摘要： PURPOSE:To provide paste for metallization of ceramics, being excellent in printability. CONSTITUTION:A first disclosure is made to the viscosity and thixotropy index of paste for metallization, comprising solid powder and organic matter uniformly mixed with each other. In order to satisfy the disclosed conditions, a second disclosure is made to the required viscosity of the organic matter and the organic-matter content of the paste respectively. Furthermore, the organic matter is concretely provided with the preferred components thereof. A mixture of copper powder and glass powder in particular is effectively used for components of the solid powder on the other hand, and more preferably the grain diameter of the copper powder is defined. A thick film formed through a screen printing process can accordingly be controlled in the desired shape thereof without difficulty.

摘要： PURPOSE:To provide a composition for metallization suitable for a ceramic substrate, in particular, the one consisting of aluminium nitride as a main component utilized for a ceramic package or a hybrid integrated circuit (hybrid IC). CONSTITUTION:In a composition consisting of copper powder and glass powder for metallization, mixed powder consisting of bismuth oxide, silicon oxide, boron oxide, lead oxide, and aluminium oxide, is primarily melted and is glazed, and this is used as the glass powder. At least any one of oxides of chrome, calcium, zinc, and of titanium is added to the glass powder and they are mixed together, to stabilize bismuth. Metallization of excellent adhesion and of good solder wettability can thus be carried out without carrying out a special preliminary process for a substrate of aluminium nitride.

摘要： PURPOSE:To enhance bonding strength by restraining one end of a metallic base plate and holding the other end thereof with a spring body and arranging the ceramics pieces via brazing material and fitting a presser plate thereon via the spring body and thereafter heating the whole body to braze it. CONSTITUTION:A base plate 2 made of metal is fixed to a fixed frame 5 made of stainless steel so that the base plate 2 can be extended and contracted to the directions of the sides 2c, 2d by a heat resistant spring body 6. Brazing material 21 is interposed on this base plate 2 and the ceramics pieces 1 such as metallized Si3N4 are arranged. A heat resistant spring body 3 is placed on the ceramics pieces 1 and a presser plate 4 is fitted thereon. This presser plate 4 can be extended and contracted to the directions of the sides 4c, 4d by a heat resistant spring body 7 and furthermore is fitted to the fixed frame 5 so that it can be raised by a heat resistant spring body 3. Then the whole body is introduced into a furnace in this state and heated at about 840 deg.C for about 30 minutes in the argon atmosphere to perform brazing and joining and thereby a composite body of ceramics and metal is obtained.

摘要： PURPOSE:To join a ceramic to a metal without producing cracking, etc., by interposing a gap member having a cushioning function between the sides of adjacent ceramic pieces when many pieces are brazed onto a metallic base. CONSTITUTION:Many ceramic pieces 1 are placed on a metallic base 4 (e.g., an iron base) with a solder 2 in between. The gap member 5 (e.g., a copper sheet) having a cushioning function is interposed between the sides of adjacent ceramic pieces 1, and the base 4 is thermally joined to the ceramic piece 1. As a result, the joined ceramic piece 1 on the base 4 is not compressed by the adjacent piece 1, hence cracking is not produced with the contact point between the ceramics 1 as a starting point, the ceramic 1 is not broken and released, and a sound joined body can be produced.
