Processing device for forming pattern on surface of material by using diffraction of laser beam, and method thereof
A processing device to form a pattern on a surface of an object to be processed using diffraction of a laser beam emitted from a laser source, the device including: a main body providing a space to process the object using the laser beam emitted from the laser source; a laser transmission unit formed at a first portion of the main body, and configured to diffract the laser beam so that a diffracted laser beam is emitted toward the object; an actuator formed at a second portion of the main body, and connected to the laser transmission unit so as to change an emission pattern of the diffracted laser beam while rotating the laser transmission unit vertically/horizontally or in a set radius; and a controller provided at a third portion of the main body, and connected to the actuator to control an operation of the actuator.

Laser Printing of Solder Pastes
A method for fabrication includes providing a donor sheet, including a donor substrate, which is transparent in a specified spectral range, a sacrificial layer, which absorbs optical radiation within the specified spectral range and is disposed over the donor substrate, and a donor film, which includes a paste and is disposed over the sacrificial layer. The donor sheet is positioned so that the donor film is in proximity to a target location on an acceptor substrate. A pulsed laser beam impinges on the sacrificial layer with a pulse energy and spot size selected so as to ablate the sacrificial layer, thus causing a viscoelastic jet of the paste to be ejected from the donor film and to deposit, at the target location on the acceptor substrate, a dot having a diameter less than the spot size of the laser beam.

Analysis apparatus and analysis method
According to one embodiment, an analysis apparatus includes a stage on which to place a sample, a light source, a film thickness measurement unit, and a controller. The light source generates a laser beam to irradiate the sample with the laser beam to cause vaporization of the sample. The film thickness measurer measures a thickness of the sample at a first position where the laser beam irradiates the sample. The controller controls at least one irradiation condition of the laser beam based on the measured thickness of the sample.

COMPONENT WITH STRUCTURED PANEL(S) AND METHODS FOR FORMING THE COMPONENT
A manufacturing method is provided during which a plurality of first apertures are formed in a first plate to provide an apertured first plate. A plurality of second apertures are formed in a second plate to provide an apertured second plate. The apertured first plate and the apertured second plate are bonded to a base sheet to form a structure. The base sheet is bent to form a bend in the structure between the apertured first plate and the apertured second plate.
