  • Patent number: 8546234
    Abstract: A semiconductor process is provided. A mask layer is formed on a substrate and has a first opening exposing a portion of the substrate. Using the mask layer as a mask, a dry etching process is performed on the substrate to form a second opening therein. The second opening has a bottom portion and a side wall extending upwards and outwards from the bottom portion, wherein the bottom portion is exposed by the first opening and the side wall is covered by the mask layer. Using the mask layer as a mask, a vertical ion implantation process is performed on the bottom portion. A conversion process is performed, so as to form converting layers on the side wall and the bottom portion of the second opening, wherein a thickness of the converting layer on the side wall is larger than a thickness of the converting layer on the bottom portion.
