In this paper, we introduce Merck's general approach for the development of organic semiconductor
formulations. We focus on solution processable materials with the idea of developing industry-compatible
processes to enable mass market penetration. We give examples of Merck's formulations achieving
reproducible mobilities in the region of 2 cm<sup>2</sup>/Vs in BG OTFT.
We review the importance of process development for a specific application, giving examples of
supporting materials and formulations needed to facilitate usage, which covers dielectric development.
