Abstract: The present invention provides a method of fabricating a microelectronics device. In one aspect, the method comprises forming a spacer material 160 over gate electrodes 150 that are, in turn, located over a microelectronics substrate 110. The gate electrodes 150 have a doped region 170a located between them. A portion of the spacer material 160 is removed with a chemical/mechanical process using a slurry that is selective to a portion of the spacer material 160. The method further comprises etching a remaining portion of the spacer material 163, 165, 168 to form spacer sidewalls 163, 165, 168 on the gate electrodes 150. The etching exposes a surface of the gate electrodes 150 and leaves a portion of the spacer material 168 over the doped region 170a. Metal is then incorporated into the gate electrodes 150 to form silicided gate electrodes 150.
Abstract: A system comprises a main stack, a local data stack and plurality of flags. The main stack comprises a plurality of entries and is located outside a processor's core. The local data stack is coupled to the main stack and is located internal to the processor's core. The local data stack has a plurality of entries that correspond to entries in the main stack. Each flag is associated with a corresponding entry in the local data stack and indicates whether the data in the corresponding local data stack entry is valid. The system performs two instructions. One instruction synchronizes the main stack to the local data stack and invalidates the local data stack, while the other instruction synchronizes the main stack without invalidating the local data stack.
Abstract: For a given lookup table, maximum and minimum values of index values are determined. The lookup table is expanded in both directions by replicating the lowest and highest values to take care of these maximum and minimum values. This reduces the rendering clock count for each pixel.
Abstract: In packet communications, one existing address code in a predetermined address field (AM_ADDR) of a packet can be used to indicate that bits in another field (TYPE) of the packet represent additional address information. Additional address information can also be provided for by extending the length of the predetermined address field.

Abstract: This invention provides trace address compression by comparing respective bytes of a current trace address with a stored comparison address. Only the least significant bytes of the current trace address that do not match the comparison address or are less significant than any section of the current trace address that does not match the comparison address are transmitted. This sometimes reduces the amount of data that needs to be transmitted. The comparison address is specified by a central processing unit via a memory mapped register write operation.

Abstract: A method of eliminating the non-linearities associated with the remote feedback sensor, such as a quad position detector, used in a micro-electro-mechanical (MEM) mirror assembly. The incoming beam transmitted from a remote optical wireless link is first polarized, and then a single detector is employed to detect the polarization for the receiver. The single detector eliminates the non-linearity associated with a quad position detector, since the space between the quad detectors is eliminated.
Abstract: Encoder circuitry for applying a low-density parity check (LDPC) code to information words is disclosed. The encoder circuitry takes advantage of a macro matrix arrangement of the LDPC parity check matrix in which a left-hand portion of the parity check matrix is arranged as an identity macro matrix, each entry of the macro matrix corresponding to a permutation matrix having zero or more circularly shifted diagonals. The encoder circuitry includes a cyclic multiply unit, which includes a circular shift unit for shifting a portion of the information word according to shift values stored in a shift value memory for the matrix entry, and a bitwise exclusive-OR function for combining the shifted entry with accumulated previous values for that matrix entry. Circuitry for solving parity bits for row rank deficient portions of the parity check matrix is also included in the encoder circuitry.
Abstract: The invention relates to a method to increase the visibility of effective address computation in pipelined architectures. In this method, the current effective address delay of each instruction in the pipeline is calculated. The current effective address delay is used to determine if a valid effective address is available for each instruction. If a valid effective address for an instruction is not available, it is computed if possible.

Abstract: The invention relates to a method of inspecting a mask comprising the steps: patterning a semiconductor material with a reference mask, patterning the semiconductor material with the mask as the inspection item, inspecting both patterns on the semiconductor material by means of an apparatus suitable for inspecting the semiconductor material, and comparing the pattern generated by the inspection item mask to the pattern generated by the reference mask to detect deviations in the inspection item mask from the reference mask. The invention is particularly suitable for reticule inspection. When a semiconductor wafer is multiply patterned by the reference mask and the inspection item mask alternatingly side-by-side, deviations in the reticules are evident as recurrent discrepancies between the patterns on the wafer.

Abstract: In a semiconductor flip-chip package having a semiconductor die as part of a substrate assembly, a lid (or lid assembly) and substrate are supported to prevent tilting and teetering of the lid. The lid and substrate do not adhere, so as to reduce cracking of solder joints due to thermal cycling induced by repeated system power on-off. An adhesion prohibitor may be applied so that a support does not adhere to both lid and substrate; the support may be prevented from adhering to both lid and substrate by a separate curing step. The arrangements and fabrication methods may be applied to many package types, including ball grid array (BGA) and land grid array (LGA) packages.
Abstract: A digital storage element comprises a master transparent latch that receives functional data signals from data input ports and scan data signals from a scan input port. The data input ports are coupled to a two-input, one-output multiplexer adapted to receive the functional data signals and to selectively output one of the functional data signals. The digital storage element also comprises a slave transparent latch coupled to the master transparent latch, the slave transparent latch comprising dedicated functional data and scan data output ports. While operating in a scan mode, a first clock signal is used by the slave transparent latch and a second clock signal is used by the master transparent latch, wherein the first and second clock signals are non-overlapping.

Abstract: A method and system of indexing into trace data based on entries in a log buffer. At least some of the illustrative embodiments are methods comprising executing a traced program on a target device. The traced program writes entries to a log buffer within the target device, and the traced program also contemporaneously writes an index value for each entry to a register. The index value written to the register becomes part of trace data regarding the traced program and correlates each entry to a respective portion of the trace data. Using the information one may either or both: display on a display device a portion of the trace data (the portion selected based on selecting an entry from the log buffer); or display on the display a portion of the log buffer (the portion selected based on selecting an entry from the trace data).
