Description of the Invention: [Technical Field] The present invention relates to a semiconductor carrier and a method of manufacturing the same, and more particularly to a carrier board having high density and high heat dissipation and a core carrier (c〇reless Substrate). Provides high density, high yield manufacturing methods for solid microvias. [Prior Art] Due to the trend of thin and light electronic products and the increasing functions, the number of I/Os of 1C is rapidly increasing, and the relative packaging technology is constantly updated, from early plug-in to surface adhesion (SMT). Ball Array (BGA), most of today's high-end products have used the build-up method to make ic carrier boards, such as FlipChip, MCM-Multi-Chip Module BGA, with heat sink The package density of the Ic carrier (Embedded Thermal Dissipation) and the wire-free carrier (Wire-free) is also constantly increasing. However, such a high-density layered carrier requires the use of a Via Filled Plating structure, and the technical process and structure of the laser-guided micro-via re-plating, which is not only expensive in equipment investment, but also There are many disadvantages in the manufacturing method. The conventional IC carrier structure is generally a two-layer to eight-layer multilayer printed circuit board, the material used is _ or organic material, and the multi-layer structure of the line guide is mechanical drilling or laser drilling micro hole Then, with the key hole guiding method. It is not easy to check the quality of the micro-holes in the laser drill, and the shortcomings such as the slight opening of the guide hole or the 谏ierQ Via Qpen) are not easy to garble with the current planting electrical tester. When the products are sent to the customer, it is difficult to cause a disconnection after being subjected to multiple thermal stresses. When the problem is discovered, it has caused a lot of damage. 1247363 Laser drill second = skill: Compared with (== hole Ci shot hole caused by "plating = ί ΐί! ( ) 'Fig. - (D) shows the electric hole when the gas pick apricot ^ 疋 tiny hole The problems caused by the inner product (4) or the filling of the hole are all due to the sampling test. Therefore, the traditional manufacturing method is flawless (four), ίί本 and 1^reliability of the six density-added IC carrier board. It is an urgent task to develop a new chip package carrier structure and a manufacturing method to provide a solution to the problem. [Summary of the Invention] < Based on the above-mentioned lack of the conventional Lin's provided by the company, a high-density layered 1C carrier structure 'The main feature is the use of Solid Via Via with stacked Via structure. In addition to the traditional core carrier, the present invention can also be implemented on a coreless carrier to meet high density IC carrier. There is a higher demand for heat dissipation and reliability. The present invention further provides a method for fabricating a south density-increasing layer 1C carrier, the main spirit of which is to replace the conventional laser with a high-density carrier plate (Via Filled Plating). Drilling and electroplating technology to provide low cost Ic Based on the above objectives, the present invention provides a multilayer photoreceptor forming a line and a micro-via, and a metal plating column, such as a steel column, is formed by a conventional electroplating etch stripping agent and electroplating to form a solid micro-guide. Sol id Micro Via, 1247363 is further applied with a layered material and a metal connecting layer (which can be copper), and the connection surface of the micro-via is opened by the grinding method to apply a deposited metal (such as chemical copper). It can be connected to the outer layer Xilin. In this way, the metal column can provide the buffering function of the material stress change at high temperature, and can also provide high heat conduction performance. *;, _, at the same time, this method can also provide a thinner carrier board in the future. Production, such as the production of Coreless carrier plates, with a higher density of the stacked structure, and the method of filling and plating, can greatly reduce the thickness of the finished wire. This manufacturing method solves the conventional mine riding micro hole The application is missing, and it can be effective in response to the demand for the carrier board in the future without increasing the yield of the high-density chip package and reducing the manufacturing cost of the high-density layered ic carrier. Solution: It can solve the purpose, function and structure of the invention. It can be implemented and matched with the illustrations as follows: ', [Embodiment] The first picture (A) _ two ( R) is a schematic diagram of a method for manufacturing a solid micro-conductor carrier according to the present invention, wherein FIG. 3(A) and FIG. 3(E) are diagrams for fabricating a circuitized carrier, and FIG. 3(F) - Three (K) reveals the main manufacturing method of the present invention, that is, the solid micro λ!, the tilt of the via hole, and the connection layer thereon. Figure 3 ([〇县形成 another build-up circuit] and Figure 3 (Μ)-three (R) is a step of forming another solid and small via hole in the upper layer of a solid microvia to form a stacked structure. Among them, the steps of Fig. 3 (7) - 13 (κ) and 1247363 Fig. 3 (Μ) - 3 (R) are exactly the same, and can be repeated as needed to form more layers of the carrier structure. Hereinafter, the detailed production method of the present invention will be described first. As shown in the second diagrams (A) to III (e), a carrier having a circuit pattern is fabricated. First, a core substrate (Core Lami.nate) 301 having a thickness of about 0·1 to 〇.8 is provided, and a first metal layer 302 having a thickness of about 3 to 12/m is coated on the upper and lower sides thereof. On the substrate 301 is shown in Figure 2 (a). The material of the substrate is generally selected from Bismaieimide Triazine (BT) or other organic materials, or even ceramic materials. The first metal layer may be copper (Cu). Then, through the first metal layer 3〇2 and the substrate 3〇1, a core substrate through hole 3〇3 (c〇re through hole) having a width of about 1〇〇~250/zm is formed by mechanical drilling. Two (8). Then, a deposited metal layer (or re-plated thin copper) is formed, which has a thickness of about 5·5-3//m, and a through-hole signal is formed on the sidewall of the first metal layer 3〇2 and the core wire via 303. The metal layer is shown in Figure 3 (6). The metal layer can be chemical copper. Then apply the first layer of sensitization _ 3 () 5, and use the mask (Mask) side to perform image transfer to form the line, as shown in Figure 3 (9). Finally, a layer of electroplated copper and a surname 3〇6 (which can be nickel, gold, gold, etc.) can be applied, as shown in Fig. 3(E). Fig. (F) and Fig. 2 (κ) are steps for making a solid microvia. First, a first layer of photosensitive resist #丨307' is applied and image transfer is performed in a mask manner to form a micro via 308, as shown in Fig. 7 (7). Next, fill the tiny via holes with the hole-filling method !247363 to form a solid tiny via hole (s〇lid Micr〇 Via) 3〇9, as shown in Figure (6). Then, the first layer of photoresist 3 〇 5 and the second layer of photoresist 3 〇 7 are stripped, and then the via holes, the lines and the solid microvias 309 of the core carrier 301 are formed to be etched. Show. At this point, the via holes on the core carrier 3〇1, the first layer line, and the solid microvia 309 are completed. Next, only a build-up material dielectric layer 310 is applied thereto (or a sensitive layer 311 is applied over the surface of the dielectric material) as shown in Fig. 3(1). The need for copper 311 depends on the dielectric layer material used. For example, if the dielectric layer used is an organic dielectric material (such as a non-BT material (Resin) layer without a glass fiber reinforced material), then a copper foil 3 ιι is not added. Then, the dielectric layer 31〇 of the build-up material (or the copper-containing skin 311 is covered) covered on the solid micro-via 3Q9 is polished to expose the surface of the solid micro-via, as shown in FIG. . Finally, a second layer of deposited recording layer is applied (or a battery paste is formed to form a first layer of solid microvias 3 〇 9 _ conductive metal layer 312, as shown in Figure 3 (1). The deposited metal layer can be chemical copper The second figure (8)-three (8) is the step of making another layer of solid micro-conducting holes in the upper layer of a solid micro-conducting hole, and the step of forming a stacked hole structure. First, the three layers of resisting agent 313 are transferred to form a line. Electro-mineral copper 314 and side resist agent 315, as shown in Figure Sanjiang, 'this step is the same as Lang San (9) and Figure 3 (8). Then, the first drink of photosensitive resist 316 ' is applied and the image is masked. Transfer (4) into a micro-via (Micro Via) 317 ' As shown in Figure 3 (8), this step is the same as Figure 3 (f). Connected to 12437363, filling the tiny vias with hole-filling to form a solid The micro-via (Solid Micro Via) 318' is shown in Figure 3 (N), this step is the same as Figure 3 (G). Then, the second layer of photoresist 313 and the fourth layer of photoresist 316 are stripped. And etching to form the build-up dielectric layer line and the solid micro-via 318, as shown in Figure 3 (9), this step is the same as Figure 3 (H). Thus, the second layer of circuitry and the solid microvia 318 are completed. Then, a dielectric layer of a build-up material is applied thereto (or a copper foil 320 is applied over the surface of the dielectric material), as shown in FIG. As shown in p), this step is the same as in Figure 3 (1). The need for the copper foil 320 depends on the dielectric layer material used. For example, if the dielectric layer 319 is an organic dielectric layer. Material (such as non-BT material resin (hin) layer without miscellaneous addition machine), do not add - money coffee. Then grind the cover layer of solid layer 318 1 of the layered material dielectric layer 319 (or Bronze 32 〇) is ground to expose the connection surface of the solid micro-via 318, as shown in Figure 3 (8), the sequence is the same as Figure 3 (7). Finally, the third deposited metal layer is applied (or re-powered) The copper forms the second layer of solid micro-via 318 and the outer layer of the signal layer is connected to the sound of the wind (3). This step is the same as that of Figure 30. The deposited gold 曰",, seven. 5. So complete the layer Solid micro-conducting holes (ie, the second layer of micro-conducting layer is actually read __ layer, the contact of the pro-layer. Re-turning, can continue to form a layer of stacked structure Pore structure., -() Step 4 (1) - Four 〇〇 is the solid micro-guide 127393 of the coreless substrate stack structure of the present invention. The method of making the hole is not intended. As shown in Figure (4), the production of the coreless carrier is not shown. , with - copper (3 ~ 12U_1 replaced substrate, and then applied with a photoresist), and image transfer by mask (Mask) to form tiny vias (10) (10), as shown in _ (B. Then, The micro via hole is filled in a hole-filling method to form a solid micro via (Solid Micro Via) 4 () 4, as shown in Fig. 4 (6). Then, the photoresist 402 is stripped, and then, Applying only a layer of dielectric material 4〇5 (or coating the surface of the dielectric layer with copper 406), and then grinding the material over the solid microvia 404. Dielectric layer damage (or copper-containing right to rub) "to connect the solid micro-via 4,4 connection surface, as shown in Figure 4). The need for copper 406 depends on the dielectric layer material used. For example, the material of the dielectric layer 405 used for the right side is an organic dielectric layer material (for example, a resin of a non-BT material (ReSln) layer without a glass fiber reinforced material), and no copper pinna may be added. On the other hand, if the material of the electric layer 405 is BT, the force-copper 406 is not required. Further, a deposition enamel (or re-plated copper) is applied to form a solid via hole 4 〇 4 of the substrate and a signal conducting metal layer 407 of the outer wiring layer, as shown in FIG. φ a then 'apply the first layer of photoresist on the side, and in the form of a mask (Mask), "like transfer of Wei Road, and then - layer of electricity and side lions (can be X, gold, · · · Equivalent metal), as shown in Figure 4 (F). Applying a second layer of photoresist 410' and transferring the image by masking to form a micro via 411, and filling the micro via with fillet plating to form a solid tiny 11 1247363 via hole (Solid Mi (V) Via) 412, as shown in Figure 4 (6). Then, the first layer of photoresist 408 and the second layer of photoresist 4 are turned off, and the via holes, the lines and the solid microvias 412' of the coreless carrier are formed as shown in FIG. 4(n). The fourth figure (7)-four (K) is a step of making another layer of solid micro-via holes in the upper layer of the solid micro-via hole to reduce the structure of the hole. First, a build-up material dielectric layer 413 (or an additive-layer copper bump 414) is applied thereto as shown in Fig. 4 (1). The need for copper 414 depends on the dielectric layer material used. For example, if the dielectric layer 413 material used is an organic dielectric layer material (e.g., a non-βτ material resin (10) coffee layer without a glass fiber reinforced material), the copper skin 414 may not be added. Then, the build-up material dielectric layer 413 (or the copper-containing skin 414 is polished) over the solid micro-via 412 is polished to expose the connection surface of the solid micro-via 412, as shown in Fig. 4 (7). Finally, the metal layer (or remineralized copper) is formed to form a solid via 412* of the outer layer of the layer of the metal layer 415, such as _(κ)_. The deposited metal layer can be chemical copper. At this point, the thickened solid small vias 412 are completed, and the solid microvias are also connected to the subsequent buildup wiring layers. Repeat the fourth figure (8) _ four (1 step, you can continue to form the layered a hole structure of the stacked structure.
