[0019] Figure 1A A cross-sectional view of an electrical device 1a according to some embodiments of the present invention is shown.

[0020] The electrical device 1a includes a semiconductor packaging device 1a1, a motherboard 50, and a thermally conductive material 60.

[0026] Encapsulation 40 is disposed on or covers surface 101 of substrate 10. Encapsulation 40 covers, encapsulates, or surrounds electronic component 20 and connection element 95. Encapsulation 40 exposes a portion of each of the connection elements 95 for electrical connection. Encapsulation 40 may comprise epoxy resin with filler, molding compound (e.g., epoxy molding compound or other molding compound), polyimide, phenolic compound or material, material having silicone dispersed therein, or combinations thereof.

[0027] Electronic components 70 and 75 are disposed on surface 102 of substrate 10. Electronic components 70 and / or 75 may be chips or dies containing a semiconductor substrate, one or more integrated circuit devices, and one or more overlying interconnect structures. Integrated circuit devices may include active devices such as transistors and / or passive devices such as resistors, capacitors, inductors, or combinations thereof.

[0028] Encapsulant 80 is disposed on or covers surface 102 of substrate 10. Encapsulant 80 covers, encapsulates, or surrounds electronic components 70 and 75. Encapsulant 80 may comprise epoxy resin with filler, molding compound (e.g., epoxy molding compound or other molding compound), polyimide, phenolic compound or material, material having silicone dispersed therein, or combinations thereof.

[0029] The antenna device 90 is disposed near the surface 102 of the substrate 10, for example, the antenna device 90 is disposed on the surface 102 of the substrate 10. Figure 1A In the embodiment shown, the antenna device 90 includes an antenna pattern comprising a plurality of portions 93.

[0030] Connecting element 95 is disposed on surface 101 of substrate 10 and is surrounded or encapsulated by encapsulant 40. Figure 1AIn the embodiments shown, each connection element 95 has a portion exposed from the encapsulation 40 and connected to a pad 55 of the motherboard 50. Connection element 95 may include solder balls. In some embodiments, connection element 95 may serve as an I / O connection element between the semiconductor package 1a1 and the motherboard 50 for signal transmission. For example, connection element 95 may be a portion of a substrate insert containing circuitry and pads on its surface. In some embodiments, connection element 95 may be or may include a through-molded via (TMV) filled with a conductive material. In some embodiments, connection element 95 may be or may include a conductive pillar, which may be formed by, for example, plating to form the pillar and molding or encapsulating the pillar and exposing it.

[0031] The motherboard 50 may include, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass fiber-based copper foil laminate. The motherboard 50 may include interconnect structures, such as a redistribution layer (RDL) or grounding elements.

[0032] Thermally conductive material 60 is disposed between the semiconductor packaging device 1a1 and the motherboard 50. For example... Figure 1A As shown, thermally conductive material 60 is disposed between the thermally conductive layer 30 of the semiconductor package device 1a1 and the pad 55 of the motherboard 50. The thermally conductive material 60 contacts the surface 301 of the thermally conductive layer 30. In some embodiments, the lateral surface 303 of the thermally conductive layer 30 may be exposed from the electronic component 20 or the encapsulation 40 and may contact or be covered by the thermally conductive material 60. The thermally conductive material 60 may contain solder. In some embodiments, the surface 601 of the thermally conductive material 60 is coplanar with the surface 951 of the connecting element 95.

[0033] In some embodiments, when a semiconductor package 1a1 is mounted on a motherboard 50, a thermally conductive layer 30 comprising multiple segmented or spaced portions 35 can improve or facilitate alignment between the thermally conductive layer 30 (or the semiconductor package 1a1) and the thermally conductive material 60 (which is a heat dissipation structure) of the motherboard 50. Additionally, it can improve the high consistency or high control between the thermally conductive layer 30 (or the thermally conductive material 60) and the connecting element 95, which can prevent or reduce delamination between the semiconductor package 1a1 and the motherboard 50. In some embodiments, the separated portions 35 of the thermally conductive layer 30 can prevent heat accumulation or heat concentration and improve reliability. When the thermally conductive layer 30 is a single piece, a mismatch in the coefficient of thermal expansion (CTE) between the thermally conductive layer 30 and the thermally conductive material 60 and / or the motherboard 50 can cause misalignment or high inconsistency. In some embodiments, a single-piece thermally conductive layer 30 can cause relatively large areas of wetting between the connecting element 60 (which may be a single piece) and the thermally conductive layer 30 during, for example, a reflow process. Extensive wetting may cause the package to become misaligned / bent / tilted, making the gap between one or more connecting elements 95 and the motherboard 50 too far for the connecting element 95 and the motherboard 50 to be connected, which may cause functional failure.

The portion 35 of the thermally conductive layer 30 may contain epoxy resin, which may improve the adhesion between the portion 35 and the encapsulant 40 (which may also contain epoxy resin) or between the portion 35 and the electronic component 20. The lateral surface 603 of the thermally conductive material 60 may be partially covered by the encapsulant 40. A connecting element 65 is disposed between the connecting element 95 and the motherboard 50 and between the thermally conductive material 60 and the motherboard 50. The connecting element 65 may have similar properties to the connecting element 95 or the thermally conductive material 60 and may contain solder.

[0036] In some embodiments, the encapsulant 40 may expose a portion of the lateral surface 303 of the thermally conductive layer 30 or a portion of the lateral surface 603 of the thermally conductive material 60. The exposed portions of the lateral surfaces 303 and / or 603 may be wetted or in contact with the connecting element 65. Controlling the amount of exposed portions of the lateral surfaces 303 and / or 603 prevents bridging between adjacent connecting elements 65.

[0061] As used herein, the terms “approximately,” “substantially,” “substantially,” and “about” are used to describe and explain small variations. When used in conjunction with an event or situation, the terms may refer to examples where the event or situation occurred precisely or where it occurred very approximately. For example, when used in conjunction with a numerical value, the terms may refer to a range of variation less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two values ​​is less than or equal to ±10% of the average of the values ​​(e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), then the two values ​​can be considered "substantially" or "approximately" the same.
