Abstract
The invention discloses a pin-type heat-radiating semiconductor packaging structure. The pin-type heat-radiating semiconductor packaging structure comprises a semiconductor chip, a packaging layer, a curved heat-radiating pin and a copper wire net. The copper wire net is laid on the upper surface of the semiconductor chip. The curved heat-radiating pin comprises a heat-conducting portion and a heat-radiating portion connected with the heat-conducting portion. The heat-conducting portion is laid on the surface of the copper wire net. The packaging layer wraps and covers the semiconductor chip, the copper wire net and the heat-conducting portion. The heat-radiating portion is exposed outside the packaging layer. The surface of the heat-radiating portion is coated with insulated heat-conducting glue.

Description
Technical field
The present invention relates to a kind of semiconductor package, particularly relate to a kind of semiconductor package with heat sinking function.
Technical background
At present, for semiconductor packaging industry, the heating of powerful chip causes chip temperature to raise, and then cause the reduction in chip life-span, in order to reduce the temperature of chip, people are generally dispelled the heat at wafer surface attachment fin, and fin is all adopt the mode increasing height to realize usually, be difficult to the occasion being applied to ultra-thin installing space, and the installation of fin easily causes the circuit in installing space to occur short-circuit fault, and due in the long-term exposed air of fin, fin surface easily piles up increasing dust, the radiating efficiency of fin is caused to reduce, therefore, a kind of new solution is needed to solve the problem better.
Summary of the invention
Instant invention overcomes deficiency of the prior art, provide the semiconductor package of a kind of pin type heat radiation.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of semiconductor package of pin type heat radiation, comprise semiconductor chip, encapsulated layer, heat radiation looper and copper mesh, described copper mesh tiling is arranged on semiconductor chip upper surface, described heat radiation looper comprises heat-conducting part and radiating part, described heat-conducting part is connected with radiating part, described heat-conducting part tiling is arranged on the surface of copper mesh, described encapsulated layer parcel covers semiconductor chip, copper mesh and heat-conducting part, the exposed outside at encapsulated layer of described radiating part, described radiating part surface scribbles thermal plastic insulation.
As preferably, the cross section of described heat radiation looper is circular, and diameter is 0.2 ~ 1mm.
As preferably, described radiating part comprises the first radiating part, the second radiating part and the 3rd radiating part, described first radiating part is connected with heat-conducting part, described first radiating part to be contacted mutually with the 3rd radiating part by the second radiating part and is connect, described first radiating part, the second radiating part and the 3rd radiating part are in same plane, described second radiating part perpendicular to the upper surface of semiconductor chip to downward-extension, described second radiating part length is no more than the bottom surface of encapsulated layer, and described 3rd radiating part is arranged between the second radiating part and encapsulated layer.
As preferably, described 3rd radiating part is L shape, and one end is connected with the second radiating part, and the other end is upwards arranged perpendicular to the upper surface of semiconductor chip.
Compared with prior art, advantage of the present invention is: the assistance heat conduction of copper mesh significantly can reduce the temperature rise of semiconductor chip central part; The heat radiation looper of minor diameter can increase overall area of dissipation, also can allow the more difficult adhesion of dust simultaneously, improving heat radiation efficiency; 3rd radiating part of heat radiation looper is hidden in the first radiating part, avoids between the second radiating part and encapsulated layer directly accumulating dust, effectively ensures radiating efficiency; The surrounding being distributed in encapsulated layer due to heat radiation looper is close to encapsulated layer, makes overall package structure not increase height, does not also significantly increase simultaneously on width; Due to heat radiation looper scribbling thermal plastic insulation, the probability of extra short-circuit fault can be there is by the circuit effectively reduced in installing space.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
As shown in Figure 1, a kind of semiconductor package of pin type heat radiation, comprise semiconductor chip 1, encapsulated layer 2, heat radiation looper 3 and copper mesh 4, described copper mesh 4 tiling is arranged on semiconductor chip 1 upper surface, described heat radiation looper 3 comprises heat-conducting part 34 and radiating part, described heat-conducting part 34 is connected with radiating part, described heat-conducting part 34 tiling is arranged on the surface of copper mesh 4, described encapsulated layer 2 wraps up and covers semiconductor chip 1, copper mesh 4 and heat-conducting part 34, the exposed outside at encapsulated layer 2 of described radiating part, described radiating part surface scribbles thermal plastic insulation, the cross section of described heat radiation looper 3 is circular, diameter is 0.5mm, described radiating part comprises the first radiating part 31, second radiating part 32 and the 3rd radiating part 33, described first radiating part 31 is connected with heat-conducting part 34, described first radiating part 31 to be contacted mutually with the 3rd radiating part 33 by the second radiating part 32 and is connect, described first radiating part 31, second radiating part 32 and the 3rd radiating part 33 are in same plane, described second radiating part 32 perpendicular to the upper surface of semiconductor chip 1 to downward-extension, described second radiating part 32 length is no more than the bottom surface of encapsulated layer 2, described 3rd radiating part 33 is arranged between the second radiating part and encapsulated layer, described 3rd radiating part 33 is L shape, one end is connected with the second radiating part 32, the other end is upwards arranged perpendicular to the upper surface of semiconductor chip 1.
When the present invention works, the heat that semiconductor chip 1 produces rises to copper mesh 4, and copper mesh 4 conducts heat on heat radiation looper 3 and externally dispels the heat, and can effectively avoid the central part of semiconductor chip 1 to produce high temperature rise; The heat radiation looper of 0.5mm diameter can increase overall area of dissipation more, also can allow the more difficult adhesion of dust simultaneously, improving heat radiation efficiency; 3rd radiating part 33 of heat radiation looper is hidden between the first radiating part 31, second radiating part 32 and encapsulated layer 2 to be avoided directly accumulating dust, effectively ensures radiating efficiency; The surrounding being distributed in encapsulated layer due to heat radiation looper 3 is close to encapsulated layer, makes overall package structure not increase height, does not also significantly increase simultaneously on width; Due to heat radiation looper 3 scribbling thermal plastic insulation, the probability of extra short-circuit fault can be there is by the circuit effectively reduced in installing space.
