Abstract

A plug electrode is subject to etch back to remain in a contact hole and expose a barrier metal on a top surface of an interlayer insulating film. The barrier metal is subject to etch back, exposing the top surface of the interlayer insulating film. Remaining element structures are formed. After lifetime is controlled by irradiation of helium or an electron beam, hydrogen annealing is performed. During the hydrogen annealing, the barrier metal is not present on the interlayer insulating film covering a gate electrode, enabling hydrogen atoms to reach a mesa part, whereby lattice defects generated in the mesa part by the irradiation of helium or an electron beam are recovered, recovering the gate threshold voltage. Thus, predetermined characteristics of a semiconductor device having a structure where a plug electrode is provided in a contact hole, via barrier metal are easily and stably obtained when lifetime control is performed.

Abstract

In a target detection apparatus, an extraction unit extracts reflection points that are located within a subjected-to-determination region and stationary as subjected-to-determination points. A connection-sequence generation unit generates a connection sequence by extracting the subjected-to-determination points that are sequentially connected to each other at intervals of less than or equal to an allowable connection distance from one of the subjected-to-determination points as a starting point. In response to a determination condition being met, a determination unit determines that the vehicle is traveling in a specific environment where accuracy of the target information is decreased. The determination condition includes a condition that a determination score set according to a number of the subjected-to-determination points belonging to the connection sequence generated by the connection-sequence generation unit exceeds a score threshold.

Abstract

An ignition device for an internal combustion engine includes a switching circuit and a control circuit. The control circuit monitors a voltage level inputted to a switching device which is installed in the switching circuit and connected to a primary winding of an ignition coil. The control circuit includes an overvoltage protection circuit which outputs an energization inhibit signal to inhibit energization of the switching device when the monitored voltage level is higher than an overvoltage threshold level. When the monitored voltage level exceeds the overvoltage threshold level in an output duration in which the energization control signal is outputted, the overvoltage protection circuit stops output of the energization inhibit signal until the output duration expires. This enables the switching device to be protected from damage and an ignition operation to be executed at a correct timing to eliminate a risk of damage to the internal combustion engine.

Abstract

An in-vehicle sensor device has an active sensor, an odometry sensor and a processing part. The processing part calculates estimated detection values of a stationary object by using position information parameters, a mounting angle of the active sensor, and a detection error of the odometry sensor. The position information parameters specify a relative position relationship between the stationary object and the active sensor.

Abstract

A ranging apparatus is provided which is mountable to a vehicle and emits a transmit wave and receives a reflected wave arising from reflection of the transmit signal from an object to calculate a distance to the object. The ranging apparatus includes a light transmissive window, a heater, and a controller. The light transmissive window permits at least one of the transmit wave and the reflected wave to pass through. The heater works to add thermal energy to the light transmissive window. The controller uses an ambient temperature outside the ranging apparatus and a speed of the vehicle derived from a vehicle speed sensor to control energization of the heater. When the vehicle speed sensor is malfunctioning, the controller controls the energization of the heater as a function of the ambient temperature without use of the speed of the vehicle.
