Abstract

PURPOSE:To enable a wiring pattern provided around an insulating circuit board to be electrically insulated from an island by a method wherein an anisotropic conductive paste conductive only in a direction which crosses the underside of an insulating circuit board and a wiring pattern formed on the upside of the insulating circuit board and connected to the anisotropic conductive paste through the intermediary of a through-hole are provided. CONSTITUTION:The underside of an insulating circuit board 21 is bonded to an island 22 with an anisotropic conductive paste 23. A wiring pattern 24 is formed on the upside of the insulating circuit board 21. A through-hole 25 is provided to the insulating circuit board 21. The wiring pattern 24 is connected to the anisotropic conductive paste 23 through the intermediary of the through- hole 25. At this point, when the insulating circuit board 21 is bonded to the island 22, as the underside of the insulating circuit board 21 is pressed against the anisotropic conductive paste 23, conductive fillers 30 contained in the paste 23 are made to come into contact with each other primarily in a direction which intersects the underside of the board 21. By this setup, other wiring patterns exposed at the cut plane around an insulating circuit board can be electrically insulated from an island.

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention particularly relates to a hybrid semiconductor device having an insulated circuit board on which a wiring pattern is formed.

Here, FIG. 4 is a plan view of the insulated circuit board, FIG. 5 is a sectional view taken along line xx' in FIG. 4, and FIG. 6 is a sectional view taken along line Y-Y' in FIG. 4.

Therefore, before adhering to the island, this plating line portion must be cut with a mold. However, after cutting with the die, the plating line 4 is exposed on the cut surface (see FIG. 5). For this reason, a conductive paste, such as a conductive paste for bonding a semiconductor chip to an island, cannot be used as the paste for bonding the insulated circuit board 1 to the island. This is because the conductive paste may adhere to the plated wire 4 due to the conductive paste spilling out, and a short circuit may occur between the wiring pattern 2 and the island. Although it seems possible to deal with this problem by reducing the amount of conductive paste, there will be areas where the adhesion is insufficient, resulting in inconveniences such as the inability to perform bonding on the insulated circuit board. Therefore, conventionally, the insulated circuit board 1 and the island have been bonded using the configuration shown below.

That is, first, the insulated circuit board 1 and the island 6 are bonded together using an insulating paste 7, and the predetermined wiring pattern 2 and the island 6 are connected using a bonding wire 8 (see FIG. 7). ). Second, an insulated circuit board 1 having through holes 3 is used, a conductive paste 9 is used directly under the through holes 3, and an insulating paste 7 is used near the cut surface of the insulated circuit board 1. be(

However, when using the former configuration, a bonding area on the island 6 is essential. This region needs to have an area of at least 0.4 mm2. Further, when the frame is designed to have a minimum area, bonding may not be possible due to the insulating paste 7 protruding, which causes a decrease in yield. Even if the bonding is completed, problems such as wire ovens may occur due to the weak connection strength, and there is a high probability that the reliability will be lowered and the product will be defective in the market.

(Problems to be Solved by the Invention) As described above, conventionally, in order to prevent short circuits between the wiring pattern and the island, it was not possible to use only a conductive paste for bonding the insulated circuit board. On the other hand, it is also possible to use an insulating paste to bond the insulated circuit board and to connect a predetermined wiring pattern to the island using a bonding wire, but there are problems with the bonding area, reliability, etc. On the other hand, it is also possible to use an insulated circuit board with through holes and use two types of pastes, but there is a problem with the application accuracy.

This is the case where it is glued onto 2. That is, the bottom surface of the insulated circuit board 21 is covered with the island 22 by the anisotropic conductive paste 23.
is glued to. A wiring pattern 24 is formed on the upper surface of the insulated circuit board 21. In addition, the insulated circuit board 2
1 is provided with a through hole 25. The wiring pattern 24 is connected to the anisotropic conductive paste 23 via this through hole 25. Here, when bonding the insulated circuit board 21 to the island 22, as shown in FIG. The electrically conductive fillers 30 in the insulating circuit board 23 contact each other mainly in a direction (hereinafter referred to as a vertical direction) that crosses the lower surface of the insulated circuit board 21 . As a result, the anisotropic conductive paste 23 becomes conductive only between the insulated circuit board 21 and the island 22 and only in the direction crossing the lower surface of the insulated circuit board. Therefore, the other surroundings of the insulated circuit board 21 (near the cut surface) and the direction parallel to the lower surface of the insulated circuit board (hereinafter referred to as the lateral direction) have insulation properties. That is, the island 22 and the predetermined wiring pattern 24 are electrically connected by the anisotropic conductive paste 23 via the through hole 25, and the other wiring pattern 2 exposed on the cut surface around the insulated circuit board 21
4 and the island 22 maintain insulation.

According to such a configuration, the insulating circuit board 21 is provided with a through hole 25, and the island 22 and the predetermined wiring pattern 24 are electrically connected via the through hole 25. Therefore, it is possible to bond the insulated circuit board 21 and the island 22 with one type of paste, and while maintaining the conductivity between the predetermined wiring pattern 24 and the island 22, it is possible to bond the insulated circuit board 21 and the island 22, while maintaining the conductivity between the predetermined wiring pattern 24 and the island 22. It becomes possible to maintain insulation between the island 22 and other wiring patterns 24 that are connected to each other. Further, there is no need to provide a bonding area on the island 22, and bonding defects due to paste protrusion can be reduced. Furthermore, since the connection area is larger than that of a bonding wire, it is advantageous in terms of electrical characteristics.

In this embodiment, one insulated circuit board 21 is bonded onto a plurality of islands 22a and 22b. Due to system characteristics, it may be necessary to divide the island in order to prevent malfunctions due to noise from other elements connected to GND (ground point). In such a case, by bonding the insulated circuit board 21 across the islands 22a and 22b using the anisotropic conductive paste 23, the wiring patterns 24a and 24b within the same insulated circuit board 21 can be connected, respectively. It is possible to have a separate GND. Note that, as described above, the anisotropic conductive paste 23 conducts electricity only in the vertical direction and does not conduct electricity in the horizontal direction, so the wiring patterns 25a and 25b are insulated.
