  • Patent number: 8860544
    Abstract: An integrated inductor includes a winding consisting of an aluminum layer atop a passivation layer, wherein the aluminum layer does not extend into the passivation layer and has a thickness that is not less than about 2.0 micrometers. The passivation layer has a thickness not less than about 0.8 micrometers. By eliminating copper from the integrated inductor and increasing the thickness of the passivation layer, the distance between the bottom surface of the inductor structure and the main surface of the semiconductor substrate is increased, thus the parasitic substrate coupling may be reduced and the Q-factor may be improved. Besides, the increased thickness of the aluminum layer may help improve the Q-factor as well.

  • Publication number: 20140126065
    Abstract: An optical substrate having a structured surface that enhances brightness and reduces moire effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).

  • Publication number: 20140064940
    Abstract: A casing of a turbocharger has a main body and a heat dissipating layer disposed on an outer surface of the main body. When heat inside the main body is conducted to the outer surface of the main body, the heat dissipating layer dissipates the heat quickly. Since the heat does not accumulate in the main body, temperature of the main body is low and the casing does not oxidize under high temperature. Therefore, the casing of the turbocharger has low manufacturing cost and is economical.

  • Patent number: 8367186
    Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces the effects of structural defects on perceived image quality. User perceivable image cosmetic defects caused by manufacturing or handling, can be masked by introducing structural irregularities in the optical substrate, which may be non-facet flat sections or in-kind to the defects. Optical defects caused by non-facet flat sections in the prism structure of the optical substrate (e.g., flat-bottom valleys with a certain valley bottom thickness above the base layer, and/or flat-top peaks, and/or openings in the optical substrates that expose flat sections of underlying base layer) can be masked by providing distributed in-kind non-facet flat sections (e.g., flat-bottom valleys, and/or flat-top peaks, and/or openings exposing sections of underlying base layer), to diffuse the prominence of the original defects with the introduced irregularities.

  • Patent number: 8193819
    Abstract: A method and apparatus for improving yield ratio of testing are disclosed. The method includes the following steps. First of all, devices are tested and electromagnetic interference is measured. Next, the test results are examined for whether the devices pass the test or not. Then, electromagnetic interference data are examined for whether the electromagnetic interference data are over a predetermined standard if the devices fail the test. The above-mentioned steps are performed again if the electromagnetic interference data are over a predetermined standard. The test is terminated if the devices still fail the test and the values of electromagnetic interference are still over a predetermined standard.
