Towards flexible organic thin film transistors (OTFTs) for biosensing [PDF]

Journal of Materials Chemistry B, 2013
We have studied parylene-N and parylene-C for their use as substrates and gate dielectrics in OTFTs. Parylene-N films with a thickness of 300 nm show the required dielectric properties, as verified by breakthrough-voltage measurements. The surface roughness measured for 300 nm thick parylene-N films is 4-5 nm.
