Description

本発明は、電子部品実装構造体の製造方法及び該方法により製造された電子部品実装構造体に関する。   The present invention relates to a method for manufacturing an electronic component mounting structure and an electronic component mounting structure manufactured by the method.

従来、プリント配線板等の配線基板上にICチップを直接実装する方法として、バインダー中に導電粒子を分散させた異方性導電フィルムを用いる方法が知られている。
前記異方性導電フィルムを用いた実装方法では、異方性導電フィルムを貼り付けた配線基板上にICチップを搭載した後に、前記ICチップを加圧・加熱して異方性導電フィルムを硬化させて熱圧着実装を行う。
Conventionally, as a method of directly mounting an IC chip on a wiring board such as a printed wiring board, a method using an anisotropic conductive film in which conductive particles are dispersed in a binder is known.
In the mounting method using the anisotropic conductive film, after mounting the IC chip on the wiring substrate on which the anisotropic conductive film is pasted, the IC chip is pressurized and heated to cure the anisotropic conductive film. To perform thermocompression mounting.

ICチップと配線基板との接続にあたっては、両者の位置合わせ(アライメント)を高精度に行う必要がある。即ち、ICチップ上のアライメントマークと、配線基板上のアライメントマークとを認識し、ICチップとそれを貼り付ける配線基板との位置合わせを精密かつ正確に行うことが重要となる。
ここで、アライメントマークの認識の観点から、図1に示すように、異方性導電フィルム10がアライメントマーク20に重ならないように、異方性導電フィルム10を各ICチップ30の大きさに合わせて配線基板に配置するか、または、図2に示すように、異方性導電フィルム10をICチップ30の幅に合わせて帯貼りしていた。そのため、異方性導電フィルムを個々の形状に合わせて貼り付ける必要があり、生産性が低く、また、高精度なフィルム貼付装置を必要としていた。
When connecting the IC chip and the wiring board, it is necessary to align the two with high precision. That is, it is important to recognize the alignment mark on the IC chip and the alignment mark on the wiring board, and to precisely and accurately align the IC chip and the wiring board to which the IC chip is attached.
Here, from the viewpoint of alignment mark recognition, the anisotropic conductive film 10 is adjusted to the size of each IC chip 30 so that the anisotropic conductive film 10 does not overlap the alignment mark 20 as shown in FIG. The anisotropic conductive film 10 is banded according to the width of the IC chip 30 as shown in FIG. Therefore, it is necessary to attach the anisotropic conductive film in conformity with each shape, and the productivity is low, and a highly accurate film sticking apparatus is required.

また、配線基板上にICチップを直接実装するフリップチップ実装において、配線基板のアライメントマークを除いた部分に接着剤層を形成することが行われているが(例えば、特許文献1)、接着剤層を形成する工程が煩雑となり、コスト高となってしまうという問題があった。   In flip chip mounting in which an IC chip is directly mounted on a wiring board, an adhesive layer is formed on a portion of the wiring board excluding the alignment mark (for example, Patent Document 1). There is a problem that the process of forming the layer becomes complicated and the cost becomes high.

<押圧工程>

なお、前記押圧工程では、複数のアライメントマークの直上領域における粒子含有フィルムを、複数の押圧部材を用いて、一括して押圧してもよい。
<Pressing process>
The pressing step is a step of reducing the thickness of the particle-containing film by pressing the particle-containing film in the region immediately above the alignment mark using a pressing member.

<< Pressing >>
There is no restriction | limiting in particular as a pressing force in the said press, Although it can select suitably according to the objective, 1 MPa-100 MPa are preferable, 5 MPa-75 MPa are more preferable, 10 MPa-50 MPa are especially preferable.
If the pressing force is less than 1 MPa, the pressing effect may not be obtained, and if it exceeds 100 MPa, the substrate may be damaged. On the other hand, when the pressing force is within the particularly preferable range, it is advantageous in terms of the balance between the pressure and the readability.
There is no restriction | limiting in particular as a pressing time in the said press, Although it can select suitably according to the objective, 0.01 second-3 second are preferable, 0.05 second-2 second are more preferable, 0.1 second -1 second is particularly preferred.
If the pressing time is less than 0.01 seconds, the pressing effect may not be obtained, and if it exceeds 3 seconds, productivity may be reduced. On the other hand, when the pressing time is within the particularly preferable range, it is advantageous in terms of a balance between productivity and readability.

アライメントマークの直上領域における粒子含有フィルムを押圧すると、該押圧により粒子が押しのけられるため(粒子が押圧方向と同一方向に移動せず、押圧方向と略垂直な方向に移動する)、押圧により薄くなった粒子含有フィルム部分においても、押圧前の粒子含有フィルムにおける粒子密度とほぼ同等な粒子密度で粒子が存在する。よって、粒子含有フィルムが薄くなったことで、アライメントマークの認識がしやすくなり、後述するパターン認識一致度が向上するものと考えられる。   When the particle-containing film in the region immediately above the alignment mark is pressed, the particles are pushed away by the pressing (the particles do not move in the same direction as the pressing direction, but move in a direction substantially perpendicular to the pressing direction), and are thinned by pressing. Also in the particle-containing film portion, particles exist with a particle density substantially equal to the particle density in the particle-containing film before pressing. Accordingly, it is considered that the alignment mark can be easily recognized and the pattern recognition coincidence described later is improved because the particle-containing film is thin.

<<直上領域>>
前記直上領域とは、前記アライメントマークが形成された基材の直交方向から視たときのアライメントマークの頂部の上に位置する領域(図3における領域A)の少なくとも一部を含む領域である限り、特に制限はなく、目的に応じて適宜選択することができるが、前記アライメントマークが形成された基材の直交方向から視たときのアライメントの重心部(中心部)の上に位置する領域を含むことが好ましく、前記アライメントマークが形成された基材の直交方向から視たときのアライメントマークの頂部の上に位置する領域(図3における領域A)を全て含む領域であることがより好ましい。前記アライメントマークが形成された基材の直交方向から視たときのアライメントマークの頂部の上に位置する領域(図3における領域A)を全て含む領域の粒子含有フィルムの厚みを薄くするために、アライメントマークを覆うようにして押圧可能な押圧部材が使用される。
<< directly above area >>
As long as the region directly above is a region including at least a part of a region (region A in FIG. 3) located on the top of the alignment mark when viewed from the orthogonal direction of the base material on which the alignment mark is formed. There is no particular limitation, and it can be appropriately selected according to the purpose, but the region located on the center of gravity (center) of the alignment when viewed from the orthogonal direction of the substrate on which the alignment mark is formed. Preferably, it is a region including all the region (region A in FIG. 3) located on the top of the alignment mark when viewed from the orthogonal direction of the substrate on which the alignment mark is formed. In order to reduce the thickness of the particle-containing film in the region including all the region (region A in FIG. 3) located on the top of the alignment mark when viewed from the orthogonal direction of the substrate on which the alignment mark is formed, A pressing member that can be pressed so as to cover the alignment mark is used.

以下、本発明の実施例について説明するが、本発明は下記実施例に何ら限定されるものではない。   Examples of the present invention will be described below, but the present invention is not limited to the following examples.

(実施例1)
図3及び図4に示すように、TEG基板34(商品名:MCL−E−679F、日立化成工業社製)上に、縦8mm、横8mmのピッチで形成されたアライメントマーク31(コア:銅、Ni/Auメッキ)、断面が直径0.3mmの円形状の円柱形状)上に、異方性導電フィルム32(商品名:FP5530、ソニーケミカル&インフォメーションデバイス株式会社製、厚み:40μm)を貼り付け、円柱形状(底面:直径2mm、高さ:20mm、先端形状が平坦)の金属棒40を用いて、押圧力20MPa、押圧時間1秒間で押圧して凹部(厚みが薄い部分)33を形成し、フリップチップボンダー(商品名:FB30T−M、パナソニック製)を用いて凹部33が直上領域に形成されたアライメントマークの位置に基づいて画定された実装領域にICチップ41を実装して、電子部品実装構造体を作製した。表面粗さ測定機(商品名:SE3500、小坂研究所社製)を用いて、アライメントマーク31上の異方性導電フィルム32の厚みt(μm)(測定位置によって厚さが変化する場合は最小値)を測定し、フリップチップボンダー(商品名:FB30T−M、パナソニック製)を用いてアライメントマーク31のパターン認識一致度数Aを測定し、分光測色計(商品名:CM−3600d、コニカミノルタ製)を用いて光透過率(%)を測定した。
また、図5に示すように、ICチップ41の実装領域内に縦5.5mm、横5.5mmのピッチで形成されたアライメントマーク51(コア:銅、Ni/Auメッキ)、断面が直径0.1 mmの円形状の円柱形状)に対しても、アライメントマーク31の場合と同様に、異方性導電フィルム32を貼り付け、金属棒40を用いて押圧して凹部33を形成して、電子部品実装構造体を作製し、パターン認識一致度数Bを測定した。
なお、前記パターン認識一致度数A及びBは、フリップチップボンダー(商品名:FB30T−M、パナソニック社製)を用いて正規化相関を用いて算出した絶対評価(絶対値である。
また、前記光透過率は、アライメントマーク31、51上の異方性導電フィルム32の厚みの測定結果を用いて、該測定された厚みの異方性導電フィルムの光透過率を算出したものである。よって、異方性導電フィルム32を貼り付ける前の光透過率は、100%となる。
Example 1
As shown in FIGS. 3 and 4, alignment marks 31 (core: copper) formed on a TEG substrate 34 (trade name: MCL-E-679F, manufactured by Hitachi Chemical Co., Ltd.) at a pitch of 8 mm in length and 8 mm in width. Anisotropic conductive film 32 (trade name: FP5530, manufactured by Sony Chemical & Information Device Co., Ltd., thickness: 40 μm) is affixed onto a circular cylinder having a cross section of 0.3 mm in diameter) Using a metal rod 40 having a cylindrical shape (bottom: 2 mm diameter, height: 20 mm, flat tip shape), pressing is performed at a pressure of 20 MPa and a pressing time of 1 second to form a recess (thin portion) 33. In addition, the mounting area is defined based on the position of the alignment mark in which the concave portion 33 is formed in the region immediately above using a flip chip bonder (trade name: FB30T-M, manufactured by Panasonic). An IC chip 41 was mounted on the area to produce an electronic component mounting structure. Using a surface roughness measuring machine (trade name: SE3500, manufactured by Kosaka Laboratory), the thickness t 1 (μm) of the anisotropic conductive film 32 on the alignment mark 31 (when the thickness varies depending on the measurement position) Minimum value) is measured, and the pattern recognition coincidence degree A of the alignment mark 31 is measured using a flip chip bonder (trade name: FB30T-M, manufactured by Panasonic), and a spectrocolorimeter (trade name: CM-3600d, Konica) The light transmittance (%) was measured using Minolta.
Further, as shown in FIG. 5, alignment marks 51 (core: copper, Ni / Au plating) formed at a pitch of 5.5 mm vertically and 5.5 mm horizontally in the mounting area of the IC chip 41, and the cross section has a diameter of 0. .1 mm circular cylindrical shape), as in the case of the alignment mark 31, the anisotropic conductive film 32 is attached and pressed using the metal rod 40 to form the recess 33, An electronic component mounting structure was produced, and the pattern recognition coincidence frequency B was measured.
The pattern recognition coincidence degrees A and B are absolute evaluations (absolute values) calculated using normalized correlation using a flip chip bonder (trade name: FB30T-M, manufactured by Panasonic Corporation).
The light transmittance is obtained by calculating the light transmittance of the anisotropic conductive film having the measured thickness using the measurement result of the thickness of the anisotropic conductive film 32 on the alignment marks 31 and 51. is there. Therefore, the light transmittance before attaching the anisotropic conductive film 32 is 100%.

(実施例2)
実施例1において、円柱形状(底面:直径2mm、高さ:20mm、先端形状が平坦)の金属棒を、円柱形状(底面:直径2mm、高さ:20mm)と半球(直径2mm)とを組み合わせた形状(先端形状が半球状)の金属棒に変更した以外は、実施例1と同様にして、電子部品実装構造体を作製し、異方性導電フィルムの厚みt(μm)、パターン認識一致度数A及びB(%)、光透過率(%)を測定した。
(Example 2)
In Example 1, a cylindrical rod (bottom: 2 mm in diameter, height: 20 mm, tip shape is flat) is combined with a cylindrical shape (bottom: 2 mm in diameter, height: 20 mm) and a hemisphere (2 mm in diameter). An electronic component mounting structure was prepared in the same manner as in Example 1 except that the metal rod was changed to a metal rod having a hemispherical shape (tip shape is hemispherical), and the anisotropic conductive film thickness t 1 (μm), pattern recognition The coincidence frequencies A and B (%) and light transmittance (%) were measured.

(比較例1)
実施例1において、金属棒による押圧を行わなかったこと以外は、実施例1と同様にして、電子部品実装構造体を作製し、異方性導電フィルムの厚みt(μm)、パターン認識一致度数A及びB(%)、光透過率(%)を測定した。
(Comparative Example 1)
In Example 1, an electronic component mounting structure was produced in the same manner as in Example 1 except that pressing with a metal rod was not performed, and the thickness t 0 (μm) of the anisotropic conductive film and pattern recognition coincidence were obtained. The frequencies A and B (%) and light transmittance (%) were measured.

以上より、実施例1及び2でのパターン認識一致度が許容範囲内(70%以上)であることから、アライメントマーク31、51上の異方性導電フィルム32を金属棒40で押圧することにより、フリップチップボンダー(商品名:FB30T−M、パナソニック製)により、アライメントマーク31、51を認識可能であることが判った。
実施例1及び2のように、アライメントマークの直上領域における粒子含有フィルムを押圧すると、該押圧により粒子が押しのけられるため(粒子が押圧方向と同一方向に移動せず、押圧方向と略垂直な方向に移動する)、押圧により薄くなった粒子含有フィルム部分においても、押圧前の粒子含有フィルムにおける粒子密度とほぼ同等な粒子密度で粒子が存在する。よって、粒子含有フィルムが薄くなったことで、アライメントマークの認識がしやすくなり、パターン認識一致度A、Bが向上しているものと考えられる。
また、アライメントマーク31、51を覆う形で、異方性導電フィルム32を基板34の全面に貼り付けが可能となるため、高精度なフィルム貼付け装置を必要とせず、また、接着シート貼付け回数を減らすことができ、もって工程の短縮を図ることができる。
また、図5に示すように、ICチップ41の実装領域内にアライメントマーク51を設置することも可能となり、基板を小型化することができる。
また、先端形状が平坦の金属棒を用いて異方性導電フィルムを押圧した実施例1と、先端形状が半球状の金属棒を用いて異方性導電フィルムを押圧した実施例2とを比較した場合、アライメントマーク上の異方性導電フィルムの厚みtがそれぞれ10μmであっても、実施例2の方が良好なパターン認識一致度(%)を示している。これは、先端形状が半球状の金属棒を用いることにより、形成された凹部の形状が半球状となり、入射光を散乱させて、「てかり」を抑制することができ、パターン認識一致度(%)が向上したものと考えられる。
As mentioned above, since the pattern recognition coincidence in Examples 1 and 2 is within an allowable range (70% or more), by pressing the anisotropic conductive film 32 on the alignment marks 31 and 51 with the metal rod 40. It was found that the alignment marks 31 and 51 can be recognized by a flip chip bonder (trade name: FB30T-M, manufactured by Panasonic).
As in Examples 1 and 2, when the particle-containing film in the region immediately above the alignment mark is pressed, the particles are pushed away by the pressing (the particles do not move in the same direction as the pressing direction, and are substantially perpendicular to the pressing direction). Even in the particle-containing film portion that is thinned by pressing, particles are present at a particle density substantially equal to the particle density in the particle-containing film before pressing. Therefore, it is considered that the alignment marks A and B are improved because the particle-containing film is thinned so that the alignment mark can be easily recognized.
In addition, since the anisotropic conductive film 32 can be applied to the entire surface of the substrate 34 so as to cover the alignment marks 31 and 51, a highly accurate film application device is not required, and the number of times of adhesive sheet application can be increased. Therefore, the process can be shortened.
Further, as shown in FIG. 5, it is possible to install the alignment mark 51 in the mounting area of the IC chip 41, and the substrate can be miniaturized.
Further, Example 1 in which the anisotropic conductive film was pressed using a metal rod having a flat tip shape was compared with Example 2 in which the anisotropic conductive film was pressed using a metal rod having a hemispherical tip shape. In this case, even when the thickness t 1 of the anisotropic conductive film on the alignment mark is 10 μm, Example 2 shows better pattern recognition coincidence (%). This is because by using a metal rod having a hemispherical tip shape, the shape of the formed recess becomes hemispherical, which can scatter incident light and suppress “light”, and the pattern recognition coincidence ( %) Is considered to have improved.

本発明の電子部品実装構造体の製造方法は、例えば、半導体装置などの製造に好適に用いられる。   The method for manufacturing an electronic component mounting structure according to the present invention is suitably used for manufacturing a semiconductor device, for example.
