摘要： Balls are sucked onto a carrier board so as to be temporarily arranged in a ball arrangement region of the board, and then the balls are transferred and bonded onto an objective substance with their positions being adjusted. Gas blow is applied to the temporarily arranged balls or alternatively the temporarily arranged balls are sucked, so as to remove excess balls other than balls that have been exactly sucked onto the ball arrangement region. Cooperation with application of fine vibration to the carrier board makes the removal of the excess balls more efficient.

摘要： A spherical semiconductor device includes a spherical semiconductor element having one or more electrodes on its surface. Spherical conductive bumps are formed at the positions of the electrodes. The electrodes are so arranged as to contact a common plane. Spherical bumps constituting a group to be connected to the outside protrude above the spherical semiconductor element such that a predetermined gap is formed between a plane or a spherical surface capable of contacting the spherical bumps and the surface of the spherical semiconductor element. The spherical semiconductor device is connected to various circuit boards or another semiconductor device through the spherical bumps. This affords easy and accurate electrical connections to the outside.

摘要： A ball-arranging substrate comprising a substrate with a main surface, a plurality of ball-arranging holes formed on the main surface for sucking and holding minute electroconductive balls at the locations corresponding to those of electrodes formed on a semiconductor device or a printed circuit board, wherein when light illuminates the ball-arranging surface to allow optical recognition of the arrangement of the minute electroconductive balls by means of the light reflected by the minute electroconductive balls and by the main surface, the wave length of the light of the light source is set in the range of 300 to 900 nm, and the reflectivity is made not more than 50% based on the light source. A reflective mirror should be provided on the rear surface of the substrate opposite to the light source, in the case when the substrate is transparent to the irradiated light.

The low melting point metal balls (3) adhesive bonded to the respective electrodes (3) may also be reflowed to form semispherical bumps (10) before use.

摘要： Balls are sucked onto a carrier board so as to be temporarily arranged in a ball arrangement region of the board, and then the balls are transferred and bonded onto an objective substance with their positions being adjusted. Gas blow is applied to the temporarily arranged balls or alternatively the temporarily arranged balls are sucked, so as to remove excess balls other than balls that have been exactly sucked onto the ball arrangement region. Cooperation with application of fine vibration to the carrier board makes the removal of the excess balls more efficient.

摘要翻译： 将球吸附到载体板上，以便暂时地布置在板的球形布置区域中，然后将球转移并粘合到目标物质上并调整它们的位置。 对临时布置的球施加气体吹动，或者临时布置的球被吸入，以便去除已经精确吸入球配置区域的球以外的多余的球。 携带精细振动的合作使得多余的滚珠更加有效的去除。
