However, it should be understood that this disclosure provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of this disclosure.
[0020] Figure 1A This illustration shows a cross-sectional view of a semiconductor device package 1A according to some embodiments of the present disclosure. The semiconductor device package 1A includes a substrate 10, a support structure 11, an antenna 12, electronic components 14, and electrical contacts 15.
[0021] For example, substrate 10 may be 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. Substrate 10 may include opposing surfaces 101 and 102 (e.g., an upper surface and a lower surface). Substrate 10 may include interconnect structures (e.g., electrical connections), such as a redistribution layer (RDL). Substrate 10 may include metal layers 10c1 and 10c2 on its surfaces 101 and 102, respectively. In some embodiments, metal layer 10c1 is a ground layer.
[0022] A support structure 11 is disposed on the surface 101 of the substrate 10. For example, the support structure 11 is connected to the surface 101 of the substrate 10 via a connecting element 10a. In some embodiments, the support structure 11 is formed of or contains a dielectric material. For example, the support structure 11 may comprise a molding compound, prepreg composite fibers (e.g., a prepreg), borophosphosilicate glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, undoped silicate glass (USG), any combination thereof, or the like. Examples of molding compounds may include, but are not limited to, epoxy resins containing fillers dispersed therein. Examples of prepregs may include, but are not limited to, multilayer structures formed by stacking or laminating multiple prepreg materials / sheets.
[0023] Antenna 12 is mounted on support structure 11. Antenna 12 is spaced from surface 101 of substrate 10. For example, a gap exists between antenna 12 and substrate 10. Antenna 12 includes dielectric layer 12d and antenna pattern 12a. Antenna pattern 12p is embedded in dielectric layer 12d and exposed from surfaces 12d1 and 12d2 of dielectric layer 12d. For example, surface 12p1 of antenna pattern 12p is substantially coplanar with surface 12d1 of dielectric layer 12d, and surface 12p2 of antenna pattern 12p is substantially coplanar with surface 12d2 of dielectric layer 12d. For example, the thickness of antenna pattern 12p is substantially the same as the thickness of dielectric layer 12d. For example, surfaces 12p1 and 12p2 of antenna pattern 12a are exposed to air. For example, surfaces 12p1 and 12p2 of antenna pattern 12a are in direct contact with air. In some embodiments, the semiconductor device package 1A is disposed within a vacuum space or vacuum cavity, and thus the surfaces 12p1 and 12p2 of the antenna pattern 12a are exposed to the vacuum. In some embodiments, the antenna pattern 12p is or comprises a conductive material, such as a metal or metal alloy. Examples of conductive materials include gold (Au), silver (Ag), aluminum (Al), copper (Cu), or alloys thereof.
[0024] Antenna pattern 12p can be electrically connected to metal layer 10c1 via connection structure 12f. In some embodiments, connection structure 12f can act as a feed element to provide a signal to antenna pattern 12p. In some embodiments, connection structure 12f connects antenna pattern 12p to ground via metal layer 10c1. In some embodiments, connection structure 12f may include, but is not limited to, solder balls, metal pillars, bonding wires, or stacked vias. In some embodiments, connection structure 12f comprises Au, Ag, Al, Cu, or alloys thereof. In some embodiments, connection structure 12f is omitted, and metal layer 10c1 can be electromagnetically coupled to antenna pattern 12p. In some embodiments, metal layer 10c1 and antenna 12 can be referred to as antenna structure.
[0025] In some embodiments, the antenna pattern 12p can be as follows: Figure 1A The diagram shows a uniform width. In some embodiments, such as... Figure 1C and Figure 1D As shown in the cross-sectional view of antenna 12 according to some embodiments of this disclosure, antenna pattern 12p includes a non-uniform width. For example, as... Figure 1C As shown, the width of surface 12p1 of antenna pattern 12p is greater than the width of surface 12p2 of antenna pattern 12p. For example, as... Figure 1D As shown, the width of the antenna pattern 12p between surface 12p1 and surface 12p2 is greater than the width of surface 12p1 or 12p2 of the antenna pattern 12p.
[0026] A dielectric layer 12d is disposed on a support structure 11. In some embodiments, the dielectric layer 12d is in direct contact with the support structure 11. In some embodiments, the dielectric layer 12d has a lateral surface 12d3 exposed to air. In some embodiments, the lateral surface 12d3 of the dielectric layer 12d is exposed to the exterior of the semiconductor device package 1A. In some embodiments, the lateral surface 12d3 of the dielectric layer 12d is substantially coplanar with the lateral surface 113 of the support structure 11. In some embodiments, the dielectric layer 12d may comprise a molding compound, a prepreg composite fiber (e.g., a prepreg), BPSG, silicon oxide, silicon nitride, silicon oxynitride, USG, any combination thereof, or the like. Examples of molding compounds may include, but are not limited to, epoxy resins containing fillers dispersed therein. Examples of prepregs may include, but are not limited to, multilayer structures formed by stacking or laminating multiple prepreg materials / sheets. In some embodiments, the dielectric layer 12d and the support structure 11 are formed of or comprise the same material. For example, both the dielectric layer 12d and the support structure 11 are formed of a molding compound. Alternatively, the dielectric layer 12d and the support structure 11 are formed of different materials. In some embodiments, the antenna 12 and the support structure 11 may be collectively referred to as an antenna structure.
[0027] In some embodiments, such as Figure 1A and Figure 1B (The explanation is as follows) Figure 1A As shown in the perspective view of the semiconductor device package 1A, the substrate 10, support structure 11, and antenna 12 define an air gap. For example, there is no dielectric material between the antenna 12 and the metal layer 10c1. Therefore, RF signals are transmitted or received by the antenna 12 via air. Since the Df / Dk (i.e., 0 / 1) of air is lower than that of any dielectric material, the signal attenuation or loss of the RF signal can be reduced, which will improve the performance of the antenna 12 (e.g., more preferably 1.3 to 2.3 times). In addition, since the antenna pattern 12p is not required to be connected to the dielectric layer in a direction perpendicular to the surfaces 12p1 or 12p2 of the antenna pattern 12p, the surfaces 12p1 and 12p2 of the antenna pattern 12p are relatively smooth (e.g., no roughness is required on the surfaces 12p1 and 12p2 of the antenna pattern 12p), which will improve the performance of the antenna 12.
[0028] Return to reference Figure 1A Electronic component 14 is disposed on surface 102 of substrate 10 and electrically connected to substrate 10 via, for example, flip-chip or wire bonding technology. Electronic component 14 may be a chip or die, comprising a semiconductor substrate, one or more integrated circuit devices, and one or more overlay interconnect structures thereon. Integrated circuit devices may comprise active devices such as transistors and / or passive devices such as resistors, capacitors, inductors, or combinations thereof.
[0029] Electrical contact 15 is disposed on surface 102 of substrate 10 and electrically connected to metal layer 10c2 exposed from protective layer 10s (e.g., solder mask or solder resist). In some embodiments, electrical contact 15 is a solder ball. In other embodiments, electrical contact 15 may be a copper pillar or any other suitable electrical contact.

In some embodiments, the through-hole 11v comprises Au, Ag, Al, Cu, or an alloy thereof. The through-hole 11v may enhance the strength of the support structure 11.

Antenna 22 includes dielectric layer 22d and antenna pattern 22a. Antenna pattern 22p is embedded in dielectric layer 22d and exposed from surfaces 22d1 and 22d2 of dielectric layer 22d.

For example, the thickness of antenna pattern 22p is substantially the same as the thickness of dielectric layer 22d. For example, surfaces 22p1 and 22p2 of antenna pattern 22a are exposed to air. For example, surfaces 22p1 and 22p2 of antenna pattern 22a are in direct contact with air.

[0063] As used herein, the terms “approximately,” “generally,” “roughly,” and “about” are used to describe and account for minor variations. When used in conjunction with an event or situation, the terms may refer to instances where the event or situation has clearly occurred or instances where the event or situation is very close to occurring. For example, when used in conjunction with numerical values, 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 numerical values is less than or equal to ±10% of the average of the values, 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%, then the two numerical values can be considered “generally” or “about” the same. For example, "generally parallel" can refer to an angular variation of less than or equal to ±10° relative to 0°, 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°. Similarly, "generally perpendicular" can refer to a variation of ±10° relative to 90°, 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°.
[0064] For example, if the displacement between two surfaces is equal to or less than 5 µm, equal to or less than 2 µm, equal to or less than 1 µm, or equal to or less than 0.5 µm, then the two surfaces can be considered coplanar or substantially coplanar. If the displacement between any two points on a surface relative to the flat surface is equal to or less than 5 µm, equal to or less than 2 µm, equal to or less than 1 µm, or equal to or less than 0.5 µm, then the surface can be considered planar or substantially planar.
[0065] As used herein, the terms “conductive,” “electrically conductive,” and “conductivity” refer to the ability to conduct electric current. Conductive materials are generally those that exhibit minimal or zero resistance to the flow of electric current. One measure of conductivity is Siemens per meter (S / m). Typically, conductive materials have a conductivity greater than approximately 10. 4 S / m (e.g., at least 10) 5 S / m or at least 10 6 A material has a conductivity of S / m. The conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the conductivity of a material is measured at room temperature.
[0066] Unless the context clearly specifies otherwise, the singular terms “a” and “described” as used herein may include multiple indicators. In the description of some embodiments, a component disposed “on” or “above” another component may cover situations where the former component is directly on the latter component (e.g., in physical contact with it), and situations where one or more intervening components are located between the former component and the latter component.
[0067] Unless otherwise specified, spatial descriptions such as “above,” “below,” “upward,” “left,” “right,” “downward,” “top,” “bottom,” “vertical,” “horizontal,” “side,” “higher,” “lower,” “upper,” “above,” and “below” refer to the orientation shown in the figures. It should be understood that the spatial descriptions used herein are for illustrative purposes only, and actual embodiments of the structures described herein may be arranged in space in any orientation or manner, provided that the advantages of the embodiments of this disclosure are not deviated from by such arrangement.
