Inventor: ARAI HIDETOSHI
IPC: H01L31/04
Filed: 1985-10-31
Abstract: PURPOSE:To improve the packaging efficiency of a solar cell element, by electrically connecting cover glass having a conductive coating with another, on the rear face of the solar cell element.

Title: Vertical insulating gate semiconductor device
Inventor: MURAKAMI NORIO
IPC: H01L29/08
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To relieve a high electric field from a drain and to enlarge voltage limit that can be used by forming the impurity diffusion layer area of a second conduction type, which is at the lower end of a gate electrode and is isolated from a first impurity diffusion layer area. SOLUTION: Since an electric field between an N-type semiconductor substrate 101 and a P-type well diffusion layer 103 becomes weak by a P-type impurity diffusion layer 102 installed near the corner part of the P-type well diffusion layer 103, the high breakdown voltage of a transistor become possible. Then, the depth of the P-type well diffusion layer 103 can be shallowed and therefore the gate length of a VDMOS transistor can be shortened. Since a P well diffusion layer depth and the extension of a P well depletion layer, which are parameters deciding the thickness of a semiconductor substrate 101, are reduced by making the junction of the P-type well diffusion layer 103 to be shallow, the thickness of the substrate 1 can be thinned much more. Then, on-resistance can be reduced while a high withstand voltage characteristic is maintained as it is.  Then, the ability of an element can be made high.

Title: Optical waveguide device with incidence coupler
Inventor: NAKAYAMA YOSHINOBU
IPC: G02B6/122
Filed: 1988-09-30
Abstract: PURPOSE:To eliminate variation in coupling efficiency due to wavelength variation and to enable a small-sized light source to be used by setting wavelength variation in the angle of diffraction of light to the optical waveguide layer of a grating coupler in the same direction with wavelength variation in the angle of total reflection when the waveguide conditions of the optical waveguide layer are satisfied. CONSTITUTION:The optical weveguide layer 12 with a refractive index nf is formed on a substrate with as refractive index ns (nf>ns) and the grating coupler 13 is formed at a part of its surface. Then the wavelength variation in the incident angle of the light to the optical waveguide layer 12 of the grating coupler 13 is set in the same direction with the wavelength variation in the angle of the optical waveguide layer 12 under waveguide conditions. Consequently, even if incident light varies in wavelength, the coupling efficiency does not vary and, for example, a small-sized semiconductor laser is usable as a light source.

Filed: 1990-09-17
Abstract: PURPOSE:To realize a loopback circuit in which the insertion loss of a main signal system is remarkably reduced by inputting a loopback signal branched by a light demultiplexer to the light multiplexer of an opposite circuit through a light amplifier. CONSTITUTION:The light multiplexer 5 and the light demultiplexer 9 are arranged at the input part and the output part of a light repeater 1 respectively, and a signal branched by the light demultiplexer 9 is inputted to the light multiplexer 6 of the opposite circuit through the light amplifier 13. When the signal is desired to loop back form the light repeater 1 to the light repeater 2 of the opposite circuit, the light amplifier 13 is turned on. By adjusting the amplification degree of the light amplifier 13, the loss of the loopback signal system of the light demultiplexer 9 and the light multiplexer 6 can be compensated, and the loopback signal of a sufficient level can be transmitted to the repeater 2. Thus, since the loss of the loopback signal system can be compensated by the light amplifier 13, the braching ratios of the light demultiplexer 9 and the light multiplexer 6 can be made large, and the insertion loss of the main signal system can be reduced.

Abstract: PURPOSE:To prevent erroneous operation due to a late effect, by forming a silicon single crystal island, in which a PNPN thyristor is formed and which has high impurity concentration with respect to another silicon single crystal island, and forming a junction constituting the PNPN thyristor deeper than the junction of the other element. CONSTITUTION:A first silicon single crystal island 11 is formed so that impurity concentration becomes 3X10<14>atom/cm<3>. A second silicon single crystal island 12 is formed so that impurity concentration becomes 4.5X10<14>atom/cm<3>. Thus a dielectric isolating silicon substrate is formed. A transistor having a junction 13 with a depth of 5mum is formed in the silicon single crystal island 11. An PNPN thyristor is formed by using a deep junction 14 having a depth of 30mum in the silicon single crystal island 12. With respect to the PNPN thyristor formed by the deep junction 14, the transistor constituting a late-effect-error preventing circuit is formed by the shallow junction 13. Therefore, a transition time to a conducting state is short, and the erroneous operation due to the late effect can be prevented.
