An abrasion-proof and static-erasing coating is formed on the contact surface of a contact image sensor. The coating comprises a first film having a high hardness and a low conductivity, a second film formed on the first film and having a low hardness and a high conductivity, and a third film having a high hardness and a high resistivity providing an abrasion-proof insulating external surface.

The present invention relates to a semiconductor device and, more particularly, has for its object to provide a technique for improving the performance of a semiconductor device having a ground terminal and a plurality of signal terminals arranged around the ground terminal. To attain the object, the present invention features isolation between a ground terminal (5, 35) connected to a functional block (11) and a ground terminal (6, 36) connected to a functional block (12). Thus, a ground potential applied to one of the functional blocks through the corresponding ground terminal is prevented from varying depending on the magnitude of a current flowing through the other functional block. This improves the performance of each functional block to improve the performance of the semiconductor device.

In an apparatus for fabricating a carbon coating, an object such as a magnetic r cording medium is disposed on a side of an electrode connected to a high-frequency power supply. Ultrasonic vibrations are supplied to the object. Discharge is generated between the electrode connected to the high-frequency power supply and a grounded electrode to fabricate a carbon coating on the surface of the object. Also, an electrode interval is set to 6 mm or less, pressure between the electrodes is set to 15 Torr to 100 Torr, whereby high-density plasma is generated to form an ion sheath on an anode side. Therefore, a coating is fabricated on the surface of the object by bombardment of ions.

A method of wiring a head suspension assembly includes fixing a tube binding a plurality of wires on a suspension assembly, and fixing the wires extending from the fixed tube on the suspension while leading them to a top side of the suspension. The suspension has a tab frame with first and second frames. Each wire led to the top side of the suspension is bonded to the second frame of a tab frame. An insulation film is removed from each connecting portion of the wires to connect the wires to respective connecting pads of the slider. A first frame is bent substantially perpendicular to the suspension, and the second frame is bent substantially perpendicular to the first frame, thereby positioning the wires bonded to the second frame at the connecting pads on the slider. The wires are then ultrasonically welded to the respective connecting pads on the slider.

A head gimbal assembly is provided with a slider that flies above the surface of a disk, and a head for reading/writing data from/onto the surface of the disk. One or more conductive wires are connected to the head and are used to transmit data. A load beam supports the wire(s) thereon and holds the head/slider near a front end of the load beam. Each wire forms a wire loop between the head connecting point edge and the wire fixing point. A predetermined portion of each wire loop is pressed from above on the surface of the load beam, and then pushed toward the head connecting point edge, thereby plastically deforming a section between the head connecting point edge and the predetermined portion of the wire loop.

A method for fabricating a semiconductor device including a semiconductor layer structure, a source electrode and, a drain electrode formed on the semiconductor layer structure, and a source interconnection connected to the source electrode is provided. The method includes the steps of: (a) forming the semiconductor layer structure on a substrate; (b) forming a metal layer structure so as to cover the semiconductor layer structure; (c) forming a resist layer having a predetermined pattern on the metal layer structure: (d) performing a first etching process for the metal layer structure using the resist layer as a mask so as to form the source electrode, the drain electrode and the source interconnection; and (e) performing a second etching process for the semiconductor layer structure using the resist layer as a mask so as to form a transistor gap portion between the source electrode and the drain electrode. The respective first and second etching processes in the steps (d) and (e) are performed using the same resist layer as the mask in the same chamber.

When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.
