Definitions
- the present invention relates to a circuit wiring board with a built-in heat-resistant substrate, and more particularly, to a circuit wiring board with a built-in heat-resistant substrate suitable for a package substrate on which an IC chip is mounted.

- a multilayer printed wiring board in which conductor layers are connected by via-hole conductors is disclosed.
- JP 2001-102479 discloses an interposer for electrically connecting an IC chip and a package substrate.
- the interposer body 20 in FIG. 2 is silicon, and an IC chip electrode is connected to a via conductor 27 penetrating the silicon, and a wiring layer is formed on a silicon substrate opposite to the IC.
- Patent Document 1 JP 2002-344142
- Patent Document 2 JP 2001-102479
- An object of the present invention is to provide a heat-resistant circuit board built-in circuit wiring board capable of realizing finer. Another purpose is to increase the yield of electronic components and reduce the manufacturing cost of electronic components by incorporating a wiring layer of electronic components (eg, IC chips) onto a heat-resistant substrate. Another object is to reduce the coefficient of thermal expansion of the entire circuit wiring board with a built-in heat-resistant substrate.
- a wiring board particularly a circuit wiring board with a built-in heat-resistant substrate.
- it improves the electrical connection reliability between the built-in heat-resistant board and the built-in wiring board with built-in heat-resistant board, and prevents peeling between the two to prevent the insulation layer of the built-in wiring board
- the purpose is to prevent cracks in the conductor layer.
- the inventors of the present invention are a heat-resistant substrate built-in wiring board comprising a heat-resistant board and a built-in wiring board containing the heat-resistant board.
- a substrate is formed on the core substrate, a through-hole conductor that conducts between the front and back surfaces of the core substrate, and the core substrate, and an interlayer resin insulation layer and a conductor layer are alternately laminated, and each conductor interlayer
- the idea was to form a circuit board with a built-in heat-resistant substrate consisting of a build-up wiring layer connected by via-hole conductors.
- a build-up wiring layer can be formed on the surface of the Si substrate having excellent flatness, so that it is thinner than the resin substrate with unevenness. Conductor circuits with excellent wiring and thickness accuracy can be formed, and fine pitch circuit wiring boards can be realized.
- the build-up wiring layer is formed on the mirror-finished surface, the wiring variation is reduced and the impedance variation can be reduced.
- the density can be increased and the size can be reduced, and the thickness can be reduced by reducing the number of layers.
- passive elements such as L (inductor), C (capacitor), R (resistor), VRM (DC-DC converter) should be formed on the core substrate surface, build-up wiring layer or in the build-up wiring layer. This makes it possible to enhance the power supply and eliminate noise. Furthermore, by forming part of the rewiring layer on the IC side on the heat-resistant substrate side, it is possible to improve IC yield and manufacturing cost.
- connection pad of the heat resistant substrate can be connected by plating or the like, and the reliability can be improved. Further, since it differs from an interposer such as that disclosed in Japanese Patent Application Laid-Open No. 2001-102479, the number of connection points due to solder bumps is reduced and the number of reflows received by the board is reduced.
- the rewiring layer is formed on the core substrate having a small thermal expansion coefficient, the occupation ratio of the heat resistant substrate to the circuit wiring board with the built-in heat resistant substrate becomes larger than when the rewiring layer is not formed. As a result, the thermal expansion coefficient of the circuit wiring board with built-in heat-resistant board can be reduced compared to the case without the rewiring layer (the thermal expansion coefficient of the circuit wiring board with built-in heat-resistant board becomes the thermal expansion coefficient between the resin board and the electronic component). .
- the thermal expansion coefficient When the thermal expansion coefficient is reduced, the shear stress between the electronic component and the circuit wiring board with built-in heat-resistant board or between the heat-resistant board built-in circuit wiring board and the mother board connected to the circuit wiring board with built-in heat-resistant board is reduced.
- the connection member for example, solder
- the connection member that connects between the component and the circuit wiring board with built-in heat-resistant board or between the circuit board with built-in heat-resistant board and the mother board is less likely to break.
- the rewiring layer is formed on the core substrate, the pitch between the through-hole conductors formed on the core substrate is widened. As a result, cracks are unlikely to occur in the core substrate having a low thermal expansion coefficient.
- the core board and the through-hole conductors formed on the core board have different coefficients of thermal expansion, the core board is deformed by the through-hole conductor around the through-hole conductor. The smaller the distance between through-hole conductors, the greater the amount of deformation of the core substrate between the through-hole conductors. Further, by providing a rewiring layer, a through-hole conductor can be formed over the entire core substrate. For this reason, since the thermal expansion coefficient and Young's modulus are substantially uniform in the core substrate, the warpage of the core substrate is reduced, and peeling between the core substrate crack and the heat resistant substrate and the built-in wiring substrate can be prevented. In order to arrange the through-hole conductors substantially uniformly over the entire core substrate, it is preferable to form a build-up layer (surface rewiring layer) only on the surface of the core substrate.
- a build-up layer surface rewiring layer
- a build-up wiring layer is formed on a core substrate (thickness of about 0.3 mm) made of silicon or the like using a core substrate (thickness of about 0.8 mm) made of glass epoxy of JP-A-2002-34414. Therefore, the thickness of the circuit wiring board can be reduced (the thickness of the multilayer printed wiring board disclosed in JP-A-2002-34414 can be reduced to about 0.2 to 0.5 mm compared to about 1 mm. ), Lowering the inductance and improving the electrical characteristics.
- the thermal expansion coefficient of the circuit board with a heat-resistant substrate can be made closer to the thermal expansion coefficient of the IC chip.
- the material constituting the core substrate of the heat resistant substrate is preferably Si, but is not particularly limited.
- Ceramic substrates such as Pyrex glass (Pyrex is a registered trademark), dinorequoia, ani- nium nitride, silicon nitride, silicon carbide, alumina, mullite, cordierite, steatite, phonoresterite, and the like.
- the Si substrate is most easily and inexpensively available, so it is desirable in terms of cost.
- solder material used for the joint between an electronic component such as an IC and a circuit wiring board (package board) is not particularly limited, but S, Ie, Sn / Pb, Examples include Sn / Ag, Sn, Sn / Cu, Sn / Sb, Sn / In / Ag, Sn / Bi, Sn / ln, copper paste, silver paste, and conductive resin.
- the through hole (through hole) of the core substrate may be filled with a conductive material, or a stub conductor (through hole conductor) is formed on the inner wall of the through hole, and an insulating material or a conductive material is applied to the unfilled portion.
- a filled structure may be used.
- the conductive material to be filled in the through hole is not particularly limited.
- the conductive paste is made of a single metal such as copper, gold, silver, or Eckenole, or a metal composed of two or more kinds. It is preferable that it is filled. This is because the resistance is low compared to the conductive base, so that the power supply to the IC is smooth and the amount of heat generated is low.
