Abstract: A semiconductor device includes a substrate having a fin structure extending along a first direction. The fin structure protrudes from a top surface of a trench isolation region and has a first height. A plurality of gate lines including a first gate line and a second gate line extend along a second direction and striding across the fin structure. The first gate line has a discontinuity directly above a gate cut region. The second gate line is disposed in proximity to a dummy fin region, and does not overlap with the dummy fin region. The fin structure has a second height within the dummy fin region, and the second height is smaller than the first height.

Abstract: A method of forming an overlay mark structure includes the following steps. An insulation layer is formed on a substrate. A first overlay mark is formed in the insulation layer. A metal layer is formed on the substrate. The metal layer covers the insulation layer and the first overlay mark. The metal layer on the first overlay mark is removed. A top surface of the first overlay mark is lower than a top surface of the insulation layer after the step of removing the metal layer on the first overlay mark. A second overlay mark is formed on the metal layer. In the method of forming the overlay mark structure, the first overlay mark may not be covered by the metal layer for avoiding influences on related measurements, and the second overlay mark may be formed on the metal layer for avoiding related defects generated by the height difference.

Abstract: A method for monitoring fin removal includes providing a substrate having a first region with first fins extending along a first direction and a second region with second fins extending along a second direction, wherein the first direction is perpendicular to the second direction; forming a material layer on the substrate to cover the first fins and the second fins; identically patterning the first fins and the second fins using a first pattern and a second pattern respectively for simultaneously removing parts of the first and second fins, thereby forming first fin features in the first region and second fin features in the second region, wherein the first pattern has a first dimension along the second direction, the second pattern has a second dimension along the second direction, and the second dimension is equal to the first dimension; and monitoring the first fin features using the second fin features.

Abstract: A measurement make includes four rectangular regions having a first region and a second region arranged diagonally, and a third region and a fourth region arranged diagonally. A plurality sets of first inner pattern blocks, first middle pattern blocks, and first outer reference pattern blocks, are disposed within the first region. Each first inner pattern block comprises line patterns and a block pattern. The block pattern has multiple space patterns arranged therein. The first inner pattern block is rotational symmetrical to the first middle pattern block.
