Technical Field
The present disclosure relates generally to electronic devices, and more particularly to semiconductor devices and methods for manufacturing semiconductor devices.
Background
Existing semiconductor packages and methods for forming semiconductor packages suffer from drawbacks, such as excessive cost, reduced reliability, relatively low performance, or excessive package size. Additional limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such approaches with the present disclosure and through reference to the drawings.
Disclosure of Invention
The present description includes, among other features, structures and related methods relating to electronic devices having embedded modules and heat transfer or cooling structures. In some examples, an electronic device includes an embedded module having a module component attached to a module substrate. In some examples, the module substrate is coupled to the device terminals and the conductive substrate is coupled to an opposite side of the embedded module. In some examples, the device terminals may include a leadframe. In some examples, the conductive substrate may be thermally conductive. In some examples, the conductive substrate may be thermally and electrically conductive.
In some examples, an embedded module may include a pair of module substrates located on opposite sides of a module component (e.g., a power semiconductor component). In some examples, the pair of module substrates may be electrically coupled together. In some examples, the signal transmission structure may be attached to the embedded module. In other examples, the signal transmission structure may be attached to one or both conductive substrates. In some examples, the electronic device is enclosed within a package, with one or more features exposed from portions of the package. The structure and method of the present disclosure avoids the use of spacer structures, among other things, which has caused stacking tolerance problems in the past. Such stack-up tolerance issues have resulted in package non-planarity and component cracking issues.

A first device substrate is coupled to the first module substrate. A device terminal is coupled to the first module assembly, and a device encapsulant structure encapsulates the first embedded module, the first device substrate, and the device terminal. A portion of the first device substrate is exposed from the device encapsulant structure and a portion of the device terminal is exposed from the device encapsulant structure.
In an example, an electronic device includes a first embedded module including a first module substrate including a first conductive structure, a second module substrate including a second conductive structure, and a first module assembly interposed between the first module substrate and the second module substrate. The first module assembly includes a first assembly terminal coupled to the first conductive structure and a second assembly terminal coupled to the second conductive structure. A first device substrate is coupled to the first module substrate and includes a first outward conduction layer. A second device substrate is coupled to the second module substrate and includes a second outward conduction layer. A device terminal is coupled to the first module assembly, and a device encapsulant structure encapsulates the first embedded module, the first device substrate, the second device substrate, and the device terminal. The device terminals, the first outward conductive layer, and the second outward conductive layer are exposed from the device encapsulant structure.
In an example, a method of manufacturing an electronic device includes providing a first embedded module including a first module substrate including a first conductive structure, a second module substrate including a second conductive structure, and a first module assembly interposed between the first module substrate and the second module substrate. The first module assembly includes a first assembly terminal coupled to the first conductive structure and a second assembly terminal coupled to the second conductive structure. The method includes providing a first device substrate coupled to the first module substrate, the first device substrate including a first outward conduction layer. The method includes providing a second device substrate coupled to the second module substrate, the second device substrate including a second outward conduction layer. The method couples a device terminal to the module assembly. The method includes providing a device encapsulant structure that encapsulates the first embedded module, the first device substrate, the second device substrate, and the device terminals. The device terminals, the first outward conductive layer, and the second outward conductive layer are exposed from the device encapsulant structure.

The following discussion provides various examples of semiconductor devices and methods of fabricating semiconductor devices. Such examples are not limiting, and the scope of the appended claims should not be limited to the specific examples disclosed. In the following discussion, the terms "example" and "e.g." are non-limiting.
The drawings show general construction and descriptions and details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the disclosure. Additionally, elements in the drawings figures are not necessarily drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of examples discussed in the present disclosure. Cross-hatching may be used to represent different portions of the drawings, but does not necessarily represent the same or different materials. Like numbers refer to like elements throughout the disclosure. Accordingly, elements having the same element numbers may be shown in the figures but need not be repeated here for clarity.
The term "or" means any one or more of the items in the list connected by "or". As an example, "x or y" means any element in the three-element set { (x), (y), (x, y) }. As another example, "x, y, or z" means any element in a seven-element set { (x), (y), (z), (x, y), (x, z), (y, z), (x, y, z) }.
The terms "comprises," "comprising," "includes," and "including" are open-ended terms and specify the presence of the stated features, but do not preclude the presence or addition of one or more other features.
The terms "first," "second," and the like may be used herein to describe various elements and these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, for example, a first element discussed in this disclosure could be termed a second element without departing from the teachings of the disclosure.
The term "coupled," unless otherwise specified, may be used to describe two elements as directly contacting each other or as indirectly connected through one or more other elements. For example, if element a is coupled to element B, element a may be directly contacting element B or indirectly connected to element B through intermediate element C. As used herein, the term "coupled" may refer to either an electrical coupling or a mechanical coupling. Similarly, the term "above … …" or "on … …" may be used to describe two elements in direct contact with each other or to describe two elements indirectly connected by one or more other elements.

In the example shown in fig. 2A, a first module substrate 111 may be provided. In some examples, the first module substrate 111 may include copper, copper alloy, nickel alloy, iron, or iron-nickel alloy. In some examples, the thickness of the first module substrate 111 may be in the range of about 125 micrometers (μm) to about 250 μm.

In the example shown in fig. 2B, the outward terminals 1111o may be provided on the bottom side of the first module substrate 111. The outward terminals 1111o may be provided by removing a portion of the first module substrate 111 from the bottom side of the first module substrate 111. In some examples, the outward terminals 1111o may be formed using an etching process.

Dielectric structure 1112 may electrically isolate outward terminals 1111o from each other. The outward terminals 1111o may be exposed from the dielectric structure 1112 at the bottom side of the first module substrate 111. In some examples, after overmolding the bottom side of the first module substrate 111, a portion of the dielectric structure 1112 may be removed by a grinding process, thereby exposing the outward terminals 1111o. The bottom side of dielectric structure 1112 may be coplanar with the bottom side of outward terminal 1111o. In some examples, the thickness of the dielectric structure 1112 may be in the range of about 87 μm to about 175 μm.

In the example shown in fig. 2D, inward terminals 1111i and traces 1111t may be disposed on the top side of the first module substrate 111. The inward terminals 1111i may be provided by removing a portion of the first module substrate 111 from the top side of the first module substrate 111. In some examples, an etching process may be used to form inward terminals 1111i.

The trace 1111t may be provided by removing a portion of the first module substrate 111 from the top side of the first module substrate 111. For example, trace 1111t may be formed by etching, as previously described with reference to inward terminal 1111i. In some examples, trace 1111t may be provided simultaneously with inward terminal 1111i. Trace 1111t may extend and couple to a side of inward terminal 1111i. Trace 1111t may extend in a generally horizontal direction over the top side of dielectric structure 1112. Trace 1111t may be exposed at the top side of first module substrate 111. Trace 1111t may be coupled to inward terminal 1111i and outward terminal 1111o. For example, at least some of the inward terminals 1111i may be coupled to the outward terminals 1111o by traces 1111t.
Fig. 2E shows a cross-sectional view of the electronic device 10 at a later stage of manufacture. In the example shown in fig. 2E, a plating layer 1111p may be provided.

In some examples, plating 1111p may be disposed on the surfaces of outward terminals 1111o, inward terminals 1111i, and traces 1111 t. In some examples, plating 1111p may be part of inward terminals 1111i or outward terminals 1111 o. In some examples, plating 1111p may include or be referred to as a coating or conductive coating. In some examples, the plating 1111p may include gold, silver, copper, platinum, tin, nickel, palladium, titanium, or tungsten. In some examples, plating 1111p may be provided by electroless plating or electroplating. In some examples, the thickness of the plating 1111p may be in the range of about 0.3 μm to about 15.2 μm. In some examples, outward terminals 1111o, inward terminals 1111i, and traces 1111t may be free of plating 1111p, such that first module substrate 111 may be incorporated into electronic device 10 without plating 1111p.
In some examples, inward terminals 1111i, outward terminals 1111o, traces 1111t, and plating 1111p may be referred to as conductive structures 1111. In other words, conductive structure 1111 may include inward terminals 1111i, outward terminals 1111o, traces 1111t, and plating 1111p. Conductive structure 1111 may include or be referred to as a conductive path, lead, terminal, pad, trace, or via. The conductive structures 1111 may transfer signals, currents or voltages within the first module substrate 111. In some examples, the first module substrate 111 may include or be referred to as a leadframe substrate, a Molded Leadframe (MLF), or a routable molded leadframe (rtMLF).
Fig. 2F shows a cross-sectional view of the electronic device 10 at a later stage of fabrication. In the example shown in fig. 2F, the module assembly 115 may be disposed on the first module substrate 111. In some examples, the module assembly 115 may include or be referred to as a power assembly, a power device, a power semiconductor device, a Metal Oxide Semiconductor Field Effect Transistor (MOSFET) device, a semiconductor die, a semiconductor chip, or a semiconductor package. In some examples, the module assembly 115 may include or be referred to as a compound semiconductor power device, such as a SiC power MOSFET or a GaN power device. Module assembly 115 may be coupled to inward terminals 1111i. The inward terminals 1111i provide a connection path between the module assembly 115 and the first module substrate 111. In some examples, module assembly 115 may be coupled to plating 1111p on inward terminals 1111i by an interface material. For example, an interface material may be provided on the plating 1111p, and the module assembly 115 may be located on the interface material to allow the module assembly 115 to be coupled to the plating 1111p through a reflow process. In some examples, the interface material may include a conductive adhesive, a conductive epoxy, a solder paste, or an Ag sintering paste.
In some examples, module assembly 115 may include assembly terminals 1151, 1152, and 1153.

In some examples, the plating 1121p may be provided by electroless plating or electroplating. In some examples, the thickness of the plating 1121p may be in the range of about 0.3 μm to about 15.2 μm. In some examples, the outward terminals 1121o, inward terminals 1121i, and traces 1121t may be free of plating 1121p, such that the second module substrate 112 may be incorporated into the electronic device 10 without plating 1121p.
In some examples, the inward terminal 1121i, the outward terminal 1121o, the trace 1121t, and the plating 1121p may be referred to as a conductive structure 1121. In other words, the conductive structure 1121 may include an inward terminal 1121i, an outward terminal 1121o, a trace 1121t, and a plating 1121p. In some examples, the conductive structure 1121 may include or be referred to as a conductive path, lead, terminal, pad, trace, or via. The conductive structure 1121 may pass signals, currents, or voltages within the second module substrate 112.
In some examples, the second module substrate 112 may include or be referred to as a leadframe substrate, a molded substrate, or rtMLF. Although the first module substrate 111 and the second module substrate 112 are described as lead frames, it is contemplated and understood that in some examples, the first module substrate 111 or the second module substrate 112 may comprise a laminate or preformed substrate. The preformed substrate may be fabricated prior to attachment to the electronic device and may include a dielectric layer between respective conductive layers. The conductive layer may comprise, for example, copper and may be formed using an electroplating process. The dielectric layer may be a non-photodefinable layer that may be attached in a preformed film rather than in a liquid form, and may comprise a resin with a filler such as threads, wovens, or other inorganic particles for rigid or structural support. Since the dielectric layer is non-photodefinable, features such as vias or openings can be formed by using drilling or laser. In some examples, the dielectric layer may include a prepreg material or a flavoured-film stack (ABF). The preformed substrate may comprise a permanent core structure or carrier, such as a dielectric material including Bismaleimide Triazine (BT) or FR4, and the dielectric layer and conductive layer may be formed on the permanent core structure. In other examples, the preformed substrate may be a coreless substrate omitting the permanent core structure, and the dielectric layer and the conductive layer may be formed on a sacrificial carrier that is removed after formation of the dielectric layer and the conductive layer and prior to attachment to the electronic device. The preformed substrate may be referred to as a Printed Circuit Board (PCB) or a laminate substrate. Such a preformed substrate may be formed by a half-addition process or a modified half-addition process.

In some examples, the module interconnect 113 may be provided by a reflow process after a conductive material including solder is formed on the plated layer 1121p of the inward terminal 1121i. In some examples, the thickness of the module interconnect 113 may be in the range of about 150 μm to about 365 μm.
Fig. 2M shows a cross-sectional view of the electronic device 10 at a later stage of fabrication. In the example shown in fig. 2M, the second module substrate 112 may be disposed over the first module substrate 111. In some examples, the second module substrate 112 may be flipped such that the inward terminals 1121i of the second module substrate 112 are oriented toward the module assembly 115 and the first module substrate 111, and the outward terminals 1121o are located on the top side of the second module substrate 112. In some examples, after positioning the second module substrate 112 on the first module substrate 111, the second module substrate 112 may be coupled to the first module substrate 111 by, for example, thermocompression bonding. The module interconnect 113 may couple the second module substrate 112 to the first module substrate 111. For example, module interconnect 113 may be coupled to inward terminals 1111i or traces 1111t of first module substrate 111. The module assembly 115 may be coupled to the inward terminals 1121i or traces 1121t of the second module substrate 112. In some examples, component terminals 1153 of module component 115 may be coupled to inward terminals 1121i or traces 1121t of second module substrate 112. The side of the first module substrate 111 to which the module assembly 115 is attached is a first inward-facing example. The side of the first module substrate 111 opposite to the first inward side is an example of the first outward side. The side of the second module substrate 112 to which the module assembly is attached is a second inward facing example. The side of the second module substrate 112 opposite the second inward side is an example of the second outward side. In addition, FIG. 2M illustrates an example where the module assemblies 115 are located in the same plane or coplanar. Fig. 2M further shows an example in which the embedded module 11 does not contain any spacers.
