    • PURPOSE:To easily form band drum-shaped CCB bumps by a method wherein, after large and small contact holes have been formed in a photoresist, lead and tin are evaporated one after another on the surface, an unnecessary solder- evaporated film is removed and this assembly is wet-backed inside a furnace. CONSTITUTION:An integrated circuit pattern is formed on a wafer 1; after that, a glass protective film 2 is applied to the surface; holes are made in prescribed positions; contact holes 4 are made; after that, thin solder substratum electrodes 5 are evaporated and formed on inner peripheral faces. Then, a photoresist 6 is applied; inverted taper-shaped contact holes 4a, 4b are formed at the upper part of the solder substratum electrodes 5; lead and tin are evaporated on the surface; solder evaporated films 7a whose volume is large and whose tin content is high are applied to the inside of the contact holes 4a having a large diameter; solder evaporated films 7b whose volume is small and whose tin content is low are applied to the inside of the contact holes 4b having a small diameter. Then, these films are melted and united inside a reflow furnace; molten solders whose volume is small are stretched in the upward and downward directions; hand drum shapes are formed. Accordingly, it is possible to easily form hand drum-shaped CCB bumps.

    • PURPOSE:To reduce the connecting resistance of bump electrodes to wirings by so forming a pad larger than an opening on the opening as to connect it through the opening to the wiring, and providing the electrodes on the pad. CONSTITUTION:A pad 16P is connected through a connecting hole 15 to aluminum wirings 13. The upper face of the pad P16 is flattened. The area of the pad 16P is, since there is no restriction in the periphery, much larger than that of the hole 15, and can be formed, for example, 25 times or more as large as it. The pad 16P is covered by the substrate metal film 19 of the electrode 20B. That is, since the pad 16P having an area larger than the opening 15 is formed on the opening 15, the connecting area of the wirings 13 to the film 19 is equivalently increased. Here, when the diameter of the hole 15 is set to 10mum, the connecting resistance of the pad 16P to the wirings 13, i.e., the connecting resistance of the aluminum film to the aluminum film is

    • PURPOSE:To improve the adhesive strength of a metallic film deposited by evaporation on wafers to be treated after sputter etching and to decrease through-hole resistance by constituting a vapor deposition device of three chambers; an etching chamber, evaporating source chamber and vapor deposition chamber. CONSTITUTION:The plural Si wafers are attached to a substrate holder 24 and are first put into the etching chamber 21. The inside of the chamber 21 is evacuated and gaseous Ar is introduced through an inlet 37 into the chamber; thereafter, a high- frequency voltage is impressed between a counter electrode 33 and the holder 24 by an electric power source 31 and the surface of the wafers 25 are etched by Ar ions. The gas contg. the generated SiO2 particles is discharged through a discharge port 38 and thereafter the holder 24 is introduced into the vapor deposition chamber 26 by opening a gate valve 39. The metallic vapor from the evaporating source 22 in the lower evaporating source chamber 23 is then deposited by evaporation on the wafer surfaces by opening the gate valve 56 in the lower part of the chamber 26. Impurities such as SiO2 do not stick on the vapor deposited surfaces of the wafers and therefore the film deposited by evaporation is deposited with the high adhesive strength by evaporation on the wafer surfaces.

    • PURPOSE:To enable to electrically and favorably connect the base metal film of the bump electrode with the wirings for connection even though the bump electrode is microscopically formed by a method wherein the wirings for connection, which are electrically connected with the base metal film, are formed at a position in the same height as that up to the surface of the wiring substrate or the surface of the insulating film for semiconductor chip protection. CONSTITUTION:First wiring films 4, first interlayer insulating films 5 and second wiring films 6 are formed on a wiring substrate 1 and second interlayer insulating films 7 are formed on the second wiring films 6. Moreover, wiring films 8 for connection and a third aluminum wiring film are formed on the second interlayer insulating films 7 and metal films 10 for isolation are formed on the wiring films 8 and the third aluminum wiring film 9. Then, masks 13 are formed using a photolithography technique, an etching is performed on the metal films 10 for isolation, and furthermore, an etching is performed on the aluminum film for third-layer wiring to form the wirings 8 for connection and the third wiring 9. After that, the masks 13 are removed using a release agent, an insulating film 11 for semiconductor chip protection is coated, the shoulder parts of the wirings 8 for connection are made to expose by performing a soft etching and an etching is performed on tantalum films 14 and 15. Lastly, a solder bump base metal film 12 and a bump electrode 2 are formed. As the diameter of the bump electrode 2 can be made smaller without forming any hole in the insulating film 11 for protection, a higher integration can be contrived.
