Examples of the top portion and the foot portion (e.g., a foot) of lid structure 209 are described below at least in Figures 5 - 6It is further described in detail in []. The foot portion of the cover structure 209 is located above the peripheral portion of the substrate 102. The adhesive 106 is coupled to the foot portion of the cover structure 209 and the substrate 102. In some specific embodiments, the adhesive 106 may be coupled to the solder mask layer 126. In some specific embodiments, the adhesive 106 may be coupled to the dielectric layer of the substrate 102. The cover structure 209 may include metal. The cover structure 209 is configured to provide heat dissipation for the integrated device 103 through the thermal interface material 110.

The thermal interface material 110 may be coupled to the integrated device 103 and the cover structure 209. The thermal interface material 110 may be coupled to the back side and the side surface of the integrated device 103. The thermal interface material 110 may be coupled to the surface of the compartment 290 of the cover structure 209. For example, the thermal interface material 110 may be coupled to the side surface of the compartment 290 of the cover structure 109 (e.g., coupled to the side surface of at least one protrusion 292) and the inner top surface of the compartment 290. In some specific embodiments, a portion of the integrated device 103 may be located in the compartment 290 of the cover structure 209. The compartment 290 may include the thermal interface material 110 and a portion of the integrated device 103. In some specific embodiments, the integrated device 103 is the only integrated device and / or passive device located in the compartment 290. The side surface of the compartment 290 may laterally surround a portion of the integrated device 103 and / or the thermal interface material 110. For example, at least one protrusion 292 may only laterally surround a portion of the integrated device 103 and / or the thermal interface material 110. However, it should be noted that at least one protrusion 292 that only laterally surrounds a portion of the integrated device 103 and / or the thermal interface material 110 may laterally surround the gas (e.g., air) that may be present.
[0042] As will be further described below, the use of compartment 290 helps to improve the compression of the thermal interface material 110, which helps to reduce the thermal resistance of the thermal interface material 110 and helps to improve the heat transfer ability of the thermal interface material 110.
[0043] The coupling of the lid structure 209 to the substrate 102 can form another compartment 260. The compartment 260 can be a space defined at least by the lid structure 209 and the substrate 102. The integrated device 103, the passive device 105, and the passive device 107 can be located in the compartment 260 (e.g., can be located in a space defined at least by the lid structure 209 and the substrate 102).

[0044] Figure 3 An exemplary cross-sectional view of the lid structure 109 is illustrated. The lid structure 109 includes a feet portion 301 and a top portion 302. The lid structure 109 further includes a compartment 190. The compartment 190 is defined by an inner top surface 303 and an inner side surface 304 (e.g., side surface). The inner top surface 303 and the inner side surface 304 can be located in the top portion 302 of the lid structure 109. The compartment 190 (e.g., the first compartment) can include a cavity defined by the inner top surface 303 and the inner side surface 304 of the lid structure 109. Figure 3 The compartment 194 is also illustrated. The compartment 194 (e.g., the second compartment) can be a space defined by at least the feet portion 301 (e.g., feet) of the lid structure 109. The compartment 190 can be located above the compartment 194. The compartment 190 can be configured to include a thermal interface material (e.g., 110) such that the thermal interface material is coupled to the inner top surface 303 and the inner side surface 304.
[0045] The use of the compartment 190 helps to improve the compression of the thermal interface material 110, which helps to reduce the thermal resistance of the thermal interface material 110 and helps to improve the heat transfer ability of the thermal interface material 110. For example, the inner side surface 304 helps to provide additional compression on the thermal interface material between the integrated device (e.g., 103) and the lid structure 109, which helps to reduce the thermal resistance of the thermal interface material and helps to increase the heat transfer ability of the thermal interface material between the integrated device and the lid structure.
[0046] Figure 4 An exemplary perspective view of the lid structure 109 is illustrated. Figure 4 The lid structure 109 is illustrated from a bottom corner and / or an inner corner. The lid structure 109 includes a compartment 190 and a compartment 194. The compartment 194 can correspond to and / or be similar to the compartment 160.
[0047] Figure 5An exemplary cross-sectional view of the lid structure 209 is illustrated. The lid structure 209 includes a foot portion 501 and a top portion 502. The lid structure 209 includes at least one protrusion 292. The at least one protrusion 292 can be at least one protrusion extending from the top portion 502. The at least one protrusion 292 can be considered a part of the top portion 502. The lid structure 209 further includes a compartment 290. The compartment 290 is defined by an inner top surface 503 and an inner side surface 504 (e.g., a side surface). The inner top surface 503 can be a part of the top portion. The inner side surface 504 can be the side surface of the at least one protrusion 292. Figure 5 A compartment 294 is also illustrated. The compartment 294 (e.g., a second compartment) can be a space defined by at least the foot portion 501 (e.g., the foot) of the lid structure 209. The compartment 290 can be located above the compartment 294. The compartment 290 can be configured to include a thermal interface material (e.g., 110) such that the thermal interface material is coupled to the inner top surface 503 and the inner side surface 504.
[0048] The use of the compartment 290 helps to improve the compression of the thermal interface material 110, which helps to reduce the thermal resistance of the thermal interface material 110 and helps to improve the heat transfer ability of the thermal interface material 110. For example, the inner side surface 504 of the at least one protrusion 292 helps to provide additional compression on the thermal interface material between the integrated device (e.g., 103) and the lid structure 209, which helps to reduce the thermal resistance of the thermal interface material and helps to increase the heat transfer ability of the thermal interface material between the integrated device and the lid structure.
[0049] Figure 6 An exemplary perspective view of the lid structure 209 is illustrated. Figure 6 The lid structure 209 is illustrated from a bottom corner and / or an inner corner. The lid structure 209 includes a compartment 290, at least one protrusion 292, and a compartment 294. The compartment 294 can correspond to and / or be similar to the compartment 260.
[0050] Figure 7 An exemplary junction temperature map distribution of an integrated device coupled to the lid structure without a cavity is illustrated. The junction temperature map distribution 700 illustrates an exemplary temperature on the front side of the integrated device 103. The junction temperature map distribution 700 illustrates a spot 703 on the integrated device 103, which can be a hot spot.
[0051] Figure 8Illustrates an exemplary junction temperature map distribution of an integrated device coupled to a lid structure having a cavity, such as lid structure 109. The junction temperature map distribution 800 illustrates exemplary temperatures on the front side of the integrated device 103. The junction temperature map distribution 800 also illustrates a spot 703 on the integrated device 103. The junction temperature map distribution 800 illustrates that the spot 703 is less hot (compared to the spot 703 on the junction temperature map distribution 700). The reduction in the temperature of the spot 703 may be due to the improved heat dissipation ability by using the lid structure 109 (or lid structure 209). Note that Figure 7 and Figure 8 the temperature map distributions are exemplary. Different specific implementations may have different temperature map distributions.
[0052] Figure 9 Illustrates an exemplary stress map distribution of a quadrant of a thermal interface material coupled to an integrated device and a lid structure without a cavity. The stress map distribution 900 illustrates exemplary stresses on the thermal interface material (e.g., 110) coupled to the back side of the integrated device 103. The stresses may include compressive stresses (e.g., compressive stress) and tensile stresses (e.g., tensile stress). Compressive stresses may be represented as negative values in the stress map distribution 900, while tensile stresses may be represented as positive values in the stress map distribution 900. As shown in the stress map distribution 900, there are compressive stresses near the center of the integrated device 103 and tensile stresses (or less compressive stresses) near the edges of the integrated device 103. The stress map distribution 900 illustrates a spot 903 on the thermal interface material 110 near the center of the integrated device 103.
[0053] Figure 10 Illustrates an exemplary stress map distribution of a thermal interface material coupled to an integrated device and a lid structure having a cavity, such as lid structure 109. The stress map distribution 1000 illustrates exemplary stresses on the thermal interface material (e.g., 110) coupled to the back side of the integrated device 103. The stresses may include compressive stresses (e.g., compressive stress) and tensile stresses (e.g., tensile stress). Compressive stresses may be represented as negative values in the stress map distribution 1000, while tensile stresses may be represented as positive values in the stress map distribution 1000. The stress map distribution 1000 illustrates a spot 903 on the thermal interface material 110 near the center of the integrated device 103. The inner surface of the lid structure helps to increase the compression of the thermal interface material between the integrated device 103 and the lid structure 109, which helps to reduce the thermal resistance of the thermal interface material and helps to increase the heat transfer ability of the thermal interface material. Figure 9 and Figure 10 Illustrates that when using a lid structure having a cavity and / or compartment, the spot 903 has greater compression of the thermal interface material, as at least in Figures 1 - 2As described. This compression increase near and / or around the center of the integrated device (and throughout the integrated device) helps to improve the heat transfer ability of the thermal interface material, which in turn helps to improve heat dissipation from the integrated device to the cover structure. Note that Figure 9 and Figure 10 The stress map distributions are exemplary. Different specific implementations may have different stress map distributions.
[0054] An integrated device (e.g., 103) may include a die (e.g., a semiconductor bare die). The integrated device may include a power management integrated circuit (PMIC). The integrated device may include an application processor. The integrated device may include a modem. The integrated device may include radio frequency (RF) devices, passive devices, filters, capacitors, inductors, antennas, transmitters, receivers, gallium arsenide (GaAs)-based integrated devices, 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, memories, power management processors, and / or combinations thereof. An integrated device (e.g., 103, 105, 107) may include at least one electronic circuit (e.g., a first electronic circuit, a second electronic circuit, etc.). The integrated device may include transistors. The integrated device may be an example of an electrical component and / or an electrical device. In some particular implementations, the integrated device may be a chiplet. Chiplets may be manufactured using a process that provides better yield compared to other processes used to manufacture other types of integrated devices, which may reduce the overall cost of manufacturing chiplets. Different chiplets may have different sizes and / or shapes. Different chiplets may be configured to provide different functions. Different chiplets may have different interconnect densities (e.g., interconnects having different widths and / or pitches). In some particular implementations, a number of chiplets may be used to perform the functionality of one or more chips (e.g., one or more integrated devices). Thus, for example, a single integrated device may be divided into a number of chiplets. As described above, using a number of chiplets that perform a number of functions may reduce the overall cost of a package compared to using a single chip to perform all the functions of the package. In some particular implementations, one or more chiplets and / or one or more integrated devices (e.g., 103) described in the present disclosure may be manufactured using the same technology node or two or more different technology nodes. For example, an integrated device may be manufactured using a first technology node, and a chiplet may be manufactured using a second technology node that is less advanced than the first technology node. In such examples, the integrated device may include components (e.g., interconnects, transistors) having a first minimum size, and the chiplet may include components (e.g., interconnects, transistors) having a second minimum size, where the second minimum size is greater than the first minimum size. In some particular implementations, the same technology node or different technology nodes may be used to manufacture one integrated device and another integrated device of a package. In some particular implementations, the same technology node or different technology nodes may be used to manufacture one chiplet and another chiplet of a package.

[0077] The term "exemplary" is used herein to mean "serving as an example, instance, or illustration". Any particular implementation or aspect described herein as "exemplary" is not necessarily to be construed as superior to or better than other aspects of the disclosure. Similarly, the term "aspect" does not require that all aspects of the disclosure include the recited features, advantages, or modes of operation. The term "coupled" is used herein to refer to a direct or indirect coupling (e.g., a mechanical coupling) between two objects. For example, if object A physically contacts object B and object B contacts object C, then objects A and C may still be considered to be coupled to each other even if they do not directly physically contact each other. An object A that is coupled to object B may be coupled to at least a portion of object B. The term "electrically coupled" may mean that two objects are directly or indirectly coupled together such that an electric current (e.g., a signal, power, ground) can be passed between the two objects. Two objects that are electrically coupled may or may not have an electric current flowing between the two objects.

The terms "enclose", "enclosing", and / or any derivatives thereof mean that an object may partially enclose or fully enclose another object. The terms "top" and "bottom" are arbitrary. A component located at the top may be above a component located at the bottom. A top component may be considered a bottom component and vice versa. As described in the disclosure, a first component located "above" a second component may mean that the first component is located above or below the second component, depending on how the bottom or top is arbitrarily defined. In another example, a first component may be above (e.g., on top of) a first surface of the second component, while a third component may be above (e.g., below) a second surface of the second component, where the second surface is opposite the first surface. It should also be noted that the term "above" as used in the context of one component being on another component in this application may be used to mean that the component is 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 above the second component may mean: (1) the first component is above the second component but does not directly contact the second component; (2) the first component is above (e.g., on the surface of) the second component; and / or (3) the first component is in (e.g., embedded in) the second component. A first component located "in" a second component may be partially located in the second component or fully located in the second component. A value of about X to XX may refer to a value between X and XX, including X and XX. The values between X and XX may be discrete or continuous. As used in the disclosure, the term "about 'value X'" or "substantially value X" means within 10 percent of "value X".For example, a value of about 1 or approximately 1 will mean a value in the range of 0.9 to 1.1.
