6482968, Nov 19, 2002

Filed:

Feb 7, 2002

Appl. No.:

09/980044

Inventors:

Nam H. Tran - Pasadena TX
Joseph N. Christopher - League City TX
Timothy J. Michalec - Needville TX

Assignee:

Akzo Nobel NV - Arnhem

International Classification:

C07F 506

US Classification:

556187

Abstract:

Organometallic compounds, as exemplified by trimethylaluminum, can be purified by recrystallization from a solvent by cooling. The organometallic compound is first dissolved in a solvent forming a solution and the purified organometallic compound is then recrystallized, under cooling conditions, from the solvent.

International Classification:

C23C 16/12

US Classification:

427250, 42725523, 427543, 427422, 427427

Abstract:

A process for depositing a substantially pure, conformal metal layer on one or more substrates through the decomposition of a metal-containing precursor. During this deposition process, the substrate(s) is maintained at a temperature greater than the decomposition temperature of the precursor while the surrounding atmosphere is maintained at a temperature lower than the decomposition temperature of the precursor. The precursor is dispersed within a transport medium, e. g. , a vapor phase. The concentration of the metal-containing precursor(s) in the vapor phase, which also contains liquid therein, can be at a level to provide conditions at or near saturation for the metal precursor(s). In ensuring the aforementioned temperature control between the transport media and substrate, and in maintaining saturation conditions for the transport media, the quality of the deposited metal thin film is markedly improved and the production of by-product metal dust is greatly reduced or substantially eliminated.

Abstract:

Selectively rebooting components of a computer system. One or more tables which list respective costs to reboot the components and respective likelihoods that reboots of the respective components will correct respective problems with the computer system are generated. Each of the costs is based on a time to reboot or delays caused by the reboot of the respective component. In response to a subsequent problem with the computer system, an order to reboot components of the computer system is determined from the table based on the costs and likelihoods that the reboot will correct the problem, such that a component of the computer system characterized by a relatively low cost and high likelihood to correct the problem will be rebooted before another component characterized by a relatively high cost and low likelihood to correct the problem. The tables are updated through actual experience.

US Classification:

392386, 118667

Abstract:

A bubbler chamber assembly comprising one chamber or two or more chambers connected in series, all chambers being in substantially vertical orientation. A solid or liquid source of the compound is contained in the chamber or chambers. The ratio between the length of the chamber or combined length of chambers connected in series with respect to the direction of flow of the carrier gas through the chamber or chambers and the average diameter equivalent of the cross section of the chamber or chambers with respect to the direction of flow of the carrier gas through the chamber or chambers is not less than about 6:1.

International Classification:

C07F 506

US Classification:

556179

Abstract:

Polymethylaluminoxane compositions having increased solution stability in organic solvent and, in some cases, increased polymerization activity, which comprise moieties derived from an organic compound containing an electron-rich heteroatom (e. g. , from Group V and/or Group VI of the Periodic Table) and a hydrocarbyl moiety. These compositions can be formed by reaction of trimethylaluminum, the organic compound, and water. They can also be formed by reaction of pre-formed polymethylaluminoxane the organic compound, which can be a hydrocarbyl group-containing compound containing an electron-rich heteroatom (e. g. , oxygen, nitrogen, or sulfur), either with or without an active hydrogen atom connected to the heteroatom. The organic compound, in some embodiments, has also been found to be effective in increasing the catalytic activity of modified polymethylaluminoxane which, in addition to methyl, contain C. sub. 2 and higher alkyl groups for enhanced solution stability.
