The types of organic semiconductors are divided into two sub-groups of small molecules. Each polymer has its pros and cons. a small molecule Generally, it is easy to clean up and can be handled on a high load basis. Manufacture of high performance ﬁdening toolsﬁ multi-layer devices. Manufacturing high vacuum Electronics have limited cost and scalability at low speeds. Polymeric semiconductors can be liquidated towards larger substrates. Compatible with many printing technologies, it is fast and cost-costeffective. The advantage of manufacturing large boards is that they are more difficult to make. Complex manufacturing of refined and underlying multi-layer devices, It can be dissolved by the treatment of the top layer.
