A first transistor required for decreasing leak current and a second transistor required for compatibility of high speed operation and low power consumption can be formed over an identical substrate and sufficient performance can be provided to the two types of the transistors respectively. Decrease in the leak current is required for the first transistor. Less power consumption and high speed operation are required for the second transistor. The upper surface of a portion of a substrate in which the second diffusion layer is formed is lower than the upper surface of a portion of the substrate where the first diffusion layer is formed.

Disclosed is an optical semiconductor device which can be improved in light shift precision and restrained from undergoing a loss in light transmission. In this device, an inner side-surface of a first optical coupling portion of an optical coupling region and an inner side-surface of a second optical coupling portion of the region are increased in line edge roughness. This manner makes light coupling ease from a first to second optical waveguide. By contrast, the following are decreased in line edge roughness: an outer side-surface of the first optical coupling portion of the optical coupling region; an outer side-surface of the second optical coupling portion of the region; two opposed side-surfaces of a portion of the first optical waveguide, the portion being any portion other than the region; and two opposed side-surfaces of a portion of the second optical waveguide, the portion being any portion other than the region.

A semiconductor device is provided with an insulating layer formed on a base substrate, an optical waveguide composed of a semiconductor layer formed on the insulating layer, and an insulating film formed along an upper surface of the insulating layer and a front surface of the optical waveguide. A peripheral edge portion of a lower surface of the optical waveguide is separated from the insulating layer, and the insulating film is buried between the peripheral edge portion and the insulating layer.

A rectangular optical waveguide, an optical phase shifter and an optical modulator each formed of a semiconductor layer are formed on an insulating film constituting an SOI wafer, and then a rear insulating film formed on a rear surface of the SOI wafer is removed. Moreover, a plurality of trenches each having a first depth from an upper surface of the insulating film are formed at a position not overlapping with the rectangular optical waveguide, the optical phase shifter and the optical modulator when seen in a plan view in the insulating film. As a result, since an electric charge can be easily released from the SOI wafer even when the SOI wafer is later mounted on the electrostatic chuck included in the semiconductor manufacturing apparatus, the electric charge is less likely to be accumulated on the rear surface of the SOI wafer.

An object is to prevent a short failure in magnetic tunnel junction and thereby suppress a semiconductor device having a magnetic memory cell from having deteriorated reliability. First, a data reference layer and a cap layer are patterned. After formation of an oxygen-free first insulating film on their side walls, a base layer, a data recording layer, and a tunnel barrier layer are patterned. During patterning of the base layer, data recording layer, and tunnel barrier layer, adhesion of a metal substance of the data reference layer and the cap layer to the side wall of the tunnel barrier layer can be prevented because the data reference layer and the cap layer are covered by the first insulating film.

In a method of manufacturing a semiconductor device, a first semiconductor portion and a second semiconductor portion made of silicon are formed on a base body via an insulation layer, and a third semiconductor portion including a semiconductor layer made of germanium is formed on the second semiconductor portion. Next, an insulation film is formed above the first semiconductor portion, an opening portion reaching the first semiconductor portion from an upper surface of the insulation film is formed, and a metal silicide layer is formed on a part of an upper surface of the first semiconductor portion exposed to the opening portion.

A technique is provided which can prevent the quality of an electrical signal from degrading in an optical semiconductor device. In a cross-section perpendicular to an extending direction of an electrical signal transmission line, the electrical signal transmission line is surrounded by a shielding portion including a first noise cut wiring, second plugs, a first layer wiring, first plugs, a shielding semiconductor layer, first plugs, a first layer wiring, second plugs, and a second noise cut wiring, and the shielding portion is fixed to a reference potential. Thereby, the shielding portion blocks noise due to effects of a magnetic field or an electric field from the semiconductor substrate, which affects the electrical signal transmission line.

Windings of each phase in a three-phase AC motor are independent of one another. A motor control unit gives, to windings of each phase (U, V and W-phase), currents (IU, IV, IW) obtained by adding, to a fundamental sine wave current, a current having a frequency which is three times as high as that of the fundamental sine wave current. That is,&#xb7;sin &#x3c9;&#xb7;sin 3&#x3c9;&#xb7;sin(&#x3c9;+2/3&#x3c0;)+&#xb7;sin 3&#x3c9;&#xb7;sin(&#x3c9;+4/3&#x3c0;)+&#xb7;sin 3&#x3c9;Also, amplitude Ia of a current having a frequency which is three times as high as that of the fundamental sine wave current is set to a predetermined value smaller than amplitude I of the fundamental sine wave current.

A foam-type hair dye apparatus, has a container main body in which liquid hair dye containing a dye, surfactant, and thickener is stored; at least one jetting orifice for jetting the liquid hair dye from the container main body; and a liquid reservoir member disposed opposite the jetting orifice. The jet flow of liquid hair dye from the jetting orifice is blended with air from outside the container and transformed into foam-type hair dye in the liquid reservoir member. A foam-type hair dye discharge apparatus according to another embodiment uses a double aerosol container including an inner bag filled with undiluted solution; an outer container disposed on the external side of the inner bag and filled with compressed gas in the space between the outer container and the inner bag; and a valve mechanism.

It is assumed that an element to be detected,in a position sensor is mounted on a rotary shaft with the center O&prime; of the element to be detected eccentric from a center of rotation O by a distance d. When the rotary shaft is rotated at a fixed speed, the positions at angles 0&deg; and 180&deg; are accurately detected by a sensor,, while the positions at angles 90&deg; and 270&deg;, the sensor detects the positions P,&prime; and P,&prime;, instead of P,and P,which are originally to be detected, resulting in undulation of detected positions as shown in FIG. 3(,). The peak value of the unduration and an angle of rotation at which the peak value is found are determined. An amount of eccentricity d is found from the peak value, a detection error with respect to the command position (angle) is found from the amount of eccentricity d and the angle at which the peak value is found, and correction the by detection error is made with respect to the command position, providing a corrected command position to a motor.

Position control device

A servo controller capable of controlling motors to be driven in different control modes, such as a synchronous motor and an induction motor, irrespectively of the type of the motor, and also capable of carrying out servo control by using incremental feedback signals. A control section common to individual motors and a control section dedicated to each motor are provided in a servo controller. The common control section is always used, while the dedicated control section is selectively used in accordance with the motor to be driven. Thereby, motors each requiring a different control mode can be controlled by the servo controller of one type. The use of th servo controller of one type can reduce maintenance management and a load on a CNC. Also, the provision of the control section common to individual motors can restrain increases of size, installation area and manufacturing cost of the device.
