    Abstract: A method of forming an overlay mark is provided. A plurality of photoresist patterns are formed on a substrate. Each of the photoresist patterns includes a first strip and a plurality of second strips arranged in parallel. The first strip crosses the second strips to form a fence shape. Further, there is a space between two adjacent photoresist patterns, and the space is fence-shaped. A plurality of islands are formed in each of the spaces to form dot type strip patterns. The photoresist patterns are removed, and the dot type strip patterns serve as the overlay mark.

    Abstract: An integrated alignment and overlay mark includes a pre-layer pattern for reticle-to-wafer registration implemented in an exposure tool, and a current-layer pattern incorporated with the pre-layer pattern. The pre-layer pattern and the current-layer pattern constitute an overlay mark for determining registration accuracy between two patterned layers on a semiconductor wafer.

    Abstract: A mask overlay method, and a mask and a semiconductor device using the same are disclosed. According to the disclosed mask overlay technique, test marks and front layer overlay marks corresponding to a plurality of overlay mark designs are generated in a first layer of a semiconductor device. The test patterns generating the test marks each include a first sub pattern and a second sub pattern. Note that the first sub pattern has the same design as a front layer overlay pattern (which generates the front layer overlay mark corresponding thereto). Based on the test marks, performances of the plurality of overlay mark designs are graded. The front layer overlay mark corresponding to the overlay mark design having the best performance is regarded as an overlay reference for a mask of a second layer of the semiconductor device.
