Laser Induced Forward Transfer (LIFT) is a widely used technique for elegant deposition and patterning of various materials (eg. Metals, oxides, organic substances and even biological material). The most typical attribute of LIFT technique (as presented by many authors) is utilization of short laser pulses with duration from ps to tens of ns with very high energy per pulse. Such approach requires of usage of expensive laser sources. Our work is focused to alternative instrumentation of LIFT - possibilities of usage of continuous wave (CW) lasers for local deposition and patterning of organic semiconductors. The source substrates were prepared as follows: Thin glass slides with sputtered metal layer (gold, platinum, copper, silver - thickness ~ 100 nm) were cleaned and dried. Side with sputtered metal was then covered with a thin layer of purified organic semiconductors - Perylene, Perylene anhydride, Zn and Sm Phthalocyanines.
