• photonic platform was optimized from an initial value of 8.7% up to 65.5%, which is a 7.5-fold increase from the initial structure. The optical losses due to the LED–waveguide and waveguide–photodetector coupling were reduced by removing the spin-on-glass encapsulation layer and reducing the SiNx waveguide

Keywords: dielectric; encapsulation layer; flexible substrate; organic field effect transistor; Parylene C; Review Introduction An improvement of the performance of organic transistors by means of boosting charge-carrier mobility is one of the main quests in organic electronics, calling for novel design

• flexibility is a substrate that is not only flexible (relatively low Young's modulus) but also offers a smooth and pinhole-free structure. An equally important role is played by the encapsulation layer. Firstly, it protects the semiconductor thin film against the negative influence of water and oxygen

• transistors as both substrate and encapsulation layer. The present work is focused on the unique performance of one polymer material used in OFETs. This material is poly(chloro-p-xylylene) (Parylene C) the applicability of which in the field of OFET manufacturing appears to be continuously growing. Three
