Coherent ray beams are applied from two directions to form .Iadd.an .Iaddend.interference fringe through interference of the coherent rays. A diffraction grid is disposed in the optic paths of the ray beams substantially in parallel with the interference fringe. The ray beams reflected .[.and.]. .Iadd.or .Iaddend.transmitted by the grid are converged by a lens system and the intensities of the ray beams are measured to detect the relative position between the interference fringe formed by two coherent ray beams and the diffraction grid, thereby to permit a highly accurate alignment of fine semiconductor element.

摘要： In a step for bonding a color filter to a solid-state color-image sensor chip with an adhesive which is curable not only by light or more particularly ultraviolet-ray irradiation but also by heating, pre-curing or partial curing is effected by irradiating light rays after the color filter and the chip has been pressed against each other and correctly aligned with each other in a bonding device and then the chip with the partially-bonded color filter is removed from the bonding device and complete curing of the adhesive is accomplished by heating. According to one embodiment of the present invention the bonding step is carried out in an atmosphere containing the oxygen so that the adhesive which has been squeezed out from the space between the color filter and the chip may be prevented from being cured and subsequently removed in a simple manner. According to a further embodiment of the present invention, prior to the bonding step, the color filter and chip are covered with protective layers or films so that surface flaws may be avoided. Thus, the color filters can be bonded to the chips with a higher degree of accuracy and a higher degree of adhesive strength and the mass production of solid-state color-image sensors can be much facilitated.

摘要： This invention provides an optical head apparatus in which a grating coupler (8), which is formed on a circular region which has a center on an axis (18) and has a periodical structure with dents and projections in a configuration of concentric circles or spirals around the axis (18), input-couples laser light (7) emitted from a semiconductor laser (5) and turns it into waveguided light (16B) which transmits in a waveguiding layer (15B). The waveguided light (16B) is converted, in a region where the waveguiding layer (15B) and a waveguiding layer (15A) overlap each other, to waveguided light (16A) which transmits in the waveguiding layer (15A). By a grating coupler (9), formed on a ring-shaped area which is located around the axis (18), which has a periodic structure with dents and projections of a configuration of concentric circles or spirals around the axis (18), the waveguided light (16A) is radiated and focused onto points (FA), (FB) and (FC) which are located on the axis (18). Light reflected from a reflecting surface (19) is input-coupled by the grating coupler (9) and is converted to waveguided light (21) which transmits through the waveguiding layer (15A) toward the center. The waveguided light (21) is radiated at the innermost edge of the waveguiding layer (15A) and the amount of radiated light is detected by a light detector (10) to obtained control signal and playback signals.
