  • Publication number: 20080221266
    Abstract: The invention pertains to a process to polymerize one or more monomers wherein one or more initiators and optionally one or more surfactants are added to a polymerization mixture when the pressure in the polymerization reactor is dropping. This process allows a shorter polymerization time due to a higher pressure drop rate at the end of the polymerization reaction. Moreover, the cooling capacity of the polymerization reactor is used more efficiently.

  • Patent number: 7387815
    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.
