Definitions
- the invention relates to a chip package structure and a manufacturing method thereof. More particularly, the invention relates to a package carrier and a manufacturing method thereof.
- a leadframe serving as a carrier of a chip is frequently employed in a conventional wire bonding technique. As contact density on a chip gradually increases, the leadframe which is unable to satisfy current demands on the high contact density is replaced by a package substrate which can achieve favorable contact density. Besides, the chip is packaged onto the package substrate by conductive media, such as metal wires or bumps.
- LED chip is packaged before use.
- the LED chip emits light and generates a large amount of thermal energy simultaneously. If the thermal energy generated by the LED chip is unable to quickly dissipate and amasses within the LED package structure, the temperature of the LED package structure will be raised continuously. Therefore, the LED chip may have decayed illumination and a shorter lifetime, and if serious, may even have permanent damage due to overheating.
- the current package technology focuses on decreasing the thermal stress of the package structure to increase the lifetime and the reliability.
- the invention is directed to a package carrier, suitable for carrying a heat generating component.
- the invention is directed to a manufacturing method used to manufacture the package carrier.
- the invention provides a method of fabricating a package carrier.
- the method includes the following steps.
- a substrate is provided.
- the substrate has a top surface and a bottom surface opposite to the top surface.
- a first opening communicating the upper surface and the lower surface of the substrate is formed.
- a heat conducting element inside the first opening of the substrate is formed, wherein the heat conducting element is fixed in the first opening of the substrate via an insulating material.
- At least a through hole passing through the substrate is formed.
- a metal layer is formed on the upper surface and the lower surface of the substrate and inside the through hole, wherein the metal layer covers the upper surface, the lower surface, the heat conducting element, and the insulating material of the substrate.
- a portion of the metal layer is removed.
- a solder mask is formed on a metal layer.
- a surface passivation layer is formed and covers a portion of the metal layer exposed by the solder mask and a portion of the metal layer located inside the through hole.
- the invention further provides a package carrier, suitable for packaging a heat generating component.
- the package carrier includes a substrate, a heat conducting element, an insulating material, a metal layer, a solder mask, and a surface passivation layer.
- the substrate has an upper surface, a lower surface opposite to the upper surface, a first opening communicating the upper surface and the lower surface and at least a through hole.
- the heat conducting element is disposed in the first opening of the substrate.
- the insulating material is filled in the first opening of the substrate to fix the heat conducting element within the first opening of the substrate.
- the metal layer is disposed on the upper surface, the lower surface, and the through hole of the substrate, wherein the metal layer exposes a portion of the substrate.
- the solder mask is disposed on the metal layer.
- the surface passivation layer covers a portion of the metal layer exposed by the solder mask and a portion of the metal layer located inside the through hole, and the heat conducting element is disposed on a portion of the surface passivation
- the package carrier of the invention has a heat conducting element, and the heat conducting element is embedded in the substrate. Therefore, when a heat generating component mounted on the package carrier generates heat, the heat conducting element and the metal layer of the substrate can quickly transmit the heat to the outside. Therefore, the package carrier of the invention can effectively dissipate the heat generated by the heat generating component, and thus improves the effectiveness and longevity of the heat generating component.

Description
- This application is a Divisional of and claims the priority benefit of U.S. patent application Ser. No. 13/090,285, filed on Apr. 20, 2011, now pending, which claims the priority benefits of Taiwan application Serial No. 100101972, filed on Jan. 19, 2011. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of specification.
- 1. Field of the Invention
- The invention relates to a chip package structure and a manufacturing method thereof. More particularly, the invention relates to a package carrier and a manufacturing method thereof.
- 2. Description of Related Art
- The purpose of a chip package is to protect a bare chip, lower the chip contact density, and provide the chip with good heat dissipation. A leadframe serving as a carrier of a chip is frequently employed in a conventional wire bonding technique. As contact density on a chip gradually increases, the leadframe which is unable to satisfy current demands on the high contact density is replaced by a package substrate which can achieve favorable contact density. Besides, the chip is packaged onto the package substrate by conductive media, such as metal wires or bumps.
- Regarding current and common light emitting diode (LED) package structures, an LED chip is packaged before use. The LED chip emits light and generates a large amount of thermal energy simultaneously. If the thermal energy generated by the LED chip is unable to quickly dissipate and amasses within the LED package structure, the temperature of the LED package structure will be raised continuously. Therefore, the LED chip may have decayed illumination and a shorter lifetime, and if serious, may even have permanent damage due to overheating.
- Since the thermal expansion coefficients of a LED chip and a package carrier are mismatched, the generated thermal stress and warpage are more and more critical so that the reliability of the LED package structure is lowered. Thus, besides enhancing the light extraction efficiency, the current package technology focuses on decreasing the thermal stress of the package structure to increase the lifetime and the reliability.
- The invention is directed to a package carrier, suitable for carrying a heat generating component.
- The invention is directed to a manufacturing method used to manufacture the package carrier.
- The invention provides a method of fabricating a package carrier. The method includes the following steps. A substrate is provided. The substrate has a top surface and a bottom surface opposite to the top surface. A first opening communicating the upper surface and the lower surface of the substrate is formed. A heat conducting element inside the first opening of the substrate is formed, wherein the heat conducting element is fixed in the first opening of the substrate via an insulating material. At least a through hole passing through the substrate is formed. A metal layer is formed on the upper surface and the lower surface of the substrate and inside the through hole, wherein the metal layer covers the upper surface, the lower surface, the heat conducting element, and the insulating material of the substrate. A portion of the metal layer is removed. A solder mask is formed on a metal layer. A surface passivation layer is formed and covers a portion of the metal layer exposed by the solder mask and a portion of the metal layer located inside the through hole.
- The invention further provides a package carrier, suitable for packaging a heat generating component. The package carrier includes a substrate, a heat conducting element, an insulating material, a metal layer, a solder mask, and a surface passivation layer. The substrate has an upper surface, a lower surface opposite to the upper surface, a first opening communicating the upper surface and the lower surface and at least a through hole. The heat conducting element is disposed in the first opening of the substrate. The insulating material is filled in the first opening of the substrate to fix the heat conducting element within the first opening of the substrate. The metal layer is disposed on the upper surface, the lower surface, and the through hole of the substrate, wherein the metal layer exposes a portion of the substrate. The solder mask is disposed on the metal layer. The surface passivation layer covers a portion of the metal layer exposed by the solder mask and a portion of the metal layer located inside the through hole, and the heat conducting element is disposed on a portion of the surface passivation layer over the heat conducting element.
- Based on the above, the package carrier of the invention has a heat conducting element, and the heat conducting element is embedded in the substrate. Therefore, when a heat generating component mounted on the package carrier generates heat, the heat conducting element and the metal layer of the substrate can quickly transmit the heat to the outside. Therefore, the package carrier of the invention can effectively dissipate the heat generated by the heat generating component, and thus improves the effectiveness and longevity of the heat generating component.

hole 117 b and disposing theheat conducting element 120, even though the steps are described as first forming the throughhole 117 b and then disposing theheat conducting element 120 in thefirst opening 115 b. Of course, in another embodiment, theheat conducting element 120 can first be disposed in thefirst opening 115 b, and then the throughhole 117 b is formed. Hence, the sequence of the steps of forming the throughhole 117 b and disposing theheat conducting element 120 is merely exemplary and is not limited thereto. - Next, referring to
FIG. 3D , ametal layer 140 is formed on theupper surface 111 b and thelower surface 113 b of thesubstrate 110 b and inside the throughhole 117 b of thesubstrate 110 b, wherein themetal layer 140 covers theupper surface 111 b and thelower surface 113 b of thesubstrate 110 b, theheat conducting element 120, and the insulatingmaterial 130. In the embodiment, the step of forming theconductive layer 140 is, for example, electroplating. - Next, referring to
FIG. 3E , a portion of themetal layer 140 is removed to expose a portion of each of the insulatingblocks 114 b located in thesecond opening 119 b. Then, asolder mask 150 is formed on themetal layer 140. Finally, asurface passivation layer 160 is formed, wherein thesurface passivation layer 160 covers a portion of themetal layer 140 exposed by thesolder mask 150 and a portion of themetal layer 140 located inside the throughhole 117 b, and further covers a portion of themetal layer 140 exposed by the insulatingblock 114 b. In the embodiment, a material of thesurface passivation layer 160 includes, for example, Ni and Au. As such, apackage carrier 100 b is completely formed. - Structurally, the
package carrier 100 b of the embodiment includes thesubstrate 110 b, theheat conducting element 120, the insulatingmaterial 130, themetal layer 140, thesolder mask 150, and thesurface passivation layer 160. Thesubstrate 110 b is constructed of themetal plate 112 b and the insulatingblocks 114 b. Thesubstrate 110 b has theupper surface 111 b and thelower surface 113 b opposite to theupper surface 111 b. Themetal plate 112 b has thefirst opening 115 b and thesecond opening 119 b, and the insulatingblocks 114 b have the throughholes 117 b. Theheat conducting element 120 is disposed in thefirst opening 115 b of themetal plate 112 b. The insulatingmaterial 130 is filled in thefirst opening 115 b to fix theheat conducting element 120 within thefirst opening 115 b. Themetal layer 140 is disposed on theupper surface 111 b and thelower surface 113 b of thesubstrate 110 b and inside the throughhole 117 b, and exposes a portion of each of the insulatingblock 114 b located on the correspondingsecond opening 119 b. Thesolder mask 150 is disposed on themetal layer 140. Thesurface passivation layer 160 covers a portion of themetal layer 140 exposed by thesolder mask 150 and a portion of themetal layer 140 located inside the throughhole 117 b, and further covers a portion of themetal layer 140 exposed by the insulatingblock 114 b. -
FIG. 4 is a cross-sectional view illustrating the package carrier ofFIG. 3E carrying a heat generating component. Referring toFIG. 4 , in the embodiment, thepackage carrier 100 b is suitable to carry aheat generating component 200, wherein theheat generating component 200 is disposed on a portion of thesurface passivation layer 160 over the correspondingheat conducting element 120, and theheat generating component 200 is, for example, an electronic chip or an optoelectronic component, but the invention is not limited thereto. For example, the electronic chip can be an integrated circuit chip such as a graphic chip or a memory chip, and can be a single chip or a chip module. The optoelectronic component is, for example, an LED, a laser diode, or a high intensity discharge lamp. Theheat generating component 200 is described as an LED. - In detail, the heat generating component 200 (e.g. a semiconductor chip) can be electrically connected to the
surface passivation layer 160 through wire bonding with a plurality ofconductive wires 220. Anencapsulant 210 can also be used to cover theheat generating component 200, theconductive wires 220 and a portion of thepackage carrier 100 b so as to protect the electrical connection between theheat generating component 200, and theconductive wires 220 and thepackage carrier 100 b. Since the thermal expansion coefficient of theheat conducting element 120 of the embodiment is less than the thermal expansion coefficient of thesubstrate 110 b, the difference between the thermal expansion coefficients of theheat generating component 200, theheat conducting element 120 and thesubstrate 110 b can be gradually decreased. Thus, the increase of stress because of the thermal expansion coefficient difference from being too great between theheat generating component 200, theheat conducting element 120, and thesubstrate 110 b can be avoided. Also, theheat generating component 200 can be prevented from peeling and damage, and thus the reliability of thepackage carrier 100 b is raised. - In addition, since the thermal conductivity coefficient of the
heat conducting element 120 is greater than the thermal conductivity coefficient of thesubstrate 110 b, and theheat conducting element 120 is embedded in thesubstrate 110 b, the heat generated by theheat generating component 200 disposed on thepackage carrier 100 b can be quickly transmitted to the outside through theheat conducting element 120 and themetal layer 140 on thesubstrate 110 b. Therefore, thepackage carrier 100 b of the embodiment can effectively dissipate the heat generated by theheat generating component 200, and thus the effectiveness and longevity of theheat generating component 200 is improved. - It should be noted that even though the embodiment describes the
heat generating component 200 is electrically connected to thepackage carrier 100 b and themetal layer 140 through wiring bonding, the invention does not limit the bonding type between theheat generating component 200 and thepackage carrier 100 b, and the type of theheat generating component 200. In another embodiment, theheat generating component 200 can also be electrically connected and located on themetal layer 140 over theheat conducting element 120 through a plurality of bumps (not shown) by flip chip bonding. In still another embodiment, theheat generating component 200 can be a chip package (not shown) mounted on thepackage carrier 100 b through surface mount technology (SMT). The bonding type betweenheat generating component 200 and thepackage carrier 100 b and the type of theheat generating component 200 are merely exemplary and should not be construed as limitations to the invention. - To sum up, since the package carrier of the invention has a heat conducting element, and the heat conducting element is embedded in the substrate so that the heat generated by the heat generating component disposed on the package carrier can be quickly transmitted to the outside through the heat conducting element and the metal layer on the substrate. Therefore, the package carrier of the invention can effectively dissipate the heat generated by the heat generating component, and thus the effectiveness and longevity of the heat generating component is improved. Since the thermal expansion coefficient of the heat conducting element of the invention is less than the thermal expansion coefficient of the substrate, the difference between the thermal expansion coefficients of the heat generating component, the heat conducting element and the substrate can be gradually decreased. Thus, the increase of stress because of the thermal expansion coefficient difference from being too great between the heat generating component, the heat conducting element, and the substrate can be avoided. Also, the heat generating component can be prevented from peeling and damage, and thus the reliability of the package carrier is raised.
- Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
