Abstract: PURPOSE:To form bump electrodes of high density which only requires a simple technique and a low manufacturing cost by supplying solder collectively to a wide region including a plurality of terminal electrode parts that are formed at openings of a protective film and are quite densely in existence or to the whole surface of a substrate. CONSTITUTION:A protective film 16 is formed at the whole surface of terminal electrode parts 15 that are input/output terminals of a semiconductor integrated circuit and protective film opening 18 are formed on the protective film 16 by photoetching and then, the terminal electrode parts 15 are exposed. Then bump electrode materials are formed on the protective film 16 including the terminal electrode parts 15 and the bump electrode materials 19 are dissolved by treating with heat and then, bump electrodes 20 are formed at the terminal electrode parts 15. The bump electrodes are thus manufactured efficiently with a simple technique and a process is performed at a low cost. Moreover, as the bump electrodes of high density are formed, elements which are disposed with a number of terminals and the terminal electrode parts of high density are packaged.

Title: Production of magnetic recording medium
Inventor: MORITA HIROSHI
IPC: G11B5/851
Filed: 1985-04-09
Abstract: PURPOSE:To obtain a protective layer having excellent adhesion and hardness by raising the temp. of a substrate. CONSTITUTION:When the temp. of a substrate in the heating stage is designated as T1, the substrate temp. in forming a ferromagnetic metallic film as T2 and the substrate temp. in forming a protective film as T3, the heating temps. in each stage are regulated to T1>=T2 T2. When T2S>T3, the adhesion of the protective layer is weakened and the adhesion is strengthened as T3 approches T2. Conversely, when T3>T2, distortion is generated between the protective film and the previously formed magnetic film and the peeling rate is increased. Accordingly, T2 and T3 are raised to a temp. as high as possible as long as the magnetic characteristic can be maintained and the temp. difference between both film is advantageously eliminated.
