摘要:
The present invention relates to systems and methods for measuring misalignment between layers of a semiconductor device. In one embodiment, a method includes applying an input voltage to respective ones of one or more first electrodes associated with a first conductive layer of a semiconductor device; sensing an electrical property of one or more second electrodes associated with a second conductive layer of the semiconductor device in response to applying the input voltage to the respective ones of the one or more first electrodes; and calculating a misalignment between the first conductive layer of the semiconductor device and the second conductive layer of the semiconductor device in an in-plane direction as a function of the electrical property of the one or more second electrodes.
