摘要:
A semiconductor laser device including a laser element stack array emitting a two-dimensional array shaped group of laser beams consisting of rows of laser beams arranged linearly in parallel in a broken line configuration and optical elements arranged in front of the array, receiving rows of laser beams bent and collimated in a direction substantially perpendicular to the orientation of the broken line configuration. Laser beams are emitted from emitters or groups of emitters and are rotated by right angles so as to convert the laser beams to a plurality of rows aligned in parallel in an approximate ladder rung configuration and the distance between center axes of the rows of laser beams is shortened to condense the laser beams by converting them to a group of laser beams emitted from a common object and thereby making all laser beams converge to a single image.

A semiconductor laser apparatus according to an exemplary embodiment of the present invention is provided. For example, the apparatus may include a single or a plurality of stacked-array laser diodes, first beam compressors, and a separating optical device separating the group of laser beams into subgroups of laser beams in a first direction, and deflecting the subgroups of laser beams so that the subgroups of laser beams approach in the first direction and recede from one another in a second direction. In addition, a collimating optical device may be provided which is adapted to deflect the subgroups of laser beams in the first and second directions by the same angles. Further, a beam converter may be included which divides each subgroup of laser beams and turning the axis thereof, and second beam compressors and a group of cylindrical lenses can be provided that can make the angle of divergence in the first direction close to the angle of divergence in the second direction.

A sticking method for sticking a support plate onto a substrate in such a way that the support plate can be removed in quickly and easily is provided. The sticking method according to the present invention includes the step of sticking a support plate 3 onto a wafer 2 via a first adhesive layer 4 provided on the wafer 2, a separate film 5 provided on the first adhesive layer 4, and a second adhesive layer 6, provided on the separation film layer 5, which either is higher in rate of dissolution in a solution than the first adhesive layer 4 or dissolves in a solvent different from the solvent in which the first adhesive layer 4 dissolves.
摘要:
An adhesive composition of the present invention includes a polymer as a main component. The polymer is produced by copolymerization of a monomer composition which includes chain-structured alkyl (meth)acrylate and a monomer containing a maleimide group. This makes it possible to provide an adhesive composition used for forming an adhesive layer in which adhesive strength is kept in a high temperature environment. That is, it becomes possible to provide an adhesive composition that allows forming an adhesive layer which has high adhesive strength in a high temperature environment (particularly at 200° C. to 250° C.).
