Method of producing a semiconductor device

Номер: GB0002271073A
Принадлежит:

Electrical connection to an A1 electrode of a semiconductor is made by the attachment of a copper wire. A copper ball 8a formed by flaming out one end of a copper wire 8 is moved downward to an A1 electrode pad 5 on a semiconductor chip and brought into contact for less than 150 ms. Plastic deformation then occurs so that the copper ball is pressed to the aluminium electrode pad in such a manner that the height of the copper ball (h, Fig. 8) is 25 mu m or less. It is therefore possible to decrease the work hardening property of the Cu ball and prevent A1 exclusion when the Cu ball is bonded to the A1 electrode pad. ...

A semiconductor device capable of preventing contact between electrode terminals and a die pad as well as capable of surely performing wire bonding to the electrode terminals. A passive component is formed such that a vertical height of each electrode terminal is higher than that of an element part. More specifically, each cross-sectional area of the electrode terminals is slightly larger than that of the element part. Therefore, an upper part and lower part of each electrode terminal are slightly higher than (project from) the element part. Through an adhesive, the passive component is fixed such that the element part is located on the high position part so as to be nearly parallel to a substrate surface. Further, a part of each electrode terminal (bottom part) is located in each space within concave parts. Thus, a predetermined space is formed between each of the electrode terminals and the die pad.

A B S T R A C T A contact structure for securing a semiconductor substrate to a mounting body in a semiconductor device. A multi-layered electrode formed on a surface of the semiconductor substrate, the multi-layered electrode comprising a chromium-nickel alloy layer formed on the surface, a nickel layer formed thereon and a noble metal layer selected from the group consisting of gold, silver, palladium and platinum formed further thereon, a solder layer, and a mounting means for holding the semiconductor substrate thereon, the solder layer soldering the multi-layered electrode to the mounting means, thereby bonding the semiconductor substrate to the mounting means. The foregoing construction has the features that there are substantially no voids at the solder layer as a result of good wetting of the noble metal to the solder layer; that the effective bonding area increases as a result of decrease of voids, resulting in decrease of thermal resistance by 10 to 20%; that secondary breakdown voltage increases by about 10%, thereby increasing reliability; that the bonding force is drastically increased; that process control in the soldering step becomes easier; that undesirable Sn-Ni formation is suppressed, thereby improving resistivity to thermal fatigue; and that oxidation of the surface of the multi-layered electrode is eliminated, thereby eliminating the necessity for preliminary treatment before soldering.

A semiconductor device capable of preventing contact between electrode terminals and a die pad as well as capable of surely performing wire bonding to the electrode terminals. A passive component is formed such that a vertical height of each electrode terminal is higher than that of an element part. More specifically, each cross-sectional area of the electrode terminals is slightly larger than that of the element part. Therefore, an upper part and lower part of each electrode terminal are slightly higher than (project from) the element part. Through an adhesive, the passive component is fixed such that the element part is located on the high position part so as to be nearly parallel to a substrate surface. Further, a part of each electrode terminal (bottom part) is located in each space within concave parts. Thus, a predetermined space is formed between each of the electrode terminals and the die pad.

As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.
