封裝結構 Package structure

本發明提供一種封裝結構,尤指一種具有散熱功能及圍繞電子元件之周圍金屬邊緣部的封裝結構。 The present invention provides a package structure, and more particularly to a package structure having a heat dissipation function and surrounding a metal edge portion of the electronic component.

習知用於板材(Substrate Panel)結構或晶圓形式之排列結構的半導體封裝件切單技術是使用刀切方式,但是其最大可切單版面尺寸僅止於12吋,約300毫米見方大小,而若使用雷射切單技術,則最大可切單版面尺寸可以達到500毫米見方。 It is conventional to use a knife-cutting method for a semiconductor package singulation technique for a Substrate Panel structure or a wafer-type arrangement structure, but the maximum singable stencil size is only about 12 吋, about 300 mm square. With the laser singulation technology, the maximum singable stencil size can reach 500 mm square.

請參照第1及1’圖,其分別係例如為由習知之扇出(fan out)結構的半導體封裝件所組成之整版面之封裝結構的剖視圖及俯視圖,但為了方便說明,第1圖僅顯示第1’圖之一部分。整版面之封裝結構1’係由陣列排列之複數封裝結構1所組成,封裝結構1係包括晶片11、封裝膠體10、導電開口131、介電層132及線路層133。 Please refer to FIG. 1 and FIG. 1 respectively, which are respectively a cross-sectional view and a plan view of a package structure of a full-face surface composed of a conventional semiconductor package having a fan out structure, but for convenience of description, FIG. 1 only shows Show a part of the 1' diagram. The package structure 1' of the entire layout is composed of a plurality of package structures 1 arranged in an array. The package structure 1 includes a wafer 11, an encapsulant 10, a conductive opening 131, a dielectric layer 132, and a wiring layer 133.

如上所述之封裝膠體10具有相對之第一表面10a及第二表面10b,複數晶片11係嵌埋於封裝膠體10中,並外露出第一表面10a,而晶片11具有相對之非作用面11b及作用面11a,而作用面11a具有電極墊111且作用面11a 外露出第一表面10a。 The encapsulant 10 as described above has a first surface 10a and a second surface 10b opposite thereto, the plurality of wafers 11 are embedded in the encapsulant 10, and the first surface 10a is exposed, and the wafer 11 has a non-active surface 11b. And the action surface 11a, and the active surface 11a has the electrode pad 111 and the active surface 11a The first surface 10a is exposed.

如上所述之介電層132形成在封裝膠體10之第一表面10a及作用面11a上,導電開口131形成在介電層132中且電性連接電極墊111,線路層133形成在介電層132上並電性連接導電開口131,並且線路層133上可形成有銲球15,而導電開口131、介電層132及線路層133係構成一重佈線層(Re-distribution layer,RDL)13。相鄰封裝結構1之間具有一間距P1,以做為後續雷射切單所需空間。而在以雷射(未圖示)切單習知之整版面之封裝結構1’時,由於封裝膠體10及各相鄰重佈線層13係彼此相連,且封裝膠體10之封裝膠體材料及各相鄰重佈線層13中的介電層132之介電材料係為導熱甚差、熔點較低或二者之膨脹係數差異較大的材料,因此,高熱之雷射往往造成介電層與線路層剝離、線路層損傷或封裝結構外觀燒蝕等等的熱損傷問題,從而在應用雷射切單整版面之封裝結構時大大地降低了封裝結構的生產良率及封裝結構的可靠性,並且由於上述生產良率及可靠性問題,仍無法導入用於12吋以上之整版面之封裝結構的雷射切單製程。 The dielectric layer 132 is formed on the first surface 10a and the active surface 11a of the encapsulant 10. The conductive opening 131 is formed in the dielectric layer 132 and electrically connected to the electrode pad 111. The circuit layer 133 is formed on the dielectric layer. The conductive opening 131 is electrically connected to the 132, and the solder ball 15 is formed on the circuit layer 133, and the conductive opening 131, the dielectric layer 132 and the wiring layer 133 form a redistribution layer (RDL) 13. 1 between adjacent package structure having a pitch P 1, as the space required subsequent to laser singulation. When the package structure 1' of the entire layout is cut by a laser (not shown), since the encapsulant 10 and the adjacent redistribution layers 13 are connected to each other, and the encapsulant colloid material and the phases of the encapsulant 10 are assembled. The dielectric material of the dielectric layer 132 in the adjacent heavy wiring layer 13 is a material having poor thermal conductivity, a low melting point, or a large difference in expansion coefficients between the two. Therefore, a high heat laser often causes a dielectric layer and a circuit layer. Thermal damage problems such as peeling, damage to the wiring layer or ablation of the package structure, etc., thereby greatly reducing the production yield of the package structure and the reliability of the package structure when applying the laser-cut single-package package structure, and The above-mentioned production yield and reliability problems still cannot be imported into a laser singulation process for a package structure of a full-face surface of 12 吋 or more.

然而值得注意的是,各金屬邊緣部29之平面投影形狀 可為具有封閉路徑的形狀,或者金屬邊緣部29之平面投影形狀可具有如第2B’或5B’圖中的缺口291。另外,金屬邊緣部29可如第2B’或5B’圖所示地具有往電子元件21之平面投影方向延伸的延伸部292。 However, it is worth noting that the planar projection shape of each metal edge portion 29 The shape may have a closed path, or the planar projection shape of the metal edge portion 29 may have a notch 291 as in the 2B' or 5B' diagram. Further, the metal edge portion 29 may have an extending portion 292 extending toward the plane projection direction of the electronic component 21 as shown in the second B' or 5B'.

另外,金屬邊緣部29之厚度D1與封裝結構2之厚度D2的比例、金屬邊緣部29之材料及各金屬邊緣部29之間的間距P2等特性已於上述各態樣中詳述,在此不再贅述。 Further, the thickness ratio of the metal edge portions 29 of the D 1 and D 2 of the thickness of the package 2, the spacing 29 between the edge portion 29 of the metal material and each metal edge portion P 2 has characteristics such as detailed in the above aspects , will not repeat them here.

最後,如第7B圖所示,以雷射3沿任二相鄰之金屬邊緣部29間的路徑燒灼,以對整版面之封裝結構2’進行切單而構成如第7B圖所示的複數封裝結構2,而以雷射3對整版面之封裝結構2’進行切單之詳細內容已在上文說明,故不再贅述。 Finally, as shown in FIG. 7B, the laser 3 is cauterized along a path between any two adjacent metal edge portions 29 to singulate the package structure 2' of the entire layout to form a complex number as shown in FIG. 7B. The details of the package structure 2 and the singulation of the package structure 2' of the full-face by the laser 3 have been described above, and therefore will not be described again.

綜上所述,相較於先前技術,由於本發明係藉由圍繞電子元件之各周圍金屬邊緣部而避免習知技術之在雷射燒灼相鄰各周圍金屬邊緣部之間的介電材料、封裝膠體或其二者時所造成的介電層與線路層剝離、線路層損傷或封裝結構外觀燒蝕等等的諸多熱損傷問題,從而在應用雷射切單整版面之封裝結構時,大為提高封裝結構的生產良率及提升封裝結構的可靠性,並因此可在12吋以上之整版面之封裝結構使用雷射切單製程。 In summary, compared to the prior art, the present invention avoids the dielectric material between the adjacent peripheral metal edge portions of the laser to be ablated by the prior art by surrounding the peripheral metal edge portions of the electronic component. Many thermal damage problems caused by dielectric layer and circuit layer peeling, circuit layer damage or package structure ablation caused by encapsulation of the colloid or both, so that when applying a laser-cut single-panel package structure, In order to improve the production yield of the package structure and improve the reliability of the package structure, it is possible to use a laser singulation process in a package structure of more than 12 整.
