Description

[Technical field]

[0001] The present disclosure relates to a semiconductor power module for a semiconductor device and a corresponding semiconductor power device. The present disclosure further relates to a corresponding manufacturing method for the semiconductor power module. [Background technology]

[0002] Semiconductor power packages form a technology for low, medium and high voltage applications that are subject to mechanical stresses, for example due to fastening to coolers or during thermal cycling. There is therefore a risk of creating fissures or cracks in the module encapsulation, for example due to thermomechanical stresses. In this regard, it is generally a challenge to prevent damage. The document US Pat. No. 8,906,749 (B2) discloses a method for manufacturing a semiconductor device and a corresponding semiconductor comprising a carrier and at least one semiconductor chip. According to one embodiment, the chip of the semiconductor device is in contact with a fiber-reinforced encapsulation layer that completely covers the chip. Summary of the Invention [Means for solving the problem]

[0003] Embodiments of the present disclosure relate to stable semiconductor power modules exhibiting a reduced risk of damage. Further embodiments of the present disclosure relate to providing corresponding semiconductor devices and manufacturing methods for such power modules.

[0004] According to one embodiment, the semiconductor power module comprises a substrate layer forming a base plate and a molding coupled to the substrate layer, the molding comprising at least one fiber and / or mesh structure forming a localized reinforcement embedded in the molding.

[0005] By using the described configuration, a stable semiconductor power module with mechanically reinforced parts using fibers and / or meshes can be realized at low cost. The semiconductor power module therefore contributes to reducing the risk of damage, for example, at sensitive locations of narrow walls or thinned parts or parts exposed to increased stress. The semiconductor power module can also be called a semiconductor power package.

[0006] The substrate layer can be a single layer or can include a base plate that includes or has more substrates. The substrate layer can also be a lead frame that supports the molded body. The substrate layer can also be a part of the molded body that is integrally formed with the molded body in one piece. The term "embedded" can also mean or be interpreted as meaning that there is a fiber and / or mesh structure that is impregnated with the compound of the molded body or covered with the compound of the molded body. The fiber and / or mesh structure can also be embedded in the sense that it is completely enclosed in the molded body. Alternatively, the fiber and / or mesh structure can be partially embedded. Alternatively or additionally, the mold compound may initially include the fiber.

[0007] In the context of this disclosure, it is recognized that with respect to conventional packages, the package body is assembled, for example, with a rigid substrate or with a base plate having a substrate, to provide sufficient mechanical stability. Nevertheless, in terms of molded packages, the typical size of a conventional body is relatively small. Furthermore, conventional molded modules include standard molding compounds with a high degree of filler, for example, filled with 80-90% silica particles for tuning the thermal expansion coefficient and for desired dielectric behavior. Such a high filler content makes the molding compound weak in mechanical behavior.

[0008] The described reinforced semiconductor power module can be made to eliminate mechanical instability, making its application even possible in large power packages with sufficient and reliable stability, for example with edge lengths of 50 mm or more and up to 100 mm. For example, the described semiconductor power package can be made in a size of, for example, 100×140 mm for large substrate applications. 2 The semiconductor power package can be suitable even for body sizes of 100 mm to 150 mm. Such large sizes make the body of the power module even more sensitive to mechanical stresses, which arise for example when screwing the power module onto a cooler or by bending during thermal cycling. Thanks to one or more local reinforcements, each encapsulating a fiber and / or mesh structure embedded in the molding, the semiconductor power package can withstand the aforementioned stress effects even in the case of such large dimensions. Thus, cracks in the molding, especially at mechanically critical locations, can be prevented.

[0009] In the context of the present disclosure, it is further recognized that mechanically critical locations exist, on the one hand, near the terminal openings which realize weak points of the package design, and, on the other hand, for example, in areas next to screw attachments or above the chip. Thus, according to one embodiment of the semiconductor power package, the molded body includes an opening, a recess, a thinned area and / or a narrow wall structure, and at least one local reinforcement is formed adjacent to the opening, the recess and / or the narrow wall structure. By such configurations of reinforcement of mechanically critical locations, it is possible to achieve sufficient mechanical stability of any part of the molded body exposed to mechanical stress, for example, next to a screw connection.

[0010] The aforementioned thinned areas refer, for example, to walls, sides, top and / or bottom parts having a smaller wall thickness compared to the respective adjacent parts of the molding. Compared to the thicker parts of the molding, narrow-wall structures can also refer to relatively thin walls, for example at the edges of the molding or between two recesses, which may be parts of the molding that are exposed to increased stress due to the intended placement. Such thin areas therefore advantageously include respective reinforcements.

[0011] According to a further embodiment of the semiconductor power package, the molded body includes a first molding compound and a second molding compound different from the first molding compound. The first molding compound is configured to form a first molded body part without localized reinforcement, and the second molding compound is configured to form a second molded body part including at least one fiber and / or mesh structure and with localized reinforcement. Thus, a semiconductor power package including at least two different molding compounds is feasible to enable a mechanically stable and reliable structure.

[0012] The second molding compound can include glass fibers and / or carbon fibers. For example, the first and second molding compounds differ from each other in terms of their respective filler and / or resin materials. Furthermore, the first and second molding compounds and the corresponding first and second molded body parts can be formed to overlap each other at least partially in the lateral direction. Alternatively or additionally, some parts of different molding compounds can be arranged side by side.

[0013] Alternatively or additionally to the aforementioned reinforcing second molding compound, the molded body may include a separate reinforcement portion including at least one fiber and / or mesh structure forming a molded body portion with localized reinforcement. The separate reinforcement portion may include glass fiber and / or carbon fiber. According to an embodiment of the semiconductor power package, the separate reinforcement portion includes a metal mesh. Alternatively or additionally, the separate reinforcement portion includes a non-conductive mesh.

[0014] Furthermore, the semiconductor power package may further include an electronic unit, e.g., a chip, a processing unit and / or an integrated circuit, which is bonded to the substrate layer and is embedded in or covered by the local reinforcement. In terms of the electronic unit, it is also possible that the electronic unit is embedded in or bonded to the molding of the semiconductor power module without contacting the local reinforcement. The local reinforcement, which includes a fiber and / or mesh structure, may be implemented only in one or more regions of the molding in addition to the electronic unit. The at least one local reinforcement may be formed directly next to the electronic unit or at a distance from the electronic unit with respect to the lateral direction of the semiconductor power module. The local reinforcement may be formed, for example, in one or more regions that are not thinned or recessed but in which relatively strong mechanical stresses occur, for example, during assembly. Alternatively or additionally, the local reinforcement may be implemented in one or more regions in addition to the electronic unit where two molding compounds are used overlapping each other or where other thinner parts of the molding compound are formed, for example, above or below the terminals.

[0015] The described embodiments realize possible configurations of semiconductor power packages, including at least one localized increase in the mechanical stability of the molded body, each by fibers or by meshes or elements made of fibers. The molded body can realize a relatively large package body, for example formed by transfer molding. Reinforcement structures can be incorporated in particular based on the localized use of fiber-reinforced molding compounds and / or based on the implementation of meshes or fiber elements, each arranged in mechanically critical areas of the molded body.

[0016] In terms of the second molding compound for reinforcement, epoxy molding compounds containing a certain amount of fibers, such as glass or carbon fibers, can be used. The molding thus comprises two different molding compounds, the second molding compound being applied in mechanically critical areas, for example near threaded connections or in thin areas of the molding. Furthermore, the entire part of the molding may be realized by the fiber-reinforced second molding compound, or a layered stack of the fiber-reinforced second molding compound may be prepared under and / or on the first molding compound. The stack may be applied to a part of the molding or to the entire molding.

[0017] The choice of the first molding compound to be used for the other parts of the molded body can be made depending on the fulfillment of requirements that are important in those parts, such as thermomechanical behavior, molding compound adhesion, dielectric strength, and / or protection from moisture and / or toxic gases.

[0018] In terms of the implementation of separate mesh or fiber elements in mechanically critical areas, such components can be glued to the substrate layer or applied to a molding tool before the molding process for the preparation of the molded body is carried out. For example, a temporary adhesive material can be used for fixing in the molding tool. The mesh or fiber elements can be made of conductive or non-conductive wires or fibers. Such reinforcements can therefore be incorporated into the molded body by a molding process in which the elements are impregnated with a molding compound.

[0019] The configuration of large molded semiconductor power packages in which local mechanical reinforcement structures are implemented facilitates the realization of power modules, especially those having relatively large molded bodies. Thus, the business interests relate to the advantages of the corresponding semiconductor power modules, the described configuration of the semiconductor power packages enabling at least one or more of the following:

[0020] Larger molded semiconductor power modules can facilitate the application of larger substrates or larger total substrate areas, and therefore larger total chip areas. Thus, the current performance of the semiconductor power modules can be increased. Thus, customers have an economic benefit by needing fewer power modules for a given current.

[0021] Semiconductor power modules having relatively large molded bodies have the potential for greater thermal cycling reliability due to reduced thermal expansion mismatch between the mold compound and the substrate layers.

[0022] Resistance to moisture and toxic gases is greatly increased with respect to standard power modules which are filled with, for example, dielectric gel.

[0023] Due to the increased mechanical stability of the molding compound, the explosion-proof properties of the semiconductor power module can be increased as well.

[0024] The implementation of exclusively local reinforcing structures or the exclusively local use of fiber-reinforced molding compounds makes it possible advantageously to adapt the molding compounds used in other parts of the molding in accordance with local requirements.

[0025] According to one embodiment, a semiconductor device comprises an embodiment of the described semiconductor power package and electronics coupled to the semiconductor power package. The semiconductor power device may also comprise a heat sink coupled to a substrate layer of the semiconductor power package for dissipating heat during operation. The electronics may include one or more chips or discrete devices attached to the substrate layer.

[0026] According to one embodiment, a method of manufacturing an embodiment of a semiconductor power package includes providing a substrate layer, providing at least one fiber and / or mesh structure, providing a pumpable material, and molding the provided material onto the substrate layer such that a molded body is formed having at least one fiber and / or mesh structure embedded in the molded body forming a localized reinforcement portion.

[0027] The step of providing at least one fiber and / or mesh structure may include providing a first molding compound and providing a second molding compound different from the first molding compound, the first molding compound configured to form a first molded body portion having no localized reinforcement, and the second molding compound configured to form a second molded body portion including the at least one fiber and / or mesh structure and having localized reinforcement.

[0028] Alternatively or additionally, the steps of providing at least one fiber and / or mesh structure and shaping the provided material may include providing a separate reinforcement portion comprising at least one fiber and / or mesh structure, positioning the reinforcement portion against the substrate layer or placing the reinforcement portion in a molding tool using a temporary adhesive material, and molding the provided material onto the substrate layer such that a molded body is formed with the reinforcement portion forming an embedded or covered localized reinforcement portion.

[0029] Because the described semiconductor device and the described manufacturing method include or relate to manufacturing an embodiment of a semiconductor power package, the described features and characteristics of the semiconductor power package are also disclosed with respect to the semiconductor device and manufacturing method, and vice versa.

[0030] Exemplary embodiments of semiconductor power packages are described below with the aid of schematic diagrams and reference numbers. [Brief description of the drawings]

[0031] [Figure 1] 1 illustrates an embodiment of a semiconductor power package in a perspective view. [Diagram 2] 1 illustrates an embodiment of a semiconductor power package in side view. [Diagram 3] 1 illustrates an embodiment of a semiconductor power package in side view. [Figure 4] 1 shows a flow chart for a method of manufacturing one embodiment of a semiconductor power package. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The accompanying drawings are included to provide further understanding. It should be understood that the embodiments shown in the figures are exemplary representations and are not necessarily drawn to scale. The same reference numbers indicate elements or components having the same function. Insofar as elements or components correspond to one another in terms of their function in the various figures, their description will not be repeated for each of the following figures. For clarity, elements may in some cases not be found with corresponding reference numbers in all figures.

[0033] FIG. 1 shows a perspective view of an embodiment of a semiconductor power package 10 comprising a substrate layer 11 and a shaped body bonded to the substrate layer 11. The shaped body has at least one fiber and / or mesh structure embedded in the shaped body forming a localized reinforcement. According to FIG. 1, the semiconductor power package 10 extends in lateral directions B and C defining a main extension plane, whereas a stacking direction A is approximately perpendicular to the lateral directions B and C (see also FIGS. 2 and 3). A shaped body comprising a first shaped body part 12 and a second shaped body part 13 is formed on the substrate layer 11 with respect to the stacking direction A.

[0034] The term "embedded" can be interpreted as having fibers and / or mesh structures that are impregnated or covered with the compound of the molding. The fibers and / or mesh structures can also be embedded in the sense that they are completely enclosed within the molding. Alternatively, the fibers and / or mesh structures can be partially embedded. Alternatively or additionally, the corresponding molding compound may initially contain the fibers.

[0035] In Fig. 1, the molding of the semiconductor power package 10 has a first molding part 12 and a second molding part 13. According to the embodiment shown in Fig. 1, there are two first molding parts 12 and three second molding parts 13. The first molding parts 12 and the second molding parts 13 differ in that the second molding parts 13 each include a fiber and / or mesh structure that forms the respective part of the molding that has reinforcement. Thus, the first molding parts 12 form the respective part of the molding that does not have fiber and / or mesh structure reinforcement.

[0036] The second molded body parts 13 for reinforcement are associated with mechanically critical parts, for example near the screw holes 15, the recesses 16, the narrow wall structures 17, and / or with thinned parts or thinned areas 18 of the molded body, for example on the top surface or on the chip or next to the screw holes. The thinned areas 18 denote walls, upper and / or lower parts having a smaller wall thickness compared to the respective adjacent parts of the molded body. The illustrated semiconductor power package 10 thus comprises first, second, third and fourth reinforced areas A1-A4. The further recesses 16 may not belong to the reinforced areas, for example depending on the intended application of the semiconductor power package 10, since they do not represent mechanically critical positions.

[0037] 2 and 3 show a further embodiment of the semiconductor power package 10 in respective side views. FIG. 2 shows the second shaped body part 13 forming a continuous layer on the first shaped body part 12, which is assembled as a continuous layer on the substrate layer 11 with respect to the stacking direction A. Thus, the first shaped body part 12 is arranged between the second shaped body part 13 and the substrate layer 11. In other words, the second shaped body part 13 covers the first shaped body part 12. The second shaped body part 13 can be formed, for example, by a molding compound with glass fibers and / or carbon fibers. The first shaped body part 12 is formed by a molding compound without fibers, which can be filled, for example, with silicon dioxide particles. The substrate layer 11 forms the base plate of the semiconductor power package 10.

[0038] FIG. 3 shows an alternative arrangement of the first and second molded body parts 12 and 13, where one second molded body part 13 covers the electronic unit 14, thus achieving enhanced protection when the molded body has local thinner sections. The electronic unit 14 is firmly embedded between the reinforcing second molded body part 13 and the substrate layer 11. Furthermore, one or more local sections of the molded body can be completely prepared by the second molding compound. One or more sections of the first and / or second molded body parts 12 and / or 13 can be arranged side by side with respect to the transverse directions B and / or C and / or partially or completely overlapping each other with respect to the stacking direction A, respectively.

[0039] One embodiment of the semiconductor power package 10 may be manufactured according to a flow chart as shown in FIG.

[0040] In step S1, a substrate layer 11 is provided. In step S2, at least one textile and / or mesh structure 11 is provided.

[0041] In step S3, one or more pumpable substances are provided which realize the respective liquid feedstocks which will form the subsequent shaped bodies, in this respect the pumpable substances providing the feedstocks which enable the corresponding shaping process.

[0042] In step S4, the provided material is molded onto the substrate layer 11 such that a molded body is formed having at least one fiber and / or mesh structure embedded therein forming localized reinforcements. The molding can be carried out, for example, by transfer molding and / or compression molding and / or injection molding.

[0043] The step S2 of providing at least one fiber and / or mesh structure may include providing a first molding compound and providing a second molding compound different from the first molding compound, the first molding compound being configured to form a respective first molded body portion 12 having no localized reinforcement, and the second molding compound being configured to form a respective second molded body portion 13 including at least one fiber and / or mesh structure and having localized reinforcement.

[0044] Therefore, step S3 may include two molding processes: molding a first molding compound onto the substrate layer 11 and molding a second molding compound onto the substrate layer 11 and / or onto the first molding compound. The molding of the first molding compound and the second molding compound may be performed simultaneously or sequentially.

[0045] Alternatively or additionally, step S2 of providing at least one fiber and / or mesh structure and step S4 of molding the provided material may comprise providing a separate reinforcement portion comprising at least one fiber and / or mesh structure, positioning the reinforcement portion on the substrate layer 11, and molding the provided material on the substrate layer 11 such that a molded body is formed having the reinforcement portion embedded by encapsulation or coating, thus forming a local reinforcement portion with respect to the second molded body portion 13.

[0046] The described embodiment of the semiconductor power package 10 includes a localized increase in mechanical stability and allows the production of relatively large transfer molded package bodies by fibers or elements based on meshes and / or fibers. The reinforcement of the molded body may be applied in particular to locations where the corresponding molding compound is exposed to high stresses due to being next to screw holes 15, or where some parts of the package body have only a small cross section or are relatively thin due to being between openings or recesses 16 for terminal attachment or on electronic units 14 or other semiconductor components. Nevertheless, there may be other areas in the molded body where reinforcement may be applied. FIG. 1 shows a possible arrangement of a large molded semiconductor power package 10 that may have an edge length of up to 100 mm or more. However, the described formation of localized reinforcement is also suitable for any type of semiconductor power module with molded body, but also for smaller sizes, for example with an edge length of more than 50 mm or between 30 mm and 80 mm.

[0047] The reinforcing structure can be implemented in the molded body based on the local use of a fiber-reinforced second molding compound. For example, the second molding compound is an epoxy molding compound containing a certain amount of fibers, such as glass or carbon fibers. The molded body of the semiconductor power package 10 thus comprises two different molding compounds, the second molding compound for reinforcement being used in the mechanically important parts. The selection of the first molding compound used in the other parts of the molded body can be made depending on the achievement of requirements that are important in the other parts of the semiconductor power package 10, for example, to establish a certain thermomechanical behavior, adhesion of the molding compound, dielectric strength, and / or protection from moisture and toxic gases.

[0048] The reinforcing structure can also be implemented in the moulded body based on the implementation of separate reinforcing parts comprising meshes and / or fibre elements to reinforce the mechanically critical areas of the moulded body. Such meshes and / or fibre elements can be glued, for example by using a temporary adhesive material, to the substrate layer 11 which is brought to the moulding tool before the moulding process for the preparation of the moulded body is carried out.

[0049] The proposed reinforcing structure and the corresponding second molded body part 13 can be implemented on the one hand in a very localized location such as a single relatively thin wall, or on a thinner part above the chip as shown in FIG. 3, or next to the threaded part. On the other hand, larger parts of the molded body can also be realized with the reinforcing structure as shown in FIG. 2. The realization of a molded body containing two different molding compounds can be realized by two subsequent molding processes or by a single molding process followed by the injection of two different first and second molding compounds. For example, the use of a molding compound containing fibers may be well suited to prepare larger module parts such as the area of ​​some openings or recesses 16 in the center of the semiconductor power package shown in FIG. 1. In other cases, a layered stack of a fiber-reinforced second molding compound and another first molding compound may be prepared locally or over the entire area of ​​the power package. The described order may also be reversed, for example, the molding of the second molding compound for reinforcement first and then the molding of the first molding compound.

[0050] When using mesh elements that are attached to the substrate layer 11 during processing or incorporated into the molding tool, only one homogenous molding compound can be used for the molded body. A corresponding semiconductor power module can include three different components using the mesh element(s), a second molding compound with fibers, and a first molding compound without fibers.

[0051] Where a fiber-reinforced second molding compound is used locally, on the other hand, a completely different molding compound can be used and the molding compound used for the molding or other parts of the semiconductor power package 10 can be adapted to other specific requirements, such as, for example, adhesion, moisture absorption or fracture strength. Alternatively or additionally, the semiconductor power package 10 can meet such requirements and / or further requirements by a different base material of the substrate layer 11 and / or adders or coatings to the substrate layer 11.

[0052] For example, the semiconductor power package 10 implements a transfer molded power device in which one or more localized portions of the molded body are mechanically reinforced by the use of the aforementioned fibers and / or mesh structures. The localized reinforcement can include any type of fiber, such as fiberglass or carbon fiber or any other type of fiber. Additionally or alternatively, if a mesh structure is used, the mesh can be implemented as a separate modular part and can include a metal mesh, a mesh made of a non-conductive material, or another material.

[0053] The arrangement of two different molding compounds can be done, for example, locally with layered lamination of lower and upper molding compounds, covering the entire size of the molded body. The first and second molding compounds can have the same basic molding compound, differing only in filler type (e.g., fibers and / or particles). The two molding compounds can also differ in their basic resin material, components and / or fillers. Lateral arrangement of parts of different molding compounds is also possible.

[0054] With regard to material properties, the described embodiments relate to a molded semiconductor power package. However, it is pointed out that the molding and / or the substrate layer 11 can alternatively be made of a polymeric material, which generally forms the polymer body and / or the substrate layer 11. According to the described embodiments, the semiconductor power package 10 can include a thermosetting material and the molding comprises a molding compound. Thus, the semiconductor power package 10, the substrate layer 11 and / or the molding can be made of an electrically insulating material, a thermosetting material or a thermoplastic material. The substrate layer 11 and the molding can be realized as separate components or can be manufactured to integrally form one piece.

[0055] The thermosetting material may be made, for example, based on epoxy resin. The thermoplastic material may, for example, include one or more materials from the group of polyetherimide (PEI), polyethersulfone (PES), polyphenylene sulfide (PPS) or polyamideimide (PAI). The thermoplastic material melts by applying pressure and heat during molding or lamination and (reversibly) solidifies upon cooling and pressure release. The molding, the substrate layer 11, or even the electrical insulating material of the semiconductor power package 10 as a whole may form an encapsulation that may include or be made of a polymer material. The electrical insulating material may include at least one of filled or unfilled molding materials, filled or unfilled thermoplastic materials, filled or unfilled thermosetting materials, filled or unfilled laminates, fiber reinforced laminates, fiber reinforced polymer laminates, and fiber reinforced polymer laminates with filler particles.

[0056] 1-4 above represent exemplary embodiments of the improved semiconductor power package 10 and corresponding manufacturing methods, and thus are not intended to be exhaustive of all embodiments. Actual arrangements and methods may differ from the embodiments shown, for example, for the semiconductor power package. [Explanation of symbols]
