    摘要: In the manufacture of an electronic device comprising thin-film circuitry, a semiconductor film (1) on a polymer substrate (2) is subjected to a laser treatment, for example laser crystallisation, with a laser beam (10). The beam is reflected by the film (1). Significant non-uniformities in the laser treatment are found to occur due to a local overheating effect if the reflected laser beam (10b) impinges again on the heated area of the film (1). Thus, the invention identifies a particularly acute problem which arises when the device substrate (2) is of a heat-distortable polymer material in that the substrate (2) may experience temporarily a concave distortion at an area where the semiconductor film (1) on the substrate (2) is heated by the incident laser beam (10). The beam is focused as well as reflected by the concave distorsion in the substrate (2). Although the film (1) is under a window (22) of the treatment cell (20), this focused and reflected laser beam (10a) is prevented from being reflected again onto the same area of the film (1), by tilting the window (22) and/or the film/substrate (1, 2) at the area of the concave distortion at an angle theta so as to be inclined with respect to one another along the path of the beam (10).

    摘要: PCT No. PCT/JP83/00441 Sec. 371 Date Aug. 17, 1984 Sec. 102(e) Date Aug. 17, 1984 PCT Filed Dec. 17, 1983 PCT Pub. No. WO84/02296 PCT Pub. Date Jun. 21, 1984.This invention relates to improvement in a laser machining apparatus using both a working laser generator (101) and an auxiliary energy supplying apparatus (110) such as a plasma or the like. A feature of the invention is that an auxiliary energy generated from the auxiliary energy supplying apparatus is radiated on a workpiece (118) to a location which is slightly apart from an irradiation point of a working laser beam. In a preferred embodiment, the auxiliary energy supplying apparatus (110) is attached to a rotary disk (113) thereby allowing the auxiliary energy to be radiated to a location which is always preceding an irradiation point of the laser beam in the working progressing direction. The auxiliary energy may be radiated onto a surface opposite to the surface of a workpiece to which the laser beam is radiated. With such an arrangement, working efficiency and accuracy are improved and a structure of the whole system is also simplified, resulting in less failure. To further improve the working efficiency, in a desirable embodiment, an abrasive grain may be supplied to the working portion, or a high-pressure working fluid may be jetted thereto, or a working fluid to which an ultrasonic vibrational energy was applied may be supplied thereto. Further, a focal point automatic adjusting mechanism of the laser beam may be provided.

    摘要: The invention relates to a method for laser cutting a meltable material, comprising heating and melting at least a part of the meltable material at a laser cutting spot (44) by using a laser beam (34) directed towards the laser cutting spot (44), and removing at least a part of the meltable material molten by the laser beam (34) by using an assist fluid jet (44), which is at least partially directed towards the laser cutting spot. The assist fluid jet (52) comprises liquefied carbon dioxide and the assist fluid jet (52) is provided at the laser cutting spot (44) at least partially in a liquid phase and at a higher pressure than an ambient pressure at the laser cutting spot (44). The invention further relates to an apparatus (30) for laser cutting and the use of liquefied carbon dioxide as an assist fluid (48) for laser cutting.

    摘要: A method and apparatus particularly for additively manufacturing materials that are susceptible to hot cracking. The additive manufacturing process may include a leading energy beam (16) for liquefying a raw material to form a melt pool (20), and a trailing energy beam (17) directed toward a trailing region of the melt pool. The trailing energy beam may be configured to enhance agitation and/or redistribution of liquid in the melt pool to prevent hot cracking, reduce porosity, or improve other characteristics of the solidified part. The method and apparatus also may improve processing parameters, such as adjusting vacuum level to prevent volatilization of alloying agents, or providing a chill plate to control interpass temperature. The process may be used to form new articles, and also may be used to enhance tailorability and flexibility in design or repair of pre-existing articles, among other considerations.
