Definitions
- the technology disclosed in this specification relates to a semiconductor module.
- the semiconductor device When the semiconductor device generates heat, the semiconductor device and its peripheral members (solder, wiring, etc.) thermally expand. Stress is applied to the semiconductor device due to the difference in coefficient of thermal expansion of each member. Such stress shortens the lifetime of the semiconductor device and the semiconductor module.
- Patent Document 1 discloses a semiconductor module in which a semiconductor device and each electrode are stacked and the semiconductor device and each electrode are connected by pressurizing them. Has been. However, in this semiconductor module, the first electrode is disposed so as to extend downward from the semiconductor device, and the second electrode is disposed so as to extend upward from the semiconductor device. Thus, when the 1st electrode and the 2nd electrode are separated, the problem that the inductance between the 1st electrode and the 2nd electrode will become large arises. Therefore, the present specification provides a semiconductor module in which a semiconductor device and a conductive member are connected by pressurization and an inductance between the conductive members is small.
- the semiconductor module disclosed in this specification includes a semiconductor device, a first conductive member, a second conductive member, a cylindrical body, and a cover.
- the semiconductor device includes a semiconductor substrate, a first electrode formed on one surface of the semiconductor substrate, and a second electrode formed on the surface of the semiconductor substrate opposite to the one surface.
- the first conductive member is in contact with the first electrode.
- the second conductive member is in contact with the second electrode.
- the cylinder surrounds the semiconductor device, is fixed to the first conductive member, and has a first thread groove on the outer peripheral surface or the inner peripheral surface.
- the cover is formed with a second thread groove, and is fixed to the cylinder body by engaging the second thread groove with the first thread groove.
- the semiconductor device and the second conductive member are fixed by being sandwiched between the first conductive member and the cover.
- the second conductive member has an extending portion that passes through the outer peripheral wall of the cylindrical body that is closer to the first conductive member than the cover and is drawn out from the inner side of the cylindrical body.
- the extending portion of the second conductive member passes through the outer peripheral wall of the cylinder and is drawn out from the inside of the cylinder.
- an extension part can be arranged along the 1st conductive member in the outside of a cylinder.
- the inductance between the first conductive member and the second conductive member is small.
- the extension part has penetrated the outer peripheral wall of the cylinder which exists in the 1st electroconductive member side rather than a cover. That is, the extension part penetrates the outer peripheral wall of the cylinder without penetrating the cover. For this reason, it is possible to rotate the cover and attach it to the cylinder (that is, engage the second thread groove with the first thread groove). For this reason, this semiconductor module can be easily assembled.
- a third electrode may be further formed on the one surface of the semiconductor substrate.
- the semiconductor module is in contact with the third electrode, passes through the outer peripheral wall of the cylinder existing on the first conductive member side of the cover, and is drawn out from the inside of the cylinder to the outside. It is preferable to further have a member.
- the wiring (for example, the second conductive member and the third conductive member) to the semiconductor device passes through the outer peripheral wall of the cylindrical body and is drawn to the outside of the cylindrical body. 1 It is not necessary to provide a wiring drawing structure on the conductive member and the cover. Therefore, a semiconductor device can be suitably cooled by connecting a cooler to the first conductive member and the cover. Therefore, in any one of the semiconductor modules described above, the first cooler is connected to the surface of the first conductive member opposite to the semiconductor device, and the second cooler is connected to the surface of the cover opposite to the semiconductor device. A cooler is preferably connected.
- an insulating member is disposed between the third conductive member and the first conductive member, and the third conductive member is fixed by being sandwiched between the third electrode and the insulating member. It is preferable that

- Each pin 90 is insulated from the case 40 by an insulator 92.
- the bus bar 30 is composed of a bent metal plate.

- the insulating plate 80 is placed on the first portion 30 a of the bus bar 30.
- the cover 50 is made of metal. An insulating coating is applied to the outer surface of the cover 50.
- the cover 50 includes a cylindrical side wall portion 50b and a flat plate portion 50a that closes one end of the center hole of the side wall portion 50b. That is, the cover 50 has a cup shape.
- a screw groove 50c is formed on the inner peripheral surface of the side wall 50b. The screw groove 50 c of the cover 50 is engaged with the screw groove 40 c of the case 40. That is, the cover 50 is fastened to the case 40 using the screw grooves 40c and 50c.
- the lower surface of the flat plate portion 50 a of the cover 50 is in contact with the insulating plate 80.
- the laminate composed of the metal plate 84, the semiconductor device 20, the metal plate 82, the first portion 30 a of the bus bar 30, and the insulating plate 80 is sandwiched between the flat plate portion 50 a of the cover 50 and the electrode plate 40 a of the case 40.
- the cover 50 is fastened to the case 40 with a high torque. Therefore, the laminate is pressurized by the flat plate portion 50a and the electrode plate 40a. With this pressure, each member constituting the laminate is fixed to the cover 50 and the case 40.
- the contact portion between the electrode plate 40a of the case 40 and the metal plate 84, the contact portion between the metal plate 84 and the source electrode 26 of the semiconductor device 20, the contact portion between the drain electrode 22 of the semiconductor device 20 and the metal plate 82, and The contact portion between the metal plate 82 and the first portion 30a of the bus bar 30 is not joined by a brazing material or the like. Therefore, when the cover 50 is removed from the case 40, the members of the laminate can be separated from each other.
- An insulating sheet 70 is fixed to the upper surface of the flat plate portion 50a of the cover 50.
- a cooler 72 is fixed to the upper surface of the insulating sheet 70.
- the cooler 72 is a liquid circulation type cooler. Note that grease is applied to a contact portion between the cover 50 and the insulating sheet 70 and a contact portion between the insulating sheet 70 and the cooler 72. Thereby, the thermal resistance between the cooler 72 and the cover 50 is reduced.
- An insulating sheet 60 is fixed to the lower surface of the electrode plate 40 a of the case 40.
- a cooler 62 is fixed to the lower surface of the insulating sheet 60. The cooler 62 is a liquid circulation type cooler.
- the wiring for the source electrode 26 located on the lower surface side of the semiconductor substrate 24 is configured by the electrode plate 40 a of the case 40.
- a wiring for the drain electrode 22 located on the upper surface side of the semiconductor substrate 24 is constituted by a bus bar 30.
- the bus bar 30 passes through the outer peripheral wall of the cylindrical body 40b and is drawn to the outside of the cylindrical body 40b.
- the extended portion 40e of the electrode plate 40a and the third portion 30c of the bus bar 30 are close to each other and are arranged substantially in parallel. Therefore, the inductance between them is reduced as compared with the conventional semiconductor module. That is, in the semiconductor module 10, the inductance between the wiring for the source electrode 26 and the wiring for the drain electrode 22 is reduced.
- the third portion 30c of the bus bar 30 is disposed near the extending portion 40e of the electrode plate 40a, external wiring for these can be easily installed. That is, if the wiring member for the drain electrode 22 is drawn to the upper side of the semiconductor module 10, the external wiring for the drain electrode 22 must be connected at a position away from the electrode plate 40a. On the other hand, in the semiconductor module 10 of the present embodiment, the third portion 30c is disposed near the extending portion 40e, so that external wiring for these can be easily installed.
- the pin 90 which is a wiring to the gate electrode 28 is also drawn out to the outside of the cylinder 40b through the outer peripheral wall of the cylinder 40b. That is, all the wirings except for the wiring constituted by the electrode plate 40a penetrate the outer peripheral wall of the cylindrical body 40b on the electrode plate 40a side with respect to the cover 50 and are drawn out from the inner side of the cylindrical body 40b. For this reason, the electrode plate 40 a and the cover 50 are not formed with a structure for drawing the wiring from the inside of the case 40 and the cover 50 to the outside. For this reason, it is realized that the lower surface of the electrode plate 40a and the upper surface of the cover 50 have a flat shape.
- the cooler 62 is suitably connected to the electrode plate 40a. Therefore, the semiconductor device 20 can be efficiently cooled by the cooler 62. Further, since the upper surface of the cover 50 is flat, the cooler 72 is suitably connected to the cover 50. Therefore, the semiconductor device 20 can be efficiently cooled by the cooler 72. That is, according to the semiconductor module 10, the semiconductor device 20 can be efficiently cooled from both sides.
- the semiconductor device 20 is fixed by pressure, and the semiconductor device 20 and the metal plates 82 and 84 are not joined by brazing or the like. Therefore, when the semiconductor device 20 and the metal plates 82 and 84 are thermally expanded due to heat generation of the semiconductor device 20, it is difficult to apply stress to the semiconductor device 20. Therefore, this semiconductor module 10 has a long life.
- a method for manufacturing the semiconductor module 10 will be described.
- a component in which the insulator 92 and the three pins 90 are integrated is prepared, and each pin 90 of the component is joined to each gate electrode 28 of the semiconductor device 20.

- the insulating plate 80 is placed on the first portion 30 a of the bus bar 30.
- the cover 50 is fixed to the case 40 by engaging the screw groove 50 c of the cover 50 with the screw groove 40 c of the case 40. When the cover 50 is moved downward by rotating the cover 50 about its central axis, the flat plate portion 50 a of the cover 50 contacts the insulating plate 80.
- the flat plate portion 50a of the cover 50 pressurizes the insulating plate 80 downward. That is, a laminated body sandwiched between the flat plate portion 50a of the cover 50 and the electrode plate 40a of the case 40 (that is, the metal plate 84, the semiconductor device 20, the metal plate 82, the first portion 30a of the bus bar 30, and the insulating plate 80). ) Is pressed in the stacking direction. Thereby, each member of the laminated body is fixed to the case 40 and the cover 50.
- the metal plate 84 is softer than the adjacent source electrode 26 and the electrode plate 40a of the case 40. For this reason, when the laminate is pressurized, the upper surface of the metal plate 84 is plastically deformed in accordance with the surface shape of the source electrode 26, and the metal plate 84 is in close contact with the source electrode 26. Similarly, when the laminate is pressurized, the lower surface of the metal plate 84 is plastically deformed in accordance with the surface shape of the electrode plate 40a, and the metal plate 84 is in close contact with the electrode plate 40a. Thereby, the source electrode 26 and the electrode plate 40a are reliably electrically connected.
- the metal plate 82 is softer than the adjacent drain electrode 22 and the bus bar 30. For this reason, when the laminate is pressurized, the lower surface of the metal plate 82 is plastically deformed in accordance with the surface shape of the drain electrode 22, and the metal plate 82 is in close contact with the drain electrode 22. Similarly, when the laminate is pressed, the upper surface of the metal plate 82 is plastically deformed in accordance with the surface shape of the bus bar 30, and the metal plate 82 is in close contact with the bus bar 30. Thereby, the drain electrode 22 and the bus bar 30 are reliably electrically connected.
- the cooler 72 is attached to the cover 50 via the insulating sheet 70.
- the cooler 62 is attached to the electrode plate 40 a via the insulating sheet 60. Thereby, the semiconductor module 10 shown in FIG. 1 is completed.
- the bus bar 30 and the pin 90 which are wirings for the semiconductor device 20, pass through only the cylindrical body 40 b and do not pass through the cover 50. Therefore, the cover 50 can be freely rotated during assembly. Therefore, the cover 50 can be attached to the case 40 by engaging the screw groove 40c and the screw groove 50c. Further, the laminated body can be pressed and fixed by this screw structure. Therefore, the semiconductor module 10 can be easily assembled.

- the same reference numerals as those of the first embodiment are assigned to members corresponding to the respective members constituting the semiconductor module 10 of the first embodiment.
- each pin 90 is not bonded to the gate electrode 28 but is only in contact therewith. Further, in the semiconductor module 100 of the second embodiment, an insulating block 88 is installed on the upper surface of the electrode plate 40 a at a position facing the gate electrode 28. The pin 90 is sandwiched and fixed between the insulating block 88 and the gate electrode 28. As a result, the pin 90 is electrically connected to the gate electrode 28.
- the semiconductor module 100 of the second embodiment First, the case 40 is prepared, and the metal plate 84 and the insulating block 88 are placed on the electrode plate 40a in the cylindrical body 40b. Next, a component in which the insulator 92 and the three pins 90 are integrated is installed. At this time, this component is inserted into the through hole 40f, and the inner end portion of the cylindrical body 40b of each pin 90 is placed on the insulating block 88. Next, the semiconductor device 20 is placed on the metal plate 84. At this time, the source electrode 26 is brought into contact with the metal plate 84, and each gate electrode 28 is brought into contact with a portion of each pin 90 on the insulating block 88.
- the metal plate 82, the bus bar 30, and the insulating plate 80 are installed, and then the cover 50 is fixed to the case 40.
- the cover 50 is rotated to pressurize the stacked body, the pressure is also applied to the pin 90 sandwiched between the gate electrode 28 and the insulating block 88. With this pressure, the pin 90 is fixed to the gate electrode 28.
- the coolers 62 and 72 are attached in the same manner as in the first embodiment, whereby the semiconductor module 100 of the second embodiment is completed.

Therefore, stress on the semiconductor device 20 is reduced around the contact point between the pin 90 and the gate electrode 28. Thereby, the reliability of the semiconductor device 20 is further improved.
