Title: Manufacture of semiconductor device
Inventor: ISHIKAWA KATSUYA
IPC: H01L21/31
Filed: 1989-09-28
Abstract: PURPOSE:To form a buried oxide film of high quality (less leakage current) by forming a buried oxide film by the thermal oxidation method. CONSTITUTION:After a silicon substrate 1 is patterned with a resist mask 2, silicon ions are implanted at a vertical angle to the substrate to form an amorphous layer 3 in a region where a desired buried oxide film is to be formed. Next using an oxide film mask 4, a small pit is opened above the amorphous region by the dry etching method. After a nitride film 5 is deposited, only the film at the pit bottom is removed by dry etching, and only the amorphous film by wet etching. And, a heat treatment is made in an oxidizing atmosphere to form a buried oxide film 6 in the part free of amorphous layer. Finally, a silicon pit is filled with polysilicon 7 and the oxide film mask 4 is removed by the wet etching method.

IPC: H02J1/00
Filed: 1987-10-07
Abstract: PURPOSE:To attain a stable operation for an electronic circuit by separating a power conversion storage section a power consumption electronic circuit when an output voltage of a power conversion storage section does not reach a threshold level. CONSTITUTION:When a voltage required for the operation of a power consumption electronic circuit 2 is not kept by a power conversion storage section 3 due to the deficiency of power supply, the circuit 2 is disconnected to boost a voltage across a capacitor 5. In disconnecting the power consumption electronic circuit 2, the input resistance is increased and since a constant current flows through the increased resistance, the voltage applied to the power conversion part is increased, resulting that the voltage across the capacitor 5 is boosted to a voltage such that the power consumption circuit 2 is operated normally for the purpose. Thus, in supplying a signal with power to the power consumption electronic circuit 2 of the local area network from the center, the power consumption electronic circuit 2 is operated stably in the normal state.

Filed: 1989-09-29
Abstract: PURPOSE:To hold down a ground bounce by controlling the channel of a transistor in ON-resistance by a method wherein the gate of an output transistor is kept adequate in potential by control. CONSTITUTION:Potential generating means 3 and 4 generate a prescribed potential which ranges from an L logic state to an H logic state during a prescribed time between the logic state transition point of input signals and a prescribed point, where the logic transition point is detected through delay circuits 6 and 6', and a potential correspondent to the logic state of the input signals after the transition point when the prescribed time has elapsed. Output transistors TP1 and TN interposed between a prescribed power source line and a load are driven by the generated potential of the potential generating means 3 and 4. As mentioned above, the gate potentials of the output transistors TP1 and TN are kept by control at prescribed value between the L and the H logic state during the prescribed time between the transition point of the input signal and a prescribed point. By this setup, the channel of a transistor can be controlled in On-resistance and a ground bounce can be restrained.

IPC: G01S7/52
Filed: 1987-10-08
Abstract: PURPOSE:To reduce the influence of a background noise greatly and to improve detecting ability and azimuth determination accuracy by taking a narrow-band frequency analysis. CONSTITUTION:A couple of right and left reception directional beams are generated and a received signal through the right and left beams is processed by Fourier transformation to obtain a right and a left beam complex spectrum by the narrow-band frequency analysis. Components of equal frequency of those right and left complex spectra are complex-added and the absolute value of the amplitude of the composite addition complex spectrum is obtained. The respective frequency elements of the absolute-value spectrum are amplified by anatomic gain controller (AGC). Then a maximum value is detected in the spectrum after the AGC amplification and complex spectra of the same frequency element with the maximum spectrum having the maximum value are selected from the complex spectrum received through the right and left beams to obtain the vector angle difference between the right and left beam complex spectra. Then a target azimuth is calculated from the vector angle difference.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To accurately detect a radio wave reflector provided on the surface of a road as a driving guide with a simple constitution. SOLUTION: The displacement (x) of an automobile 33 from a lane marker 31 composed of a radio wave reflector which is installed to the surface 32 of a road for guiding the traveling route of an automobile 33 can be calculated from the phase difference between received signals due to the difference between the distance R1 to the marker 31 from the reception antenna 36 of the automobile 33 and the distance R2 to the marker 31 from the transmission-reception antenna 35 of the automobile 33, with the interval between the antennas 36 and 35 being maintained (d), when the height (h) is fixed. Only an unmodulated radio wave can be transmitted form the antenna 35. When another reception antenna is added, the height (h) can be calculated together with the displacement (x), because two kinds of phase differences can be measured.
