  • Patent number: 8436456
    Abstract: A wiring board (10) of the present invention includes: a through hole (11b), provided in a semiconductor chip mounted region (15), penetrating the wiring board (10); and a groove pattern (13), provided on a solder resist (9) formed on the semiconductor chip mounted region (15), leading to the through hole (11b). The foregoing configuration makes it possible to guide, via the groove pattern (13) to the through hole (11b), moisture that collects in the semiconductor chip mounted region (15) and therefore to effectively discharge the moisture from the semiconductor chip mounted region (15). Thus, a semiconductor device (30) that employs the wiring board (10) does not suffer from vaporization and expansion, inside of it, due to heat that is applied at the time of manufacturing the semiconductor device (30) and at the time of mounting the semiconductor device (30) on a mount substrate. It is therefore possible to reduce expansion of the semiconductor device.

  • Patent number: 8431942
    Abstract: A rounded square lens is used instead of a hemispherical lens in an LED package to produce a substantially Lambertian light emission pattern. A cross-sectional view of the rounded square lens cut along its diagonal forms a semicircular surface so as to emulate a hemispherical lens in areas close to the diagonal. A cross-sectional view of the lens cut along its width bisecting the lens forms a bullet shaped surface narrower than the semicircular surface but having the same height as the semicircular surface. The four corners of the lens are rounded. The surface of the lens smoothly transitions between the two surface shapes. Since the rounded square lens has a diagonal dimension larger than a maximum allowable diameter of a hemispherical lens in the same package body, a larger LED die may be used with the rounded square lens to output more light without increasing the size of the package while maintaining a Lambertian emission.
