The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.

Donor elements and processes for thermal transfer of nanoparticle layers

The invention is related to thermal imageable dielectric layers and thermal transfer donors and receivers comprising dielectric layers. The thermal transfer donors are useful in making electronic devices by thermal transfer of dielectric layers having excellent resistivity, good transfer properties and good adhesion to a variety of receivers.

A fastening device is disclosed for attachment to a pole without the need for tools and without the need for excessive force to mount or remove the device from the pole. The device has an interior channel that is open along a side of the fastening device. The opening in the channel along the side of the device is defined by first edges that are uniformly spaced apart and contiguous second edges that are angled away from each other, starting with the spacing of the first edges, until their spacing is equal to the diameter of the pole. To mount the fastening device to the pole its top edge with the widest spacing of the second edges are placed against the pole and pushed on to the pole for a short distance before rotating the bottom of the fastening device on to the pole. This attachment sequence distributes the mounting force timewise making it easier to attach or remove the fastening device to or from the pole.
