摘要:
The present invention provides a method for fabricating a semiconductor device which initially performs chemical mechanical polishing with respect to a metal film made of copper formed on a semiconductor substrate to form wires composed of the metal film on the semiconductor substrate and subsequently removes a wire-to-wire bridge occurring during the formation of the wires and remaining on the semiconductor substrate to cause unneeded conduction between the wires adjacent to each other. The removal of the wire-to-wire bridge is performed by oxidizing the wire-to-wire bridge into a copper oxide by using an aqueous hydrogen peroxide and then dissolving the copper oxide by using an oxalic acid. This allows the removal of the wire-to-wire bridge without damaging the main bodies of the wires.

A color type determining device is made up of a difference detecting section, a density distribution determining section, a density distribution correcting section, a color line counter, and a color/monochrome determining section. In the difference detecting section, the color type determining device finds, from read data of an original read by a scanner section, a color density for each pixel. In the density distribution determining section, the color type determining device finds a color density distribution for each line, and, based on the color density distribution for each line, determines whether that line is a color line. In the color line counter, the color type determining device counts the total number of color lines, and in the color/monochrome determining section determines from the total number of color lines whether the original is a color original. When the density distribution determining section does not determine whether a line is a color line, the color type determining device corrects the color density distribution using the density distribution correcting section, and re-determines whether the line is a color line.

There is provided an image discriminating apparatus for discriminating the type of an image accurately. The apparatus compares a maximum value R among absolute values of mutual differential values of three color components of each pixel composing an image, with two predefined threshold values &bgr; and &ggr;, respectively, and counts numbers C1-C3 of the monochrome pixels, medium pixels and color pixels, respectively, on the basis of the comparison result for each line within the image. The apparatus judges each line within the image as a color line when C3+C2×&ohgr;>&thgr;, as a monochrome line when Cl>&ngr;, and judges the image as a color image when a number of color lines in the whole image exceeds a threshold value. The second apparatus compares maximum and minimum values of the absolute values of each pixel with three threshold values to judge whether each pixel is a color, medium, ground or monochrome pixel and increments counter values of color, medium and monochrome pixel counters according to the range of each discriminated pixel. When the number of continuous monochrome pixels exceeds a threshold value within the image, the apparatus corrects the three counters and discriminates the type of the image based on the three counters after the correction.

In a plastic packaged semiconductor device, a chip support formed on the same lead frame as leads is disposed so as to extend over the surface of a semiconductor element, the chip support is bonded and fixed to the surface of a polyimide wafer coat on the semiconductor element by means of an insulating tape, the leads are brought into contact with the polyimide wafer coat on the semiconductor element without being fixed, the leads and the electrodes of the semiconductor element are connected by means of gold wires, and these are packaged by a packaging material. Generation of crack in the sealing material thereby prevented, and the thickness of the plastic packaged semiconductor device is reduced.

The electrode comprises a metal substrate and a coated layer of an active material provided on one or both faces of the substrate. The metal substrate is a metal sheet having a plurality of punched holes. The punched holes have burrs along their peripheries so that the apparent thickness including the burrs is at least twice the original thickness of the metal sheet. The burrs improve the engagement between the metal substrate and the coated layer.
