  • Integral blocks, chemical delivery systems and methods for delivering an ultrapure chemical
    Patent number: 7334708
    Abstract: Integral blocks, chemical delivery systems and methods for delivering an ultrapure chemical to a point of use or to another integral block are provided. More particularly, the integral blocks include a recharge container block, a pressurization gas block, a purge gas block, a waste recovery block, a vacuum block, a solvent supply block, a degas block, a control block, and a filtration block. Various integral blocks may be selected to form a chemical delivery system, which is particularly suited for a given application. A chemical delivery system will typically comprise a chemical container block, a chemical delivery block, and a point of use in line with the chemical container block and chemical delivery block, as well as one or more integral blocks.

  • Purification of silicon-containing materials
    Publication number: 20050054211
    Abstract: 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.
