    摘要: A technology capable of improving receiver sensitivity and improving insulation withstand voltage in an ultrasonic transducer is provided. An ultrasonic transducer comprises: a lower electrode; an insulator covering the lower electrode; a cavity portion disposed on the insulator so as to overlap with the lower electrode; and an upper electrode disposed so as to overlap with the cavity portion. In this ultrasonic transducer, an insulator is inserted between the upper and lower electrodes in a part not having the cavity portion. By this means, sum total of thickness of insulators between the upper and lower electrodes in a part not having the cavity portion is larger than sum total of thickness of insulators between the upper and lower electrodes in a part having the cavity portion.

    摘要: The performance of a sensor in a semiconductor device can be improved. A plurality of oscillators forming an ultrasonic sensor are arranged on a main surface of a semiconductor chip. A negative-type photosensitive insulating film which protects the oscillators is deposited on an uppermost layer of the semiconductor chip. At the time of exposure for forming an opening in the photosensitive insulating film, the semiconductor chip is divided into a plurality of exposure areas and exposed, and then, the exposure areas are jointed so that the entire area is exposed. At this time, a stitching exposure area is arranged so that a center of the stitching exposure area in a width direction in the joint portion of the adjacent exposure areas is positioned at a center of a line which connects centers of oscillators located above and below the stitching exposure area.

    摘要: A method for improving productivity when manufacturing a semiconductor device. A lower electrode, insulating films, an upper electrode and insulating films are formed on a semiconductor substrate in a sensor region. A cavity is formed between the insulator films above the lower electrode. The lower electrode, insulating film, the cavity and insulating film, and an upper electrode form a variable capacity sensor. The cavity is formed by etching a sacrificial pattern between the insulation films by way of a hole formed in a pair of insulation films. Other than in the above sensor region, a dummy lower electrode and four insulating films are formed on the TEG region on the semiconductor substrate; and a dummy cavity is formed between a pair of insulation films above the lower electrode however no conductive layer on the same layer as the upper electrode is formed on the dummy cavity.

    摘要: Disclosed herein is a latchable MEMS switch device capable of retaining its ON or OFF state even after the external power source is turned off. It is unnecessary not only to introduce novel materials such as magnetic material but also to form complicated structures. At least one of the cantilever and pull-down electrode of a cold switch is connected to a second MEMS switch. A capacitor between the cantilever and pull-down electrode of the cold switch is charged by the second MEMS switch. Thereafter since the cold switch is isolated in the device, the charge remains stored. Therefore, the cold switch can remain in the ON state since the charge continues to create electrostatic attraction between the cantilever and the pull-down electrode.

    摘要: To provide a method for manufacturing a semiconductor device, by which it is possible to form a trench or a hole with high aspect ratio on a methylsiloxane type film with low dielectric constant with causing neither via-connection failure nor short-circuit failure even when lower level interconnect is covered with etching stopper. The method comprises the processes of forming a layered film with a silicon oxide film on upper layer of a methylsiloxane type film and forming the layered film using a hard mask. When the etching stopper is etched, the silicon oxide film acts as a hard mask for the methylsiloxane type film, and transfer of faceting to the methylsiloxane type film is prevented. Thus, parasitic capacitance of multi-level interconnect can be reduced without causing via-connection failure and short failure.
