    摘要: To prevent a point defect and a line defect in forming a light-emitting device, thereby improving the yield. A light-emitting element and a driver circuit of the light-emitting element, which are provided over different substrates, are electrically connected. That is, a light-emitting element and a driver circuit of the light-emitting element are formed over different substrates first, and then electrically connected. By providing a light-emitting element and a driver circuit of the light-emitting element over different substrates, the step of forming the light-emitting element and the step of forming the driver circuit of the light-emitting element can be performed separately. Therefore, degrees of freedom of each step can be increased, and the process can be flexibly changed. Further, steps (irregularities) on the surface for forming the light-emitting element can be reduced than in the conventional technique.

    摘要: A semiconductor light emitting device including a p-type electrode structure and having a low contact resistance and high reflectance is provided. The semiconductor light emitting device comprises a transparent substrate, an electron injection layer having first and second regions on the transparent substrate, an active region formed on the first region, a hole injection layer on the active layer, a first electrode structure on the second region, and a second electrode structure on the hole injection layer, and comprises a first layer including nitrogen and a second layer including Pd. The low contact resistance and high reflectance can be obtained by forming a trivalent compound layer composed of Pa—Ga—N at an interface between the hole injection layer, which is composed of p-GaN, and the metal layer of the p-type electrode.

    摘要: Semiconductor switches, such as thyristors, may be light activated by introducing the light into the switch via a groove having a sloped surface to receive the triggering light. The use of a sloped surface increases the surface path length between points of different electrical potential in the groove and, therefore, reduces the likelihood of electrical breakdown on the groove wall. In one particular embodiment, a light-activated thyristor includes a semiconductor anode layer, an n-base layer, a p-base layer and a semiconductor cathode layer disposed parallel to a thyristor plane. A thyristor axis lies perpendicular to the thyristor plane. A groove having a light refracting side wall extends into the thyristor from the anode layer. A portion of the light refracting side wall is disposed non-parallel to the thyristor plane and to the thyristor axis, and extends in the n-drift layer.

    摘要: A semiconductor light emitting device is formed by adhering a semiconductor layered portion having a light emitting layer forming portion to a conductive substrate via a metal layer. The metal layer has at least a first metal layer for ohmic contact with the semiconductor layered portion, a second metal layer made of Ag, and a third metal layer made of a metal which allows adhesion to the conductive substrate at a low temperature. As a result, the rate of reflection of light from the metal layer increases due to the presence of Ag in the metal layer. Further, the metal in the metal layer is prohibited from diffusing into the semiconductor layer, so that the semiconductor layer does not absorb light. And therefore the brightness of the semiconductor light emitting device can further be increased.

The light emitting device has the light emitting layer portion composed of a compound semiconductor and has a double heterostructure in which a first-conductivity-type cladding layer, an active layer and a second-conductivity-type cladding layer are stacked in this order; and the light emitting layer portion is applied with emission drive voltage through an oxide transparent electrode layer formed so as to cover the main surface of the second-conductivity-type cladding layer. A bonding pad composed of a metal is disposed on the oxide transparent electrode layer, and to the bonding pad an electrode wire for current supply is bonded. Between the second-conductivity cladding layer and the oxide transparent electrode layer, a cushion layer composed of a compound semiconductor having a dopant concentration lower than that of the second-conductivity-type cladding layer is disposed.
