本発明は超多ピンのピングリッドアレイICパラゲージ
のように高密度配線を存する多層基板の製造法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a multilayer board having high-density wiring, such as a pin grid array IC parameter with a large number of pins.
結晶化ガラスは、熱膨張係数がシリコンに近く・誘電率

ス・セラミック措造の製造方法が開示されている。Crystallized glass has properties such as a coefficient of thermal expansion close to that of silicon and a low dielectric constant (and can be fired at low temperatures), so it is possible to use crystallized glass as a main component or contain it as an insulating substrate. , high-density wiring boards using low-melting point, low-resistance metals such as Ag and Cu as conductor materials are in the spotlight.
As seen in Japanese Unexamined Patent Publication No. 55-12899, "After printing a pattern using copper paste on the surface of a green sheet made of glass particles that crystallize at a temperature lower than the melting point of copper, and laminating and integrating, A method of manufacturing a glass-ceramic structure is disclosed, which involves firing in a predetermined atmosphere.

Mn0z 12重量%以下及びAg、o 8重■以下の
うちから選ばれる一種以上とでなるものとし、導体部の
基密性を高めることが発明された。In Japanese Patent Application No. 61-294459, the composition of this copper paste is 80% by weight or more of copper or copper oxide based on copper,
It has been invented to improve the density of the conductor portion by combining MnOz with 12% by weight or less and one or more selected from Ag, O with 8 weight% or less.
しかし同多層基板の最上部のパターンの銅ペーストの接
着強度は0.5Kg/mn+”であり、この接着強度を
高めることが要請されている。However, the adhesive strength of the copper paste in the uppermost pattern of the multilayer board is 0.5 Kg/mn+'', and there is a need to increase this adhesive strength.
本発明はこの問題点を解決することを目的とする。The present invention aims to solve this problem.
問題点を解決するための手段
本発明は4体ペースト中の導体成分として、銅及び酸化

にある。Means for Solving the Problems The present invention uses one or more selected from copper and copper oxide as a conductive component in the four-piece paste, with copper as the standard.
weight or more, the balance is MnO2, 122 weight or less, 8g2O
8% by weight or less, and at least 3% by weight of one or more selected from Ti1t and Ti1h.
4体ペースト中の銅及び酸化銅は、グリーンシートとと
もに還元雰囲気で加熱還元され、焼成されて導体化する

液相を銅粒子間の境界に局部的に形成し、銅粒子同志を
緻密に焼結させる。Copper and copper oxide in the four-body paste are heated and reduced together with the green sheet in a reducing atmosphere, and are fired to become a conductor. Its content was 777 lz or more based on copper. At the same time, MnOt is reduced to MnzO*
, MnO or Mn, and improves the wettability of copper with ceramic or crystallized glass in the substrate. However, the content is 1
If it exceeds 2.2% by weight, it will prevent sintering of the copper particles and cause leakage failure or increase in resistance, so it was set to 12% by weight or less. A liquid phase of a Cu-Ag alloy called wax is locally formed at the boundaries between copper particles, and the copper particles are densely sintered together.
但しその含有■が8重量%を超えると上記銀ろうが基板
、上で玉となってしまい、基板との密着強度の低下を招
来するので8重量%以下とした。However, if the content (1) exceeds 8% by weight, the silver solder will form beads on the substrate, resulting in a decrease in adhesion strength with the substrate, so the content was set to 8% by weight or less.
又、TiO2又はTi1lzはメタライズ中よりセラミ

ぎる。Furthermore, TiO2 or Ti1lz diffuses into the ceramic from the metallization, increasing adhesive strength. However, if their content exceeds 3% by weight, the amount of diffusion into the ceramic becomes too large, resulting in a decrease in insulation resistance and withstand voltage. Moreover, the metallization also becomes porous, and the conductor resistance becomes too large.
