    摘要: A semiconductor device is made by steps of removing portions of a first capping layer, removing portions of a sacrificial layer, recessing sidewalls, and forming fin structures. The step of removing portions of the first capping layer forms a first capping structure that covers portions of the sacrificial layer. The step of removing portions of the sacrificial layer removes portions of the sacrificial layer that are not covered by the first capping structure to define an intermediate structure. The step of recessing the sidewalls recesses sidewalls of the intermediate structure relative to edge regions of the first capping structure to form a sacrificial structure having recessed sidewalls. The step of forming fin structures forms fin structures adjacent to the recessed sidewalls.

    摘要: There is a method for forming a semiconductor device. Portions of a sacrificial layer are removed to expose a first seed layer region. The first seed layer region corresponds to a first semiconductor region, and a remaining portion of the sacrificial layer corresponds to a second semiconductor region. An epitaxial semiconductor material is deposited over the first seed layer region. A capping layer is formed to overlie the epitaxial semiconductor material and the remaining portion of the sacrificial layer. Portions of the capping layer are removed to form a capping structure that overlies a part of the remaining portion of the sacrificial layer. Portions of the sacrificial layer not covered by the capping structure are removed to form a sacrificial structure having sidewalls. Fin structures are formed adjoining the sidewalls by depositing a semiconductor material along the sidewalls. Portions of the capping structure are removed to expose portions of sacrificial layer between adjacent fin structures. Portions of the sacrificial material between the adjacent fin structures are removed.
