    摘要: A method for dicing a wafer including first and second layers is provided. A front surface of the first layer contacts a backside surface of the second layer. The method includes: forming a sealing film on the second layer; cutting the first layer from a backside surface along with a cutting line to form a notch; removing the sealing film; irradiating a laser beam on the front surface of the second layer along with the cutting line to form a reforming region in the second layer by a multi photon absorption effect; and dividing the wafer along with the cutting line from the reforming region as a starting point of dividing.

    摘要: A semiconductor wafer has two faces, one of which is a laser light incident face. A dicing sheet is attached to the other face of the wafer, so that it is stretched to thereby apply tensile stress to a laser-reformed region and cause cutting with the reformed region taken as a starting point for cutting. A protection layer, such as light scattering projections and depressions, a light scattering member or a light reflecting member, is provided between the wafer and the dicing sheet to scatter or reflect the laser light passing through the wafer. Thus, the dicing sheet can be protected from being damaged because the laser light converging point is not formed in the dicing sheet.

    摘要: A laser beam is applied to an interior of a wafer through a top surface to form modified areas in a plurality of layers of modified area groups. Intervals of the modified areas in one of the layers of modified area groups differ from intervals of the modified areas in another one of the layers of the modified area groups, which is closer to the top surface of the wafer in comparison to the one of the layers of the modified area groups.

    摘要: A fuming or smoke-emitting device used on a model steam locomotive of railway model driven by an electric motor. It is therefore required to reduce the fuming device as much as possible and to simulate the smoke exhausted from the actual locomotive in the smoking state. This fuming device comprises a container which has therein Nichrome wire and is provided at its upper portion with perforation for exhausting the fume or smoke. The container is filled with water and oil having non-affinity with each other. When the heater is heated, the water is boiled to thereby stir the oil. Thus, the oil is burnt, and the smoke of fume thus produced is exhausted by the steam. The fuming state by this combustion phenomenon simulated the smoke exhausted from the actual locomotive, because this fume thus exhausted from the locomotive is similar in principle to the utilization of the steam exhausted usually from the normal cylinder.

    摘要: A laser processing apparatus has one laser light source that simultaneously radiates laser beams with two wavelengths. Depth positions of focusing points for laser beams are gradually changed in a wafer. Three sets of modifying region groups, i.e., six layers of modifying region groups, are successively formed. One set of modifying region groups constitutes two layers and is formed at a time. The modifying region groups are separated, adjoined, or overlapped with each other along an estimated cut line of the wafer in a depth direction from a surface thereof.
