tool used in the semiconductor and allied fields. In one example, an apparatus used to perform a remote-plasma clean (RPC) in a multi-station process chamber is disclosed and includes an RPC directional-flow device that is to be coupled between an RPC reactor and the process chamber. The RPC directional-flow device includes a number of ramped gas-diversion areas to direct at least a radical species generated by the RPC reactor to a separate one of the processing stations. An incoming cleaning-gas diversion hub is to receive the radical species and distribute at least the species substantially-uniformly to each of the of the ramped gas-diversion areas. Other apparatuses, systems, and methods are disclosed.

Abstract: Porogen accumulation in a UV-cure chamber is reduced by removing outgassed porogen through a heated outlet while purge gas is flowed across a window through which a wafer is exposed to UV light. A purge ring having specific major and minor exhaust to inlet area ratios may be partially made of flame polished quartz to improve flow dynamics. The reduction in porogen accumulation allows more wafers to be processed between chamber cleans, thus improving throughput and cost.

Abstract: A vaporizer useful for depositing material on a semiconductor substrate in a chamber of a chemical vapor deposition apparatus includes a first inlet configured to receive an atomized precursor, a second inlet configured to receive carrier gas, a flow path in fluid communication with the first and second inlets and configured to effect turbulent flow of an atomized precursor and carrier gas stream supplied to the first and second inlets. A plurality of heating elements includes a first heater element configured to heat a first zone of the flow path and a second heater element configured to heat a second zone of the flow path. An outlet in fluid communication with the flow path is configured to deliver vapor produced from the atomized precursor.

Abstract: Porogen accumulation in a UV-cure chamber may be reduced by removing outgassed porogen by flowing a purge gas across a window through which a wafer is exposed to UV light. Porogens in the purge gas stream may, as they flow through the chamber and into an exhaust baffle, deposit on surfaces within the chamber, including on the exhaust baffle. The exhaust baffle may have particular features that cause such porogen deposition to be more uniformly distributed across the exhaust baffle, thus reducing the amount of time that may be required to fully clean the baffle of accumulated porogens during a cleaning process.
