    Abstract: A mechanism and system are described for either releasing held resources in the case of a deadlock or to postpone requests for resources when a potential deadlock is detected. One technique involves a three pass algorithm for selecting a candidate, where the candidate is either a possessory entity or resource is used. The three passes are as follows: (1) determining the subset of candidates, which have the CAN-BE-VICTIM flag set on; (2) If pass one results in a subset with more than one candidates in it, process that subset to determine a second subset of candidates based on resource priority associated with a resource type; (3) If the second pass results in a subset with more than one candidate in it, process that subset to select the candidate that has been running or held the shortest length of time.

    Abstract: A method for creating and transporting low-energy ions for use in plasma processing of a semiconductor wafer is disclosed. In an exemplary embodiment of the invention, the method includes generating plasma from a gas species to produce a plasma exhaust. The plasma exhaust is then introduced into a processing chamber containing the wafer. The ion content of the plasma exhaust is enhanced by activating a supplemental ion source as the plasma is introduced into the processing chamber, thereby creating a primary plasma discharge therein. Then, the primary plasma discharge is directed into a baffle plate assembly, thereby creating a secondary plasma discharge exiting the baffle plate assembly. The strength of an electric field exerted on ions contained in the secondary plasma discharge is reduced. In so doing, the reduced strength of the electric field causes the ions to bombard the wafer at an energy insufficient to cause damage to semiconductor devices formed on the wafer.

    Abstract: Distortion and crosstalk that occurs when operating optical amplifiers in saturation is substantially reduced by passively compensating for gain variations caused by changes in input power to the optical amplifiers. More specifically, in an optical communication system having one or more optical amplifiers, a “reservoir” optical channel is supplied in addition to the other traffic-carrying optical channels. The wavelength of the reservoir channel is selected such that the power level of the reservoir channel varies in response to changes in power levels of the traffic-carrying channels. Because gain variations are typically highest around the gain peak region in an optical amplifier's gain bandwidth, the reservoir channel in one exemplary embodiment is assigned a wavelength around the gain peak region. As such, the reservoir channel can absorb or otherwise receive most of the distortion and crosstalk while the traffic-carrying channels located away from the gain peak region will experience less distortion and crosstalk. -Importantly, this passive compensation scheme can be used in an amplified system which is operating in the presence of nonlinear distortions caused by gain variations, such as inter-modal distortion and saturation induced crosstalk.

    Abstract: A wide band optical amplifier employing a split-band architecture in which an optical signal is split into several independent sub-bands which then pass in parallel through separate branches of the optical amplifier. Each branch may be optimized for the sub-band that traverses it. The independent sub-bands are combined before output, resulting in a broad band, high efficiency amplifier. Alternative, hybrid split-band amplifiers are described. As a result of their desirable characteristics, these wide band optical amplifiers may be used in dense WDM communications systems.
