Abstract
Techniques for disposing an organic semiconductor film on a receiver substrate, comprising the steps of: depositing an organic semiconductor film onto a donor substrate, the semiconductor film having a first surface facing the donor substrate and having an exposed second surface; bringing the exposed second surface adjacent a receiver substrate such that the semiconductor film is in contact with both substrates; and then, moving the donor and receiver substrates apart; and wherein a surface portion of the receiver substrate is maintained above its glass transition during the moving step. Active organic semiconductor devices.
Claims19
A process for disposing an organic semiconductor film on a receiver substrate, comprising the steps of:
- depositing an organic semiconductor film onto a donor substrate, said semiconductor film having a first surface facing said donor substrate and having an exposed second surface;
- bringing the exposed second surface adjacent a receiver substrate such that the semiconductor film is in contact with both substrates;
- and
- then, moving the donor and receiver substrates apart;
- and
- wherein a surface portion of the receiver substrate is maintained above its glass transition during the moving step.
An active organic semiconductor device comprising:
- a receiver substrate;
- and
- an organic semiconductor film on said receiver substrate, said semiconductor film having a smooth surface facing away from said receiver substrate;
- said receiver substrate having a glass transition occurring at a temperature within a range of between about 280° Kelvin and about 300° Kelvin.
