Title: Manufacture of semiconductive device
Inventor: KANEDA HIROSHI
IPC: H01L21/321
Filed: 1989-04-14
Abstract: PURPOSE:To make possible the reliable and firm connection between a bump and a lead frame by a method wherein a semi-spherical contact part is provided on the point of a terminal, such as the lead frame and the like, in such a way as to correspond to the central recessed part of the upper surface of the bump. CONSTITUTION:A bump 2 having a recessed part in its upper surface is formed at a part, to which an electrode is connected, of a substrate 1 and a part, to which a terminal 3 to be electrically connected with the bump 2 is connected, of the bump 2 is formed into a semi-spherical recessed part. Moreover, a protruding part of the terminal 3 is made to abut on the recessed part of the bump 2 and the bump 2 and the terminal 3 are connected to each other. As the connection between the bump and the terminal is the connection between a part having a semispherical protruding form and a part having a semi-spherical recessed form, a surface contact over a wide area becomes possible and at the same time, an auto-line effect between the contact point of the bump 2 and the contact point of a lead frame or the like is also added. Thereby, a bonding can be executed easily, rapidly and reliably.

Abstract: PURPOSE: To prevent treatment irregularity and to enhance the coating efficiency of a treatment soln. while stabilizing electrostatic coating treatment by providing an intermediate tank having an excessive treatment soln. receiving pan and a solenoid valve under an atomizer and a discharge tank having the same structure as the intermediate tank. CONSTITUTION: A treatment soln. becomes a fine mist 13 by upper and lower atomizers 2a, 2b and 70-90% of the mist is bonded to a charged steel strip 1 but the greater part of the remainder thereof falls to the rear surface of the steel strip 1 as an ineffective part under gravity. A liquid receiving pan 5 is present under the lower atomizer 2b and the accumulated soln. is gathered in an intermediate tank 8 along the inclination of the pan. When the soln. gathered in the intermediate tank 8 becomes a definite amt, a solenoid valve 20a is opened to send the soln. to a discharge tank 11 and, when the discharge of the ineffective treatment soln. in the intermediate tank 8 is completed, the solenoid valve 20a is closed to cut off the electric conduction by the treatment solns. in the discharge tank 11 and the intermediate tank 8.  By this constitution, the electric leak caused by the ineffective treatment soln. is eliminated and the generation of treatment irregularity caused by the non-charge of the mist 13 is also prevented.

IPC: G11B21/21
Filed: 1984-05-16
Abstract: PURPOSE:To prevent a floating head slider from slanting breadthwise and perform high-density recording by setting the slider breadthwise position of a load force point on the slider slightly off the breadthwise center line of the slider toward the outer peripheral side of a disk. CONSTITUTION:The load force point position (w) on the slider 13 is usually on the breadthwise center line of the slider, but shifted slightly in this invention from the breadthwise center line of the slider toward the outer periphery side of the disk by DELTAy.
