Abstract: The present invention disclosed a method for calculating an oscillation damping ratio of a power grid, and relates to the field of power system operation and control. When a power system oscillates, an oscillation period, two oscillation extreme points, and an oscillation direct current component start to be detected. Then an oscillation decay time constant is calculated according to the two oscillation extreme points and the oscillation direct current component. The oscillation damping ratio is calculated through the oscillation decay time constant and the oscillation period. Compared with a conventional fitting method, the conventional fitting method cannot calculate and analyze the oscillation damping ratio in a cast that a complete oscillation waveform is not obtained. The method proposed by the present inventive patent may complete the calculation of the oscillation damping ratio in a case of obtaining 2 pieces of data, so as to accelerate the speed of calculation.

Abstract: As feature sizes of semiconductor chips shrink there is a need for tighter overlay between layers in a lithography process. This means more advanced and larger overlay corrections may be necessary to ensure that die are properly manufactured into chips, especially in reconstituted substrates where the die can shift in the process of creating the substrate. Systems and methods for correcting these overlay errors in a lithographic process are provided. Additional rotation (theta) and projected image size (mag) corrections can be made to correct overlay errors present in reconstituted substrates by adjusting the stage and the reticle. Furthermore, these adjustments can be made allowing site-by-site or zone-by-zone corrections instead of a one-time adjustment of the reticle chuck as has been done in the past. These corrections can alleviate some of the issues associated with fan-out wafer-level packaging (FOWLP) and fan-out panel-level packaging (FOPLP).
