Abstract: PURPOSE:To perform the absorption of negative surge efficiently by forming buried layers of p<+> and n<+> type under an anode and a cathode electrodes of a protective diode respectively so as to be closer to each other than an interval of the electrodes located above these layers. CONSTITUTION:When minus surge is applied to a cathode electrode 2, the surge current flows from an anode electrode 1 toward the cathode electrode 2 through a p<+> type diffusion layer 7, a p<+> type buried layer 8, a semiconductor substrate 9, n<+> type buried layer 6 and n<+> type diffusion layer 5. And n<+> type buried layer 6 is formed so as to be close to the p<+> type buried layer 8 thereby preventing a resistive element of the semiconductor substrate 9 comprising a large specific resistance from interrupting as serial resistances of the protective diode. Thus the semiconductor elements can be protected from breakdown by the surge without reducing the effect of absorbing the surge of the protective diode.

IPC: H01L33/22
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To emit light efficiently to the outside by forming a GaAsP epitaxial layer such that a GaP substrate directs upward, thereby spreading the flow of an current applied over the entire PN junction face. SOLUTION: An N-type GaAs1-x Px (0.45<x<1) epitaxial layer 2 is formed on a GaP substrate 1 and an N-type GaAs1-x Px (0.45<x<1) epitaxial layer 3 is formed thereon. P-type impurities, i.e., Zn, are then diffused to form a P-type GaAs1-x Px (0.45<x<1) epitaxial layer 3 and a PN-junction 4. Subsequently, a roughened surface 5 is formed by lapping and etching, and upper and lower electrodes 6, 7 are formed thereon. Consequently, an current applied spreads entirely over the PN-junction 4. An emitted light spreads efficiently to the GaP substrate 1 side and since the blocking ratio of the upper electrode 6 is decreased, a large quantity of light is outputted.

Then, with the resist 6 as a mask a contact hole 4 is opened by anisotropic dry etching. Thereafter, after the resist 6 is removed, the edge 7 of the film 2 formed by etching is rounded by heat treating to complete the contact 4.

Filed: 1989-08-24
Abstract: PURPOSE:To extremely simplify the circuit constitution for discriminating a pulse interval by setting a time ratio of the pulse interval to 5X2<n>:7X2<n>:9X2<n> ((n) is a natural number) at the time of executing the MFM modulation. CONSTITUTION:A time ratio of three kinds of pulse intervals T1, T2 and T3 of an MFM modulating signal is set so as to come to 5X2<3>:7X2<3>:9X2<3>. When an optical signal is made incident on a photodiode 16 of a fixed terminal 5, a reference clock pulse CK from a clock oscillating circuit 19 is counted between pulses of a light receiving signal SR by a binary counter 20. Its count value comes to a count value corresponding to one of the pulse intervals T1, T2 and T3. The pulse interval of the received MFM signal generates an error with respect to the transmitted pulse interval, but by monitoring only the upper three bits, the pulse interval fluctuation of about 10% even at the smallest is allowable, therefore, a sufficient performance for practical use is obtained.
