发明名称 MANUFACTURE OF SEMICONDUCTOR DEVICE
摘要 PURPOSE:To stir always a conductive paste and to prevent the components of the paste from separating by a method wherein a ball made of a magnetic substance is put in a cylinder container along with the paste, a magnet is arranged on the periphery of the container and the container is moved up and down. CONSTITUTION:A container is lowered down to a position in the lower limit and a conductive paste 4 is dripped; when the container is raised to a position in the uppermost limit, an iron ball 2, which is a ball made of a magnetic substance, results in moving in a cylinder container 3 by the effect of a magnet 1. In such a way, during the vertical movement of the container 3, the ball 2 made of a magnetic substance is held at s constant position by the magnet 1. Thereby, the interior of the paste results in being stirred relatively and a separation of the components of said conductive paste in the container can be prevented.
