    摘要: A VCSEL includes a first distributed Bragg reflector (DBR) of a first conductivity type formed on a substrate and including at least one semiconductor layer to be oxidized, an active region having a column shaped structure and formed on the first DBR, and a second DBR of a second conductivity type. At least one hole starting from a surface of the first DBR and reaching the at least one semiconductor layer to be oxidized is formed in the first DBR outside of a column shaped structure of the second DBR. An oxidized region is formed in the semiconductor layer to be oxidized by selectively oxidizing from a side surface of the hole. In the first DBR, a first current path is formed by a conductive region surrounded by the oxidized region, and a second current path is formed by a conductive region not surrounded by the oxidized region.

    摘要: It is an object to provide an epitaxial silicon wafer that is provided with an excellent gettering ability in which a polysilicon layer is formed on the rear face side of a silicon crystal substrate into which phosphorus (P) and germanium (Ge) have been doped. A silicon epitaxial layer is grown by a CVD method on the surface of a silicon crystal substrate into which phosphorus and germanium have been doped at a high concentration. After that, a PBS forming step for growing a polysilicon layer is executed on the rear face side of a silicon crystal substrate. By the above steps, the number of LPDs (caused by an SF) that occur on the surface of the epitaxial silicon wafer due to the SF can be greatly reduced.

    摘要: Disposed is a jet mill that has a cylindrical pulverization chamber (10) and a classification chamber (6) that connects to the pulverization chamber (10). A fine-powder discharge port (4a) and a classification rotor (7) are provided in the classification chamber (6). A feedstock supply port (5) and at least one gas emission nozzle (11) are provided in the pulverization chamber (10). The shape of the classification chamber (6) is a cone that starts on the inner wall of the pulverization chamber (10), and is angled towards the classification rotor (7). This configuration gives the jet mill high efficiency of pulverization and reduces the amount of powders left in the chamber when the jet mill has finished running.

    摘要: An optical waveguide includes a first waveguide region and a second waveguide region. The first waveguide region includes a first core, a first clad provided around the first core, and a light reflecting surface. The light reflecting surface has at least one function of (i) reflecting light from a longitudinal direction of the first core toward a direction crossing the longitudinal direction and (ii) reflecting light from the crossing direction toward the longitudinal direction of the first core. The second waveguide region continues from the first waveguide region. The second waveguide region that includes a second core, and a second clad provided around the second core. The second core of the second waveguide region is thinner than the first core of the first waveguide region. A total thickness of the second core and the second clad is smaller than that of the first core and the first clad.

The reflective mirrors include a pair of a high refractive index layer and a low refractive index layer. The impurity concentration of the second reflective mirror is higher than that of the third reflective mirror. The band gap energy of the high refractive index layer in the second reflective mirror is greater than the energy of the wavelength of a resonator formed of the first reflective mirror, the active region, the current confining layer, the second reflective mirror, and the third reflective mirror.
