ID Similarly, the plurality of solder interconnects 106 may include an integrated device bump solder pitch P ID In addition, the plurality of solder interconnects 190 may include a solder bump having an integrated passive device solder pitch P. IPDS In some implementations, the pitch between adjacent column interconnects (eg, 105a, 105b) may be P CI In some implementations, the pitch between adjacent column interconnects (e.g., 105a, 105b) is approximately the same as the pitch between adjacent solder interconnects (e.g., 106a, 106b) coupled to adjacent column interconnects (e.g., 105a, 105b). In some implementations, the pitch between adjacent column interconnects (e.g., 105a, 105b) is approximately the same as the pitch between adjacent solder pillar interconnects (e.g., 104a, 104b) coupled to adjacent column interconnects (e.g., 105a, 105b) through adjacent solder interconnects (e.g., 106a, 106b). In some implementations, the pitch between adjacent column interconnects (e.g., 105a, 105b) is approximately the same as the pitch between adjacent solder interconnects (e.g., 190a, 190b) coupled to adjacent column interconnects (e.g., 105a, 105b).
[0033] In some implementations, a pair of pad interconnects on a particular metal layer (e.g., M1, M2, M3, M4) from the first column interconnect 105a and the second column interconnect 105b may have approximately the same pitch as another pair of pad interconnects on another metal layer (e.g., M1, M2, M3, M4) from the first column interconnect 105a and the second column interconnect 105b. For example, in some implementations, the pitch between interconnect 122aa and interconnect 122ba is approximately the same as the pitch between interconnect 122ac and interconnect 122bc. In some implementations, the pitch between interconnect 122aa and interconnect 122ba is approximately the same as the pitch between interconnect 122ae and interconnect 122be. In some implementations, the pitch between interconnect 122aa and interconnect 122ba is approximately the same as the pitch between interconnect 122ag and interconnect 122bg.
[0034] In some implementations, a pair of through-hole interconnects between two specific metal layers from the first column interconnect 105a and the second column interconnect 105b may have approximately the same pitch as another pair of through-hole interconnects between two other metal layers from the first column interconnect 105a and the second column interconnect 105b. For example, in some implementations, the pitch between interconnect 122ab and interconnect 122bb is approximately the same as the pitch between interconnect 122ad and interconnect 122bd. In some implementations, the pitch between interconnect 122ab and interconnect 122bb is approximately the same as the pitch between interconnect 122af and interconnect 122bf.
[0035] In some implementations, a pair of pad interconnects on a particular metal layer from the first column interconnect 105a and the second column interconnect 105b may have approximately the same pitch as a pair of via interconnects between two metal layers from the first column interconnect 105a and the second column interconnect 105b.

In some implementations, the pitch between interconnect 122ae and interconnect 122be is approximately the same as the pitch between interconnect 122af and interconnect 122bf.
[0036] Using dielectric layers with different materials for different layers helps provide interconnects with smaller spacing and / or smaller pitches, thereby allowing higher density interconnects, shorter electrical paths for current and / or signals, which may lead to improved performance of integrated devices and packages. In addition, using different dielectric materials between two other dielectric layers will not significantly affect the overall warpage of the substrate, thereby providing a substrate with reliable interconnects.
[0037] In some implementations, the pad interconnects (e.g., 122aa, 122ac, 122ae, 122ag, 122ba, 122bc, 122be, 122bg) from the first column interconnect 105a and / or the second column interconnect 105b may each have a minimum width and / or minimum diameter of about 90 microns. In some implementations, the first dielectric layer 120 may have a minimum thickness (T1) of about 20 microns. In some implementations, the second dielectric layer 130 may have a minimum thickness (T2) of about 15 microns. In some implementations, the third dielectric layer 140 may have a minimum thickness (T3) of about 20 microns. Thus, in some implementations, the thickness (T2) of the second dielectric layer 130 may be thinner than the thickness (T1) of the first dielectric layer 120 and / or the thickness (T3) of the third dielectric layer 140.
[0038] In some implementations, the through-hole interconnects (e.g., 122ab, 122af, 122bb, 122bf) from the first column interconnect 105a and / or the second column interconnect 105b located in the first dielectric layer 120 and / or the third dielectric layer 140 may each have a minimum width and / or minimum diameter of about 60 microns at its widest portion. In some implementations, the through-hole interconnects (e.g., 122ad, 122bd) from the first column interconnect 105a and / or the second column interconnect 105b located in the second dielectric layer 130 may each have a minimum width and / or minimum diameter of about 50 microns at its widest portion. In some implementations, the above configuration using different dielectric layers between the two dielectric layers helps to provide each interconnect pair from adjacent column interconnects on the same metal layer to have similar or identical spacing (S). I ).
[0039] In some implementations, the first column interconnect 105a is configured to provide an electrical path for power between the integrated device and the passive device. In some implementations, the second column interconnect 105b is configured to provide an electrical path for ground between the integrated device and the passive device. The passive device may include a capacitor (e.g., a discrete inductor). The passive device may include a decoupling capacitor configured to couple to a power source and / or a power distribution network.
[0040] Notice that Figure 1 A substrate including four metal layers is illustrated. However, other implementations may include substrates having more than four metal layers.

In some implementations, several core particles 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 several chiplets. As mentioned, the use of several core particles that perform several functions may reduce the overall cost of the package relative to using a single chip to perform all functions of the package. In some implementations, one or more core particles and / or one or more integrated devices (e.g., 202) 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 (e.g., 202) may be manufactured using a first technology node, and a core particle may be manufactured using a second technology node that is not as advanced as the first technology node. In this example, the integrated device (e.g., 202) may include a component (e.g., an interconnect, a transistor) having a first minimum size, and the core particle may include a component (e.g., an interconnect, a transistor) having a second minimum size, wherein the second minimum size is greater than the first minimum size. In some implementations, the packaged integrated device and the other integrated device may be manufactured using the same technology node or different technology nodes. In some implementations, the packaged die and the other die may be manufactured using the same technology node or different technology nodes.

[0113] Note that the drawings in this disclosure may represent actual representations and / or conceptual representations of various parts, assemblies, objects, devices, packages, integrated devices, integrated circuits, and / or transistors. In some instances, the drawings may not be to scale. In some instances, for clarity, not all components and / or parts are shown. In some instances, the positioning, location, size, and / or shape of the various components and / or assemblies in the drawings may be exemplary. In some implementations, the various components and / or parts in the drawings may be optional.
[0114] The wording "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 interpreted as superior or superior to other aspects of the present disclosure. Likewise, the term "aspect" does not require that all aspects of the present disclosure include the discussed features, advantages, or modes of operation. The term "coupled" is used herein to refer to a direct or indirect coupling (e.g., mechanical coupling) between two objects. For example, if object A physically contacts object B, and object B contacts object C, objects A and C can still be considered to be coupled to each other - even if they are not in direct physical contact with each other. Object A 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 so that an electric current (e.g., signal, power, ground) can be transferred between the two objects. Two electrically coupled objects may or may not have an electric current transfer between the two objects. The use of the terms "first", "second", "third", and "fourth" (and / or anything higher than the fourth) is arbitrary. Any component described may be a first component, a second component, a third component, or a fourth component. For example, the component referred to as the second component may be the first component, the second component, the third component, or the fourth component. The terms "encapsulate", "encapsulate" and / or any derivatives thereof refer to an object that may partially encapsulate or completely encapsulate another object. The terms "top" and "bottom" are arbitrary. A component located at the top may be located above a component located at the bottom. A top component may be considered a bottom component, and vice versa. As described in the present 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 located above (e.g., above) a first surface of a second component, and a third component may be located above (e.g., below) a second surface of the second component, wherein the second surface is opposite to the first surface. It is further noted that the term "above" as used in the context of a component being located above another component in the present application may be used to indicate that a component is on and / or in another component (e.g., on the surface of a component or embedded in a component). Thus, for example, a first component being above a second component may mean: (1) the first component is above the second component, but not directly contacting 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 the second component (e.g., embedded in the second component). A first component that is "in" a second component may be partially in the second component or completely in the second component. A value of about X-XX may mean a value between X and XX (inclusive). The value(s) between X and XX may be discrete or continuous. As used in the present disclosure, the term "about 'value X'" or "approximately value X" means within ten percent of 'value X'.For example, a value of about 1 or approximately 1 would mean a value in the range of 0.9-1.1.
[0115] In some implementations, interconnection is an element or component that allows or facilitates electrical connection between two points, elements and / or components in a device or package. In some implementations, interconnection may include traces, through holes, pads, pillars, metallization layers, redistribution layers, and / or under bump metallization (UBM) layers / interconnections. In some implementations, interconnection may include conductive materials that can be configured to provide electrical paths for signals (e.g., data signals), grounding, and / or power supplies. Interconnection may include more than one element or component. Interconnection may be defined by one or more interconnections. Interconnection may include one or more metal layers. Interconnection may be part of a circuit. Different implementations may use different processes and / or procedures to form interconnection. In some implementations, chemical vapor deposition (CVD) processes, physical vapor deposition (PVD) processes, sputtering processes, spraying, and / or electroplating processes may be used to form interconnection.
[0116] It should also be noted that the various disclosures contained herein may be described as processes depicted as flow charts, flow diagrams, structure diagrams, or block diagrams. Although a flow chart may describe an operation as a sequential process, many operations may be performed in parallel or concurrently. In addition, the order of the operations may be rearranged.
