    Abstract: A patterning method and a patterned material layer are provided. After providing a substrate including a material layer, a hard mask layer including trenches extending in a first direction is formed over the material layer. A filling material layer is formed on the hard mask layer to cover the hard mask layer and fills in the trenches. A mask layer in a grid pattern is formed on the filling material layer. The mask layer includes first grid lines extending in the first direction and second grid lines extending in a second direction, and each of the underlying trench is located between two most adjacent first grid lines. The material layer is etched with the mask layer as an etching mask to form a patterned material layer including a plurality of first holes and a plurality of second holes.

    Abstract: Provided is a semiconductor device including a substrate and a stack layer. The substrate includes a first region, a second region, and a third region. The third region is disposed between the first region and the second region. Since a top surface of the substrate in the first region is lower than the top surface of the substrate in the second region, the substrate in the third region has a first step height. The stack layer is disposed on the substrate in the first and third regions. The top surface of the stack layer in the first region and the third region and the top surface of the substrate in the second region are substantially coplanar.

    Abstract: A method for forming an aligned mask comprises etching a reference mark on a substrate to demarcate a boundary of an etch region; forming an etch mask on the substrate, using an exposure setting, the etch mask having a boundary; and measuring a distance between the reference mark and the boundary. When the measured distance is outside a margin of a target distance, then the etch mask is removed from the substrate, the exposure setting is changed, a next etch mask is formed using the changed exposure setting, and said measuring is repeated. A set of reference marks can be etched on a top level in a set of levels to demarcate boundaries of etch regions. An etch-trim process can be performed to form steps in the set of levels, wherein the etch-trim process includes at least first and second etch-trim cycles using first and second reference marks.

    Abstract: An interconnect structure including a first dielectric layer, a first conductive layer, a second conductive layer, a capping layer, and a via is provided. The first dielectric layer has a first trench and a second trench. The first conductive layer is located in the first trench. The second conductive layer is located in the second trench, and a top surface of the second conductive layer is lower than a top surface of the first dielectric layer. The capping layer having a via opening exposing a portion of the first conductive layer covers the first dielectric layer, the first conductive layer, and the second conductive layer. The via located on the first conductive layer and the first dielectric layer located between the first conductive layer and the second conductive layer is filled into the via opening and electrically connected to the first conductive layer.
