Abstract: PURPOSE:To realize the direct formation of a solder bump without providing a substrate metal by a method wherein ultrasonic waves are applied in such a way that an electrode part is brought into contact with molten solder containing dispersed solid particles so that the molten solder containing dispersed solid particles is attached selectively to the electrode by means of alloying. CONSTITUTION:After one face of a double-faced adhesive tape for hightemperature use has been attached to the reverse side of a silicon wafer 11, this assembly is attached to a glass sheet via the other face of the adhesive tape. The assembly is then dipped into spouting molten solder 23 by keeping it in a vertical position, and an ultrasonic vibrator 25 is inserted into the molten solder at a location near the silicon wafer 11 so that ultrasonic waves can be applied. As the type of solder, Pb-Sn eutectic solder which contains dispersed solid particles is to be used.

Abstract: PURPOSE:To improve the efficiency of plotting by instructing the extension start point and a point in the extensive direction of a leader line, computing an angle in the extensive direction based on those instruction points, and finding a prescribed correction angle from a computed result. CONSTITUTION:The plotting of the leader line is performed by instructing a position (2) in the extensive direction and a position (3) in a character write direction and executing them sequentially after instructing the extension start point (1) by an operator. A computer computes the angles with a horizontal line of the leader lines (1)-(2) based on the coordinate data of instructed points (1) and (2). Thereby, the angle can be corrected to a prescribed angle blocked in advance at a prescribed interval near to a computed value. For example, the angle is corrected to 45 deg. when a computed angle shows a range between 37.5 deg. and 52.5 deg.. Thence, the leader line A is decided. Character write lines (2)-(3) are corrected either in a horizontal direction, a vertical direction, or the extending direction of the extensive direction based on the direction of the leader line A.
