    Abstract: PURPOSE:To form an organometallic compd. into a metallic film under low-temp. conditions without damaging a substrate by heating an organometallic compd. placed on the substrate in the air to decompose the compd. and then exposing the decomposition product to plasma to remove the org. matter. CONSTITUTION:An organometallic compd. is diluted with a diluent, if necessary, and applied on the substrate. The substrate on the substrate is heated in the air or in an oxygen atmosphere and calcined to decompose the compd. The calcined substrate is exposed to plasma to remove the org. matter produced by decomposition. The calcination and plasma treatment are preferably carried out at 200-400 deg.C. An inert gas contg. about 0.01-10% oxygen is preferably used for the plasma treating atmosphere when a noble metal is used, and a reducing gas such as ammonia is used when a base metal is used. Consequently, the organometallic compd. is formed into a metallic film under low-temp. conditions, and the metallic film is formed without damaging the substrate contg. a low- melting-point material.

    Abstract: PURPOSE:To form a uniform and good-quality plating layer over the entire surface to be plated at the time of locally plating a member to be plated having a flat surface by directing the surface downward in a plating soln. and providing an agitator between the surface and an anode at the bottom of a plating bath to uniformly agitate the soln. CONSTITUTION:A long-sized member 21 to be plated consisting of a ceramic substrate having a thin vapor-deposited film 22 on its surface is placed at the upper opening of a plating bath 11, and both side surfaces are covered with a 'Teflon(R)' mask 23 to leave a narrow surface 24 to be plated. A Cu anode 13 is arranged at the bottom of the bath 11 which is filled with a plating soln., a current is applied between the anode 13 and the film 22, and the exposed surface 24 is electroplated. In this case, the plating soln. is sufficiently agitated by the agitator 14 consisting of a shaft 15 and an impeller 16 and provided between the anode 13 and the surface 24 or by the inert gas bubbles 35 discharged from a tube 33 furnished along the surface 44 to be plated, and a Cu plating layer uniform in thickness is formed on the slender surface 24 or 44.

    Abstract: PURPOSE:To keep a sliding state between the bearing part, and the guide shaft of a holder blade at a good condition, and to improve the reliability of the operation of an optical pickup, by forming a uniform solid-state lubricant thin film on either plane the inner peripheral plane of the bearing part, or the outer peripheral plane of the guide shaft of the holder blade, in a range of thickness of 1-3mum. CONSTITUTION:The bearing part of the holder blade 1 having a lens holding part 1a, and the bearing part, is fitted in the guide shaft 5 provided protrusively at a pickup main body 4 in such a way that it can be moved slidably, and the holder blade is moved reciprocally in the axial direction of the guide shaft by a magnetic circuit 6. In this case, the solid-state lubricant thin film having the thickness in the range of 1-3mum, and also formed uniformly, is formed on either plane the inner peripheral plane of the bearing part, or the outer peripheral plane of the guide shaft of the holder blade. In this way, it is possible to generate a good sliding state between the bearing part, and the guide shaft of the holder blade, and to prevent the malfunction of the optical pickup from generating.

    Abstract: PURPOSE:To form the raised part of a photoresist film only on one side edge, and to form a pattern almost as indicated by the design, by carrying out spin coating in such a manner as placing substrates coated with a material to be etched on positions apart from the center of a rotation axis and fixing them. CONSTITUTION:The rectangular ceramic substrate 21 is coated with the material 22 to be etched made of a metal of a prescribed thickness by vapor deposition or the like, and these two substrates 21 are placed on a rotary table 24 apart from its rotation axis, e.g., by 1/2 of the thickness of the substrate 21 so as to give side edges. Then, they are coated with a photoresist soln. on the whole surface by dropping it and spinning the table 24, and dried by the ordinary drying method to form a photoresist film 26. After prebaking it, it is exposed, posi-baked after development, and the material 22 is etched using the post-baked film 26 as a mask to form a prescribed pattern. The film 26 is stripped to complete a thermosensitive printing head.

    Abstract: PURPOSE:To make it possible to form highly reliable electrodes, which do not cause a short-circuit at the time of thermocompression bonding, by a method wherein a conductive paste is applied on the electrode parts in an area of 1/2 or smaller of the areas of the electrode parts by screen printing and when a screen printing plate is pulled apart, the conductive paste coating the electrode parts is conically formed due to the viscosity of the paste. CONSTITUTION:A screen printing plate 12 with apertures 11 to correspond to electrode parts 2 of an electronic component 10 is adhered closely to an electrode part formation surface of the component 10, a conductive paste layer 13 is applied on the parts 2 in an area of 1/2 or smaller of the areas of the parts 2 by screen printing and when the plate 12 is pulled apart, the paste layer 13 coating the parts 2 is conically formed due to the viscosity of the paste layer 13. Thereby, a short-circuit due to the spread of the paste layer at the time of thermocompression bonding is prevented and a highly reliable connection is obtained.

    Abstract: PURPOSE:To assure the electric contact simultaneously preventing a semiconductor element from damaging by a method wherein the electrode surfaces and non-electrode surfaces are coated with insular conductive pastes almost flush with one another. CONSTITUTION:Electrodes 12 and non-electrode surfaces of a semiconductor element 11 are insularly screen-printed with conductive pastes 19 while the semiconductor element 11 with the conductive pastes 19 aligned with the specified positions on a wiring circuit substrate 13 is pressurized to cure the conductive pastes 19. In other words, the electrodes surfaces and the non-electrode surfaces of the semiconductor element 11 are coated with the insular conductive pastes 19 almost flush with one another so that the pushing pressure in case of pressurizing the semiconductor element 11 on the wiring circuit substrate 13 to be brought into contact with each other may be given evenly to overall element. Through these procedures, the electric contact can be assured while eliminating the local pressurization on the semiconductor element 11 thereby preventing the element 11 from damaging.
