摘要:
An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition includes a dielectric material, a crosslinking agent, and a thermal acid generator. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric material. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases. The thermal acid generator allows the dielectric layer to be cured at relatively lower temperatures and/or shorter time periods, permitting the selection of lower-cost substrate materials that would otherwise be deformed by the curing of the dielectric layer.

Methods of adding substituents to a benzodithiophene are disclosed. A benzodithiophene is reacted with a reagent to directly add the substituent to the benzene core of the benzodithiophene. This method eliminates steps from prior process and eliminates the need for hydrogenation, allowing for a safer and more scaleable process. The resulting benzodithiophenes are suitable for use in semiconductor polymers and have no loss of performance.

An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition comprises a dielectric material and a low surface tension additive. The low surface tension additive allows for the formation of a thin, smooth dielectric layer with fewer pinholes and enhanced device yield. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric material. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases.
