摘要： The invention relates to a method for dicing a substrate with a laser apparatus, comprising the steps of delivering a laser beam (15) from said laser apparatus to said substrate to dice said substrate (1) in at least two dies. A first assist gas is supplied at the substrate during a first phase of said dicing method and a second assist gas is supplied at the substrate during a second subsequent phase of said dicing method. The method results in a reduced street-width for dicing of the substrate and consequently costly substrate area is saved. The invention also relates to a laser dicing system, a computer program product for executing the method and a silicon die obtainable by the method.

摘要： A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.
摘要翻译：配置挡板以配置通过喷嘴的流体流动。为了提高用于材料的切割，焊接和热处理的加工设备的质量和精度，自对准喷嘴包括可配置的挡板。该可配置挡板可以是金属网格（例如，屏幕）或其它类型的膜（例如，多孔，可渗透等）。在其最初使用处理装置期间，该可配置的挡板利用能量束（例如激光束或等离子体射流）来定制，以产生最佳的流体流速分布。当可配置挡板因使用而变差时，容易被另一个挡板更换或通过使用原位更换机构。为了确保喷嘴和能量束之间的正确对准，在相邻部件之间使用配合的轮廓表面。也可以使用螺纹表面来帮助实现适当的同轴对准。

摘要： An apparatus and method for selectively removing undesired material from the surface of a substrate provides a flow of inert gas over the undesired material susbtrate surface while irradiating the undesired material with energetic photons. The invention enables removal of undesired material without altering the physical properties of the material underlying or adjacent the removed, undesired material. The invention can be applied to produce changes in surface topography (including nano-structuring and surface planarization).

摘要： The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.

摘要： A method is provided for controlling an additive manufacturing process in which one or more energy beams are used to selectively fuse a powder contained in an additive manufacturing machine having a gas flow therein in order to form a workpiece, in the presence of one or more plumes generated by interaction of the one or more energy beams with the powder, wherein the process is controlled by an electronic controller. The method includes: performing a build process to form a workpiece using a set of initial process parameters; sensing a condition of the finished workpiece; using the electronic controller, comparing the condition of the finished workpiece to a predetermined standard; using the electronic controller, changing one or more of the initial process parameters to define a set of revised process parameters; and performing a subsequent build process using the revised process parameters.
