Abstract
Description
Technical Field
[0001] The present disclosure generally relates to an electronic device. Background Art
[0002] For high performance computing (HPC) systems of electronic devices, power supply units with low power consumption and high heat dissipation are required. The power delivery path for transmitting power signals is usually provided by a system board on which several dies are mounted. The layout design may be limited by the need to minimize electromagnetic interference between power signals and non-power signals (e.g., electrical signals), which can limit the ability to miniaturize the system board.
[0003] The voltage and power requirements of the die vary, and the rapid increase in the total number and variety of dies has led to a corresponding increase in the number of power delivery paths. One approach to providing a more stable power delivery path is to provide power through an interconnect structure or power conditioning components on the interconnect die. However, this may increase the size of the electronic device and place further constraints on the level of miniaturization of the electronic device that can be achieved. Summary of the invention
[0004] In some embodiments, an electronic device includes a first electronic component, a second electronic component, and a circuit structure. The circuit structure is supported by the first electronic component and the second electronic component. The circuit structure electrically connects the first electronic component to the second electronic component and is configured to provide power to the first electronic component and the second electronic component.
[0005] In some embodiments, the electronic device includes a first electronic component, an interconnection circuit, and a second electronic component. The interconnection circuit is adjacent to the first electronic component. The second electronic component has a front surface for transmitting a non-power signal and a back surface for receiving a first power signal. The second electronic component is electrically connected to the first electronic component through the back surface of the second electronic component and the interconnection circuit.
[0006] In some embodiments, an electronic device includes a first electronic component and an integrated circuit. The first electronic component has a front surface and a back surface opposite to the front surface. The integrated circuit is configured to provide a power signal to the first electronic component through the back surface of the first electronic component, and is configured to bridge a non-power signal between the first electronic component and a second electronic component.

In some embodiments, the semiconductor die 30 may be connected to the electronic components 20-1 to 20-3 by solder bonding, conductive pillars (e.g., copper pillars), or a combination thereof. In some embodiments, the semiconductor die 30 may include a circuit structure configured to transmit and / or receive power signals and / or non-power signals. In some embodiments, the semiconductor die 30 may serve as an insert included in a signal path or a power path. In some embodiments, the semiconductor die 30 may be configured to provide power to the electronic components 20-1, 20-2, and 20-3. In some embodiments, the semiconductor die 30 may be configured to electrically connect the electronic components 20-1, 20-2, and / or 20-3. The semiconductor die 30 may include a surface 30s1 (or a lower surface or a front surface), a surface 30s2 (or an upper surface of the backside surface) opposite to the surface 30s1, and a surface 30s3 (or a lateral surface) extending between the surface 30s1 and the surface 30s2. In some embodiments, the surface 30s1 of the semiconductor die 30 may be configured to transmit power to the electronic components 20-1, 20-2, and 20-3.

In some embodiments, the power conditioning circuit 32a-1 may be located directly above the electronic component 20-1, which may reduce the transmission path of the power. Therefore, the voltage drop or power loss of the power path may be reduced. Figure 1B Although not shown and described, the structures and functions of the power conditioning circuits 32a-4 to 32a-10 may be the same as or similar to those of the power conditioning circuit 32a-1.
[0026] Circuit area 32 may include interconnect circuits 32b-1 and 32b-2.

Although Figure 1B Although not shown and described, the structures and functions of the interconnection circuits 32b-3 to 32b-7 may be the same as or similar to those of the interconnection circuit 32b-1.
[0027] In some embodiments, the rigid region 34 is closer to the surface 30s2 than the circuit region 32. In some embodiments, the rigid region 34 may be configured to support the circuit region 32. In some embodiments, the rigid region 34 may be more robust than the circuit region 32 because the structure of the semiconductor substrate of the rigid region 34 is less damaged than the circuit region 32. In some embodiments, the rigidity of the rigid region 34 may be greater than the rigidity of the circuit region 32. In some embodiments, the ratio of silicon (or components of the semiconductor substrate of the semiconductor die 30, such as semiconductor materials) of the rigid region 34 may be greater than the ratio of silicon of the circuit region 32. In some embodiments, the density of conductive elements (e.g., conductive layers, conductive traces, conductive pads, and / or conductive vias) of the rigid region 34 is less than the density of conductive elements (e.g., conductive layers, conductive traces, conductive pads, and / or conductive vias) of the circuit region 32. In some embodiments, no conductive elements (e.g., conductive layers, conductive traces, conductive pads, and / or conductive vias) are formed in the rigid region 34. In some embodiments, the thickness of the rigid region 34 may be greater than, equal to, or less than the thickness of the circuit region 32.
[0028] In some embodiments, the encapsulant 40 may be disposed on or above the surface 10s2 of the carrier 10.

[0029] like Figure 1B As shown, semiconductor die 30 may be configured to provide path P1. Path P1 may be a non-power path. In some embodiments, path P1 may pass through the backside surfaces of electronic components 20-1 to 20-6 and interconnect circuits 32b-1 to 32b-7. For example, path P1 may pass through surface 20-1s2 of electronic component 20-1, interconnect circuit 32b-1, and surface 20-2s2 of electronic component 20-2.
[0030] The semiconductor die 30 may be configured to provide a path P2. Path P2 may be a power path. In some embodiments, path P2 may pass through the backside surface of the electronic components 20-1 to 20-6 and the power conditioning circuits 32a-1 to 32a-10. For example, path P2 may pass through the power conditioning circuit 32a-1, the surface 30s1 of the semiconductor die 30, and the surface 20-1s2 of the electronic component 20-1. The semiconductor die 30 may be configured to provide a path P2'. Path P2' may be a power path. In some embodiments, path P2' may pass through the backside surface of the electronic components 20-1 to 20-6 and the power conditioning circuits 32a-1 to 32a-10. For example, path P2' may pass through the power conditioning circuit 32a-2, the surface 30s1 of the semiconductor die 30, and the surface 20-2s2 of the electronic component 20-2. In some embodiments, the power of path P2 may be the same as the power of path P2'. In some embodiments, the power of path P2 may be different from the power of path P2'.

[0032] In a comparative example, the power conditioning circuit (or component) is mounted on a power board or on an interconnection die. Such a design may increase the size (e.g., thickness) of the electronic device and increase the transmission path of the power path. In this embodiment, the power conditioning circuit and the interconnection circuit are integrated in the semiconductor die, which may reduce the size (e.g., thickness) of the electronic device. In addition, the power path may also be reduced to reduce voltage drop and / or power loss.
