ALUMINUM-CERAMIC JOINED SUBSTRATE AND MANUFACTURING METHOD THEREOF
To provide an aluminum-ceramic joined substrate which keeps endurance even in such a heat cycle that a high temperature is reached, and which is superior in the characteristic of heat cycle resistance, and a manufacturing method thereof.SOLUTION: Provided is an aluminum-ceramic joined substrate comprising an aluminum plate for circuit pattern directly joined to one face of a ceramic substrate, and an aluminum base plate joined to the other face. An aluminum alloy used therein contains: at least one element selected from a group consisting of nickel and iron, which is 0.05 mass% or more and 3.0 mass% or less in total; at least one element selected from a group consisting of titanium and zirconium, which is 0.01 mass% or more and 0.1 mass% or less in total; at least one element selected from a group consisting of boron and carbon, which is 0 mass% or more and 0.05 mass% or less in total; and the balance consisting of aluminum.SELECTED DRAWING: Figure 1
【課題】高温になるヒートサイクルにおいても耐久性がある、耐ヒートサイクル性に優れたアルミニウム－セラミックス接合基板およびその製造方法を提供する。【解決手段】セラミックス基板の一方の面に回路パターン用アルミニウム板が直接接合するとともに、他方の面にアルミニウムベース板が直接接合したアルミニウム－セラミックス接合基板であって、用いられているアルミニウム合金が、ニッケルおよび鉄から選ばれる少なくとも一の元素を総量で０．０５質量％以上３．０質量％以下含有し、チタンおよびジルコニウムから選ばれる少なくとも一の元素を総量で０．０１質量％以上０．１質量％以下含有し、ボロンまたはカーボンから選ばれる少なくとも一の元素を総量で０質量％以上０．０５質量％以下含有し、残部がアルミニウムからなるアルミニウム合金であるアルミニウム－セラミックス接合基板を提供する。【選択図】図１
