[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application No. 2023233784419, filed on December 12, 2023, entitled “Semiconductor device and electronic device with heat dissipation structure,” which is incorporated herein by reference in its entirety. Technical Field
[0003] The present application relates to the field of semiconductor technology, and in particular to a semiconductor device and electronic equipment with a heat dissipation structure. Background Art
[0004] Currently, with the increasing integration of integrated circuits, higher requirements are being placed on semiconductor device heat dissipation technology. When heat cannot be effectively dissipated, the chip temperature of the semiconductor device increases, thereby reducing the device's power output and RF performance.
[0005] Semiconductor device heat dissipation technology relies solely on one-way heat conduction through the die-bonding material on the device, resulting in poor heat removal performance. Alternatively, heat dissipation relies on air cooling. However, in sealed spaces or compact structures (where airflow is low), it's difficult to lower the temperature of the semiconductor. Operating the chip at high temperatures for extended periods shortens its lifespan and performance stability.

[0034] A semiconductor device with a heat dissipation structure of the present application is described below with reference to Figures 1 and 2. The semiconductor device with a heat dissipation structure comprises: a semiconductor 1, a heat conducting component 2, and a heat dissipation component 3.
[0035] Among them, the first end of the thermal conductive component 2 is arranged adjacent to the first end surface of the semiconductor 1, and is used to transfer the heat of the semiconductor 1 to the thermal conductive component 2; one end of the heat dissipation component 3 is in thermal contact with the second end surface of the semiconductor 1, and the second end of the thermal conductive component 2 is in thermal contact with the heat dissipation component 3.
[0036] Specifically, semiconductor 1 is a heat-generating element, and heat is dissipated from semiconductor 1 by a heat-conducting assembly 2 and a heat-dissipating assembly 3 serving as a heat dissipation structure. Heat is dissipated from the second end face of semiconductor 1 by heat conduction through heat-dissipating assembly 3. Heat-conducting assembly 2 is in contact with or positioned adjacent to the first end face of semiconductor 1. When in contact, heat is transferred via conduction. When the heat-conducting assembly 2 and semiconductor 1 are positioned adjacent, heat is transferred via radiation by adjusting the distance between them. Heat from semiconductor 1 is transferred to heat-conducting assembly 2, which then dissipates it through heat-dissipating assembly 3.
[0037] Preferably, the first end face and the second end face of the semiconductor 1 in this embodiment are different end faces to be dissipated. As shown in Figure 1, the first end face and the second end face are the upper surface and the lower surface of the semiconductor 1, respectively. By utilizing the thermal conductive component 2, the heat from the upper surface of the semiconductor 1 is transferred to the heat dissipation component 3 for heat dissipation.
[0038] In this embodiment, the heat of the semiconductor 1 is transferred by the heat conducting component 2 and the heat dissipation component 3 is used for heat dissipation. On the one hand, the heat dissipation efficiency of the semiconductor 1 is improved to meet the heat dissipation needs of the semiconductor 1 when it is working; on the other hand, there is no need to use air cooling, which is suitable for scenarios where the semiconductor 1 needs to be cooled in a closed environment or a compact space.
[0039] The present application provides a semiconductor device with a heat dissipation structure, comprising: a semiconductor 1, a heat-conducting component 2, and a heat dissipation component 3. The first end of the heat-conducting component 2 is disposed adjacent to the first end face of the semiconductor 1 and is used to transfer heat from the semiconductor 1 to the heat-conducting component 2; one end of the heat dissipation component 3 is in thermal contact with the second end face of the semiconductor 1, and the second end of the heat-conducting component 2 is in thermal contact with the heat dissipation component 3. The present application transfers heat from the semiconductor 1 via the heat-conducting component 2 and dissipates heat via the heat dissipation component 3. This improves the heat dissipation efficiency of the semiconductor 1, meeting the heat dissipation needs of the semiconductor 1 during operation; and also eliminates the need for air cooling. The heat dissipation structure occupies a small space and is suitable for dissipating heat from the semiconductor 1 in a closed environment or a compact space.
[0040] In one embodiment of the present application, a first end of the thermally conductive component 2 is in thermal contact with a first end surface of the semiconductor 1. In this embodiment, heat is transferred between the thermally conductive component 2 and the semiconductor 1 by heat conduction. To ensure heat conduction efficiency, one end surface of the thermally conductive component 2 is in contact with the first end surface of the semiconductor 1.
[0041] On the basis of the above embodiment, the heat-conducting component 2 is a zigzag structure, and at least one end face of the heat-conducting component 2 is in contact with the first end face of the semiconductor 1, and at least one end face of the heat-conducting component 2 is in contact with the first end of the heat-dissipating component 3. Specifically, as shown in Figure 1, the heat-conducting component 2 adopts a heat-conducting plate with a zigzag structure, which has two upper and lower end faces and a vertical section. The upper and lower end faces are parallel and connected by the vertical section. The upper end face is in contact with the upper end face of the semiconductor 1 to achieve heat conduction; the lower end face is in contact with the heat-dissipating component 3 to achieve heat conduction. In this embodiment, the heat-conducting component 2 adopts a heat conduction method. On the one hand, it can cooperate with the heat-dissipating component 3 to dissipate heat from at least two end faces of the semiconductor 1, thereby enhancing the heat dissipation effect of the semiconductor 1; on the other hand, the heat-conducting component 2 adopting the zigzag structure can reduce the space occupied by the heat dissipation structure, which is suitable for semiconductor 1 heat dissipation scenarios in closed or narrow spaces.
[0042] In one embodiment of the present application, the heat dissipation component 3 includes: a column-type heat sink or a fin-type heat sink. It should be understood that, depending on actual conditions, the heat dissipation component 3 may also adopt other forms of heat sinks, and the present application is not limited thereto.
[0043] In one embodiment of the present application, a preset distance is set between the first end of the heat-conducting component 2 and the first end face of the semiconductor 1, and the semiconductor 1 transfers heat to the heat-conducting component 2 by thermal radiation. In this embodiment, the heat-conducting component 2 and the semiconductor 1 transfer heat by non-contact thermal radiation. This arrangement can ensure that the two are within the range of a safe insulation distance, thereby achieving heat dissipation of the semiconductor 1. The heat-conducting component 2 using thermal radiation can, on the one hand, cooperate with the heat dissipation component 3 to dissipate heat from at least two end faces of the semiconductor 1, thereby enhancing the heat dissipation effect of the semiconductor 1; on the other hand, the use of a non-contact heat dissipation method will not affect the normal operation of the semiconductor 1; on the other hand, instead of the air-cooled heat dissipation method, it can reduce the space occupied by the heat dissipation structure, which is suitable for semiconductor 1 heat dissipation scenarios in enclosed or narrow spaces.
[0044] Based on the above embodiment, the heat dissipation component 3 includes: a first heat dissipation unit 31 and a second heat dissipation unit 32. One end of the first heat dissipation unit 31 is in thermal contact with the second end surface of the semiconductor 1; one end of the second heat dissipation unit 32 is in thermal contact with the second end of the thermal conductive component 2. In this embodiment, the heat dissipation component 3 can be composed of two parts, namely the first heat dissipation unit 31 and the second heat dissipation unit 32. The first heat dissipation unit 31 is in direct contact with the second end surface of the semiconductor 1 and dissipates heat by heat conduction; the second heat dissipation unit 32 dissipates heat from the first end surface of the semiconductor 1 by heat radiation through the thermal conductive component 2. In this embodiment, two independent heat dissipation units are used to dissipate heat from the two surfaces of the semiconductor 1 respectively to improve its heat dissipation effect.
[0045] Based on the above embodiment, the first heat dissipation unit 31 includes a fin-type heat sink or a column-type heat sink, and the second heat dissipation unit 32 includes a fin-type heat sink or a column-type heat sink. It should be understood that, depending on actual conditions, the first heat dissipation unit 31 and the second heat dissipation unit 32 may also use other forms of heat sinks, and the present application is not limited thereto.
[0046] In one embodiment of the present application, the heat conducting component 2 includes a heat conducting sheet. It should be understood that, depending on the actual situation, the heat conducting component 2 may also adopt other forms of heat conducting parts, and the present application is not limited thereto.
[0047] In one embodiment of the present application, the semiconductor device 1 further includes a housing 4, wherein the semiconductor 1 and the thermally conductive component 2 are both disposed within the housing 4, and the heat dissipation end of the heat dissipation component 3 is disposed outside the housing 4. In this embodiment, the housing 4 serves as the outer shell of the semiconductor device 1, wherein the semiconductor 1 and the thermally conductive component 2 are both disposed within the housing 4, and the heat dissipation end of the heat dissipation component 3 is disposed outside the housing 4. Heat from the semiconductor 1 is dissipated outside the housing 4 through heat transfer between the thermally conductive component 2 and the heat dissipation component 3.
[0048] The present application also provides an electronic device, which includes: a semiconductor device with a heat dissipation structure according to an embodiment of the present application.
[0049] Furthermore, the electronic device provided by the present application has the same advantages as above because it includes the semiconductor device with the heat dissipation structure in the embodiment of the present application.
