摘要： 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.

摘要： A higher speed moving device moves a capillary at high speed. A low inertial moving and pressing device moves and presses the capillary with low inertia. The high speed motion, and the moving and pressing motion with the low inertia are carried out independently of each other. Thus, an inertia at the low inertial moving and pressing device is reduced, whereby an impact force when a melt ball is driven by the low inertial moving and pressing device into contact with an electrode of a semiconductor integrated circuit is restricted, thus enabling stable formation for minute bumps. On the other hand, operations other than pressing the melt ball to the electrode and joining the melt ball are conducted by driving the capillary by the higher speed moving device, so that productivity is improved.

The bump bonding method comprises forming a gold ball (16) at the tip of a gold wire (1) that is inserted through a capillary (3), lowering the capillary (3) while using a displacement detection sensor to detect the vertical displacement of the capillary (3), detecting the position of that portion of an IC (11) in which an electrode is formed, based on the displacement of the capillary (3) detected by the displacement detection sensor when the gold ball (16) abuts the IC (11), pressing he gold ball (16) against the electrode forming portion to form a bump pedestal (17), elevating the capillary (3) a specified amount while moving it in the horizontal direction a specified amount, setting the height S of a position at which the capillary (3) is stopped based on the height H1 of the bump pedestal (17) detected by the displacement detection sensor, again lowering the capillary (3) down to the stop position height S to join the gold wire (1) to the bump pedestal (17), and then lifting the gold wire (1) to break the joint between the bump pedestal (17) and the gold wire (1).

摘要： A bump leveling method and a bump leveling apparatus in which the leveled height of bumps can be made constant and meet the change in thickness of an IC chip. A pressing force under which one bump is deformed to a prescribed height is measured. Thus, the pressing force under which a plurality of bumps can be deformed and leveled can be set. A load cell detects that a prescribed pressing force is exerted on the bumps and this pressing force is maintained, so that the plurality of bumps can be leveled up to the same prescribed height.

摘要： An electrode terminal (5) provided on a surface of a semiconductor chip (4) has a square shape in plane view. Further, the projecting apex portion (8a) of a bump (8) provided on the electrode terminal (5) orients to a corner portion (5a) of the electrode terminal (5). Hereupon, a gold ball (2a) formed by melting the lower end portion of a gold wire (2) supplied through a capillary (1) is joined to the electrode terminal (5), and then the capillary (1) is moved in the direction of a diagonal line of the square electrode (5). Thus, the main portion of the gold wire (2) is separated from the gold ball (2a) so that the bump (8) is formed.

摘要： In a bump bonding technique for forming a bump on an IC, including forming a ball at the tip of a gold wire protruding from a capillary, and providing a metal-to-metal joint by applying ultrasonic vibration from a ultrasonic head through the capillary while pressing the ball against a pad portion on the IC, the metal-to-metal joint is provided by applying the ultrasonic vibration at a frequency in a range of 130 to 320 kHz, more preferably in a range of 170 to 270 kHz, and most preferably at a frequency of 230±10 kHz at room temperatures and atmospheric pressure. Consequently, a bump is formed on an IC having a low heat resistance temperature in a satisfactory joint condition, and a bump is formed with good positional accuracy without giving the influence of heat to the surroundings.
