Abstract
PURPOSE:To manufacture metal die with no burrs by fixing one of the surfaces of a metal die material to a slice table, affixing a slice plate to the other surface, and cutting this metal die material in the X and Y directions on a plane and also cutting in the X direction of plane again. CONSTITUTION:Different types of metal 3 are plated on the front and rear sides of a large size metal plate 2 as a metal die material 1A, which is affixed to a slice table 5 with adhesive 4, and a slice plate 6 is stuck to the oversurface with adhesive 7. The metal die material 1A and slice plate 6 are cut perfectly by dicing first in the X direction in plane and then Y direction in plane to yield a plurality of metal dice. At this time, a burr 8 is generated in the Y direction as cut afterward, so that dicing is made again in the X direction to cut off the burr 8 protruding into the cut groove in X direction. Thus metal dice with no burrs are manufactured, wherein no inclination will occur at the time of die bonding, which should enhance the reliability of the wire bonding strength.
