[0038] In the following description, specific details are set forth to provide a thorough understanding of various aspects of this disclosure. However, those skilled in the art will understand that these aspects can be practiced without these specific details. For example, circuits may be shown as block diagrams to avoid obscuring aspects with unnecessarily detailed information. In other instances, well-known circuits, structures, and techniques may not be shown in detail to avoid obscuring aspects of this disclosure.
[0039] This disclosure describes a substrate including at least one dielectric layer, a plurality of interconnects, and a bent antenna coupled to a surface of the substrate. The bent antenna is bent relative to a surface of the substrate such that at least a portion of the bent antenna is offset (e.g., vertically offset) from the surface of the substrate (e.g., a flat surface). The bent antenna is coupled to the surface of at least one dielectric layer. The bent antenna may be coupled to a plurality of interconnects. The bent antenna may include a concave antenna. The concave antenna may be concave relative to the surface of the substrate. The bent antenna may include a nonlinear surface. The bent antenna may be implemented in the substrate as part of an antenna device. The bent antenna may be implemented in the substrate as part of a package, such as an antenna in-package (AiP). The package may include a radio frequency front-end (RFFE) package. The substrate may include more than one antenna. For example, the substrate may include several antennas, wherein at least one antenna is a bent antenna. The bent antenna may include a dome shape. As will be further described below, the bent antenna provides better antenna gain in a particular direction than a planar antenna of similar size, thus providing an antenna with better directivity and better signal transmission and / or reception in one or more particular directions. In some implementations, the bent antenna may be located close to a bent antenna ground interconnect configured to be coupled to ground. The bent antenna ground interconnect can help improve the performance of the bent antenna by helping to prevent signal interference from other interconnects and / or antennas from passing through the bent antenna.
[0040] Exemplary package having a substrate including a flexible antenna
[0041] Figure 2The illustration shows a contour view of a package 200 including a substrate 202, an integrated device 203, and an integrated device 205. The integrated device 203 is coupled to the substrate 202 via a plurality of solder interconnects 230. The integrated device 205 is coupled to the substrate 202 via a plurality of solder interconnects 250. The substrate 202 includes at least one dielectric layer 220, a plurality of interconnects 222, and a bent antenna 206. The bent antenna 206 can be configured to be electrically coupled to the integrated device 203 and / or the integrated device 205. For example, the bent antenna 206 can be configured to be electrically coupled to the integrated device 203 via a plurality of interconnects 222 and a plurality of solder interconnects 230, and the bent antenna 206 can be configured to be electrically coupled to the integrated device 205 via a plurality of interconnects 222 and a plurality of solder interconnects 250.
[0042] A curved antenna 206 may be located on a surface of substrate 202 (e.g., a first surface, a top surface). For example, curved antenna 206 may be located on the surface of at least one dielectric layer 220. Curved antenna 206 may be coupled to a plurality of interconnects 222. Substrate 202 may include an antenna dielectric layer 260. Antenna dielectric layer 260 may be formed and positioned on the surface of at least one dielectric layer 220. Antenna dielectric layer 260 may be located between curved antenna 206 and the surface of substrate 202. For example, antenna dielectric layer 260 may be located between curved antenna 206 and at least one dielectric layer 220 of substrate 202. Antenna dielectric layer 260 may include the same material as at least one dielectric layer 220. Antenna dielectric layer 260 includes a non-linear profile shape. For example, antenna dielectric layer 260 includes a curved profile shape. Curved antenna 206 may be coupled to and / or formed on the curved profile shape of antenna dielectric layer 260. The shape of the bent antenna 206 can be defined by the shape of the bent profile of the antenna dielectric layer 260. The bent antenna 206 is bent relative to the surface of the substrate 202 such that at least a portion of the bent antenna 206 is offset (e.g., vertically offset) from the surface of the substrate 202 (e.g., the surface of the dielectric layer 220 of the substrate 202, a flat surface of the substrate 202). The bent antenna 206 includes a nonlinear shape and / or a nonlinear surface. Figure 2 As shown, the curved antenna 206 includes a concave shape. The concave shape may include a dome shape. However, the shape and / or curvature of the curved antenna 206 may vary with different embodiments. Although a curved antenna is shown, the substrate 202 may include several antennas, wherein at least one of the antennas is a curved antenna. For example, the substrate 202 may include several combinations of curved antennas and / or planar antennas. In some embodiments, all antennas may be curved antennas (e.g., curved antennas with the same curve or different curves).
[0043] The curved antenna 206 can be a component for signal transmission and / or reception. That is, the curved antenna 206 can be configured to transmit at least one signal for at least one frequency and / or receive at least one signal for at least one frequency. As will be further described below, the curved antenna provides better directivity and better antenna gain compared to a planar antenna of similar size and / or shape.
[0044] Package 200 may be an antenna-in-package (AiP). Package 200 may be a radio frequency (RF) package. Package 200 (or any package described in this disclosure) may be part of a radio frequency front-end (RFFE) package. Package 200 may be configured to provide wireless fidelity (WiFi) communication and / or cellular communication (e.g., 2G, 3G, 4G, 5G). Package 200 may be configured to support Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), and / or Long Term Evolution (LTE). Package 200 may be configured to transmit and receive signals with different frequencies and / or communication protocols.
[0045] Integrated devices (e.g., 203, 205) may include bare dies (e.g., exposed dies). Integrated devices may include radio frequency (RF) devices, analog devices, passive devices, filters, capacitors, inductors, antennas, transmitters, receivers, surface acoustic wave (SAW) filters, bulk acoustic wave (BAW) filters, light-emitting diode (LED) integrated devices, silicon (Si)-based integrated devices, silicon carbide (SiC)-based integrated devices, GaAs-based integrated devices, GaN-based integrated devices, memories, power management processors, and / or combinations thereof.
[0046] Figure 3 and Figure 4 The diagram illustrates the antenna gain for two antennas of similar size, one of which is a planar antenna and the other is a curved antenna. Figure 3 A planar antenna 306 with a width of approximately 5 millimeters (mm) is illustrated. The planar antenna 306 is not offset from a surface (e.g., the surface of a substrate) (e.g., not perpendicularly offset). Figure 3 The figure shows that the maximum antenna gain of the planar antenna 306 in a specific direction is approximately 4.5 dBi. Antenna gain indicates the power emitted by an antenna in a specific direction compared to an isotropic antenna. An isotropic antenna is a theoretical antenna that radiates equally in all directions. Higher antenna gain (dBi) means better directivity of the antenna in a specific direction.
[0047] Figure 4A curved antenna 406 with a width of approximately 4 millimeters (mm) is illustrated. However, the total surface width of the curved antenna 406 can be approximately 5 mm. At least a portion of the curved antenna 406 is offset (e.g., vertically offset) from a surface (e.g., the surface of a substrate). In this example, some portions of the curved antenna 406 can be offset (e.g., vertically offset) from the surface by up to 0.1 mm. Figure 4 As shown in the figure, the maximum antenna gain of the curved antenna 406 in a specific direction is approximately 5.2 dBi. Therefore, the curved antenna 406 receives and / or transmits signals better than the planar antenna 306 in certain directions and provides better directivity, even though the curved antenna 406 and the planar antenna 306 have similar footprint shapes and surface areas. Although the curved antenna 406 may actually be thicker due to offset from the surface, the increase in size in the vertical direction is offset by the decrease in size in the lateral direction. In this example, better antenna gain (and therefore better directivity) is achieved, and the effective footprint of the antenna is reduced by 1 mm while the thickness increases by only 0.1 mm. The curved antenna 406 can represent any of the curved antennas described in this disclosure. For example, the curved antenna 406 can represent the curved antenna 206.
[0048] Different implementations may have different antenna configurations, designs, shapes, and / or sizes. Figure 5 Another example of a package including substrates with different antenna configurations is illustrated. Figure 5 The illustration shows a outline view of a package 500 including a substrate 502, an integrated device 203, and an integrated device 205. Package 500 is similar to... Figure 2 Package 200. Substrate 502 is similar to substrate 202 and therefore includes components similar to or the same as substrate 202.
[0049] Substrate 502 includes at least one dielectric layer 220, a plurality of interconnects 222, a first antenna dielectric layer 570, an antenna ground interconnect 508, a second antenna dielectric layer 560, and a curved antenna 506. The first antenna dielectric layer 570 is coupled to and / or formed on the surface of substrate 502. For example, the first antenna dielectric layer 570 is coupled to and / or formed on the surface of at least one dielectric layer 220 of substrate 502. The first antenna dielectric layer 570 includes a curved profile shape (e.g., a non-linear profile shape). The antenna ground interconnect 508 is coupled to and / or formed on the curved profile shape of the first antenna dielectric layer 570. The antenna ground interconnect 508 has a curved shape that can be defined by the curved profile shape of the first antenna dielectric layer 570. The antenna ground interconnect 508 can be configured to be coupled to ground. Antenna ground interconnect 508 can be coupled to one or more interconnects from a plurality of interconnects 222. A second antenna dielectric layer 560 is coupled to and / or formed on the antenna ground interconnect 508. The second antenna dielectric layer 560 may include a curved profile shape. A curved antenna 506 is coupled to and / or formed on the curved profile of the second antenna dielectric layer 560. The shape of the curved antenna 506 can be defined by the shape of the curved profile of the second antenna dielectric layer 560. Antenna ground interconnect 508 and curved antenna 506 can be located on the surface of substrate 502 (e.g., on the surface of at least one dielectric layer 220). Antenna ground interconnect 508 and / or curved antenna 506 can be coupled to corresponding interconnects from a plurality of interconnects 222. The use of antenna ground interconnect 508 helps to isolate and / or shield the curved antenna 506 from other signals, which in turn helps the curved antenna 506 to better transmit and / or receive signals.
[0050] Although a bent antenna is shown, substrate 502 may include several antennas, wherein at least one of the antennas is a bent antenna. Substrate 502 may include Figure 2 and Figure 5 A combination of antenna designs. Therefore, the substrate may include those from... Figure 2 and Figure 5 Several combinations of various antenna designs.
[0051] Figure 6 Another example of a package including substrates with different antenna configurations is illustrated. Figure 6 The illustration shows a outline view of a package 600 including a substrate 602, an integrated device 203, and an integrated device 205. Package 600 is similar to... Figure 5Package 500. Substrate 602 is similar to substrate 502 and therefore includes components similar to or the same as substrate 502.
[0052] The substrate 602 includes at least one dielectric layer 220, a plurality of interconnects 222, a gap 670, an antenna ground interconnect 608, an antenna dielectric layer 660, and a bent antenna 506.
[0053] Antenna ground interconnect 608 is coupled to and / or formed on the surface of substrate 602. A gap 670 is located between antenna ground interconnect 608 and the surface of substrate 602 (e.g., the surface of at least one dielectric layer 220). The gap can be at least one area without solid material. The gap can include a cavity. The gap can be occupied by a gas (e.g., air). The size and / or shape of the gap 670 can vary. For example, the gap 670 can occupy part or all of the space between dielectric layer 220 and antenna ground interconnect 608. Antenna ground interconnect 608 has a curved shape and / or a curved profile surface. Antenna ground interconnect 608 includes at least one opening 609. Antenna ground interconnect 608 can be configured to be coupled to ground. Antenna ground interconnect 608 can be coupled to interconnects from a plurality of interconnects 222. Antenna dielectric layer 660 is coupled to and / or formed on antenna ground interconnect 608. The second antenna dielectric layer 660 may include a curved profile shape. A curved antenna 506 is coupled to and / or formed on the curved profile of the antenna dielectric layer 660. The shape of the curved antenna 506 may be defined by the shape of the curved profile of the antenna dielectric layer 660. The antenna ground interconnect 608 and the curved antenna 506 may be located above the surface of the substrate 602 (e.g., above the surface of at least one dielectric layer 220). The antenna ground interconnect 608 and / or the curved antenna 506 may be coupled to corresponding interconnects from a plurality of interconnects 222. The use of the antenna ground interconnect 608 helps to isolate and / or shield the curved antenna 506 from other signals, which in turn helps the curved antenna 506 to better transmit and / or receive signals. The gap 670 may be occupied by a gas (e.g., air) that provides very good dielectric properties (e.g., low dielectric constant), which helps to minimize signal coupling and dielectric losses (e.g., minimize power losses). The gap 670 can also help seal any microelectromechanical system (MEMS) device below the gap 670, such as SAW filters and / or BAW filters using bent antennas, accelerometers, and gyroscopes (for wireless sensing).
[0054] Although a bent antenna is shown, substrate 602 may include several antennas, wherein at least one of the antennas is a bent antenna. Substrate 602 may include Figure 2 and Figures 5-6 A combination of antenna designs. Therefore, the substrate may include those from... Figure 2 and Figures 5-6 Several combinations of various antenna designs. In some embodiments, when the substrate (e.g., 202, 502, 602) includes several antennas, all of the antennas in the antenna can be flexible antennas (e.g., having different, similar, or identical designs, sizes, and / or shapes).
[0055] Bendable antenna designs can be implemented in various ways. In some implementations, the bendable antenna can be integrated as part of an antenna device. Figure 7 The diagram illustrates a contour view of package 700 comprising multiple discrete antenna devices, wherein at least some of the discrete antenna devices include bent antennas.

Substrate 702 includes at least one dielectric layer 720 and a plurality of interconnects 722. Substrate 702 includes a first surface (e.g., a top surface) and a second surface (e.g., a bottom surface). Integrated device 203 is coupled to the second surface of substrate 702 via a plurality of solder interconnects 230. Integrated device 205 is coupled to the second surface of substrate 702 via a plurality of solder interconnects 250. Integrated device 203 and the second integrated device 205 may include dies (e.g., processor dies, memory dies). Passive device 704 is coupled to the second surface of substrate 702 via a plurality of solder interconnects 740. The passive device may include a capacitor or an inductor. For example, passive device 704 is a capacitor. Connector 714 is coupled to the second surface of substrate 702.
[0057] Package 700 may include a sealing layer 710. Sealing layer 710 may be formed on a second surface of substrate 702.

Sealing layer 710 may be a component for sealing.
[0058] Package 700 may include connector 714. Connector 714 may be configured to allow package 700 to be electrically coupled to one or more other devices. Different implementations may use different types of connections to electrically couple package 700 to other devices. For example, package 700 may be coupled to other devices via wiring and / or flexible interconnects. Power may be supplied to package 700 via connector 714.
[0059] Figure 7 The figure illustrates a first antenna device 750, a second antenna device 760, a third antenna device 770, and a fourth antenna device 780 coupled to a first surface of a substrate 702. The first antenna device 750 is coupled to the first surface of the substrate 702 via a plurality of first solder interconnects 752. The second antenna device 760 is coupled to the first surface of the substrate 702 via a plurality of second solder interconnects 762. The third antenna device 770 is coupled to the first surface of the substrate 702 via a plurality of third solder interconnects 772. The fourth antenna device 780 is coupled to the first surface of the substrate 702 via a plurality of fourth solder interconnects 782. The first antenna device 750, the second antenna device 760, the third antenna device 770, and the fourth antenna device 780 may all be discrete antenna devices. Each antenna device (e.g., 750, 760, 770, 780) may include at least one antenna, such as a curved antenna and / or a planar antenna. For example, the first antenna device 750 includes a curved antenna 705, the second antenna device 760 includes a curved antenna 706, the third antenna device 770 includes a curved antenna 707, and the fourth antenna device 780 includes a planar antenna 708.
[0060] The first antenna device 750, the second antenna device 760, the third antenna device 770, the fourth antenna device 780, and / or combinations thereof can be configured to provide Wi-Fi communication and / or cellular communication (e.g., 2G, 3G, 4G, 5G). The first antenna device 750, the second antenna device 760, the third antenna device 770, the fourth antenna device 780, and / or combinations thereof can be configured to support Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), and / or Long Term Evolution (LTE). In some embodiments, one or more of the antenna devices (e.g., 750, 760, 770, 780) can be configured as proximity sensors. When a particular antenna device is configured to operate as a proximity sensor, that particular antenna device can be able to detect the placement and / or movement of one or more objects (e.g., a hand, a finger) in the vicinity of the particular antenna device.
[0061] The first antenna device 750, the second antenna device 760, the third antenna device 770, the fourth antenna device 780, and / or combinations thereof can be configured to transmit and receive signals with different frequencies and / or communication protocols. The first antenna device 750 can be a component for transmitting and / or receiving a first signal. The second antenna device 760 can be a component for transmitting and / or receiving a second signal. The third antenna device 770 can be a component for transmitting and / or receiving a third signal. The fourth antenna device 780 can be a component for transmitting and / or receiving a fourth signal. The first signal, the second signal, the third signal, and / or the fourth signal can have the same or different properties. For example, the signals can have the same or different frequencies and / or communication protocols. The signals can be analog signals or digital signals.
[0062] One advantage of using discrete antenna devices is the ability to design and configure packages to meet the specific operational requirements of cellular network operators without having to redesign the entire substrate. Therefore, various discrete antenna devices can be mixed and matched together to work with different cellular network operators. Antenna devices (e.g., 750, 760, 770, 780) can be discrete from substrate 702 because the antenna devices are manufactured during a process separate from the fabrication of substrate 702. Another advantage of discrete antenna devices is that they are not limited by the size, dimensions, and manufacturing constraints of substrate 702. For example, as will be further described below, antenna devices can be partially suspended above substrate 702.
[0063] Different implementations may use the same or different types of antenna devices. Antenna devices may have the same size, shape and / or configuration, or they may have different sizes, shapes and / or configurations.

In some embodiments, Figure 25 Method 2500 can be used to provide or manufacture the invention described in this disclosure. Figure 8 Antenna device 800. However, method 2500 can be used to provide or manufacture any antenna device described in this disclosure.
[0133] It should be noted that Figure 25 The sequence can combine one or more processes to simplify and / or clarify the method for providing or manufacturing an antenna device. In some implementations, the order of the processes can be changed or modified.
[0134] The method (at 2505) forms one or more dielectric layers (e.g., 402, 410, 412). Depending on the type of antenna device being manufactured, the dielectric layer may include a core layer and / or a ceramic layer. Forming the dielectric layer may include a deposition process, a lamination process, and / or include providing one or more dielectric films.
[0135] The method (at 2510) forms a plurality of interconnects (e.g., 1202, 1212) in and on dielectric layers (e.g., 802, 810, 812). A plating process can be used to form the interconnects. However, other processes can be used to form the interconnects. In some embodiments, chemical vapor deposition (CVD) and / or physical vapor deposition (PVD) processes can be used to form the interconnects. Additionally, sputtering, bonding, and / or spraying processes can be used to form the interconnects. In some embodiments, a plurality of interconnects can be formed after each dielectric layer has been formed. Figures 24A-24C Stages 1-6 are illustrated and described as examples of forming a dielectric layer and multiple interconnects.
[0136] The method (at 2515) forms at least one bent antenna. Different implementations can result in different bent antenna designs and configurations. The bent antenna can be bent relative to the surface of at least one dielectric layer. At least a portion of the bent antenna is offset from the surface of at least one dielectric layer (e.g., vertically offset). Figure 19 , Figure 20 , Figures 21A-21B and Figures 22A-22B The illustrations and descriptions depict different examples of forming at least one curved antenna.
[0137] The method (at 2520) forms a solder resist layer (e.g., 822) over a dielectric layer (e.g., 802, 810). The solder resist layer can be formed using a deposition process. Figure 24D Stage 8 illustrates an example of forming a solder resist layer.
[0138] The method (at 2525) couples multiple solder interconnects (e.g., 840) to multiple interconnects (e.g., 830). A reflow process can be used to couple multiple solder interconnects to multiple interconnects. Figure 24D Phase 9 illustrates an example of solder interconnects coupled to the interconnects of an antenna device.
[0139] In some implementations, multiple antenna devices are formed on a wafer and / or carrier. In this case, the wafer or carrier is diced (e.g., monolithized, sliced) into multiple discrete antenna devices. The wafer or carrier can be diced using mechanical processes (e.g., sawing) and / or laser processes (e.g., laser ablation).

[0144] The term “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation or aspect described herein as “exemplary” is not necessarily to be construed as superior to or better than other aspects of this disclosure. Similarly, the term “aspect” does not require that all aspects of this disclosure include the features, advantages, or modes of operation discussed. The term “coupling” is used herein to refer to direct or indirect coupling between two objects (e.g., mechanical coupling). For example, if object A is in physical contact with object B, and object B is in contact with object C, then objects A and C can still be considered coupled to each other—even if they are not in direct physical contact. The term “electrical coupling” can mean that two objects are directly or indirectly coupled together so that current (e.g., signal, power, ground) can propagate between the two objects. Electrically coupled objects may or may not have current propagating between them. Electromagnetic coupling can mean that a signal from one circuit and / or component affects a signal from another circuit and / or component. Electromagnetic coupling can cause crosstalk. Electromagnetic coupling can be a form of signal coupling. The use of the terms “first,” “second,” “third,” and “fourth” (and / or anything greater than fourth) is arbitrary. Any component described may be a first component, a second component, a third component, or a fourth component. For example, a component referred to as the second component may be a first component, a second component, a third component, or a fourth component. The terms “top” and “bottom” are arbitrary. A component located at the top may be located on top of a component located at the bottom. A top component may be considered as a bottom component, and vice versa. The term “sealed” means that an object may partially or completely seal another object. Further note that the term “on top of” as used in this application in the context of one component being on top of another component may be used to mean a component on and / or in another component (e.g., on the surface of the component or embedded in the component). Thus, for example, a first component on top of a second component may mean (1) the first component is on top of the second component but does not directly contact the second component, (2) the first component is on the second component (e.g., on the surface of the second component), and / or (3) the first component is in (e.g., embedded in) the second component. The terms “approximately 'X value'” or “approximately X value” as used in this disclosure mean within 10% of the 'X value'. For example, a value of approximately 1 or close to 1 would mean a value in the range of 0.9-1.1.
[0145] In some embodiments, an interconnect is a device or packaged element or assembly that allows or facilitates an electrical connection between two points, elements, and / or components. In some embodiments, an interconnect may include traces, vias, pads, pillars, redistributed metal layers, and / or under-bump metallization (UBM) layers / interconnects. In some embodiments, an interconnect is a conductive material that can be configured to provide an electrical path for signals (e.g., data signals), ground, and / or power. An interconnect may be part of a circuit. An interconnect may include more than one element or assembly. An interconnect may be defined by one or more interconnects. Different embodiments may use different processes and / or sequences to form interconnects. In some embodiments, chemical vapor deposition (CVD), physical vapor deposition (PVD), sputtering, spraying, and / or plating processes may be used to form interconnects.
[0146] Furthermore, it should be noted that the various disclosures contained herein can be described as processes, depicted as flowcharts, diagrams, structural diagrams, or block diagrams. Although flowcharts can describe operations as sequential processes, many operations can be performed in parallel or simultaneously. Moreover, the order of operations can be rearranged. A process terminates when its operations are completed.
[0147] The various features of this disclosure described herein can be implemented in different systems without departing from this disclosure. It should be noted that the foregoing aspects of this disclosure are merely illustrative and should not be construed as limiting the scope of this disclosure. The descriptions of various aspects of this disclosure are intended to be illustrative and not to limit the scope of the claims. Therefore, this teaching can be readily applied to other types of devices, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
