  • Patent number: 11189523
    Abstract: A method of forming a semiconductor structure includes the following steps. A dielectric layer is formed over a conductive line. A photoresist layer is formed over the dielectric layer. The photoresist layer is patterned to form a mask feature and an opening is defined by the mask feature. The opening has a bottom portion and a top portion communicated to the bottom portion, and the top portion is wider than the bottom portion. The dielectric layer is etched to form a via hole in the dielectric layer using the mask feature as an etch mask, such that the via hole has a bottom portion and a tapered portion over the bottom portion. The conductive material is filled in the via hole to form a conductive via.
