Abstract:
Apparatus for permitting the laser transfer of organic material from a donor onto a substrate to form a layer of organic material on one or more OLED devices, wherein the donor includes a laser light-absorbing layer, and a layer with heat transferable organic material.
Abstract:
A method of laser forward transfer is disclosed. Photo energy is directed through a photon-transparent support and absorbed by an interlayer coated thereon. The energized interlayer causes the transfer of specific regions of a heterogeneous tissue sample coated thereon across a gap and onto a receiving substrate or into a receiving vessel.
Abstract:
A method for creating a microarray of biomaterial uses a laser (14), a receiving substrate (18), and a target substrate (17). The target substrate (17) comprises a laser-transparent support (15) having a laser-facing surface (30), a support surface (32) and a composite material (16) that has a back surface (34) in contact with the support surface (32). The composite material (16) comprises a matrix material and a biomaterial to be deposited. The target substrate (17) is positioned such that the laser (14) is directed through the laser-facing surface (30) and through the laser-transparent support (15) to strike the composite material (16). The laser (14) has sufficient energy to desorb the composite material (16), causing it to be lifted from the support surface (32). The receiving substrate (18) is positioned such that the lifted composite material is deposited on it at defined locations. The steps are repeated such that the composite material (16) is deposited in a microarray of deposited composite material (26).

The method includes the step of providing a wafer including at least one of prefabricated circuitry, a bottom electrode and at least one organic layer (52). The method further includes the step of providing a first substrate having a first color specific organic light emitting layer (61) formed thereon. The method also includes the step of selectively applying electromagnetic radiation to the first substrate to transfer portions of the color specific light emitting layer onto to the wafer to form at least one first color specific subpixel.
Abstract:
The aim of the invention is to produce two or three dimensional local intercalation zones with clearly defined boundaries, using purely physical processes. According to the invention, atomic, molecular or ionic guest substances are injected directly into the host substance. The atoms, molecules or ions must then possess a sufficiently high level of kinetic energy to induce atomic defects in the surface of the host substance, the guest substances then diffusing into said defects. The atomic concentration of the intercalated guest substances and the vertical expansion of the intercalation zone can be controlled in order to achieve a specific result by predetermining the kinetic energy of the guest substances striking the host substance and the bombardment times.
Abstract:
A method of creating a localized deposition on a sample in a vacuum chamber (320) having an ion source (300) generating a positively-charged beam of ions (350) and a separate source of primary radiation (360) generating a beam of radiation. An ion beam (350) from the ion source (300) is directed toward the sample (330), and the primary radiation beam is applied to the sample to generate emitted electrons (370) from the sample (330). The ion beam (350) and the primary radiation beam (360) are positioned so that the paths of at least some of the ions in the ion beam (350) and the paths of at least some of the emitted electrons (370) from the sample (330) substantially overlap in space near the sample (330) surface. The energy of the ions in the ion beam (350) and the electric potential of the sample (330) are adjusted to substantially prevent deposition of ions on the sample (330). Further, the energy of the ions in the ion beam (350) and the electric potential of the sample (330) are adjusted so that a portion of the ions in the ion beam (350) are neutralized by the emitted electrons (370) from the sample (330), and such neutralized ions continue in their respective paths to deposit (380) on the sample (330).
