Circuits)。但半導體晶片之積體化密度 (Integrated Density)越高,其在運作時所產生之熱量= 越大,若不能有效逸散所產生之熱量,則會對半導體晶月 造成損害。故遂有於半導體封裝件中加設散熱片 Sink或Heat Spreader)之設計發展出,以藉散熱片逸散 出半導體晶片所產生之熱量。 籲 具有散熱片之半導體封裝件已揭露於第 5’883, 430、5, 604’978、6,

發明之可實施範圍於一特定之態樣(Emb〇diment)。 J 一實施例 如第1A圖所示者,為本發明第一實施例之半導體封 裝件之剖視圖。該第一實施例之半導體封裝件丨係由基板 10,黏设於該基板10上之半導體晶片11、黏設於該半導 體BB片11上之散熱結構12、以及形成於該基板上、 以包覆該半導體晶片11與部分之散熱結構12之封裝膠體 111047 10 201019429 13所構成者。 該基板10在本實施例中為習用之覆晶基板,以供該 半導體晶片11以覆晶方式(Flip Chip)藉複數銲錫凸塊 (Solder BumPS)14電性連接至該基板1〇之上表面1〇〇之 預設位置上;同時’相對於該上表面1〇〇之下表面m 上,則植设有複數顆成陣列(Array)方式排列的銲球 (Solder Balls)15,以使該半導體晶片u能藉由該銲球 15而與外界裝置(如印刷電路板)電性連接。由於該基板 ⑩10為習知者,且以覆晶方式將半導體晶片n設於基板⑺ 與知球之植接亦為習用技術,故在此不予贅述。 該散熱結構12係由黏著劑120、結合於該黏著劑12〇 中之第一散熱件121、及黏結於該黏著劑12〇上之第二散 熱件122所構成。該黏著劑12〇得使用如銀膠 Paste)或環氧樹脂黏膠“卯” Resin Adhesive)之習用

相同的高度,使該黏著劑12〇與第一散熱件121結合後, 該黏著劑120之上表面12Qa與第—散熱件121之頂面 121a旎齊平,且該黏著劑12〇之下表面12仳與第一散熱 111047 11 201019429 件12i之底面121b能齊平,以令該第一散熱件ΐ2ι能以 -其頂面121a及底面121b分別抵接至該第二散埶件122 '之底面122b及半導體晶片1卜俾使該半導體晶片U所 產生之熱量能經由該第一散熱件121有效地傳遞至該第 二散熱件122,再由該第二散熱件122將熱量逸散至大氣 中。此外,由於該黏著劑120之上表面12〇a係與第一散 熱件m之頂面121a齊平,而由第一散熱件ΐ2ι之通道 (一網目)121c中外露出’故能有效地以該黏著齊"2〇將第 ©二散熱件122黏結於該散熱結構12中;且,該黏著劑12〇 之下表® 120b係與第一散熱件121之底面mb齊平而

201019429 熱件121形成有多數之通道^(^供黏著劑12〇充填並通 過其中,所以能藉由第一散熱件121之金屬特性降低在後 續之溫度循環中熱應力之產生對黏著劑12〇的影響,而 避免熱應力之影響造成黏著劑120與半導體晶片1J間之 結合介面以及黏著劑120與第二散熱件122間之結合介面 發生脫層現象’遂使脫層之產生所造成之散熱效率變差與 佗賴性問題(ReliabiHty c〇ncern)不致發生。此外,因 有第散熱件121夾置於第二散熱件122與半導體晶片 間,且第一散熱件121係與黏著劑12〇結合,故使第 二散熱件122藉黏著劑120黏結至半導體晶片n上時, 得有第散熱件12丨之支撐不致產生偏斜(Tilt)之現 ^ ’而有效解決習知技術在散熱片與半導體晶片間僅有黏 者層而不易控制散熱片之水平度的問題。 如第2A圖所示者,為本發明第二實施例之半導體封

to a semiconductor package with a heat sink, Yumei is a kind of heat sink to dissipate the semiconductor wafer to generate Semiconductor package. Chaos [Prior Art] As the demand for electronic products in terms of function and processing speed increases, semiconductor wafers, which are the core components of electronic products, must have higher densities: _Electronic Components and Electronic Circuits (Electronic Circuits) ). However, the higher the integrated density of the semiconductor wafer, the greater the amount of heat generated during operation = the greater the heat generated by the semiconductor wafer, and the damage to the semiconductor crystal moon. Therefore, the design of the heat sink Sink or Heat Spreader has been developed in the semiconductor package to dissipate the heat generated by the semiconductor wafer by the heat sink. A semiconductor package having a heat sink has been disclosed in 5'883, 430, 5, 604'978, 6, 008, 536, 6, 376, 907, 6' 403, 882, 6' 472, 762 and 6, US Patent Nos. 504, 723 et al. These U.S. patents disclose the use of different types of heat sinks, but it is preferred to expose the encapsulant on the top surface of the heat sink or directly exposed to the atmosphere to obtain a better heat dissipation effect. However, if the heat sink only exposes the encapsulant on the top surface and does not directly adhere to the semiconductor wafer, and the semiconductor wafer and the heat sink are filled with the encapsulant, the epoxy resin such as the epoxy resin may be formed. Epoxy Res in) Thermal Conduction of Mold Compound 111047 201019429 Very poor 'The heat generated by the semiconductor wafer is still not effectively transmitted to the heat sink and escape to the atmosphere _; therefore, there are also previous techniques to borrow the heat sink The scattered and hot glue is adhered to the semiconductor wafer, so that the heat generated by the semiconductor wafer can be transferred to the heat sink by the heat transfer adhesive with better thermal conductivity to escape to the atmosphere, as shown in FIG. The heat sink (10) of the semiconductor package 8 shown in FIG. 8 is bonded to the semiconductor wafer 82 by the dispersion: the adhesive 81 is an expensive material, which can improve the heat dissipation efficiency, but causes the package cost. The thermal expansion coefficient (Coefficient of Thermal Expansi〇n, (4) is different, so in the temperature cycle of the packaging process, it is often due to thermal expansion. The thermal stress generated by the coefficient difference (CTE Mismatch) causes the interface between the heat sink 8〇 and the heat dissipating gel 81 and/or the interface between the heat dissipating adhesive 81 and the semiconductor wafer 82 to be delaminated. When the layer phenomenon occurs, the semiconductor chip can not effectively dissipate when it generates heat, and it will also be molded and reliable. In addition, when the heat sink 80 is adhered to the wafer 2 by the heat-dissipating glue 81, heat is dissipated. The glue 81 is not cured (Cured), so it is difficult to control the level of the heat sink 80 relative to the semiconductor wafer 82 or the substrate 83 carrying the semiconductor wafer 82, when the heat sink is produced. When tilted, the appearance of the finished product is affected, and the encapsulating compound for forming the encapsulant 66 of the semiconductor wafer 82 is overlaid on the top surface 80a of the heat sink 80, and the heat sink 8 is affected.

The member 121 is effectively transmitted to the second heat sink 122, and then The second heat sink 122 dissipates heat to the atmosphere. In addition, since the upper surface 12〇a of the adhesive 120 is flush with the top surface 121a of the first heat dissipating member m, and is exposed from the first heat dissipating member ΐ2ι (a mesh) 121c, the effective surface can be effectively Adhesively bonding the second heat dissipating member 122 to the heat dissipating structure 12; and, under the adhesive 12, the surface of the surface 120b is flush with the bottom surface mb of the first heat dissipating member 121 by the first heat dissipation The channel 121c of the 21 is exposed to the outside, so that the heat dissipating structure 12 can be effectively adhered to the semiconductor wafer by the adhesive 120.
