摘要： In a process and an apparatus for preparing (cyclo)aliphatic polyisocyanates containing biuret groups from (cyclo)aliphatic diisocyanates and steam or a substance capable of splitting off water as reactants which are mixed with one another in a stirred reactor, the reactants are passes in countercurrent through a cascade-type stirred reactor comprising at least two stages. The dispersion of the gaseous reactant in the liquid reactant is reinforced by baffles installed in the stirred reactor. As baffles, use is made of discs provided with central openings and arranged at a distance from one another and/or strip baffles running in the longitudinal direction of the stirred reactor.

摘要： The present invention provides systems, methods and apparatus for depositing titanium films at rates up to 200 .ANG./minute on semiconductor substrates from a titanium tetrachloride source. In accordance with an embodiment of the invention, a ceramic heater assembly with an integrated RF plane for bottom powered RF capability allows PECVD deposition at a temperature of at least 400.degree. C. for more efficient plasma treatment. A thermal choke isolates the heater from its support shaft, reducing the thermal gradient across the heater to reduce the risk of breakage and improving temperature uniformity of the heater. A deposition system incorporates a flow restrictor ring and other features that allow a 15 liters/minute flow rate through the chamber with minimal backside deposition and minimized deposition on the bottom of the chamber, thereby reducing the frequency of chamber cleanings, and reducing clean time and seasoning. Deposition and clean processes are also further embodiments of the present invention.

摘要： A substrate processing chamber, particularly a chemical vapor deposition (CVD) chamber used both for thermal deposition of a conductive material and a subsequently performed plasma process. The invention reduces thermal deposition of the conductive material in a pumping channel exhausting the chamber. The pumping channel is lined with various elements, some of which are electrically floating and which are designed so that conductive material deposited on these elements do not deleteriously affect a plasma generated for processing the wafer.
