    摘要: [Object] To provide a bismuth-substituted rare-earth iron garnet crystal film (RIG) which has an insertion loss of less than 0.6 dB and which can be produced in a high yield, as well as an optical isolator.[Solving means] Provided is a bismuth-substituted rare-earth iron garnet crystal film which is grown by liquid phase epitaxy on a non-magnetic garnet substrate represented by a chemical formula of Gd3(ScGa)5O12, wherein the RIG is represented by a chemical formula of Nd3-x-yGdxBiyFe5O12, and x and y satisfy 0.89×1.43 and 0.85≦y≦1.19. In contrast to conventional RIGs, the RIG represented by the chemical formula of Nd3-x-yGdxBiyFe5O12 of the present invention has an insertion loss of less than 0.6 dB and makes it possible to reduce the amount of heat generated because of absorption of light at wavelengths of about 1 μm. Hence, the RIG has such a remarkable effect that the RIG can be used as a Faraday rotator used for an optical isolator in a high-power laser device for processing.

    摘要: P type semiconductor well regions 8 and 9 for device separation are provided in an upper and lower two layer structure in conformity with the position of a high sensitivity type photodiode PD, and the first P type semiconductor well region 8 at the upper layer is provided in the state of being closer to the pixel side than an end portion of a LOCOS layer 1A, for limiting a dark current generated at the end portion of the LOCOS layer 1A. In addition, the second P type semiconductor well region 9 at the lower layer is formed in a narrow region receding from the photodiode PD, so that the depletion layer of the photodiode PD is prevented from being obstructed, and the depletion is secured in a sufficiently broad region, whereby enhancement of the sensitivity of the photodiode PD can be achieved.
