The silver ink is printed on the portion of the first circuit pattern that is designed to be electrically conductive between the layers, that is, on the electrode pads on which the bumps 30 are to be formed. As shown in Fig. 5, by the silver ink being hardened, the conductive bumps 3 can be formed on the first circuit pattern. In the present embodiment, although the silver ink is exemplified, the conductive material (4) such as the conductive material can be made; ^ In the step S130, as shown in the sixth figure, the first circuit pattern 1C is used. A laminated insulating material 40. By the insulating material 4 is laminated: the first circuit pattern is buried in the insulating material. The first circuit 薗 M 4n Μ an I-way pattern 1G can be filled with the insulating material 40. The "existence" of this embodiment can be laminated in a semi-hardened state at 201002168. Therefore, the first circuit pattern can be buried in the insulating material. Further, although the insulating material is laminated, the insulating material is penetrated by the conductive bumps. As shown in Fig. 6, the insulating material 40 is penetrated by the bumps 30, and the upper end of the bumps 30 is exposed to the outside of the insulating material. In the step S140, as shown in Figs. 7 to 9, a second circuit pattern 20 is formed on the insulating material 4?. In the step S 141, as shown in Fig. 7, a conductive layer 62 is laminated on the insulating material and the bumps 30.

In the present embodiment, the conductive layer 62 and the -metal|54 are formed of steel (Cu). The conductive layer 62 and the first metal layer 54 are etched by supplying a solution of the copper (Cu) metal layer by the energy source: 201002168. In the etching process, it is optional to etch the electric layer 62 which is not shattered by the etching photoresist 64, and the first metal layer can be removed, and the copper (Cu) metal layer can be left. (d) solution, can not (four) formed by the second metal ^ 56. Even if the first metal layer 54 is removed, the second metal layer 56 is not affected by the (iv) solution (four). Therefore, the first circuit pattern 10 is grown by the second metal > 56 without being etched. - As shown in Fig. 9, after the surname process, the second circuit pattern 20 can be formed on the insulating material 4 by stripping the silver engraved photoresist 64. Next, in P white & S150, as shown in Fig. 1, the second circuit pattern 20' is pressed to cause the second circuit pattern to be buried in the insulating material 4''. As shown in Fig. 9, the second circuit pattern is exposed from the insulating material. If the flattening process is performed in the state in which the second circuit pattern is exposed, and the second circuit pattern is buried in the insulating material, the insulation reliability between the patterns can be made. Next, in step S160, as shown in Fig. 11, the second metal layer 56 covering the i-th circuit pattern 10 is removed. By with the first metal;! The second metal layer 56 formed by the 54 different materials is not etched during the formation of the second circuit pattern 2, protecting the first circuit pattern. According to the present embodiment, the second metal layer 56 made of nickel (Ni) can be removed by etching the first circuit pattern of the copper (Cu) material and the etching solution of the second circuit pattern 20. As shown in FIG. 5, the second metal layer can be removed using an etching solution that etches only the second metal layer 56 by 1±. If the first circuit pattern is in accordance with the first embodiment of the present invention, 11 201002168 Semi-additive method to achieve high-density shape of 10/10~15/15/zm (line width/line spacing; Line/Space) 'The second circuit pattern 2〇 can be realized by Subtractive method 20/ 20 to 25/ 25 // m (line width/line spacing; Line/Space).

Therefore, it is possible to realize a fine circuit pattern and a high-density circuit pattern, and it is possible to reduce the expensive desmear and electroless steel plating labor required in the semi-additive method. In addition, the process time required in the electrolytic plating process can be reduced. Further, as shown in Fig. 11, by embedding the insulating material 4 in the first circuit pattern and the second circuit pattern 20, it is possible to provide a printed circuit board which is thinned and has improved insulation reliability.

The carrier 5, which is joined to the insulating material 40 and the first-circuit pattern, can be separated from the insulating material and the first circuit pattern by the high-temperature high-rise process. That is, after the layering process of the conductive layer 82 in the stage (10), the carrier 5 is removed. In the step S343, as shown in Fig. 30, (4) light @84 is formed on the conductive layer 82 and the first circuit pattern 1G. According to the first embodiment, the moon-shaped photoresist 84 can be formed by performing a lithography process on the photosensitive material deposited on the conductive layer 82. Further, the first circuit pattern 1 and the insulating material 40 are covered by the etching photoresist 84. On the other hand, the etch photoresist 84 partially covers the conductive layer 82. That is, the etch photoresist 84 covers only a portion of the conductive layer 82 corresponding to the first first pass pattern 20. In the Slave S344, as shown in Fig. 3, an etching solution is supplied in a state where the etching resist 84 is formed, and the conductive layer 82 is selectively etched. The first circuit pattern 10, the insulating material 40, and a portion of the conductive layer 82 covered by the etched photoresist 84 are not etched. As shown in Fig. 31, after the etching process, if the etching photoresist 84 is removed, the second circuit pattern 2 is formed on the insulating material 40. 18 201002168 Then in stage S350, as shown in Fig. 32, the second pattern 20 is pressurized, and the circuit pattern is buried in the insulating material 40. As shown in Figure 31, the circuit pattern is exposed on the insulating material, and the flattening process is performed under the shape of the second circuit pattern. The insulation reliability by embedding the insulating material in the second circuit pattern can be improved. According to the third embodiment of the present invention, by forming the pattern 10 and the second circuit pattern 2 by the subtraction method, the expensive desmear and electroless copper plating required in the semi-additive method can be reduced. Time. In addition, the process time required in the electrolytic chain process can be reduced. The first circuit pattern 10 in the third embodiment of the present invention is formed by an etching process. Therefore, in the (four) process characteristics, the width of the pattern on the outer portion of the 胄tb is formed to be larger than the width of the lower portion of the pattern buried in the insulating material 40. That is, the cross section of the circuit pattern by the side etching is trapezoidal. By the width of the upper portion of the first circuit pattern 10 being formed wider, the bonding area of the wire bonding wire bonding can be made wider. Therefore, the reliability of wire bonding can be improved. Further, as shown in Fig. 32, by embedding the insulating material 4 in the first circuit pattern and the second circuit pattern 20, it is possible to provide a printed circuit board which is thinned and has improved insulation reliability. The above has been described with reference to the preferred embodiments of the present invention, but it should be understood that those skilled in the art can devise without departing from the spirit and scope of the invention as described in the appended claims. The present invention has been variously modified and changed within the scope. 19 201002168 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a flow chart showing a method of manufacturing a printed circuit board according to a first embodiment of the present invention.
