20090193374 | METHOD OF DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE, DESIGNING APPARATUS, AND SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - As a method for considering the adverse influence of the stresses caused form the pad, two sorts of methods are provided. As one method, while delay variation values of cells caused by an adverse influence of stresses are calculated, the calculated delay variation values are applied to the cells so as to perform a timing analysis, and the like by considering the adverse influence of the stresses. Then, in order that a flip chip type LSI is designed by employing a result of the above-described analysis in such a manner that the adverse influence of the stresses applied from the pad is not given to vias, wiring lines, and cells located under the pad, such a physical structure that no via is arranged under the pad is employed. | 07-30-2009 |
20100148218 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE AND METHOD FOR DESIGNING THE SAME - The layout of an LSI is previously designed so that cells below pads which will be affected by stress are arranged so that the occurrence of a malfunction of the LSI which will be caused by the influence of stress is reduced or prevented. In addition to or instead of the cell arrangement, the arrangement of pads, bumps or the like may be adjusted. | 06-17-2010 |
