    Abstract: A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.

    Abstract: The present invention provides a wafer container and a gas diffusion device applied in the wafer container. The wafer container includes a shell, and all components included and applied on the shell are made of thermal resistance materials. The gas diffusion device and the wafer container, when assembled together, utilize a coupling structure and a collar as a protection mechanism for the gas diffusion device. The gas diffusion device has a buffering chamber that provides a buffering tolerance and a communicating space for the gas before the gas enters an interior space of the wafer container.

    Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle. This may reduce pattern defects transferred to substrates that are patterned using the reticle, may increase semiconductor device manufacturing quality and yield, and may reduce scrap and rework of semiconductor devices and/or wafers.
