Abstract: PROBLEM TO BE SOLVED: To obtain a metal wiring structure which increases the parasitic capacitance, by which the diffusion of Cu is suppressed with good efficiency and with increases the reliability of an element, by a method wherein a part of an insulating film adjacent to a conductive line is changed into a denatured layer by increasing a density or by implanting impurities. SOLUTION: A trench 12 is formed on a semiconductor substrate on which an insulating film such as a silicon oxide film 11 or the like is formed, and a gas such as BH3 , PH3 , SiH4 , Si2 H6 or the like is injected into the silicon oxide film 11 together with a carrier gas. As a result, the density of the silicon oxide film 11 is increased, a part of the silicon oxide film 11 is changed into a substance which prevents the diffusion of Cu, and a denatured layer 13 is formed. Then, a conductive substance layer 14 is formed and etched back to form a conductive line. In this manner, since an element such as P, Si, N or the like is injected in a process to form metallic interconnection, Cu atoms or ions which are diffused from a Cu film are changed into a compound such as Cu3 P, Cu3 Si or an axide, and the diffusion of the Cu is suppressed.  Consequently, the reliability of an element can be increased.

Abstract: PURPOSE:To facilitate a data processing and to enable an image conversion processing such as the enlargement/reduction and work of images without restoring information by encoding the binary data of images with a run length in the unit of a byte. CONSTITUTION:An image converting means calculates the run length by successively extracting the binary data from a pixel string for one line. When the run is the first run of the line and the black run, the run length of white run is turned to '0' and the '0' of one byte is written so as to arrange the picture elements from the biginning of the line in the order of white run and black run. Next, it is discriminated whether the run length exceeds a length 255 for expressing it with one byte or not, when the run length exceeds it, '255' is written and the '0' of one byte is continuously written. Then, the '255' is subtracted from the run length, it is discriminated again whether the run length exceeds the value or not and when the run length does not exceed it, the run length is written. When there is the next run, it is extracted and similarly processed, when processing for one line is completed, the '0' of two bytes is written as a line end code, and the encoding processing is performed to all the lines.
