摘要： Apparatus and processes are presented to contact a dry, preferably high purity inert gas with a chemical composition in a pressure vessel, or a wetting composition, to form a wet inert gas, which is then used to pressurize the chemical composition out of the pressure vessel. No additional space is needed for an external humidifier. Since a very small amount of vapor is needed to form a wet inert gas, the composition of chemical composition will not be significantly affected.

摘要： Systems and methods of purifying a silicon-containing material include the step of directing the silicon-containing material in a liquid state through an adsorption unit including an adsorbent material to facilitate adsorption of at least one component from the silicon-containing material. Alternatively, the silicon-containing material is directed, in liquid state and/or gaseous state, through two or more purification units, including an adsorption unit, a vaporization unit, a filter unit and a condenser. The silicon-containing material can be a low-k silicon-containing material such as trimethylsilane, tetramethylsilane, dimethyldimethoxysilane, tetramethylcyclotetrasiloxane, octamethylcyclotetrasiloxane, dimethylphenyl silane, and dimethyldivinyl silane.

摘要： An apparatus and method for holding a solid precursor in a sublimator such that the solid precursor can be vaporized for saturating a carrier gas. The apparatus may include alternating disks or shelves that form inner and outer passages, as well as spaces between the disks for fluidicly coupling the passages to create a winding, tortuous fluid flow path through the sublimator for optimizing solid vapor saturation. The method may include directing a carrier gas into a sublimation chamber, around the first shelf in the outer passage, over the first shelf in the space, around the second shelf in the inner passage, and back out of the sublimation chamber.

摘要： Briefly, this invention uses one or more pressure vessels having installed therein on its inside a balloon of flexible and non-expandable wall to smoothly and continuously deliver a chemical to any end user without contamination and gas dissolution. Since the balloon installed inside the pressure vessel isolates a high pressure gas from the chemicals, gas dissolution in the chemical and the resulted gas bubble problems are effectively eliminated. Further, contaminants in the high pressure gas which fills the balloon will not be transferred into the chemical and the extremely toxic chemical will not be transferred into the gas to be exhausted as a serious environmental issue. Unlike the vacuum/pressure system, the contamination by the ambient air leaking into the system is avoided because the disclosed delivery system is always with the pressure higher or equal to the ambient pressure.
摘要翻译：简而言之，本发明使用一个或多个压力容器，其内部安装有柔性和不可膨胀壁的气球，以平稳且连续地将化学品输送到任何最终用户，而不会污染和气体溶解。由于安装在压力容器内的气囊将化学物质中的高压气体隔离，因此气体溶解在化学物质中并导致气泡问题得到有效的消除。此外，填充气球的高压气体中的污染物将不会转移到化学品中，并且极其有毒的化学物质将不会作为严重的环境问题转移到待排出的气体中。与真空/压力系统不同，避免了泄漏到系统中的环境空气的污染，因为所公开的输送系统总是具有高于或等于环境压力的压力。
