Abstract: A system to purge dissolved gases selectively from liquids can include a first contactor having two first contactor inlets and two first contactor outlets. The first contactor can receive liquid from a liquid source at a first inlet of the first contactor and an inert gas source at a second inlet of the first contactor, the inert gas can purge a first portion of gas from the liquid source. The first portion of purged gas exits the first contactor at a first outlet of the first contactor. The second contactor can receive input from the second outlet of the first contactor and the inert gas, the inert gas purges a second portion of the gas from the liquid source. The second portion of purged gas can exit the second contactor at a first outlet of the second contactor.

Abstract: Devices, systems, and methods employed in wet cleaning semiconductor devices are provided. In particular, systems that can deliver deionized water with the desired concentration of CO2 and methods of generating deionized water with a desired concentration of CO2 for use in wet cleaning of semiconductor devices are provided.

Abstract: An apparatus and method provide measurement of a constituent of a fluid, such as ozone in ozonated water. The apparatus includes a vessel to contain the fluid, a light source configured to direct a first band of light and a second band of light along a substantially shared path though the fluid, and a photosensor that senses the first band of light and the second band of light. The constituent has a greater absorption associated with the first band of light than with the second band of light. The method includes modification of a measured attribute of the component in response to the sensed second band of light to improve the accuracy of the measured attribute.

Abstract: The invention relates to a method and system for cleaning semiconductor elements accommodated in a tank which uses ozonized, deionized (DI) ultrapure water. According to the invention, ozone is generated in an ozone generator (3) according to the principal of silent electric discharge while admitting highly pure oxygen. Said ozone is fed to a contactor (7) through which DI water flows. The ozone is then dissolved in the DI water. While optionally admitting additional chemicals, the ozonized DI water is conducted through the tank (12) holding the semiconductor elements in order to clean the same, and the used DI water is carried away (15). In order to stabilize the ozone concentration, CO2 is added to the ozone/oxygen mixture generated by the ozone generator (7).
