In this plastic package,
As in a ceramic package, the conductor pattern and the pin cannot be connected by the via that is formed by filling the paste in which the metal powder is mixed into the through hole formed in the green sheet and firing it. As shown in FIG. The conductor pattern is connected to the pin 110 by the conductor through hole 202. The conductor through hole 202 is formed by forming a conductor layer 206, which is connected to a conductor pattern by plating, on the inner wall surface of the through hole 204 formed in the plastic package body 200 by a drill or the like. still,
The conductor layer 20 is formed around the opening of the conductor through hole 202.
A terminal land 207 connected to the conductor 6 is formed in series with the conductor layer 206. In this conductor through hole 202,
The pins 110 with the long pin portions 211 and the short pin portions 212 protruding are attached to each of both surfaces of the flange portion 210 having an area larger than the opening area. The pin 110 is usually attached by fitting by inserting the short pin portion 212 into the conductor through hole 202, or by using both the fitting and resin attachment.

In the pin 110 thus mounted in the conductor through hole 202, the short pin portion 212 inserted in the conductor through hole 202 contacts the conductor layer 206, and the terminal land 207 contacts the flange portion 210. Is connected to the conductor pattern formed on the plastic package body 200. However, recently, as the operation speed of the semiconductor chip 104 mounted on the package body 200 has been increased, the inductance and resistance of the long pin portion 211 of the pin 110 protruding outward from the bottom surface of the package body 200. Has become a problem. For this reason, the inventor has proposed that the pin 110
We also proposed to use hemispherical bumps instead of.

By using a bump instead of the pin 110, the long pin portion 2 of the pin 110 can be obtained.
It is possible to eliminate the influence of the inductance, resistance, etc. of 11. However, when a bump is used instead of the pin 110, a low melting point metal such as solder is melted and a hemispherical shape is formed on the opening of the conductor through hole 202 or in the vicinity thereof by utilizing the surface tension of the molten low melting point metal. It is necessary to form bumps. Therefore, various problems shown in FIG. 5 occur.

That is, as shown in FIG. 5A, when the bump 300 is not formed on the terminal land 207 while avoiding the opening of the conductor through hole 202, the hemispherical bump 3 is formed.
00 can be easily formed, but the area of the terminal land 207 must be increased, and the formation density of the bumps 300 becomes lower than the mounting density of the conventional pins 110. On the other hand, if the bumps 300 are not formed directly on the openings of the conductor through-holes 202, as shown in FIG. 5B, the bumps 300 whose shape has collapsed due to a portion of the low melting point metal entering the conductor through-holes 202. Is formed. Alternatively,
As shown in FIG. 5C, the low melting point metal flows along the periphery of the opening of the conductor through hole 202 to form a donut-shaped bump 300. In this way, the conductor through hole 20
It was extremely difficult to form a hemispherical bump on the second opening. Therefore, an object of the present invention is to provide a semiconductor device capable of easily forming a hemispherical bump on an opening of a conductor through hole connected to a conductor pattern formed on a package body.

As a result of repeated studies to achieve the above object, the present inventor has used a T-shaped pin in which a pin portion is erected on a collar portion, and uses the T-shaped pin's pin portion as a conductor. By inserting into the through hole and forming a bump on the flat surface side of the collar portion of the T-shaped pin that covers the opening of the conductor through hole,
The inventors have found that hemispherical bumps can be easily formed on the openings of conductor through holes, and have reached the present invention. That is, according to the present invention, in a semiconductor device in which a semiconductor chip is mounted on a package body having a conductor pattern formed thereon, a conductor layer formed along one inner wall surface of the package body and formed along an inner wall surface is formed on the conductor pattern. Into the conductor through-hole formed by connection, a pin portion of a metal T-shaped pin erected on a collar portion having an area larger than the opening area of the conductor through hole is inserted so as to come into contact with the conductor layer. In addition, a hemispherical bump made of a low melting point metal such as solder is formed on the flat surface side of the collar portion of the T-shaped pin that covers the opening of the conductor through hole. is there. The present invention having such a configuration can be suitably applied to a semiconductor device whose package body is made of plastic.

According to the present invention, since the opening of the conductor through hole connected to the conductor pattern of the package body is covered with the flange of the T-shaped pin, solder or the like is not formed on the bump forming surface of the flange which is a flat surface. When the low melting point metal is melted to form a hemispherical bump, the low melting point metal may enter into the conductor through hole, or the low melting point metal may flow in a donut shape along the opening edge of the conductor through hole. It is possible to prevent and easily form a hemispherical bump. Further, since the bump can be formed on the opening of the conductor through hole, the density of the bump can be increased.
