  • Patent number: 9588800
    Abstract: The invention provides an enhanced two phase commit process to perform a transaction started by an application program and involving access to one or more resources managed by respective resource managers. The method comprises the steps of: enlisting the resource managers participating in the transaction, said enlisting step including associating a priority rank with each identified resource manager based on predefined priority rules; sending a prepare signal to said enlisted resource managers to begin the process of committing the transaction; and if a ready signal is received from all resource managers in response to the prepare signal, committing the resource managers in the order defined from the priority ranks associated with the resource managers.

  • Patent number: 8791021
    Abstract: Polycrystalline silicon germanium (SiGe) can offer excellent etch selectivity to silicon during cryogenic deep reactive ion etching in an SF6/O2 plasma. Etch selectivity of over 800:1 (Si:SiGe) may be achieved at etch temperatures from ?80 degrees Celsius to ?140 degrees Celsius. High aspect ratio structures with high resolution may be patterned into Si substrates using SiGe as a hard mask layer for construction of microelectromechanical systems (MEMS) devices and semiconductor devices.
