CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the priority of Korean Patent Application No. 10-2012-0068102 filed on Jun. 25, 2012, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to a semiconductor package module, and more particularly, to a semiconductor package module constituted by modularizing power semiconductor devices incapable of being easily integrated due to heat generated therefrom. 
         [0004]    2. Description of the Related Art 
         [0005]    Recently, demand for portable electronic products is remarkably increasing, and in order to satisfy the demand, the miniaturization and weight reduction of electronic components mounted in the portable electronic products are required. 
         [0006]    Thus, when a semiconductor package is designed, a method of installing as many components and wirings as possible in a predetermined space therein, as well as a method of reducing the size of electronic components becomes more important. 
         [0007]    A power semiconductor device generates a large amount of heat while being driven. Since such high-temperature heat affects the lifespan and operation of an electronic product, it is also important to overcome a heat problem in a semiconductor package. 
         [0008]    To this end, a conventional power semiconductor package uses a structure in which both a power device and a control device are mounted on one surface of a circuit substrate, and a heat sink for emitting heat is disposed on the other surface thereof . 
         [0009]    However, a conventional power semiconductor package may have the following problems. 
         [0010]    Due to demand for miniaturized packages, the number of semiconductor devices disposed in a limited space is increased, and thus, a large amount of heat may be generated from an inside of a package. In this case, heat may not be effectively dissipated only via a heat sink disposed below the package. 
         [0011]    In addition, a conventional semiconductor package module mainly has a structure in which a plurality of semiconductor packages are coupled to a single heat sink. Thus, conventionally, when an error arises in any one of a plurality of semiconductor packages constituting a semiconductor package module, since it is impossible to only replace the semiconductor package in which the error has arisen, the semiconductor package module itself needs to be replaced.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0044]    Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the shapes and dimensions of elements may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like elements. 
         [0045]    Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
         [0046]      FIG. 1  is a schematic perspective view of a semiconductor package module according to an embodiment of the present invention. 
         [0047]    Referring to  FIG. 1 , a semiconductor package module  1  according to the present embodiment may include at least one semiconductor package  100 , a heat dissipation member  90 , substrates  80 , and a bus bar  30 . 
         [0048]    The semiconductor package  100  may be a power semiconductor package including a power semiconductor device to provide power. 
         [0049]      FIG. 2  is a schematic perspective view of the semiconductor package shown in  FIG. 1 .  FIG. 3  is a penetrating perspective view of the semiconductor package shown in  FIG. 2 .  FIG. 4  is a cross-sectional view of the semiconductor package  100  taken along line A-A′ of  FIG. 2 . 
         [0050]    Referring to  FIGS. 2 through 4 , the semiconductor package  100  according to the present embodiment may include an electronic device  10 , an external connection terminal  20 , abase substrate  60 , and a molding part  70 . 
         [0051]    The electronic device  10  may include various devices such as a passive device, an active device, and the like. In particular, the electronic device  10  according to the present embodiment may include a first electronic device  12  (e.g., a power semiconductor device) and a second electronic device  14  (e.g., a diode device). In this case, the first electronic device  12  as a power semiconductor device (hereinafter, referred to as “a power semiconductor device  12 ”) may be an insulated-gate bipolar transistor (IGBT) and the second electronic device  14  as a diode (hereinafter, referred to as “a diode device  14 ”) may be a fast recovery diode (FRD). 
         [0052]    That is, the semiconductor package  100  according to the present embodiment may be a power semiconductor package including the power semiconductor device  12  and the diode device  14  connected between a current input electrode and a current output electrode of the power semiconductor device  12 . However, the present invention is not limited thereto. 
         [0053]    In addition, a plurality of electrodes may be formed on the respective power semiconductor device and diode device of the electronic device  10  according to the present embodiment. 
         [0054]    In detail, a gate electrode  12   a  and an emitter electrode  12   b  may be formed on one surface of the power semiconductor device  12  and a collector electrode  12   c  may be formed on the other surface of the power semiconductor device  12 . In addition, a cathode electrode  14   a  may be formed on a surface of the diode device  14  and an anode electrode  14   b  maybe formed on the other surface of the diode device  14 . 
         [0055]    In particular, the power semiconductor device and diode device of the electronic device  10  according to the present embodiment are stacked on each other. That is, in the semiconductor package  100  according to the present embodiment, the power semiconductor device  12  and the diode device  14  of the electronic device  10  may be stacked on each other in such a manner that a surface of the diode device  14  faces the other surface of the power semiconductor device  12 , rather than being disposed on the same plane. 
         [0056]    In this case, the power semiconductor device  12  and the diode device  14  are respectively coupled to two surfaces of a common connection terminal  28 , a collector connection terminal, to be stacked each other. 
         [0057]    The external connection terminal  20  may include a plurality of external connection terminals each formed of a flat metal plate. Thus, the plurality of external connection terminals  20  according to the present embodiment may surface-contact two surfaces of the power semiconductor device  12  and the diode device  14  of the electronic device  10  and may be bonded to the electrodes  12   a  to  12   c  and  14   a  to  14   b  of the electronic device  10 . 
         [0058]    The external connection terminals  20  according to the present embodiment may be first, second, and third connection terminals  22 ,  24 , and  26  that are separate connection terminals, and the common connection terminal  28 . In this case, the first connection terminal  22  may be a gate connection terminal that is connected to the gate electrode  12   a.  The second connection terminal  24  may be an emitter connection terminal connected to the emitter electrode  12   b.  The third connection terminal  26  may be an anode connection terminal connected to the anode electrode  14   b.  In addition, the common connection terminal  28  may be a collector connection terminal connected to the collector electrode  12   c.    
         [0059]    One surface of the common connection terminal  28  is bonded to the collector electrode  12   c  of the power semiconductor device  12 . The other surface of the common connection terminal  28  is bonded to the cathode electrode  14   a  of the diode device  14 . That is, the common connection terminal  28  is interposed and bonded between the power semiconductor device  12  and the diode device  14 . 
         [0060]    Thus, the collector electrode  12   c  of the power semiconductor device  12  and the cathode electrode  14   a  of the diode device  14  may be electrically connected to each other via the common connection terminal  28 , and may share the common connection terminal  28  to be electrically connected to an external device. 
         [0061]    The external connection terminals  20  each have a flat plate shape and may be arranged to be parallel to each other. In addition, as shown in  FIG. 3 , the present embodiment illustrates a case in which the common connection terminal  28  and the first, second, and third connection terminals  22 ,  24 , and  26  are arranged to protrude in different directions (e.g., opposite directions). However, the present invention is not limited thereto. For example, the common connection terminal  28  and the first, second, and third connection terminals  22 ,  24 , and  26  may protrude in the same direction. Likewise, the common connection terminal  28  and the first, second, and third connection terminals  22 ,  24 , and  26  each having a flat plate shape maybe arranged in the various forms if necessary as long as they may surface-contact the power semiconductor device  12  and the diode device  14  of the electronic device  10 , to be boned thereto. 
         [0062]    The external connection terminal  20  may be formed of, but is not limited to, a material, such as copper (Cu), aluminum (Al), or the like. 
         [0063]    The base substrate  60  is disposed in at least one side of the outside of the first, second, and third connection terminals  22 ,  24 , and  26  and dissipates heat generated from the electronic device  10  outwardly. 
         [0064]    The base substrate  60  may be formed of a metal material in order to effectively dissipate heat to the outside. In this case, the base substrate  60  may be formed of Al or an Al alloy, which is relatively inexpensive, is easily used, and also has excellent thermal conductivity. However, the present invention is not limited thereto. The base substrate  60  may be formed of various kinds of material having excellent thermal conductivity, such as graphite or the like, other than metal. 
         [0065]    In the semiconductor package  100  according to the present embodiment, in order to prevent short circuits due to electrical connections between the base substrate  60  and the external connection terminals  20 , an insulating layer  65  may be interposed between the base substrate  60  and the external connection terminals  20 . 
         [0066]    The insulating layer  65  may be formed of various kinds of material, as long as the material may have high thermal conductivity, allow for firmly bonding and fixing of the base substrate  60  and the external connection terminals  20 , and electrically insulate the base substrates  60  and the external connection terminals  20  from each other. For example, the insulating layer  65  maybe formed of an insulating adhesive such as an epoxy resin or the like. However, the present invention is not limited thereto. 
         [0067]    The molding part  70  is formed to partially cover and seal the electronic device  10  and the external connection terminals  20  bonded to the electronic device  10  to protect the electronic device  10  from an external environment. In addition, the molding part  70  may surround an outer surface of the electronic device  10  and fix the electronic device  10  therein to thereby stably protect the electronic device  10  from external impacts. 
         [0068]    The present embodiment illustrates a case in which the base substrate  60  is attached to an exterior of the molding part  70 . In this case, five surfaces of the base substrate  60  is exposed to the outside, thereby allowing for an increase in a heat dissipation effect. 
         [0069]    However, the present invention is not limited thereto. For example, a part of the base substrate  60  may be covered by the molding part  70 . In this case, at least one surface of each of the base substrates  60  maybe exposed out of the molding part  70 . 
         [0070]    Due to this structure, the semiconductor package  100  according to the present embodiment is formed to have a substantially rectangular parallelepiped shape by the base substrate  60  and the molding part  70 , and the substrates  80  for dissipating heat may be disposed on at least two surfaces of the semiconductor package  100  having a rectangular parallelepiped shape and exposed to the outside. 
         [0071]    The molding part  70  may be formed of an insulating material. In particular, the molding part  70  may be formed of a material having high thermal conductivity, such as silicone gel, thermally-conductive epoxy, ployimide, or the like. 
         [0072]    Referring back to  FIG. 1 , the heat dissipation member  90  according to the present embodiment may contact an outer surface of the semiconductor package  100 , absorb heat generated from the semiconductor package  100 , and then, dissipate the heat to the outside. 
         [0073]      FIG. 5  is a cross-sectional view of the semiconductor package module taken along line A-B of  FIG. 1 .  FIG. 6  is a cross-sectional view of the semiconductor package module taken along line C-D of  FIG. 1 , in which the bus bar  30  and the substrate  80  are not shown. In addition,  FIG. 7  is an exploded perspective view of the semiconductor package module  1  of  FIG. 1 . 
         [0074]    Referring to  FIGS. 5 through 7 , the heat dissipation member  90  according to the present embodiment may include a pipe shaped housing forming an external wall, at least one through hole  98  formed in the housing, and an inlet  91   a  and an outlet  91   b  through which a refrigerant is introduced and discharged. 
         [0075]    The semiconductor package  100  is inserted into the through hole  98  to be coupled to the heat dissipation member  90 . 
         [0076]    The through hole  98  is formed to completely penetrate the housing of the heat dissipation member  90  and may be a hole having a shape corresponding to the shape of the semiconductor package  100 . According to the present embodiment, the semiconductor package  100  has a rectangular parallelepiped shape overall. Accordingly, the through hole  98  may be a hole having a rectangular cross section. 
         [0077]    In addition, the heat dissipation member  90  may include a support protrusion  94  that is formed at either opening of both ends of the through hole  98 . The support protrusion  94  may be provided to prevent the semiconductor package  100  inserted into the through hole  98  from being escaped from the through hole  98 . 
         [0078]    Thus, the semiconductor package  100  is fixed into the through hole  98  in such a manner that the semiconductor package  100  is inserted through one end of the through hole  98  and does not escaped from the other end of the through hole  98  by the support protrusion  94  formed at the other end of the through hole  98 . 
         [0079]    As described above, the housing of the heat dissipation member  90  may have a pipe shape. Thus, a void is formed in the housing and is used as a flow channel  92  through which a refrigerant flows. 
         [0080]    That is, the heat dissipation member  90  according to the present embodiment may be a heat dissipation device for dissipating heat of the semiconductor package  100  by using the refrigerant. In this case, example of the refrigerant may include liquid such as water, or gas. 
         [0081]    To this end, the heat dissipation member  90  according to the present embodiment may include the inlet  91   a  through which the refrigerant is introduced to the flow channel  92 , and the outlet  91   b  through which the refrigerant has absorb heat while passing through the heat dissipation member  90  is discharged from the heat dissipation member  90 . 
         [0082]    According to the present embodiment, the inlet  91   a  and the outlet  91   b  are disposed at either end of the housing. However, the present invention is not limited thereto. If necessary, the inlet  91   a  and the outlet  91   b  may be disposed at various positions. 
         [0083]    In addition, in the heat dissipation member  90  according to the present embodiment, at least one protrusion  94  may be formed in the flow channel  92  in order to increase a heat dissipation effect. 
         [0084]    As shown in  FIG. 6 , the protrusion  94  protrudes into the flow channel  92  and guides a flow of a refrigerant along the flow channel  92  toward the semiconductor package  100 . 
         [0085]    The protrusion  94  is disposed in a space formed between through holes  98 . A flow direction of the refrigerant in the flow channel  92  is changed by the protrusion  94 . A path may be formed such the refrigerant may contact a side wall of the through hole  98  due to the protrusion  94  for as long period of time as possible. Thus, the refrigerant may absorb as much amount of heat as possible when transferring in the flow channel  92 . 
         [0086]    According to the present embodiment, the semiconductor package module  1  having the above-described embodiment may normally operate when the anode electrode  14   b  of the diode device  14  is electrically connected to the emitter electrode  12   b  of the power semiconductor device  12 . 
         [0087]    To this end, a structure for electrically connecting the anode electrode  14   b  and the emitter electrode  12   b  to each other is further included in the semiconductor package  100  according to the related art. 
         [0088]    However, in the semiconductor package  100  according to the present embodiment, the anode electrode  14   b  and the emitter electrode  12   b  are not connected to each other in the package  100 , while the anode electrode  14   b  and the emitter electrode  12   b  are connected to each other on the substrate  80  on which the semiconductor package  100  is mounted. 
         [0089]    As shown in  FIG. 7 , the substrate  80  having the semiconductor package  100  mounted thereon maybe provided with a plurality of electrode pads  81  to which respective external connection terminals  20  are bonded. In detail, the electrode pads  81  may include first, second, and third electrode pads  82 ,  84 , and  86 , and a connection pattern  89 . 
         [0090]    According to the present embodiment, the first electrode pad  82  may be a gate electrode pad to which a gate connection terminal  22  that is the first connection terminal  22  is bonded, the second electrode pad  84  may be an emitter electrode pad to which an emitter connection terminal that is the second connection terminal  24  is bonded, and the third electrode pattern  86  may be an anode electrode pad to which an anode connection terminal that is the third connection terminal  26  is bonded. 
         [0091]    In addition, according to the present embodiment, the electrode pads  81  may include the connection pattern  89  for electrically connecting the second electrode pad  84  and the third electrode pattern  86 , that is, the emitter electrode pad and the anode electrode pad, to each other. 
         [0092]    Thus, when the semiconductor package  100  is mounted on the substrate  80 , the second connection terminal  24 , that is, the emitter connection terminal and the third connection terminal  26 , that is, the anode connection terminal, of the semiconductor package  100  are electrically connected to each other by the connection pattern  89  of the substrate  80 , thereby completely forming an overall circuit of the semiconductor package  100 . 
         [0093]    Thus, the semiconductor package  100  according to the present embodiment is mounted on the substrate  80  to be normally operated. 
         [0094]    According to the present embodiment, the connection pattern  89  is formed on one surface of the substrate  80 . However, the present invention is not limited thereto. That is, various applications maybe used in the present invention. For example, a connection pattern may be formed through wiring patterns formed in multilayered substrates or maybe formed on the other surface of the substrate  80 . 
         [0095]    The present embodiment illustrates a case in which respective external connection terminals  20  are bonded to the electrode pads  81  of the substrate  80 , and the semiconductor package  100  is mounted on the substrate  80 . In this case, the external connection terminals  20  maybe bonded to the electrode pads  81  via a solder or the like. 
         [0096]    The present invention is not limited to the above-described structure and various applications maybe used therein. 
         [0097]    For example, the connection pattern  89  of the substrate  80  may be omitted, and the emitter connection terminal as the second connection terminal  24  and the anode connection terminal as the third connection terminal  26  may be electrically connected to each other by using a separate connecting member (e.g., a conductive wire, a clamp, or the like). 
         [0098]    A plurality of coupling holes  88  for coupling an external wire (not shown) thereto may be formed in an edge surface of the substrate  80 . 
         [0099]    Thus, the coupling holes  88  may be electrically connected to the electrode pads  81  via wirings pattern of the substrate  80 . The semiconductor package  100  may be provided in plural and respective packages  100  may be electrically connected to an external device (e.g., an inverter system) via an external wire coupled to the coupling holes  88 . 
         [0100]    If necessary, the coupling holes  88  may be formed in various positions and may be formed in various amounts. 
         [0101]    A bus bar  30  is electrically connected to the common connection terminal  28  of the semiconductor package  100 . In the semiconductor package  100  according to the present embodiment, the common connection terminal  28  protrudes in a direction opposing to a direction in which the remaining external connection terminals  20 , that is, the first, second, and third connection terminals  22 ,  24 , and  26  protrude, such that the bus bar  30  is also disposed at an opposite side of the substrate  80 . 
         [0102]    The bus bar  30  may have a flat bar shape formed of a metal material. At least one coupling hole  32  for coupling an external device (e.g., a housing of an inverter system) thereto or connecting an external wire therewith may be formed in one end of the bus bar  30 . When the bus bar  30  is coupled to an external device, the bus bar  30  may be electrically connected to an external device (e.g., an inverter system). 
         [0103]    In the semiconductor package  100  having the above-described structure according to the present embodiment, the external connection terminal  20  having a plate shape may surface-contact an electrode of the electronic device  10  to be bonded thereto without a bonding wire. Thus, as compared with a semiconductor package according to the related art, bonding reliability may be ensured and a bonding wire may barely be deformed during the formation of the molding part  70 , thereby significantly reducing defects occurring in a manufacturing process in the semiconductor package  100  according to the embodiment of the present invention. 
         [0104]    In addition, unlike a semiconductor package according to the related art, the semiconductor package  100  according to the present embodiment may not include a separate component for electrically connecting the emitter connection terminal as the second connection terminal  24  and the anode connection terminal as the third connection terminal  26  and may be manufactured by repeatedly stacking the first and second devices included in the electronic device  10  and the external connection terminals  20 . Thus, as compared with a semiconductor package according to the related art, the semiconductor package  100  according to the present embodiment may be easily manufactured and the manufacturing time and costs required for the semiconductor package  100  may be minimized. 
         [0105]    In addition, a two-surface heat dissipation structure in which the base substrates  60  are disposed on two surfaces of the electronic device  10  including the first and second devices stacked on each other are applied to the semiconductor package  100  according to the present embodiment. In addition, a heat transfer path formed of a material having high thermal conductivity may be provided between the electronic device  10  and the base substrates  60  and the base substrates  60  may be disposed directly on the external connection terminals  20 , such that a distance between the electronic device  10  and the base substrates  60  may be significantly reduced. 
         [0106]    Thus, significantly improved heat dissipation properties may be obtained as compared with a semiconductor package according to the related art, thereby ensuring a long-term reliability of the semiconductor package  100 . 
         [0107]    The semiconductor package  100  according to the present embodiment is configured in such a manner that the power semiconductor device  12  and the diode device  14  of the electronic device  10  are sequentially stacked rather being disposed on the same plane. Unlike a semiconductor package according to the related art, bonding wires and the like, for electrically connecting the electronic device  10  and the external connection terminals  20  to each other are not used in the semiconductor package  100  according to the present embodiment, and thus, the size of the semiconductor package  100  may be reduced. 
         [0108]    Accordingly, an area for mounting devices may be minimized, and thus, the semiconductor package  100  may be used in various electronic devices that require miniaturization/high integration. 
         [0109]    Furthermore, the semiconductor package module  1  according to the present embodiment may effectively dissipate heat generated from the semiconductor package  100  by using the heat dissipation member  90 . Thus, semiconductor packages  100  that generate an excessive amount of heat may be modularized. 
         [0110]    In addition, the semiconductor package module  1  according to the present embodiment may be configured in such a manner that each of the semiconductor packages  100  may be easily separated from the heat dissipation member  90 . Thus, even if errors arise in a predetermined semiconductor package  100 , only the predetermined semiconductor package  100  may be replaced with a new semiconductor package  100  without replacing the overall semiconductor package module  1  itself. 
         [0111]    Thus, maintenance may be easily performed on the semiconductor package module  1  and costs against errors that arise in the semiconductor package module  1  may be minimized. 
         [0112]    In the semiconductor package module  1  according to the present embodiment, as the semiconductor package  100  is inserted into the through hole  98  of the heat dissipation member  90  and is coupled to the heat dissipation member  90 , four surfaces of the semiconductor package  100  may surface-contact the heat dissipation member  90 . 
         [0113]    That is, the semiconductor package  100  is formed such that the molding part  70 , on which the base substrate  60  is not disposed, as well as the base substrate  60 , may surface-contact the heat dissipation member  90 . 
         [0114]    Thus, both heat transferred from the electronic device  10  to the base substrate  60  and heat transferred through the molding part  70  may be transferred to the heat dissipation member  90  and may be dissipated outwardly, thereby significantly increasing a heat dissipation effect. 
         [0115]    The heat dissipation member  90  according to the present embodiment is not limited to the above-described structure and various applications thereof may be used. 
         [0116]      FIG. 8  is a schematic cross-sectional view of a semiconductor package module according to another embodiment of the present invention and corresponds to the semiconductor package module  1  taken along line C-D of  FIG. 1 . 
         [0117]    The semiconductor package module according to the present embodiment has a similar structure to the above-described embodiment, except for through hole and flow channel structures. Thus, a repeated explanation regarding components the same as those of the above-described embodiment will not be given and the through hole and flow channel structures will be described in greater detail. 
         [0118]    Referring to  FIG. 8 , in the heat dissipation member  90  of a semiconductor package module  2  according to the present embodiment, the through holes  98  are formed to have a diamond shapes. That is, two adjacent through holes  98  are disposed such that two corners of the two adjacent through holes  98  are most adjacent to each other. Likewise, the inlet  91   a  and the outlet  91   b  are respectively disposed adjacent to corners of the through hole  98 . 
         [0119]    Thus, the semiconductor packages  100  disposed within the through holes  98  may be arranged to have diamond shapes in which corners thereof are adjacent to each other. 
         [0120]    As shown in  FIG. 8 , in the heat dissipation member  90  according to the present embodiment, an entire path of the flow channel  92  has a diamond pattern shape. 
         [0121]    Accordingly, the refrigerant introduced into the flow channel  92  through the inlet  91   a  may be divided along the flow channel  92  having a diamond pattern shape, sequentially contact the overall side wall of the through hole  98 , and move toward the outlet  91   b.    
         [0122]    The heat dissipation member  90  according to the present embodiment may allow the refrigerant to contact a maximum area of the side wall of the through hole  98  without any separate protrusion formed in the flow channel  92 , unlike in the above-described embodiment of the present invention. 
         [0123]    When the flow channel  92  has a diamond pattern shape, a heat dissipation effect may be further increased as compared with the above-described embodiment of the present invention. 
         [0124]      FIG. 9  is a graph illustrating a relationship between a pressure reduction in a flow channel of the semiconductor package module according to the embodiment of the present invention and heat dissipation efficiency. With regard to the heat dissipation member  90  shown in  FIGS. 6 and 8 , when pressure in divided flow channels P 1  and P 1 ′ is 1,a flow channel cross-sectional area at intersections P 2  and P 2 ′ at which the divided flow channels P 1  and P 1 ′ are combined is increased, pressure in the intersections P 2  and P 2 ′ is reduced. 
         [0125]    Through a simulation, in the case of the heat dissipation member  90  shown in  FIG. 6 , it was measured that pressure in the intersection P 2  at which the divided flow channels P 1  are combined is remarkably reduced, and accordingly, dissipation efficiency is lowered by about 35%. 
         [0126]    However, in the case of the heat dissipation member  90  shown in  FIG. 8 , it was measured that pressure in the intersection P 2 ′ at which the divided flow channels P 1 ′ are combined is barely reduced, and thus, dissipation efficiency is maintained to about 90%. 
         [0127]    Accordingly, it is confirmed that, when the heat dissipation member  90  according to the embodiments of the present invention is configured in such a manner that the flow channel  92  has a diamond pattern shape, a heat dissipation effect maybe further increased. However, the preset invention is not limited thereto. That is, the flow channel  92  may be formed in various forms as long as the flow channel  92  may significantly increase a heat dissipation effect. 
         [0128]    The semiconductor package is not limited to the above-described embodiments of the present invention and various applications thereof may be used. For example, according to the embodiments of the present invention, the semiconductor package has a rectangular parallelepiped shape overall, but the present invention is not limited thereto. That is, the semiconductor package may have a cylindrical shape, a polyprism shape, or the like, as needed. 
         [0129]    In addition, to the embodiments of the present invention exemplifies a power semiconductor package. However, the present invention is not limited thereto and an electronic component in which at least one electronic device is packaged may be applied to the present invention. 
         [0130]    As set forth above, according to the embodiments of the present invention, the semiconductor package module may effectively dissipate heat generated from a semiconductor package by using a heat dissipation member. Thus, power semiconductor packages that generate an excessive amount of heat may be modularized. 
         [0131]    Furthermore, the semiconductor packages may be easily separated from the heat dissipation member. That is, even if errors arise in a predetermined semiconductor package, only the predetermined semiconductor package may be replaced with a new semiconductor package without replacing the overall semiconductor package module itself. Thus, maintenance of the semiconductor package module maybe easily performed and costs against errors that arise in the semiconductor package module may be minimized. 
         [0132]    In the semiconductor package module according to the above-described embodiments of the present embodiment, the semiconductor package is inserted into a through hole of the heat dissipation member and is coupled to the heat dissipation member, such that four surfaces of the semiconductor package may surface-contact the heat dissipation member. That is, the semiconductor package is formed such that a molding part, on which a base substrate is not disposed, as well as the base substrate may surface-contact the heat dissipation member. 
         [0133]    Thus, both heat transferred from an electronic device to the base substrate and heat transferred through the molding part may be transferred to the heat dissipation member and may be dissipated outwardly, thereby significantly increasing a heat dissipation effect. 
         [0134]    While the present invention has been shown and described in connection with the embodiments, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims.
