Such as, can utilize the physical vapor deposition (PVD) of sputtering, ion plating etc. that cushion is formed together with adhesive linkage.
Preferably, the hardness of cushion goes the mode uprised to change with ceramic layer 20 side that metal base 10 lateral stiffness low from hardness is high.Such as, when cushion 31A, 31B of such as Fig. 3, lit-par-lit structure as shown in Figure 5, low by the hardness of the cushion 31B making hardness ratio ceramic layer 20 side of the cushion 31A of metal base 10 side, hardness can be made periodically to change.In addition, when cushion 31 of monolayer constructions will as shown in Figure 4, by making composition change on the thickness direction of cushion (such as reducing nitrogen concentration along with near metal base 10), hardness can be made to change continuously.
Cushion such as comprises M-A system, and (M is titanium, chromium, nickel, zirconium, aluminium or silicon, and A is nitrogen, carbon or oxygen.) nitride, carbide, oxide.
Adhesive linkage is such as made up of the oxide of the metallic monomer of titanium, chromium, nickel, zirconium, yttrium, aluminium, silicon, the mixture of these metallic monomer or above-mentioned metallic monomer or the oxide containing multiple above-mentioned metallic monomer.
The raw material of raw material and the formation adhesive linkage selecting to form cushion can be suitable for and it is combined.In addition, the thickness (total) of cushion is 0.2 μm ~ about 5 μm.
Next, utilize Fig. 6, the raising of the release property of embodiments of the invention is described.Fig. 6 is the shaping actions finishing die (metal base being implemented to the finishing die of hard chromium plating) of the finishing die of one embodiment of the present of invention and comparative example being carried out to pre-determined number, evaluates by measuring each knockout press the experimental result that release property obtains.
Learn with reference to Fig. 6, adopt the finishing die of embodiments of the invention, compared with the finishing die of comparative example, knockout press reduces, and utilizes ceramic layer 20 to form the finishing die of release property excellence.
Next, utilize Fig. 7, Fig. 8, the raising of the soil resistance of embodiments of the invention is described.Fig. 7, Fig. 8 represent the photo using the finishing die of embodiments of the invention and the finishing die of comparative example to carry out the bottom surface of this finishing die after the shaping actions of pre-determined number (Fig. 7: 1000 times, Fig. 8: 300 times).
With reference to Fig. 7, Fig. 8, significant spot can not be recognized carry out 1000 shaping actions in the finishing die (Fig. 7) of embodiments of the invention after, on the other hand, in the finishing die (Fig. 8) of comparative example, after carrying out 300 shaping actions, except recognizing the adhesion of resin in A portion, identify the accumulation of die forging burr in addition in B portion.And, recognize variable color in whole die cavity bottom surface.Learn from above result, ceramic layer 20 can be utilized to form the finishing die of soil resistance excellence.
So, adopting the finishing die of present embodiment, by the finishing die using ceramic layer 20 to form release property and soil resistance excellence, and by using metal base 10, the crackle of finishing die, defect can be suppressed.And, utilize intermediate layer 30, the joint construction between metal base 10 and ceramic layer 20 can be improved, and suppress that ceramic layer 20 cracks, ceramic layer 20 is peeled off from metal base 10.
In addition, above-mentioned finishing die such as can be used in injection molding forming, transfer modling is shaped, compression molding.
When transfer modling is shaped (or compression molding), can resin material be used, the semiconductor chip making to be installed on substrate in the die cavity being provided with ceramic layer seal molding (or compression molding) in the packaging part (formed products) corresponding with the shape of this die cavity.
Above, embodiments of the present invention are illustrated, but should think that embodiment of disclosure is all illustrate but not limit in all.Represent scope of the present invention by claim, scope of the present invention can think all changes in the meaning and right that comprise and be equal to claim.
