Filed: 1989-04-07
Abstract: PURPOSE:To form a shallow active base region without generation of crystal defects by a method wherein the active base region is formed by solid phase diffusion of ion-implanted impurities into an SiO2 layer. CONSTITUTION:An SiO2 layer 102 is formed on a semiconductor substrate 101 while a resist layer 103 is formed on the SiO2 layer 102 and the resist layer 103 on a region to be an active base 109 is removed. Impurities are ion implanted in such conditions that impurities are accumulated on the region to be the active base 109 in the SiO2 layer 102, and by removing the resist layer 103 and performing heat diffusion the impurities are solid-phase-diffused in the semiconductor substrate. That is, ion implantation is performed in such conditions that impurities are accumulated on the region to be the active base region of the SiO2 layer 102 and the impurities are solid-phase diffused in the semiconductor substrate. Thus a shallow base region can be formed without being damaged by crystal defects or the like.

Title: Pulse signal controlling circuit
Inventor: HANEDA HIROSHI
IPC: H03K17/60
Filed: 1982-05-24
Abstract: PURPOSE:To improve the off-characteristics of a switching transistor (TR), by applying an amplified high-frequency pulse to a switching circuit at all times and interrupting or passing this pulse in response to a data signal. CONSTITUTION:The amplified high-frequency pulse signal (e) is inputted to a collector of a TR10 via a diode 14, and a pulse data (c) in opposite phase as the signal (e) and a pulse signal (d) in the same phase are inputted to a base and an emitter of the TR10. When no data exists in the signal (c), the TR10 turns off and an emitter of a TR9 is kept at a positive peak value of the pulse (e). When data exists in the signal (c), the TR10 repeats on/off in response to the polarity in data and an amplified pulse data signal (f) is obtained from the emitter of the TR9. Further, in inputting the emitter signal (d) of the TR10, since the emitter potential is higher than the base potential with the TR10 turned off, the TR10 is turned off independently of the time constant comprising its base resistance and base capacitance, and the off-characteristics are improved.

Title: Duty limiting circuit
Inventor: MORISHITA KEIJI
IPC: H04B1/04
Filed: 1995-04-13
Abstract: PURPOSE: To prevent destruction of a transmitter or the like due to duty abnor mality or the like by providing a bias generation circuit or the like which takes the power supply output passing a current sensor as the input and has the output controlled by a cut-off signal from a reduction voltage detection circuit. CONSTITUTION: A power supply output 12 from a power source 11 is supplied to a bias generation circuit 17 through a current sensor 13, and the bias generation circuit 17 gives a bias 20 to a pulse load in the succeeding stage. Normally, the current sensor 13 doesn't show overcurrent, and a cut-off signal 19 doesn't instruct the bias generation circuit 17 to cut off the bias 20. However, if the average value of the bias current is increased and a current sensor output 14 of the current sensor 13 shows overcurrent, an overcurrent decision circuit 15 decides overcurrent. Then, a power supply output control signal us acts upon the power source 11 so as to reduce the voltage of the power supply output 12.  A reduction voltage detection circuit 18 discriminates the reduction voltage, and the cut-off signal 19 instructs the bias generation circuit 17 to cut off the bias 20, thus protecting the pulse load from thermal destruction.

Abstract: PURPOSE:To adjust the ratio of the resistance length of each resistance layer, and to obtain a desired resistance value by forming a reference resistor for generating reference voltage by a metal or a metallic silicide, resistivity of which mutually differs. CONSTITUTION:Reference resistors R1, R2, R3,...R2n-1 are shaped by an intermediate-resistivity metallic layer 2 selectively applied onto a semiconductor substrate 1 and low-resistivity metallic layers 3 selectively applied onto the metallic layer 2. The layer 2 has the three layer structure of a Ti layer, a TiN layer and a Pt layer, and has comparatively high resistivity. The layers 3 are shaped by Au, and have resistivity lower than the layer 2. Consequently, reference currents IREF pass through the metallic layer 2 in regions in which no metallic layer 3 is formed, and pass through the metallic layers 3 in regions in which the metallic layers 3 are shaped. Accordingly, the ratio of the resistance length of the resistors R1, R2, R3,...R2n-1 is adjusted, thus acquiring a desired resistance value.
