Hexagonal micrometer‐sized organic single crystals of a fused‐ring thienoacene are grown controllably by physical vapor transport over a large area. A “two‐dimensional organic‐ribbon mask” technique is developed to fabricate organic field‐effect transistors based on an individual microcrystal. The accomplished transistors exhibit mobility as high as 1.8 cm 2 V −1 s −1 with on/off ratios of typically >10 7 .
