Abstract
Disclosed are polymer-based dielectric compositions (e.g., formulations) and materials (e.g. films) and associated devices. The polymers generally include photocrosslinkable pendant groups; for example, the polymers can include one or more coumarin-containing pendant groups.
Claims21
1-21. (canceled)
A thin film transistor device, comprising:
- a dielectric layer;
- a semiconductor layer;
- a gate electrode;
- a source electrode;
- and
- a drain electrode;
- wherein the dielectric layer is disposed between the semiconductor layer and the gate electrode;
- wherein the source electrode and the drain electrode are in contact with the semiconductor layer,
- wherein the dielectric layer comprises a polymeric film, the polymeric film comprising a polymer comprising a repeating unit having a pendant group comprising an optionally substituted coumarin-6-yl moiety.
A vinyl polymer, polymerized from one or more vinyl monomers, wherein at least one of the vinyl monomers is vinyl phenol or a derivative of the vinyl phenol, and the vinyl polymer comprises a repeating unit having a pendant group comprising an optionally substituted coumarin moiety.
