The invention relates to a device for pulsed laser deposition and a substrate with a substrate surface, which device includes: a substrate holder for holding the substrate; a target arranged facing the substrate surface of the substrate; a velocity filter arranged between the substrate and the target; a pulsed laser directed onto the target at a target spot for generating a plasma plume of target material; and a plasma hole plate arranged between the target and the substrate. The plasma hole plate has a plasma passage opening divided in an upstream section and a downstream section by a dividing plane. The target spot coincides with the dividing plane, and the surface area of the upstream section is larger than the surface area of the downstream section.

Device for pulsed laser deposition and a substrate with a substrate surface for reduction of particles on the substrate

The invention relates to a filter for filtering particles from a plasma plume. The filter includes a housing with two pass-through openings arranged in the housing wall and forming a pass-through channel for passing at least part of the plasma plume through the housing, which pass-through channel extends from one side of the housing to an opposite side of the housing, at least one primary blade arranged at a distance from and rotatable around a rotation axis, which rotation axis is parallel and spaced apart from the center line of the pass-through channel, with the path of the at least one primary blade intersecting with the pass-through channel and with the at least one primary blade having a contact surface for contact with the plasma plume, which contact surface is facing in the direction of the rotation direction, and a drain channel connecting to a drain opening arranged in the housing wall. A line extending perpendicular from both the center line of the pass-through channel and a radial line extending from the rotation axis through the center line of the pass-through channel and through the path of the at least one primary blade, extends through the drain opening.

Filter for a plasma plume

The invention relates to a method for pulsed laser deposition including the steps of: providing a target and a substrate facing the target; irradiating a spot on the target with a pulsed laser beam to generate a plasma plume of target material and depositing the plasma plume on the substrate; and smoothing the surface structure of the spot on the target prior to irradiating the spot with a pulsed laser beam.

Method for pulsed laser deposition

The invention relates to a method for depositing a target material onto an organic electrically functional material. The method includes the steps of: providing a substrate with an organic electrically functional material, like an emissive electroluminescent layer; creating a vapor plume of target material by pulsed laser deposition; depositing a first layer of target material on the organic electrically functional material, while maintaining the maximum particle velocity of the deposited particles below a preset value; and depositing a second layer of target material on the first layer of target material, while the maximum particle velocity of the deposited particles is above the preset value. The invention also relates to an intermediate product and to an organic light emitting diode.

Method for depositing a target material onto a organic electrically functional material

The invention relates to a method for depositing a material for a target onto a surface of a sample, which method comprises the steps of: irradiating a surface of the target with a laser or electron beam to generate a plume of target material particles; positioning the sample near the plume, such that the target material particles are deposited onto the surface of the sample; rotating the sample around a rotation axis being perpendicular to the surface of the sample onto which the particles are deposited; moving the laser beam along the surface of the target, such that the plume moves in a radial direction in relation to the rotation axis; pulsing the laser beam at a variable frequency.

Method for depositing a material

The invention relates to a device for projecting an image on a surface, comprising: a light source generating a light beam; a mask arranged in the path of the light beam; a lens arranged behind the mask to focus the image of the mask on a surface, wherein the surface is not parallel to the lens, wherein at substantially each position along the edges of the mask the distance v to the lens and the distance b of the corresponding position at the edges of the image of the mask to the lens correspond substantially to the formula 1/v+1/b=1/f, wherein f is the focal length of the lengths. The invention also relates to a device for moving the image on the surface.
