摘要： One embodiment of the present invention provides a system that verifies an integrated circuit (IC) chip layout. During operation, the system receives a layout of an IC chip after the layout has gone through a place-and-route operation. Next, the system performs a lithography compliance checking (LCC) operation on the layout to detect lithography hotspots within the layout, wherein each lithography hotspot is associated with a local routing pattern around the lithography hotspot. Next, for each detected lithography hotspot, the system compares the associated local routing pattern against a hotspot database to determine if the local routing pattern matches an entry in the hotspot database, which stores a set of known hotspot configurations. If so, the system corrects the lithography hotspot using correction guidance information associated with the hotspot configuration stored in the hotspot database. Otherwise, the system corrects the lithography hotspot by performing a local rip-up and reroute on the local routing pattern, iteratively, until achieving convergence or given number of iterations.
摘要翻译：本发明的一个实施例提供一种验证集成电路（IC）芯片布局的系统。在操作过程中，系统在布局经过布线操作后接收IC芯片的布局。接下来，系统在布局上执行光刻柔性检查（LCC）操作以检测布局内的光刻热点，其中每个光刻热点与光刻热点周围的局部布线图案相关联。接下来，对于每个检测到的光刻热点，系统将相关联的本地路由模式与热点数据库进行比较，以确定本地路由模式是否匹配热点数据库中存储一组已知热点配置的条目。如果是，则系统使用与存储在热点数据库中的热点配置相关联的校正指导信息来校正光刻热点。否则，系统通过对本地路由模式执行局部的rip-up和重新路由来迭代地校正光刻热点，直到达到收敛或给定的迭代次数。

摘要： One embodiment of the present invention provides a system that generates a pattern-clip-based hotspot database for performing automatic pattern-clip-based layout verification. During operation, the system receives a list of pattern clips which specify manufacturing hotspots to be avoided in a layout, wherein each pattern clip comprises a set of geometries in proximity to each other. Next, for each pattern clip, the system perturbs the pattern clip to determine a first range of variations for the constituent set of geometries wherein the perturbed pattern clip no longer causes a manufacturing hotspot. The system then extracts a set of correction guidance descriptions from the first range of variations for correcting the pattern clip. Subsequently, the system stores the pattern clip and the set of correction guidance descriptions in the pattern-clip-based hotspot database.

摘要： One embodiment of the present invention provides a system that automatically processes manufacturing hotspot information. During operation, the system receives a pattern clip associated with a manufacturing hotspot in a layout, wherein the pattern clip comprises a set of polygons in proximity to the manufacturing hotspot's location. Next, the system determines if the pattern clip matches a known manufacturing hotspot configuration. If the pattern clip does not match a known manufacturing hotspot configuration, the system then performs a perturbation process on the pattern clip to determine a set of correction recommendations to eliminate the manufacturing hotspot. By performing the perturbation process, the system additionally determines ranges of perturbation to the set of polygons wherein the perturbed pattern clip does not eliminate the manufacturing hotspot. Subsequently, the system stores the set of correction recommendations and the ranges of perturbation into a manufacturing hotspot database.

摘要： A method for performing layout verification involves identifying feature centerlines in a mask layout, and then performing lithography simulation along the centerlines to generate a set of intensity distributions. At each local maxima or minima in the intensity distributions, further lithography simulation can be performed to determine an exposure pattern width at those local maxima/minima (check positions). The exposure pattern widths can then be evaluated to determine whether an actual pinch or bridge defect will be generated at those locations. If defect generation is likely (based on the lithographical simulation) at a particular location, the corresponding portion of the mask layout can be redesigned to avoid defect generation during actual production. In this method, accurate layout verification can be performed with a minimum of time-consuming lithography modeling.

摘要： In a method of entering text into an electronic communications device by means of a keypad having a number of keys, each key representing a plurality of letters and/or phonetic symbols, entered text is displayed on a display on the device. Possible phonetic syllables corresponding to an activated key sequence are generated. These are compared with a stored vocabulary comprising syllables and corresponding characters occurring in a given language. Those stored syllables and corresponding characters that match the possible syllables are pre-selected; and a number of these are presented in a separate first graphical object arranged predominantly on the display. Characters corresponding to one of the syllables in the first object are simultaneously presented in a second graphical object. Thus, there is provided a way of entering text with characters having a phonetic representation by means of keys representing a plurality of letters or phonetic symbols, which may be easier to use even in the case where a phonetic syllable corresponds to several characters.
