A wafer transfer system includes a transfer chamber defining a volume. The transfer chamber includes a wafer support within the volume to support a wafer. A first input gas nozzle is disposed above the wafer support and inputs a first flow of gas into the transfer chamber at a first flow speed. A second input gas nozzle is disposed below the wafer support and inputs a second flow of gas into the transfer chamber at a second flow speed different than the first flow speed. A first output gas structure guides the gas from the transfer chamber due to the second flow speed being different than the first flow speed such that suspended particles within the transfer chamber are at least one of directed away from the wafer support or directed toward the first output gas structure to guide the suspended particles from the transfer chamber.

Wafer transfer system and method of use

A semiconductor process system includes a semiconductor process chamber having an interior volume. A pump extracts gases from the semiconductor process chamber via an outlet channel communicably coupled to the semiconductor process chamber. The system includes a plurality of fluid nozzles configured to prevent the backflow of particles from the outlet channel to interior volume by generating a fluid barrier within the outlet channel responsive to the pump ceasing to function.

Semiconductor process chamber contamination prevention system

A semiconductor processing system processes semiconductor wafers in a process chamber. The process chamber includes semiconductor process equipment for performing semiconductor processes within the chamber. The process chamber includes a heat pipe integrated with one or more components of the process chamber. The heat pipe effectively transfers heat from within the chamber to an exterior of the chamber.

Semiconductor process chamber with heat pipe

Systems, apparatuses, and methods are provided for predicting or determining irregular processing parameters during processing of a semiconductor wafer in a semiconductor processing apparatus, such as an etching apparatus. A semiconductor processing apparatus includes a load port that is configured to receive a semiconductor wafer. A process chamber is coupled to the load port, and a fan is configured to selectively vary a flow of fluid in the process chamber. One or more sensors are provided in the process chamber and are configured to sense one or more processing parameters in the process chamber. A controller is coupled to the one or more sensors and to the fan, and the controller is configured to control the fan to vary the flow of fluid in the process chamber based on the sensed one or more processing parameters.
