A thermal evaporation sources are described. These thermal evaporation sources include a crucible configured to contain a volume of evaporant and a vapor space above the evaporant.

Deposition system and method

A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.

Evaporator, deposition arrangement, deposition apparatus and methods of operation thereof

A depositing arrangement for evaporation of a material is disclosed herein. The depositing arrangement has an alkali metal or alkaline earth metal for deposition of the material on a substrate. The deposition arrangement has a first chamber configured for liquefying the material; a valve being in fluid communication with the first chamber, and being downstream of the first chamber, wherein the valve is configured for control of the flow rate of the liquefied material through the valve. The deposition arrangement has an evaporation zone being in fluid communication with the valve, and being downstream of the valve, wherein the evaporation zone is configured for vaporizing the liquefied material; a heating unit to heat the material to higher temperatures before providing the liquid material in the evaporation zone; and one or more outlets for directing the vaporized material towards the substrate.

Printing apparatus includes a donor supply assembly, which positions a transparent donor substrate having opposing first and second surfaces and a donor film formed on the second surface so that the donor film is in proximity to a target area on an acceptor substrate. An optical assembly directs one or more beams of laser radiation to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate. Means are provided to mitigate or compensate for the variation in reflection of the laser radiation across an area of the donor substrate, so as to equalize a flux of the laser radiation that is absorbed in the donor film across the area of the donor substrate.
