Abstract: PURPOSE:To enlarge the area of contact of a bump electrode with a pad and thereby to lower a contact resistance and to enable attainment of high-density packaging by a method wherein the pad in contact with the bump electrode and the surface of the ground of the pad are shaped in indentation. CONSTITUTION:In a region wherein a bump electrode 7 is formed, a silicon nitride film is made to remain in the shape of a lattice in a region under an opening part of a pad 1, and a field oxide film 4 is made to grow. Then a plurality of field oxide films 4 grow at some distance from each other in the region under the opening part of the pad 1, and an indented shape is formed as the shape of a section. When an interlayer insulation film 5 is made to grow and stick on the films and the pad 1 constructed of a wiring metal layer of Al or the like is formed subsequently, their surfaces are indented in accordance with the shape of the ground. Next, a surface protection film 2 is made to grow and stick thereon, the central part of the pad 1 is opened, a barrier metal layer 6 of which the central part has an indented shape is laminated so that it covers the exposed opening part of the pad 1 and the surface protection film 2 around the opening part, and the bump electrode 7 is formed thereon. According to this method, the area of contact of the pad 1 with the barrier metal layer 6 and the bump electrode 7 is enlarged and attainment of high-density packaging is enabled.

Title: Checking method for heater wire consisting of semiconductive layer
Inventor: MURATA YOSHIKAZU
IPC: G01R31/50
Filed: 1981-03-18
Abstract: PURPOSE:To measure the characteristic without requiring a large electric charging equipment, by putting a heater wire in a thermostat and measuring the conduction current value at a temperature slightly higher than the temperature where the resistance value is changed rapidly and measuring the insulation resistance at a temperature slightly lower than this temperature. CONSTITUTION:A drum or a bundle of heater wires is put in a thermostat as it is, and heater wires are charged electrically after the temperature of them is raised to a temperature slightly higher than a temperature TO where the insulation resistance is changed rapidly, and thus, the capacity of the electric charging equipment is reduced because the conduction current is small, and the characteristic of heater wires is confirmed sufficiently on a basis of the conduction current value. Meanwhile, the insulation resistance is measured at a temperature slightly lower than the temperature TO by a megger. In this case, though a measured value rho1 is affected by the conductor resistance of conductors connected to a heater because the measured value rho1 is very small, it is sufficient if it is detected that the measured value rho1 is smaller enough than a value rho2. By this method, a long-sized heater wire is checked within a range of practicality without a large-capacity electric charging equipment.
