  • Patent number: 9887107
    Abstract: Rinsing methodologies and components to accomplish rinsing of tool surfaces in tools that are used to process one or more microelectronic workpieces. The invention can be used to rinse structures that overlie a workpiece being treated in such a manner to function in part as a lid over the process chamber while also defining a tapering flow channel over the workpiece. Rather than spray rinsing liquid onto the surface in a manner that generates undue splashing, droplet, or mist generation, a swirling flow of rinse liquid is generated on a surface of at least one fluid passage upstream from the surface to be rinsed. The swirling flow then provides smooth, uniform wetting and sheeting action to accomplish rinsing with a significantly reduced risk of generating particle contamination.

  • Patent number: 9881784
    Abstract: Disclosed is a substrate processing method. The method includes: supplying a rinse liquid, IPA, a first fluorine-containing organic solvent, a second fluorine-containing organic solvent to a wafer within an outer chamber of a liquid processing unit; conveying the wafer to a supercritical processing unit container; and supplying a supercritical processing fluorine-containing organic solvent in a supercritical high-pressure fluid state to the wafer within the supercritical processing unit container. At least during the supply of the IPA, a low-humidity N2 gas is supplied into the outer chamber so that the inside of the outer chamber is formed as a low-humidity N2 gas atmosphere, and thus moisture absorption into the IPA is prevented.

  • Patent number: 9820612
    Abstract: A barbeque grill scraper and related methods of use that utilize a scraping end formed of a heat-responsive material to remove char and other debris from the grilling surface. The grill scraper includes a conformable scraping edge formed of the heat-responsive material. As the conformable scraping edge is drawn back and forth along the heated grilling surface, a combination of pressure applied by a user as well as the heat of the grill surface results in the formation of individual grooves along the conformable scraping edge, wherein each groove is formed to match an upper profile of the grilling surface. Over time, the grooves fully conform to the upper profile of the grilling surface such that an entire cooking surface can be scraped clean of char and debris.

  • Patent number: 9689076
    Abstract: In a process for cleaning contaminating silicon dioxide SiO2 off of turbine blades, silicon dioxide that is on the turbine blades is reduced selectively in a vacuum process that takes place in dry conditions and at elevated temperature inside a high vacuum furnace, by feeding gas having a reducing action, consisting of hydrogen gas or carbon monoxide, is introduced into the high vacuum furnace. The temperature inside the high vacuum furnace is at least about 1000 degrees Celsius, and the residence time of the turbine blades in the high vacuum furnace is determined with reference to the diminishment of the SiO concentration, as analyzed with a mass spectrometer. The electrically heatable high vacuum furnace is evacuable by means of a vacuum system that consists of a backing pump and a turbomolecular pump with an adjustable throttle valve and a water-cooled baffle.
