Molecular organic semiconductors have been printed (see Figure and cover) using direct, mask‐ and solvent‐free printing via microscopic sonic jets of hot nitrogen seeded with the vapor of the organic semiconductor. Ultrahigh deposition rates, pattern resolution of up to 1000 dpi, and a high‐performance pentacene thin‐film transistor (TFT) are demonstrated. The theory, simulation, and experiments of this new method—organic vapor jet printing—are discussed.
