A method of forming a bump electrode on an IC electrode includes the steps of forming a ball bond on an IC electrode by a wire bonding apparatus, moving a bonding capillary upward, moving the bonding capillary sideways and then downward, bonding an Au wire to the ball bond portion, and cutting the Au wire. The Au wire is prevented from coming in contact with portions around the ball bond portion other than the ball bond portion by presetting a descent position of the bonding capillary to a position higher than a position in which the ball bond is formed.

The component (2) is first brought into point or line contact with the sheet (3) so as to avoid entrapment of air therebetween. The contact area between the component and the sheet is then gradually spread until the entire bottom surface of the component is adhered to the sheet.

By a manufacturing method including a process of supplying a connection-releasable connecting material (4) onto a surface of a plurality of chip parts (3) and a process of connecting the plurality of chip parts (3) by the connecting material (4), there is formed a chip assembly (1) comprised of the plurality of chip parts (3) connected with each other by means of the releasable connecting material (4). Further provided is a method of preparing the chip assembly (1), a process of releasing connection achieved by the connecting material (4) between a target chip part and an adjacent chip part, and a process of mounting the target chip part separated through releasing of the connection onto a board and soldering the same, thereby providing chip parts capable of easily coping with an increase of operation speed of chip parts on the process of mounting line, achieving an improved space efficiency, and suppressing waste of resources.

The top surface of an insulating substrate is formed with a plurality of electrodes for bump connection, while the undersurface of the insulating substrate is formed with external terminals which are arranged in an array. On the insulating substrate is provided a semiconductor chip. The undersurface of the semiconductor chip is formed with bump electrodes. The electrodes for bump connection are electrically connected to the bump electrodes by means of a conductive adhesive. The space between the semiconductor chip and the insulating substrate is filled with a resin which integrates the above two and dissipates heat generated from the semiconductor chip.

A method for bonding leads of an IC component with electrodes of a circuit board includes the steps of using a mounting device to hold the IC component with flat portions of the leads inclined downward, mounting the IC component on the circuit board at a predetermined position thereof with the IC component held by the mounting device, moving the mounting device toward the circuit board to compress the IC component against the circuit board at the predetermined position while allowing the leads to flex to accommodate for nonuniformity in the heights of metal pieces to be bonded with the electrodes and bending of the circuit board. In this manner, the flat portions of the leads are brought into close contact with the electrodes. The leads are then irradiated with an optical beam so as to melt the metal pieces of the electrodes for bonding of the leads to the circuit board.
