[0004] Furthermore, the present invention relates to a current converter having at least one such semiconductor module.
[0005] Furthermore, the present invention relates to a computer program product comprising instructions which, when executed on a computer, cause the computer to simulate the behavior of such a device, in particular the mechanical and / or electrical behavior. Background Art
[0006] Such a device can be part of a semiconductor module typically used in a current converter. A current converter can be understood, for example, as a rectifier, an inverter, a converter or a DC voltage converter. The device can be part of a housing for at least one semiconductor component. Such a housing typically includes a plurality of housing parts, such as one or more housing frame parts, a housing substrate (also referred to as a base plate) and a housing cover. The individual housing parts are usually bonded to each other such that at least one semiconductor component, such as an integrated circuit, is completely enclosed by the housing inside the housing. The semiconductor components used in such a semiconductor module can include, but are not limited to, transistors, diodes, triacs or thyristors. For example, a transistor is formed as an insulated gate bipolar transistor (IGBT), a field effect transistor or a bipolar transistor. For electrical contact, electrical contacts, i.e., so-called pins, which lead outwards from the inside of the housing, are usually provided.
[0007] The published document WO 2021 / 209186 A1 describes a semiconductor module having a housing, at least one semiconductor component, a first substrate and a second substrate. In order to provide a more compact semiconductor module compared to the prior art, it is proposed that at least the semiconductor component and the first substrate be arranged in the housing, wherein the semiconductor component is conductively connected to at least one pin, wherein at least one pin contacts the second substrate and is inseparably connected in the housing, and wherein the first substrate is force-fittedly connected in the housing via at least one pin.
[0008] In such a housing, it is possible to establish electrical connections, including but not limited to, by wire bonding. Here, a common method is ultrasonic wire bonding, in which the bonding wire is welded to the bottom surface by pressure and ultrasonic vibration. When performing ultrasonic wire bonding on the bonding surface of the pin, the vibration generated during the bonding process can excite unwanted vibrations, such as through resonance, so that the welded connection between the bonding wire and the bonding surface of the pin cannot be established or cannot be established with the required quality. Summary of the Invention
[0009] Therefore, the object of the present invention is to provide a method for manufacturing a device having a base plate and a housing part for accommodating semiconductor elements, which is as simple and cost-effective as possible and enables reliable wiring.
[0010] According to the present invention, this object is achieved by a method for manufacturing a device having a base plate and a housing part for accommodating semiconductor elements, the housing part including: forming a first housing assembly, wherein at least one pin is at least partially cast into a first plastic frame, and a wiring surface is formed at the pin; inserting a second housing assembly having a damping material into the first housing assembly to form the housing part, wherein the damping material is in loose contact with a contact surface arranged on a side of the first housing assembly facing away from the wiring surface; connecting the housing part to the base plate, wherein the second housing assembly is in contact with, in particular directly in contact with, the base plate.
[0011] Furthermore, according to the present invention, this object is achieved by a device having a base plate and a housing part for accommodating semiconductor elements, wherein the housing part includes a first housing assembly and a second housing assembly, the first housing assembly having at least one pin, the pin being at least partially cast into a first plastic frame, a wiring surface being formed at the pin, the second housing assembly being inserted into the first housing assembly to form the housing part, the second housing assembly having a damping material, the damping material being in loose contact with a contact surface arranged on a side of the first housing assembly facing away from the wiring surface, and the housing part being connected to the base plate such that the second housing assembly is in contact with, in particular directly in contact with, the base plate.
[0012] Furthermore, according to the present invention, this object is achieved by a semiconductor module having at least one such device.
[0013] Furthermore, according to the present invention, this object is achieved by a current converter having at least one such semiconductor module.
[0014] Furthermore, according to the present invention, this object is achieved by a computer program product including instructions that, when the program is executed on a computer, cause the computer to simulate the behavior, in particular the mechanical and / or electrical behavior, of such a device.
[0015] The advantages and preferred design solutions listed below for the method can be transferred, in terms of meaning, to the device, semiconductor module, current converter, and computer program product.
[0016] The present invention is based on the following considerations: reliable wiring of the wiring surface of at least one pin is achieved by attenuating vibrations occurring during the wiring process by means of a vibration damping material, wherein the pin is at least partially cast into the first plastic frame of the first housing component. Here, the housing component is made of at least two parts, namely the first housing component and the second housing component, wherein the first housing component includes the first plastic frame, and at least one pin having a wiring surface is cast into the first plastic frame. For example, the first plastic frame is formed annularly, especially rectangularly annularly, and is configured to completely surround the semiconductor element. In a further, especially subsequent step, the second housing component with the vibration damping material is inserted into the first housing component to form the housing component. The vibration damping material can include, for example, silicone resin. The insertion can include the connection of the housing components, for example, by pressing. The vibration damping material of the second housing component contacts the contact surface of the first housing component loosely, and the contact surface is arranged on the side facing away from the wiring surface. In this context, contacting loosely can be understood as: the vibration damping material contacts the contact surface detachably, that is, for example, without a material-fit connection, that is, for example, without an adhesive connection. Loose contact can include pressing the vibration damping material. For example, the vibration damping material containing silicone resin contacts the contact surface in a cured state. In a further, especially subsequent step, the housing component is connected to the bottom plate, wherein the second housing component contacts the bottom plate, especially directly. By loosely contacting the vibration damping material with the contact surface arranged on the side facing away from the wiring surface, an improvement in vibration damping during the wiring process is achieved. In addition, due to the reduction in the number of process steps, the manufacturing process is simplified by the loose contact of the vibration damping material. For example, the time-consuming dispensing process and the subsequent drying process are eliminated. Therefore, the manufacturing process is simplified by the method, and costs are saved by reducing the number of process steps.
[0017] A computer program product including instructions can include a "digital twin", also known as a "digital twin" or can be formed as a digital twin, wherein when the program is executed by a computer, the instructions cause the computer to simulate the behavior of the described device, especially the mechanical and / or electrical behavior. For example, such a digital twin is shown in the published document US2017 / 0286572 Al. The disclosure of US 2017 / 0286572A1 is incorporated herein by reference. For example, a "digital twin" is a digital representation of components related to the manufacture and / or operation of a device.
[0018] Another embodiment provides that the damping material contacts the contact surface in a plane, in particular over the entire surface. By contacting the damping material in a plane, in particular over the entire surface, the vibrations occurring during the wiring process are optimally damped.
[0019] Another embodiment provides that at least one semiconductor element is arranged on the base plate, wherein, after connecting the housing part to the base plate, the wiring surface of the pin is wire-connected to the semiconductor element, and wherein the vibrations occurring during the wiring of the wiring surface are at least partially damped by the damping material. The wiring element can include but is not limited to a bonding wire or a bonding tape, and the bonding wire or the bonding tape is welded, in particular, by ultrasonic wire bonding. The vibrations of such a bonding connection are optimally damped by the damping material.
[0020] Another embodiment provides that at least one semiconductor element is electrically insulated and thermally connected to the base plate via a substrate before connecting the housing part to the base plate. The substrate can include but is not limited to being formed as a DGB (direct copper bonding) substrate. For example, the semiconductor element is formed as a vertical transistor, in particular as an IGBT or a vertical SiC-MOSFET, and this connection via the substrate saves space and is cost-effective. For example, the wiring surface of at least one pin is connected to the substrate, and the substrate is connected to the semiconductor element via another wiring element. Alternatively, the wiring surface of at least one pin can be directly wire-connected to the semiconductor element. A manufacturing process with a small number of process steps is achieved through the sequence of process steps.
[0021] Another embodiment provides that the connection of the housing part is carried out by a material-fit, in particular adhesive, connection of the first housing assembly and / or the second housing assembly to the base plate. For example, the first plastic frame or the second plastic frame of the housing part is adhesively connected to the base plate. In particular, the adhesive connection between the housing part and the base plate cures under tension. This material-fit connection has a minimal impact on the damping effect of the damping material.
[0022] Another embodiment provides that the second housing assembly includes a second plastic frame, and the damping material is applied, in particular applied circumferentially, on the second plastic frame before insertion. For example, the second plastic frame is formed annularly, in particular rectangularly annularly, and is configured to completely surround the semiconductor element. In particular, the circumferential application of the damping material ensures the best possible damping. A stable structure and a simple connection are achieved through the second plastic frame when the damping is sufficient.
[0023] Another embodiment provides that a force-fit connection is established between the housing assemblies when inserting the second housing assembly. In particular, a force-fit connection is established between the first plastic frame of the first housing assembly and the second plastic frame of the second housing assembly. Such a force-fit connection can be established, for example, simply and cost-effectively. Such a force-fit connection includes but is not limited to being able to simplify the subsequent pasting process.
[0024] Another embodiment provides that the damping material is formed as a particularly circumferential silicone resin layer, which is applied to the second shaping frame by screen printing or by a dispenser and then cured. When the second housing assembly is inserted, the cured silicone resin layer contacts the contact surface particularly in a planar manner. Through this pre-application, the cured silicone resin layer can contact the contact surface loosely or relaxably, thereby improving the attenuation of vibrations occurring during the wiring process. In addition, the loose contact of the damping material simplifies the manufacturing process.
[0025] Another embodiment provides that the second housing assembly is implemented as a damping frame made of damping material. For example, the damping frame is implemented as an annular, particularly rectangular annular silicone resin frame or a rubber frame. By using such a damping frame, the manufacturing process is simplified.
[0026] Another embodiment provides that when the second housing assembly is inserted, a force-fitting connection is established between the first housing assembly and the damping frame. Such a force-fitting connection can be simply and cost-effectively manufactured by clamping, for example. In addition, the force-fitting connection further simplifies the manufacturing process.
