Abstract: PROBLEM TO BE SOLVED: To provide a laser, surface emission laser, or LED which has a low threshold current value and a high efficiency by controlling the size, shape and arrangement of quantum dots and separating the quantum dots from each other by a transparent insulator. SOLUTION: On an n-type clad layer 11 of a thickness of T2 which is mode of a C component, quantum dots 1 mode of an A component are formed in a cylindrical shape of a diameter Dqd and height Tqd in a form of being embedded in a matrix made of a D component by a lithography or etching method with the size, position, and distribution density being controlled. A p-type clad layer 10 mode of a B component is deposited in a thickness of T1 on the quantum dots 1 to form a unit light emission layer.  When two or more layers of such unit light emission layers are laminated, a boundary layer 12 consisting of a carrier generator 6 and an optical guide body 7 is disposed between each two unit layers. 1 to 50 layers of such unit layers are so laminated that the positions of the quantum dots of these layers may be aligned with each other to form a multiple structure, which will become a light emission layer (Figures 1, 2, 3, 4, and 5). The light emission layer is assembled into a light emission device of such a structure shown in Figures 6, 7, and 8.

Title: Power semiconductor module
Inventor: MUTO HIROTAKA
IPC: H01L23/64
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To detect the main current of a power semiconductor module to a high frequency domain with high accuracy by significantly reducing the inductance of a current sensor section, which is provided in a main current circuit and formed by folding a conductor in a parallel plate-like shape, by detecting the main current from the potential difference in the sensor section. SOLUTION: A current sensor section 28 is formed by folding a conductor into a parallel plate-like shape. Namely, the sensor section 28 is composed of plates sections 28a and 28c and a bent section 28b connecting one ends of the plate sections 28a and 28b to each other. In addition, detecting terminals 34 and 35 are respectively formed at the other ends of the plate sections 28a and 28b. When the current passage of the sensor section 28 is folded in the parallel plate-like state in this way, the inductance between the detecting terminals 34 and 35 becomes smaller. Since the detected voltage varies depending upon the resistance between the terminals 34 and 35, an output that has a flat frequency characteristic and is proportional to the main current of a power semiconductor module is obtained between the terminals 34 and 35.  Therefore, the module can be protected accurately with a prescribed current value.
