We have studied nano-patterning of a two-dimensional material with ultrafine helium ion beam in the aspect of shape-, size- and damage-control. It reveals that the crystalline structure plays an important role in the shape-control. Instead of commonly circular-shaped nanopore, a spot irradiation onto a single layer of molybdenum disulfide (MoS2) gives rise to a rhombus-shaped nanopore, which is well explained by the sub-rhombus crystalline structure of MoS2. Helium ion beam also shows a promising capability of precisel
