INK TANK PIPE OF INKER FOR SEMICONDUCTOR TEST EQUIPMENT

摘要

PURPOSE: An ink tank pipe of an inker for semiconductor test equipment is provided to dot properly an ink on a surface of a wafer by preventing a spreading phenomenon of ink formed on a lower portion of ink tank pipe. CONSTITUTION: An ink tank pipe(27) has a concave groove(27a) formed on a lower face of the ink tank pipe(27). The concave groove(27a) prevents a spreading phenomenon of ink to a surface of a wafer(18) in an ink dotting process by reducing the amount of ink projected from the lower portion of the ink tank pipe(27) to a lower direction of the ink tank pipe(27). The concave groove(27a) of the ink tank pipe(27) has a streamline shape.
