    • PURPOSE:To position a chip with high accuracy regardless of the transparency or opacity of a substrate by each observing the chip and a substrate surface, with which the chip is bonded, directly by a camera. CONSTITUTION:The chip 2 is photographed to an observing monitor 56 by the camera 51 and positioned roughly, and a collet 40 falls from a section just above an adsorbing position 28, adsorbs the chip and rises, and is positioned just above the camera 55 and is stopped. The surface of bumps 2a of the chip is photographed to the monitor 56 through the camera 55. The bonded pads 1a of the substrate 1 are overlapped to the image of the chip 2 and photographed by the camera 53 at the same time, and the bumps 2a and the pads 1a are positioned. The collet 40 is moved only by the quantity of offset l, is positioned at a section just above a bonding position 38 and falls, and the chip 2 is bonded with the substrate 1. The chip is bonded, and the collet rises, and is moved on the adsorbing position 28 again. The next chip 2 is positioned at the position 28 at the same time. Accordingly, both transparent and opaque substrates can be positioned with high accuracy by simple constitution in which a special projector is not set up.
    • 目的:无论基板的透明度或不透明度如何,都可以通过相机直接观察芯片和与芯片结合的基板表面,高精度定位芯片。 构成:通过照相机51将芯片2拍摄到观察监视器56并且被大致定位,并且夹头40从刚好在吸附位置28上方的部分落下,吸附芯片并上升,并且位于相机55的正上方,并且 被停止 将芯片的凸块2a的表面通过照相机55拍摄到监视器56.衬底1的接合焊盘1a与芯片2的图像重叠并同时由照相机53拍摄,并且凸块 2a和垫1a定位。 夹头40仅移动偏移量l,位于键合位置38正上方的一部分,并且下降,芯片2与基板1接合。芯片被接合,并且夹头上升,并且是夹头 再次在吸附位置28移动。 下一个芯片2同时位于位置28。 因此,通过简单的构成,可以高精度地定位透明和不透明的基板,其中不设置专用投影仪。
