Abstract: By removing an outer spacer of a transistor element, used for the formation of highly complex lateral dopant profiles, prior to the formation of metal silicide, employing a wet chemical etch process, it is possible to position a stressed contact liner layer more closely to the channel region, thereby allowing a highly efficient stress transfer mechanism for creating a corresponding strain in the channel region, without affecting circuit elements in the P-type regions.

Abstract: A system and method for efficient garbage collection. A general-purpose central processing unit (CPU) sends a garbage collection request and a first log to a special processing unit (SPU). The first log includes an address and a data size of each allocated data object stored in a heap in memory corresponding to the CPU. The SPU has a single instruction multiple data (SIMD) parallel architecture and may be a graphics processing unit (GPU). The SPU efficiently performs operations of a garbage collection algorithm due to its architecture on a local representation of the data objects stored in the memory. The SPU records a list of changes it performs to remove dead data objects and compact live data objects. This list is subsequently sent to the CPU, which performs the included operations.
Abstract: A graphics processor or a graphics block for use in a processor includes a type buffer used for determining if a currently processed pixel requires further processing. Each pixel has a number of sub-pixels and each sub-pixel line includes at least one counter that is stored in an edge buffer. A limited edge buffer that can store edge buffer values in a limited range can be employed. Each buffer can include information regarding the whole screen or a portion of thereof. The edge buffer also can be an external or internal buffer, and when implemented internally, the graphics processor or graphics block need not employ a bi-directional bus.
Abstract: By forming metallization structures on the basis of an imprint technique, in which via openings and trenches may be commonly formed, a significant reduction of process complexity may be achieved due to the omission of at least one further alignment process as required in conventional process techniques. Furthermore, the flexibility and efficiency of imprint lithography may be increased by providing appropriately designed imprint molds in order to provide via openings and trenches exhibiting an increased fill capability, thereby also improving the performance of the finally obtained metallization structures with respect to reliability, resistance against electromigration and the like.

Abstract: By combining an anneal process for adjusting the effective channel length and a substantially diffusion-free anneal process performed after a deep drain and source implantation, the vertical extension of the drain and source region may be increased substantially without affecting the previously adjusted channel length. In this manner, in SOI devices, the drain and source regions may extend down to the buried insulating layer, thereby reducing the parasitic capacitance, while the degree of dopant activation and thus series resistance in the extension regions may be improved. Furthermore, less critical process parameters during the anneal process for adjusting the channel length may provide the potential for reducing the lateral dimensions of the transistor devices.

Abstract: A system and method using messages to access registers and memory in a PCI Express communications link environment. Vendor defined PCI Express messages can be used to read and write to the memory-mapped or register space of a device. Four types of accesses are defined using this messaging approach, namely memory read, memory write, configuration read and configuration write. The type of register access desired is defined by the appropriate value in a vendor-specific type field in the header of the vendor defined message. If a PCI Express compliant device at the other end of the PCI Express link does not support these types of messages, the messages are silently discarded by the receiver and no error is reported.

Abstract: A method for transitioning power states in a device includes designating a first reduced power state as a target power state. A first expected residency for the target power state is determined based on a counting of activity requests associated with the device. The device is transitioned to the target power state responsive to the expected residency satisfying a first predetermined threshold.

Abstract: The present invention provides a method of forming a transistor. The method includes forming a first layer of a first semiconductor material above an insulation layer. The first semiconductor material is selected to provide high mobility to a first carrier type. The method also includes forming a second layer of a second semiconductor material above the first layer of semiconductor material. The second semiconductor material is selected to provide high mobility to a second carrier type opposite the first carrier type. The method further includes forming a first masking layer adjacent the second layer and etching the second layer through the first masking layer to form at least one feature in the second layer. Each feature in the second layer forms an inverted-T shape with a portion of the second layer.
Abstract: In sophisticated semiconductor devices including copper-based metallization systems, a substantially aluminum-free bump structure in device regions and a substantially aluminum-free wire bond structure in test regions may be formed on the basis of a manufacturing process resulting in identical final dielectric layer stacks in these device areas. The number of process steps may be reduced by making a decision as to whether a substrate is to become a product substrate or test substrate for estimating the reliability of actual semiconductor devices. For example, nickel contact elements may be formed above copper-based contact areas wherein the nickel may provide a base for wire bonding or forming a bump material thereon.

Abstract: A receiver employs iterative decoding of packet data, where the packet data represents a data frame encoded with at least two logical dimensions. A logical dimension refers to a layer, or sub-layer, of a layered network architecture. Consequently, a first logical dimension of encoding might refer to error detection in a packet frame at the data link layer, while a second logical dimension of coding might refer to error detection/correction encoding at a physical layer. For example, a data frame might be divided into several packets, each with a corresponding cyclic redundancy check (CRC) value as coding in the first logical dimension, which are then transmitted with a convolutional code as coding in the second logical dimension. The receiver performs iterative decoding in the first and second logical dimensions until either i) all errors are identified and corrected or ii) another type of stopping condition is met.
