Description
本発明は、導電性樹脂組成物および半導体装置に関する。 The present invention relates to a conductive resin composition and a semiconductor device.
従来、銅などのリードフレーム上にIC、LSIなどの半導体素子をダイボンディングするための材料として、たとえば金属粒子を含有する導電性樹脂組成物の開発が進められている。当該導電性樹脂組成物に要求される主な特性としては、導電性と熱伝導性がある。たとえば、特許文献1には、プレート型銀微粒子を焼結することで、通常の銀粉のみを充填した場合よりも熱伝導率を向上させることができることが記載されている。 BACKGROUND ART Conventionally, conductive resin compositions containing, for example, metal particles have been developed as materials for die-bonding semiconductor elements such as ICs and LSIs onto lead frames made of copper or the like. The main properties required of the conductive resin composition include electrical conductivity and thermal conductivity. For example, Patent Document 1 describes that by sintering plate-shaped fine silver particles, the thermal conductivity can be improved more than when only ordinary silver powder is filled.
近年、リードフレームにディスペンスした導電性樹脂組成物に含まれる樹脂の滲み出し現象(EBO(エポキシブリードアウト)という)が問題となっている。EBOが発生すると、導電性樹脂組成物の密着性が低下し、ひいては半導体パッケージの信頼性低下の要因となる。そこで、EBOの対策として、リードフレーム上にEBO防止剤と呼ばれる表面処理層を形成する場合がある。
EBO防止剤が表面に設けられたリードフレームに半導体素子をダイボンディングする場合に、EBO防止剤で構成される表面処理層が介在することにより、リードフレームと半導体素子との間の剥離強度が低下するという課題が新たに生じる。しかし、従来技術では、このような課題が未解決のままであり、導電性樹脂組成物に関して開発の余地が残されている。
本発明は、このような事情を鑑みなされたものであり、半導体素子をEBO防止剤で表面処理が施された金属フレームに接着したときの剥離強度を向上させることができる導電性樹脂組成物を提供する。
In recent years, a phenomenon in which resin contained in a conductive resin composition dispensed onto a lead frame oozes out (referred to as EBO (epoxy bleed out)) has become a problem. When EBO occurs, the adhesion of the conductive resin composition decreases, which in turn causes a decrease in the reliability of the semiconductor package. Therefore, as a countermeasure against EBO, a surface treatment layer called an EBO inhibitor may be formed on the lead frame.
When die bonding a semiconductor element to a lead frame with an EBO inhibitor on its surface, the presence of a surface treatment layer made of the EBO inhibitor reduces the peel strength between the lead frame and the semiconductor element. A new issue arises: However, in the prior art, such problems remain unsolved, and there is still room for development regarding conductive resin compositions.
The present invention was made in view of these circumstances, and provides a conductive resin composition that can improve the peel strength when a semiconductor element is bonded to a metal frame whose surface has been treated with an EBO inhibitor. provide.
本発明によれば、Ag粒子(A)と、ベース樹脂(B)と、ラジカル開始剤(C)と、を含み、前記ラジカル開始剤(C)の10時間半減期温度が100℃以上120℃以下である、導電性樹脂組成物が提供される。 According to the present invention, the invention includes Ag particles (A), a base resin (B), and a radical initiator (C), and the radical initiator (C) has a 10-hour half-life temperature of 100°C or more and 120°C. The following conductive resin compositions are provided.
また、本発明によれば、Ag粒子(A)と、ベース樹脂(B)と、窒素含複素環化合物(E)と、を含む導電性樹脂組成物が提供される。 Further, according to the present invention, there is provided a conductive resin composition containing Ag particles (A), a base resin (B), and a nitrogen-containing heterocyclic compound (E).
また、本発明によれば、上述した導電性樹脂組成物の硬化物を有する半導体装置が提供される。 Further, according to the present invention, a semiconductor device having a cured product of the above-mentioned conductive resin composition is provided.
本発明によれば、半導体素子をEBO防止剤で表面処理が施された金属フレームに接着したときの剥離強度を向上させることができる。 According to the present invention, it is possible to improve the peel strength when a semiconductor element is bonded to a metal frame whose surface has been treated with an EBO inhibitor.
上述した目的、およびその他の目的、特徴および利点は、以下に述べる好適な実施の形態、およびそれに付随する以下の図面によってさらに明らかになる。 The above-mentioned objects, and other objects, features, and advantages will become more apparent from the preferred embodiments described below and the accompanying drawings.
以下、本発明の実施形態について、詳細に説明する。なお、本明細書中、数値範囲の説明における「a~b」との表記は、特に断らない限り、a以上b以下であることを表す。 Embodiments of the present invention will be described in detail below. In addition, in this specification, the notation "a to b" in the description of numerical ranges represents a range from a to b, unless otherwise specified.
以下に説明する導電性樹脂組成物は、EBO防止剤で表面処理が施されたリードフレームなどの配線部材に半導体素子をダイボンディングする際の材料として好適に利用される。 The conductive resin composition described below is suitably used as a material for die bonding a semiconductor element to a wiring member such as a lead frame whose surface has been treated with an EBO inhibitor.
(実施形態1)
実施形態1に係る導電性樹脂組成物は、Ag粒子(A)と、ベース樹脂(B)と、ラジカル開始剤(C)と、を含む。ラジカル開始剤(C)の10時間半減期温度は100℃以上120℃以下である。以下、本実施形態の導電性樹脂組成物の各成分について説明する。なお、以下の説明において、導電性樹脂組成物全体に対する含有量とは、後述する溶媒を除く成分の合計質量に対する各成分の質量の割合を指す。
(Embodiment 1)
The conductive resin composition according to Embodiment 1 includes Ag particles (A), a base resin (B), and a radical initiator (C). The 10-hour half-life temperature of the radical initiator (C) is 100°C or more and 120°C or less. Each component of the conductive resin composition of this embodiment will be explained below. In addition, in the following description, content with respect to the whole electrically conductive resin composition refers to the ratio of the mass of each component to the total mass of components excluding the solvent mentioned later.
(Ag粒子(A))
本実施形態の導電性樹脂組成物に含まれるAg粒子(A)は、導電性樹脂組成物に対して熱処理することによりシンタリングを起こして粒子連結構造を形成する。すなわち、導電性樹脂組成物を加熱して得られる硬化物において、Ag粒子(A)同士は互いに融着して存在する。
これにより、導電性樹脂組成物を加熱して得られる硬化物について、リードフレームなどの配線部材や半導体素子に対する密着性および導電性を向上させることができる。
なお、配線部材の表面に、EBO防止剤が塗布されている場合には、導電性樹脂組成物に含まれるAg粒子(A)がEBO防止剤で構成される表面処理層を突き破り、配線部材に達する。これにより、EBOを抑制しつつ、配線部材と半導体素子との間の導電性を良好にすることができる。
(Ag particles (A))
The Ag particles (A) contained in the conductive resin composition of this embodiment undergo sintering by heat-treating the conductive resin composition to form a particle-linked structure. That is, in the cured product obtained by heating the conductive resin composition, the Ag particles (A) exist fused to each other.
Thereby, the adhesiveness and conductivity of the cured product obtained by heating the conductive resin composition to wiring members such as lead frames and semiconductor elements can be improved.
In addition, when the surface of the wiring member is coated with an EBO inhibitor, the Ag particles (A) contained in the conductive resin composition break through the surface treatment layer composed of the EBO inhibitor, and the wiring member is coated with an EBO inhibitor. reach Thereby, it is possible to improve the conductivity between the wiring member and the semiconductor element while suppressing EBO.
Ag粒子(A)の形状は、特に限定されないが、たとえば球状、フレーク状、および鱗片状等を挙げることができる。本実施形態においては、Ag粒子(A)が球状粒子を含むことがより好ましい。これにより、Ag粒子(A)の焼結性を向上させることができる。また、シンタリングの均一性の向上にも寄与することができる。
また、コストを低減させる観点からは、Ag粒子(A)がフレーク状粒子を含む態様を採用することもできる。さらには、コストの低減とシンタリングの均一性のバランスを向上させる観点から、Ag粒子(A)が球状粒子とフレーク状粒子の双方を含んでいてもよい。
The shape of the Ag particles (A) is not particularly limited, and examples include spherical, flaky, and scaly shapes. In this embodiment, it is more preferable that the Ag particles (A) include spherical particles. Thereby, the sinterability of the Ag particles (A) can be improved. Moreover, it can also contribute to improving the uniformity of sintering.
Moreover, from the viewpoint of reducing costs, it is also possible to employ an embodiment in which the Ag particles (A) include flaky particles. Furthermore, from the viewpoint of reducing cost and improving the balance between sintering uniformity, the Ag particles (A) may include both spherical particles and flake particles.
