摘要: A method of measuring overlay between a first structure and a second structure on a substrate is provided. The structures include equidistant elements, such as parallel lines, wherein the equidistant elements of the first and second structure alternate. A design width CD1 of the elements of the first structure is different from a design width CD2 of the elements of the second structure. The difference in design width can be used to identify measurement points having incorrectly measured overlay errors.

摘要: A method for providing a pattern on a substrate is disclosed. The method includes providing a first pattern in a first layer of photoresist and a first layer of bottom anti-reflective coating material on the substrate, etching the first pattern into the substrate, providing a second layer of photoresist and a second layer of bottom anti-reflective coating material on the substrate, providing a second pattern in the second layers of photoresist and bottom anti-reflective coating material, and etching the second pattern into the substrate, the first and second patterns on the substrate together defining the pattern.
