摘要:
The present disclosure relates to a method of manufacturing a substrate. The method includes: (a) forming through holes by applying an anisotropic etching to a silicon substrate from a first surface of the silicon substrate; (b) forming a first insulating film to cover the first surface of the silicon substrate, surfaces of the silicon substrate exposed from the through holes, and a second surface of the silicon substrate opposite to the first surface; (c) forming an opening in a portion of the first insulating film provided on the second surface, the portion of the first insulating film corresponding to an area in which the through holes are formed; (d) etching the silicon substrate using the first insulating film provided on the second surface as a mask, thereby forming a cavity in the silicon substrate; and (e) removing the first insulating film.

A method of producing a light emitting apparatus including a light emitting element, a light emitting element housing having a recess for housing the light emitting element, and a translucent substrate placed on the light emitting element housing is disclosed. The disclosed method includes a fluorescent-substance-containing resin forming step of forming a fluorescent-substance-containing resin on a first side of the translucent substrate which first side is opposite to a second side of the translucent substrate which second side faces the recess. In the fluorescent-substance-containing resin forming step, luminance and chromaticity of light that is emitted from the light emitting element and then transmitted by the fluorescent-substance-containing resin are measured and a thickness of the fluorescent-substance-containing resin is adjusted based on the measured luminance and chromaticity so that light emitted from the light emitting apparatus attains the specified luminance and chromaticity.

A probe card is disclosed that includes a board having a first surface and a second surface facing away from each other and a through hole formed between the first and second surfaces; and a probe needle having a penetration part and a support part. The penetration part is placed in the through hole without contacting the board and projects from the first and second surfaces of the board. The support part is integrated with a first one of the end portions of the penetration part and connected to one of the first and second surfaces of the board. The support part has a spring characteristic. The penetration part is configured to have a second one of its end portions come into contact with an electrode pad of a semiconductor chip at the time of conducting an electrical test on the semiconductor chip.

A semiconductor device 10 has such a structure that a plurality of through electrodes 30 is formed on a substrate 20 and each of terminals of light emitting devices (LEDs) 40 is electrically connected to each of the through electrodes 30 via a bump 50 on a lower surface side. In the semiconductor device 10, moreover, a partition wall 80 for surrounding a mounting region of each of the light emitting devices 40 is formed on the substrate 20. The partition wall 80 is formed by laminating a metal film (Cu) using a thin film forming method such as a plating method. Furthermore, the partition wall 80 is formed to be opposed close to each of side surfaces of the light emitting devices 40 and is provided to surround each of the light emitting devices 40.

According to a sealed structure 60 constituted by anodically bonding a silicon board 20 and a glass plate 40, an upper opening of a recessed portion 22 is sealed in an airtight state by the glass plate 40 by bonding an upper face of a wall portion 26 to the glass plate 40. A voltage applying pattern 70 is formed to surround a light transmitting region to which an optical conversion element 24 is opposed. Further, the voltage applying pattern 70 functions as a cathode pattern applied with a voltage by being brought into contact with a lower face of the cathode plate 50.
