  • Patent number: 6329640
    Abstract: An object of the present invention is to provide a bump-bonding heating apparatus, a bump bonding method and a bump forming apparatus which do not involve large-sized apparatus configuration and which are easy to handle, and a semiconductor wafer in which bumps are formed by using the bump bonding method. The bump-bonding heating apparatus has a wafer turning member, a turning unit and a wafer heating unit. The turning member is turned by the turning unit without turning the wafer heating unit, whereby a semiconductor wafer mounted on the turning member is turned. Like this, since the wafer heating unit is not turned, the apparatus configuration can be made compact. Since the turning member is turned directly by the turning unit, the turning angle of the semiconductor wafer can be implemented with higher precision as compared with the conventional gas floating type turning method.

  • Publication number: 20010042771
    Abstract: Wafers are previously positioned so that the wafer orientation flat is oriented in a particular direction. A transporting means then moves and places the previously positioned wafer on a bonding stage where bumps are formed on the wafer by means of a bonding head. The transporting means has a sensor for detecting the position of the orientation flat of a wafer on the bonding stage from a position above the bonding stage, thereby avoiding the adverse effects of heat from the bonding stage during orientation flat detection.

  • Patent number: 6206066
    Abstract: A method of and apparatus for mounting an electronic component at a specified position of an object. The method includes applying a sealant in a first application process. The sealant is quickly, sufficiently and forcibly applied in the first application process simply by avoiding electrodes at the arrangement position, and tightly contacting the arranged electronic component and the object. Then the bonding of the electrodes is performed in the usual manner. A second application process is carried out by applying a sealant to the periphery of the electronic component in the same manner as in the convention method, which is sufficient to cause the sealant to flow to the sealant previously applied under the electronic component. The second application process can be accordingly conducted speedily and sufficiently. Air bubbles will not be trapped between the electronic component and the object, with the result that mounting failures due to breakage or corrosion of the electronic component can be reduced.

  • Patent number: 5899140
    Abstract: 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.

  • Patent number: 5899375
    Abstract: The object is to provide a bump bonder wherein the drop of the tact efficiency of bump formation can be reduced to a low level by discard-bonding of unsatisfactory balls (3) so that satisfactory bumps can be formed. It features arranging a discard bonding chip (19) on bonding stage (17), which holds in their prescribed positions the semiconductor chips (13a), (13b) that are to be subjected to bump formation and performing discard bonding to discard bonding chip (19). Due to this construction, discard bonding can be effected without needing to move the capillary far from the bonding stage (17), which is the working position.

  • Patent number: 5667130
    Abstract: An ultrasonic wire bonding apparatus and method is capable of maintaining a sufficient clearance between the horn and bonding surface, and thereby increase the working area without using a long horn. In the ultrasonic wire bonding apparatus, a capillary is located at the front end of a horn for holding a wire that is directly supported at the front end of the horn. The capillary is long enough to maintain a sufficient clearance between the horn and the bonding surface. Alternatively, a capillary, which is located at the front end of a horn for holding a wire, is short and is supported at the front end of the horn through a joint or extension. The total length of the joint and the capillary is enough to maintain a sufficient clearance between the horn and the bonding surface.
