Title: Light emitting diode array
Inventor: KOMATSU HIROSHI
IPC: H01L27/15
Filed: 1988-04-08
Abstract: PURPOSE:To simplify the process and to reduce the inter-element pitch by forming light-emitting diodes composed of a compound semiconductor thin film formed on the surface of a silicon single crystalline substrate and a monolithically formed integrated circuit(IC) for driving the LEDs. CONSTITUTION:A light-emitting diode(LED) 103 is formed on a P-type single- crystal silicon substrate 101 by sequentially growing epitaxially a silicon integrated circuit (IC) region 102 and an n-type GaAs buffer layer, an n-type AlGaAs layer, a P-type AlGaAs layer, and a P-type GaAs contact layer thereon. The LEDs and ICs receive power or a signal from contact pads formed on the single- crystal silicon substrate 101. Accordingly, the wire bonding must be applied only to wiring of a couple of contact pads for Vss terminals, etc., per chip. This reduces the number of bonding wires, thereby contributing to shortening the pitch between the LEDs. This further contributes to simplifying the process and reducing the picture element pitch to allow a high resolution LED printer head to be obtained.

Abstract: PURPOSE:To obtain a bipolar transistor BPT with a gate for large power by forming the gate region in stripe state and intersecting an emitter layer perpendicularly  with the gate region to increase the width of the emitter layer regardless of the interval between the gate regions. CONSTITUTION:Striped emitter layers 3a are arranged perpendicularly with gate regions 4, and a base electrode 6a is provided on a base layer 2 between the emitter electrodes 5a and the emitter layers 3a perpendicularly with the gate regions.

Filed: 1995-04-13
Abstract: PURPOSE: To cancel the other reflected component by one reflected component at a terminator and to enhance the accuracy of the analysis by utilizing that only one polarity is inverted while the reflected wave from the terminator due to the error in the terminator condition of an analyzing area holds the proportional relation between the electric field and the magnetic field of an incident wave. CONSTITUTION: A space circuit network method and a TLM method define the voltage and the current corresponding to an electric field and a magnetic field at the same node and time of an area to be analyzed, generate a reflected wave when there is a discontinuous part at the time of propagating the electromagnetic wave, and advances reversely to the input. That is, the polarity of either the electric field or the magnetic field becomes reverse to the input wave, and the impedances of the input wave and the reflected wave are the same media, and hence they become the same value. This phenomenon is satisfied for the reflected wave due to an error under incomplete terminator condition.  Accordingly, the same terminator conditions are independently applied to the electric field and the magnetic field, and the other reflected wave is cancelled by the one reflected component by utilizing that the one is inverted while the proportional relationship between the electric field and the magnetic field of the input wave.
