Herein, we report a solid-state lithography technique utilizing the eutectic friction transfer (EFT). Eutectic friction transfer lithography (EFTL) technique employs the eutectic pellets made of semiconducting polymers and volatile organic solid matrixes. With utilizing frictional heating and eutectic melting, various semiconducting polymer cryastals formed by simple rubbing process at mild condition. Strong anisotropic optical properties suggest that <i>J</i>-type packing is dominant in EFTL microwires because of the highly extended and planarized crystal structures.
