Light emitting device using led
InactiveUS20040190304A1Extended service lifeEffective coolingDischarge tube luminescnet screensLighting heating/cooling arrangementsLength waveLight emitting device
A light-emitting device (10) using an LED is proposed. This light-emitting device (10) is provided with a packaging substrate (1), a light-emitting element (2) which is mounted on this packaging substrate (1) with its face down, a fluorescent member (3) that is arranged face to face with a light-extracting surface (S) of the light-emitting element (2) without contacting the light-emitting element (2) and an optical member (4) which receives light that has been emitted from the light-emitting element (2) and made incident thereon through the fluorescent member (3), and aligns the incident light toward the outside of the device. Light, emitted from the light-emitting element (2), is made incident on the fluorescent member (3) to excite the fluorescent material so that the fluorescent material re-emits light having a wavelength different from that of the incident light. Those light rays, emitted from the light-emitting element (2), which have not been absorbed by the fluorescent member (3) and have passed through the fluorescent member (3) and those light rays that have been emitted from the fluorescent material are made incident on the optical member (4) and are aligned. Because the fluorescent member (3) is not made in contact with the light-emitting element (2), it does not receive the heat from the light-emitting element (2) through heat conduction, and consequently becomes less susceptible to degradation due to heat. Moreover, with the face-down mounting structure, the fluorescent member (3) and the optical member (4) can be placed closer to the light-emitting element (2) as long as they dose not contact the light-emitting element (2). Consequently, the service life of the fluorescent material or the fluorescent-material-mixed resin that tends to deteriorate can be lengthened, lights can be extracted more efficiently, and light rays can be properly aligned in a predetermined direction.

Optical interference apparatus
InactiveUS20070195330A1Easy to calculateEasily and accuratelyRadiation pyrometryDiagnostics using lightBeam splitterLight beam
A light emission section includes light generators which are operated on the basis of drive signals from a controller so as to emit near infrared interferable light beams having different specific wavelengths to a light interference section. The light interference section includes a beam splitter having a low-reflection region. The beam splitter allows a most portion of the near infrared interferable light beams to propagate toward an object to be examined, and reflects a portion of the near infrared interferable light beams to a movable mirror. The beam splitter causes interference between measurement light reflected by the object and reference light reflected by the movable mirror, and the resultant interference light propagates to a light detection section. The light detection section receives the interference light and calculates predetermined information regarding the object by making use of the quantity distribution of the interference light. A display section displays the calculated information.

Wet-recess (develop) gap-fill and bottom anti-reflective coatings based on a polyamic acid or polyester platform are provided. The polyamic acid platform allows imidization to form a polyimide when supplied with thermal energy. The gap-fill and bottom anti-reflective coatings are soluble in standard aqueous developers, and are useful for patterning via holes and trenches on semiconductor substrates in a dual damascene patterning scheme. In one embodiment, compositions composed of polyamic acids can be used as gap-filling (via-filling) materials having no anti-reflective function in a copper dual damascene process to improve iso-dense fill bias across different via arrays. In another embodiment, the same composition can be used for anti-reflective purposes, wherein the photoresist can be directly coated over the recessed surface, while it also acts as a fill material to planarize via holes on the substrate. The compositions described here are particularly suitable for use at exposure wavelengths of less than about 370 nm.
