    摘要: A photolithographic method uses different exposure patterns. In one aspect, a photo-sensitive layer on a substrate is subject to a first exposure using optics having a first exposure pattern, such as an x-dipole pattern, followed by exposure using optics having a second exposure pattern, such as a y-dipole pattern, via the same mask, and with the photo-sensitive layer fixed relative to the mask. A 2-D post pattern with a pitch of approximately 70-150 nm may be formed in a layer beneath the photo-sensitive layer using 157-193 nm UV light, and hyper-numerical aperture optics, in one approach. In another aspect, hard baking is performed after both of the first and second exposures to erase a memory effect of photoresist after the first exposure. In another aspect, etching of a hard mask beneath the photo-sensitive layer is performed after both of the first and second exposures.

    摘要: Searcher hardware is multiplexed to perform simultaneous searches in either an IS-95 CDMA mode or a GPS mode. In the IS-95 mode, the search hardware is time-multiplexed into a number of searcher time slices, each of which can generate a PN sequence to despread a data sequence. In the GPS mode, the search hardware is configured as a number of distinct GPS channels, each of which can generate a Gold code sequence for tracking a GPS signal from a particular GPS satellite. This configuration allows the searcher to perform multiple GPS signal searches simultaneously. Signal searching in both IS-95 and GPS modes is performed at significantly higher speeds compared to conventional searcher hardware. Moreover, the search hardware can be dynamically configured to operate in either the IS-95 or the GPS mode, eliminating the need for dedicated circuitry for each mode of operation.

    摘要: A method creates pillar structures on a semiconductor wafer and includes the steps of providing a layer of semiconductor. A layer of photoresist is applied over the layer of semiconductor. The layer of photoresist is exposed with an initial pattern of light to effect the layer of photoresist. The photoresist layer is then etched away to provide a photoresist pattern to create the pillar structures. The photoresist pattern is processed in the layer of photoresist after the step of exposing the layer of photoresist and prior to the step of etching to reduce the dimensions of the photoresist pattern in the layer of photoresist.

    摘要: A method and system for inputting Chinese characters from an English keyboard into a computer. The invention is implemented via a software application that runs on a computer to which a physical or virtual keyboard device is connected. The software application has a database of English character sequences each of which is associated with a Chinese character. The software application captures character sequences generated by the user operating the keyboard, and searches its database for matches to the captured sequence.
