  • Patent number: 8688910
    Abstract: A data processing system has a cache which receives both non-debug snoop requests and debug snoop requests for processing. The non-debug snoop requests are generated in response to transactions snooped from a system interconnect. Debug control circuitry that is coupled to the cache provides the debug snoop requests to the cache for processing. The debug snoop requests are generated in response to debug snoop commands from a debugger and without the use of the system interconnect. In one form snoop circuitry has a snoop request queue having a plurality of entries, each entry for storing a snoop request. A debug indicator corresponding to each snoop request indicates whether the snoop request is a debug snoop request or a non-debug snoop request.

  • Publication number: 20140086277
    Abstract: A thermal sensor system which includes a thermal sensor and a voltage control network which applies a reference voltage level and a delta voltage level to the same or different thermal sensors. The thermal sensor develops a reference current signal in response to the reference voltage level and a delta current signal in response to the delta voltage level. A current gain network adjusts gain of the delta current signal. A current compare sensor, which is responsive to the reference current signal and the delta current signal, provides a comparison metric. A controller controls the current gain network to adjust gain of the delta current signal while monitoring the comparison metric to determine a gain differential value indicative of a current ratio between the current signals. The controller determines a temperature value based on the gain differential value. A LUT may be used to retrieve the temperature.

  • Publication number: 20140087550
    Abstract: Embodiments include methods of making semiconductor devices with low leakage Schottky contacts. An embodiment includes providing a partially completed semiconductor device including a substrate, a semiconductor on the substrate, and a passivation layer on the semiconductor, and using a first mask, locally etching the passivation layer to expose a portion of the semiconductor. Without removing the first mask, a Schottky contact is formed of a first material on the exposed portion of the semiconductor, and the mask is removed. Using a further mask, a step-gate conductor of a second material electrically coupled to the Schottky contact is formed overlying parts of the passivation layer adjacent to the Schottky contact. By minimizing the process steps between opening the Schottky contact window in the passivation layer and forming the Schottky contact material in this window, the gate leakage of a resulting field effect device having a Schottky gate may be substantially reduced.

  • Patent number: 8680615
    Abstract: A customized shield plate field effect transistor (FET) includes a semiconductor layer, a gate dielectric, a gate electrode, and at least one customized shield plate. The shield plate includes a conductive layer overlying a portion of the gate electrode, one of the gate electrode sidewalls, and a portion of the substrate adjacent to the sidewall. The shield plate defines a customized shield plate edge at its lateral boundary. A distance between the customized shield plate edge and the sidewall of the gate electrode varies along a length of the sidewall. The customized shield plate edge may form triangular, curved, and other shaped shield plate elements. The configuration of the customized shield plate edge may reduce the area of the resulting capacitor and thereby achieve lower parasitic capacitance associated with the FET. The FET may be implemented as a lateral diffused MOS (LDMOS) transistor suitable for high power radio frequency applications.
