Title: Off-hook detection device
Inventor: MIURA SHIGEO
IPC: H04Q3/72
Filed: 1985-11-14
Abstract: PURPOSE:To always exactly detect an off-hook in communication by making a current on a telephone set into a constant current by providing a constant current diode, and operating the telephone set exactly regardless of a resistance in the telephone set. CONSTITUTION:When the telephone set is in an on-hook state, DC resistances at terminals T1 and T2 become infinity, and the current is scarcely on a LED, and a secondary side transistor TR is placed in an open state, and a potential at an OUT is kept at a regulated value. Adversely, when the telephone set is in an off-hook state, the DC impedances of the terminals T1 and T2 become low within a certain current range, and a secondary side transistor TR in a photocoupler 9 is placed under a saturated state, and an output at the OUT becomes about zero. At such a case, when the constant current value fitted for the specification of an impression current value for a telephone set 2 and a LED 9a is selected as the constant current value of a constant current diode CRD1, the value of a current IF always becomes the value fitted for the specification. And the failure or the damage of the telephone set and the LED 9a can be certainly prevented and also, they are operated exactly.

Title: Improvement of characteristic of mos semiconductor device
Inventor: IWAI HIROSHI
IPC: H01L21/336
Filed: 1989-09-29
Abstract: PURPOSE:To reduce an interfacial level density increased by injecting hot carriers by a method wherein a forward bias is applied to the drain junction of a MOS transistor having deteriorated characteristics. CONSTITUTION:A silicon substrate 1 is set to OV, a negative voltage, such as -5V, is applied to a source 4 and a drain 5 and the junction between the source 4 and the drain 5 is formed so that it is forward biased. That is, forward currents 6 are respectively made to flow between the substrate 1 and the source 4 and between the substrate 1 and the drain 5. Accordingly, if a device is packaged in such a way as to lead out terminals of the substrate 1, a power terminal and an earth terminal are negatively biased and the substrate 1 is positively biased, a forward bias results in being applied to the source 4 and the drains 5 of almost all transistors. Thereby, an interfacial level density increased by injecting hot carriers can be effectively decreased, in particular the reliability of a MOS semiconductor device using fine elements can be significantly improved.

IPC: H01L29/06
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in a threshold voltage and an increase in an on-resistance which are caused by misalignment of a mask. SOLUTION: A length p of a gate electrode layer in a direction of crossing a groove and in a direction parallel to a face of a first semiconductor layer is set to satisfy p/2-m-x>q. Herein, m denotes a distance between a center C1 of a groove in a direction parallel to a face of the first semiconductor device and a center C2 of the gate electrode layer; q denotes a distance between a center C1 of a groove in a direction parallel to a face of the first semiconductor device and a boundary of a second semiconductor layer of a face of a groove and a third semiconductor area; and x denotes a length of a portion where a gate oxide film is thickened at an end part of the gate electrode layer in a direction parallel to a face of the first semiconductor layer.  Thus, in a boundary (T) of a base layer and a source layer on a face of the groove, it is possible to control the relaxation of the electric field since a film thickness of the gate oxide film is uniform and the portion (gap λ) is thin. Therefore, a threshold voltage does not increase.
