  • Patent number: 8099694
    Abstract: In an example embodiment, an EDA program receives input which includes a selection as to an FPGA die and its device package and a selection as to a structured ASIC die and its device package. If the I/O pins on the device package for the FPGA differ from the I/O pins on the device package for the structured ASIC, the EDA program determines a correspondence between the I/O pins on the two device packages (e.g., by identifying the location of the pads for I/O pins on the structured ASIC die and/or creating a virtual structured ASIC device package whose I/O pins are a superset of the I/O pins on the selected structured ASIC device package), which determination includes checking rules for resource assignments. The EDA program then stores the determined correspondence in a device database where the determined correspondence can be accessed by CAD algorithms.

  • Patent number: 8087081
    Abstract: A client computer may be configured to perform computer security operation services, such as malicious code scanning and protection against online threats, using one of several remotely located server computers. The client computer may be configured to determine an operational state of the server computers and determine a protection status of the client computer resulting from use of a server computer of a particular operational state. The protection status may have one of at least three levels and indicate vulnerability of the client computer. The client computer may determine the operational state of a server computer based on available bandwidth for network communication between the client computer and the server computer. The client computer may be configured to allow for automatic or manual selection of another server computer when the currently selected server computer results in the client computer having a protection status below a threshold level.

  • Publication number: 20110183508
    Abstract: A structure and method for replacement metal gate technology is provided for use in conjunction with semiconductor fins or other devices. An opening is formed in a dielectric by removing a sacrificial gate material such as polysilicon. The surfaces of the semiconductor fin within which a transistor channel is formed, are exposed in the opening. A replacement metal gate is formed by forming a diffusion barrier layer within the opening and over a gate dielectric material, the diffusion barrier layer formation advantageously followed by an in-situ plasma treatment operation. The treatment operation utilizes at least one of argon and hydrogen and cures surface defects in the diffusion barrier layer enabling the diffusion barrier layer to be formed to a lesser thickness. The treatment operation decreases resistivity, densifies and alters the atomic ratio of the diffusion barrier layer, and is followed by metal deposition.

  • Publication number: 20110151655
    Abstract: The present disclosure provides various methods of fabricating a semiconductor device. A method of fabricating a semiconductor device includes providing a semiconductor substrate and forming a gate structure over the substrate. The gate structure includes a first spacer and a second spacer formed apart from the first spacer. The gate structure also includes a dummy gate formed between the first and second spacers. The method also includes removing a portion of the dummy gate from the gate structure thereby forming a partial trench. Additionally, the method includes removing a portion of the first spacer and a portion of the second spacer adjacent the partial trench thereby forming a widened portion of the partial trench. In addition, the method includes removing a remaining portion of the dummy gate from the gate structure thereby forming a full trench. A high k film and a metal gate are formed in the full trench.
