    Abstract: A non-planar semiconductor structure includes raised semiconductor structures, e.g., fins, having epitaxial structures grown on top surfaces thereof, for example, epitaxial silicon naturally growing into a diamond shape. The surface area of the epitaxial structure may be increased by removing portion(s) thereof. The removal may create a multi-head (e.g., dual-head) epitaxial structure, together with the neck of the raised structure resembling a Y-shape. Raised structures that are not intended to include an epitaxial structure will be masked during epitaxial structure creation and modification. In addition, in order to have a uniform height, the filler material surrounding the raised structures is recessed around those to receive epitaxial structures.

    Abstract translation: 非平面半导体结构包括凸起的半导体结构,例如具有在其顶表面上生长的外延结构的翅片,例如外延硅自然生长成菱形。 可以通过去除外延结构的部分来增加外延结构的表面积。 移除可以与类似于Y形的凸起结构的颈部一起形成多头(例如双头)外延结构。 在外延结构的制造和修改过程中,不会包含外延结构的凸起结构将被掩蔽。 此外,为了具有均匀的高度,围绕凸起结构的填充材料围绕接收外延结构的填充材料凹入。
