本発明ははんだ電極付半導体素子(以下半導体チップと

おおっておくことを特徴とする。The most common method for mounting semiconductor chips with solder electrodes is the method developed by IBM (Japanese Patent Publication No. 48-1654). In this method, in order to perform solder reflow bonding with the solder electrodes of the semiconductor chip, a part of the solder pedestal is formed in advance at the electrode connection part of the insulating substrate, and at the same time, part of the solder pedestal is covered with a material that cannot be wetted by solder. It is characterized by keeping it.

This is called the -1ed Co11apse Bonding) method, and in reality, as shown in FIG.
2 is formed, and the glass film 14 is covered except for the joint portion 18. After this, the solder pedestal 1 is further immersed in the solder bath.
form 5. Then, as shown in FIG. 1(b), the semiconductor chip 17 with the solder electrode 16 attached thereto is aligned on the pedestal 15, and the solder is reflowed and connected by heating to a temperature above the melting point of the solder.

る”くわれ”現象のためにはんだリフロー条件が不適当
の場合や、高温に長く置かれた場合に、接合部の強度が
劣化し、ひどい場合には破断することである。The problem with this method is that the solder reflow conditions are inappropriate due to the so-called "depression" phenomenon in which the Ag in the Ag-Pd conductor is diffused into the solder and the Ag-Pd layer is gradually reduced, or when the solder is exposed to high temperatures. If left for a long time, the strength of the joint will deteriorate, and in severe cases, it will break.

接合強度が劣化しないようにされた電極接続部を有する
絶縁基板を提供することである。An object of the present invention is to eliminate the problems of the above-mentioned conventional method and to provide an insulating substrate having an electrode connection portion that prevents the bonding strength from deteriorating even at high temperatures.

A semiconductor chip 17 having a solder electrode 16 attached thereto is prepared. The amount of the solder 16 is controlled as necessary.

の酸化を防ぎ。According to the insulating substrate of the present invention described above, the tungsten of the substrate example and the nickel film covering the surface of the substrate hardly react with solder, so even if left at high temperatures, the strength of the joint does not deteriorate and reliability is maintained. High bonding can be obtained. In addition, the gold plating applied on the nickel plating prevents the nickel plating film from oxidizing.

Moreover, instead of gold plating, tin, lead, solder silver, etc. with good solderability may be used, and the ceramic substrate may be manufactured by a dry method.
