Abstract
Description
[Technical Field]
[0001] The present invention relates to a semiconductor module, and more particularly to a semiconductor module that controls high power and dissipates heat generated by high power. More particularly, the present invention relates to a semiconductor module that combines a multilayer insulating substrate having a relatively thick metal pattern with a heat dissipation substrate to stably control high power and efficiently dissipate heat generated by the use of high power, thereby ensuring electrical and structural stability. [Background technology]
[0002] Generally, a semiconductor package is manufactured by mounting one or more semiconductor chips on a lead frame or a printed circuit board, sealing the chips with a sealing resin, and then mounting the chips on a motherboard or a printed circuit board.
[0003] On the other hand, as electronic devices become faster, have larger capacities, and are more highly integrated, there is a demand for smaller, lighter, and more multifunctional power elements to be used in electronic devices.
[0004] For this reason, a power module package has been proposed in which multiple power semiconductor chips and control semiconductor chips are integrated into a single semiconductor chip.
[0005] For example, as shown in FIG. 1, a power module package according to the prior art has a laminated structure of a first metal layer 11, a ceramic insulating layer 12, and a second metal layer 13, and the second metal layer 13 is generally a relatively thick metal layer having a thickness of 0.1 mm to 1.5 mm so that high power can be applied.
[0006] That is, the power semiconductor chip 14 is mounted on the second metal layer 13, and the control semiconductor chip 16, which has a relatively smaller mounting area than the power semiconductor chip 14, is mounted on the third metal layer 15 formed separately from the second metal layer 13. However, although the high temperature heat generated in the power semiconductor chip 14 during operation must be effectively dissipated, the heat cannot be dissipated efficiently due to the control semiconductor chip 16 arranged adjacent to it, and there are limitations in ensuring thermal stability or electrical stability.
[0007] Therefore, a technology is required that can design a PCB board and a heat dissipation board on which semiconductor components are mounted through an embedded semiconductor module structure, allowing for the application of high power through metal patterns and efficient heat dissipation.

[0041] Hereinafter, an embodiment of the present invention having the above-mentioned features will be described in more detail with reference to the accompanying drawings.
[0042] A semiconductor module according to an embodiment of the present invention includes a multilayer insulating substrate 110 which is composed of two or more metal layers 111 insulated from each other and an insertion groove 112 formed so that one or more first semiconductor components 120 can be inserted therein, and in which one or both sides of the one or more first semiconductor components 120 are electrically connected to the metal layer 111 via a bonding layer 113; an insulating material 130 which surrounds two or more sides of the first semiconductor components 120 within the insertion groove 112; heat dissipation substrates 140A, 140B which are electrically or structurally bonded to one or both sides of the one or more first semiconductor components 120; and one or more second semiconductor components 150 which are mounted on the top, bottom, or top and bottom sides of the multilayer insulating substrate 110; and the depth D of the insertion groove 112 is greater than the thickness T of the first semiconductor components 120, thereby enabling high power to be controlled and heat generated by high power to be dissipated.
[0043] The semiconductor module having the above-described configuration will be described in detail below with reference to FIGS.
[0044] First, referring to Figures 2, 3, 4 and 6, the multilayer insulating substrate 110 is composed of two or more metal layers 111, such as an upper metal layer 111a and a lower metal layer 111b, which are insulated from each other, an insulating layer 111c that insulates the two or more metal layers 111 from each other, and an insertion groove 112 formed so that one or more first semiconductor components 120 can be inserted.One or the other side of one or more first semiconductor components can be electrically connected to the surface of any one of the metal layers 111 via a bonding layer 113, so that an electrical signal can be applied.
[0045] Here, the thickness of the metal layer 111 is at least 0.2 mm, and the thickness T of each of the metal layers 111a, 111b is 0.1 mm or more, so that the first semiconductor component 120 or the second semiconductor component 150 can stably control high power, and each of the metal layers 111a, 111b can be electrically connected to two or more terminals of the first semiconductor component 120 or the second semiconductor component 150, and can be electrically connected to the source terminal, gate terminal and / or drain terminal.

[0065] Specifically, the thermal conductivity of the insulating layer 143 is preferably 2 W / mK to 30 W / mK.
[0066] 2, 3, 4 and 6, heat dissipation fins 147 of various shapes and structures such as cylindrical and polygonal pillars are protruded from the heat dissipation substrates 140A and 140B to enhance heat dissipation efficiency by air-cooling or water-cooling using air, refrigerant gas, refrigerant fluid, or cooling water, thereby expanding the heat dissipation area and improving heat dissipation efficiency.
[0067] Here, the heat dissipation fins 147 may be bonded to one surface of the heat dissipation substrates 140A and 140B using a metal or non-metal bonding agent 147a or may have a protruding structure bonded by ultrasonic bonding.
[0068] For example, the heat dissipation fins 147 may be integrally formed with the lower metal layer 142 of the heat dissipation substrates 140A and 140B, or may be bonded using a metallic or non-metallic adhesive 147a, or may be attached using ultrasonic waves without an adhesive.
[0069] 6, the heat dissipation device may further include a water jacket 160 that is structurally joined to the heat dissipation substrates 140A and 140B and includes an inlet, an outlet, and a flow path formed so that the heat dissipation fins 147 are exposed and come into contact with the refrigerant gas or the cooling water, so as to allow the refrigerant gas, the refrigerant fluid, or the cooling water to flow through the heat dissipation fins 147, thereby further improving heat dissipation efficiency and electrical stability.
[0070] Furthermore, as shown in Figures 2 and 3, in the first and second examples, a metal convex portion 170 is formed protruding from a portion of the surface of the upper metal layer 141 of the heat dissipation substrates 140A, 140B, for bonding to one or the other side of the first semiconductor component 120 via the bonding layer 144, thereby further increasing the attachment accuracy of the first semiconductor component 120 and further improving the bonding reliability compared to attaching the first semiconductor component 120 to a flat upper metal layer 141.
[0071] 6 and 7, metal posts 148 may be electrically and structurally bonded between one or the other surfaces of one or more first semiconductor components 120 and the opposing surfaces of heat dissipation substrates 140A and 140B via bonding layers 148a, thereby increasing thermal conductivity and improving heat dissipation efficiency.
[0072] Next, referring to FIGS. 2, 3, 4 and 6, one or more second semiconductor components 150 are configured and mounted on the top surface, bottom surface, or both the top and bottom surfaces of the multi-layer insulating substrate 110.
