Title: Semiconductor device reinforced in its resistance to radiation
Inventor: KASAMA KUNIHIKO
IPC: H01L29/78
Filed: 1986-04-10
Abstract: PURPOSE:To reduce fixed positive charge accumulated in a gate oxide film and interfacial potential, and to improve a resistance to radiation, by forming a gate electrode in the manner such that a compression stress is applied on the boundary surface of a substrate side in the boundary region of the gate oxide film and an Si substrate. CONSTITUTION:A gate electrode is formed by adjusting its film thickness and forming temperature, etc. in the manner in which compression stress is applied both on the side of a gate oxide film and on the side of an Si substrate in a boundary region of the gate oxide film and the Si substrate. As the result of this, even if ionization radiant rays make an incidence thereon, the accumula tion of positive charge and generation of interfacial potential are suppressed, and resistance to radiation extremely increases. The range of optimum compres sion stress is estimated as 0.5-5X10<7> dyn/cm<2>.

Title: Undershoot preventing circuit
Inventor: KAKIZAKI YUJI
IPC: H03K19/088
Filed: 1988-04-06
Abstract: PURPOSE:To clamp an output terminal to zero V by devising the circuit so that a 2nd transistor(TR) is conductive when an undershoot voltage is applied to the output terminal. CONSTITUTION:With the undershoot voltage applied to the output terminal 1, that is, when a collector voltage of a TR Q2 and an emitter voltage of a TR Q3 go below zero V, since the base-emitter voltage of the TR Q3 is biased to 0.7V or over, the TR Q3 is conductive. Thus, a current is supplied from a power supply 3 to the emitter of the TR Q3 and the base-emitter voltage of the TR Q2 reaches 0.7V. Since the base voltage of the TR Q2 in this case reaches 0.7V, the undershoot voltage is clamped to nearly 0V. In this case, since the output voltage is regulated by the base-emitter voltage of the TR Q3 even if a large current flows to the output terminal, the output voltage is always clamped to nearly zero V.

Abstract: PURPOSE:To prevent the breakdown of a photoelectric converting film, by contacting a metallic electrode provided to an image pickup element which extracts a transparent electrode to the outside with a junction type diode of a different type from an element substrate and them utilizing the breakdown of said junction to shunt the high voltage applied to the electrode toward the substrate. CONSTITUTION:An oxide film 9 for insulation is formed on a semiconductor substrate 1 of the 1st conduction type, and a diffusion layer 16 is formed in the stages to form a source 3 and a drain 4 of an MOS switch 2. Electrodes 17, 6 and 14 are formed on the film 9, and at the same time a photoelectric converting film 7 is vapor deposited at the region of the switch 2 by a sputtering or glow discharge method. In addition, a transparent electrode 8 for application of target voltage is formed to the electrode 14 formed on the film 7 and the layer 16 to drive the film 7 by a sputtering or glow discharge method. In this case, the high voltage generated within a sputtering device is shunted toward the substrate 1 via the electrode 14 and the layer 16 by means of the junction different from the substrate 1 and formed to the lower layer of the electrode 14. Thus the breakdown is avoided for the film 7.
