Description
本発明は、樹脂組成物及び樹脂組成物を使用して作製した半導体装置に関するものである。 The present invention relates to a resin composition and a semiconductor device manufactured using the resin composition.
半導体製品の大容量、高速処理化及び微細配線化に伴い半導体製品作動中に発生する熱の問題が顕著になってきており、半導体製品から熱を逃がす、いわゆるサーマルマネージメントがますます重要な課題となってきている。このため半導体製品にヒートスプレッダー、ヒートシンク等の放熱部材を取り付ける方法等が一般的に採用されているが放熱部材を接着する材料自体の熱伝導率もより高いものが望まれてきている。一方半導体製品の形態によっては半導体素子そのものを金属製のヒートスプレッダーに接着したり、半導体素子を接着したリードフレームのダイパッド部にヒートスプレッダーを接着したり、ダイパッド部がＰＫＧ表面に露出しており放熱板をかねる場合もあり、さらにはサーマルビア等の放熱機構を有する有機基板等に接着したりする場合もある。この場合も同様に半導体素子を接着する材料に高熱伝導率が要求される。このようにダイアタッチペースト又は放熱部材接着用材料に高熱伝導率が要求されているが、同時に半導体製品の基板搭載時のリフロー処理に耐える必要があり、さらには大面積の接着が要求される場合も多く構成部材間の熱膨張係数の違いによる反り等の発生を抑制するため低応力性も併せ持つ必要がある。 The problem of heat generated during the operation of semiconductor products has become more prominent with the increase in capacity, high-speed processing, and fine wiring of semiconductor products. So-called thermal management, which releases heat from semiconductor products, is an increasingly important issue. It has become to. For this reason, a method of attaching a heat radiating member such as a heat spreader or a heat sink to a semiconductor product is generally adopted, but a material having a higher thermal conductivity has been desired. On the other hand, depending on the form of the semiconductor product, the semiconductor element itself is bonded to a metal heat spreader, the heat spreader is bonded to the die pad part of the lead frame to which the semiconductor element is bonded, or the die pad part is exposed on the surface of the PKG. In some cases, the plate may be attached, and further, it may be adhered to an organic substrate having a heat dissipation mechanism such as a thermal via. In this case as well, a high thermal conductivity is required for the material to which the semiconductor element is bonded. In this way, high thermal conductivity is required for die attach paste or heat dissipation member bonding material, but at the same time, it is necessary to withstand reflow processing when mounting a semiconductor product on a substrate, and even when large area bonding is required In order to suppress the occurrence of warpage or the like due to the difference in thermal expansion coefficient between the constituent members, it is necessary to have low stress properties.
ここで通常高熱伝導性接着剤には、銀粉、銅粉といった金属フィラーや窒化アルミ、窒化ボロン等のセラミック系フィラー等を有機系のバインダーに高い含有率で添加するが、含有可能な量に限界があり高熱伝導率が得られない場合、多量の溶剤を含有し硬化物単体の熱伝導率は良好だが半導体製品中では硬化物中に溶剤が残存又は揮発した後がボイドになり熱伝導率が安定しない。また、高フィラー含有率に基づき弾性率が高く低応力性が不十分な場合等満足なものはなかった（例えば特許文献１参照）。
本発明は、弾性率が低く十分な低応力性を有する樹脂組成物及び該樹脂組成物を半導体用ダイアタッチペースト又は放熱部材接着用材料として使用することで耐リフロー性等の信頼性に優れた半導体装置を提供することである。 The present invention is excellent in reliability such as reflow resistance by using a resin composition having a low elastic modulus and sufficiently low stress, and using the resin composition as a die attach paste for a semiconductor or a material for adhering a heat dissipation member.

本発明は、カルボキシ基を有する（メタ）アクリル酸エステル化合物、マレイミド基を有する化合物、熱ラジカル重合開始剤、及び充填材を含む樹脂組成物であって、弾性率が低く接着性に優れる樹脂組成物を提供するものである。
以下、本発明について詳細に説明する。
The present invention is a resin composition comprising a (meth) acrylic acid ester compound having a carboxy group, a compound having a maleimide group, a thermal radical polymerization initiator, and a filler, and having a low elastic modulus and excellent adhesiveness It provides things.
Hereinafter, the present invention will be described in detail.
本発明では、カルボキシ基を有する（メタ）アクリル酸エステル化合物（Ａ）を使用する。一般にモノ（メタ）アクリレート、ジ（メタ）アクリレートなどの低粘度アクリルエステル化合物は反応性の希釈剤として使用されているが、カルボキシ基を有する（メタ）アクリル酸エステル化合物（Ａ）を使用することにより特に良好な接着性を示すことが可能となる。（メタ）アクリル酸もカルボキシ基を有するが、樹脂組成物として使用する場合に通常ダイボンダー等の装置を用いて塗布し、加熱硬化を行うため塗布作業時及び硬化時の臭気、ならびに皮膚刺激性の問題より使用できない。カルボキシ基を有する（メタ）アクリル酸エステル化合物であれば特に限定されるわけではないが、水酸基を有する（メタ）アクリル酸エステル化合物とジカルボン酸を反応させた化合物が好ましい。より好ましくは２−ヒドロキシエチル（メタ）アクリレートとジカルボン酸とを反応させた化合物であり、好ましいジカルボン酸としてはコハク酸、シクロヘキサンジカルボン酸及びこれらの誘導体を反応させた化合物である。反応の容易性の観点からも２−ヒドロキシエチル（メタ）アクリレートと無水コハク酸又はシクロヘキサンジカルボン酸無水物との反応物は特に好ましい。 In this invention, the (meth) acrylic acid ester compound (A) which has a carboxy group is used. Generally, low-viscosity acrylic ester compounds such as mono (meth) acrylate and di (meth) acrylate are used as reactive diluents, but use a (meth) acrylic ester compound (A) having a carboxy group. This makes it possible to exhibit particularly good adhesiveness. (Meth) acrylic acid also has a carboxy group, but when it is used as a resin composition, it is usually applied using a device such as a die bonder, and is cured by heating. It cannot be used because of problems. Although it will not specifically limit if it is the (meth) acrylic acid ester compound which has a carboxy group, The compound which made the (meth) acrylic acid ester compound and dicarboxylic acid which have a hydroxyl group react is preferable. More preferred are compounds obtained by reacting 2-hydroxyethyl (meth) acrylate and dicarboxylic acid, and preferred dicarboxylic acids are compounds obtained by reacting succinic acid, cyclohexanedicarboxylic acid and derivatives thereof. A reaction product of 2-hydroxyethyl (meth) acrylate and succinic anhydride or cyclohexanedicarboxylic anhydride is particularly preferable from the viewpoint of easy reaction.
本発明では、室温で液状の化合物であるマレイミド基を有する化合物（Ｂ）を使用する。マレイミド基を有する化合物（Ｂ）は、化合物（Ａ）と共重合可能であるとともに弾性率の低い硬化物を得るために必要である。 In the present invention, a compound (B) having a maleimide group that is a liquid compound at room temperature is used. The compound (B) having a maleimide group is necessary for obtaining a cured product that is copolymerizable with the compound (A) and has a low elastic modulus.
室温で液状のマレイミド基を有する化合物（Ｂ）は、後述の熱ラジカル開始剤（Ｃ）とともに使用することで、加熱下良好な反応性を示すとともにイミド環の有する極性により例えば、銀メッキ、Ｎｉ−Ｐｄメッキといった難接着性の金属表面に対しても良好な接着性を示すことは良く知られているが、１官能の場合には期待する接着力向上効果が十分でなく、３官能以上の場合には分子量が大きくなり樹脂組成物の高粘度化につながるため２官能の化合物が好適に使用される。ここで２官能のマレイミド化合物としては芳香族アミンを原料とするものが良く知られているが、一般に芳香族系のマレイミドは結晶性が強いため室温で液状のものを得ることが難しい。またこのようなマレイミド化合物はジメチルホルムアミド、Ｎ−メチルピロリドンといった高沸点の極性溶媒には可溶であるが、このような溶媒を使用した場合には、樹脂組成物の加熱硬化の際にボイドが発生し、熱伝導性を悪化させるので使用できない。
また芳香族環の存在により分子間の相互作用が強くなるため弾性率が高く、脆い硬化物となる傾向にあるので好ましくない。
そこでマレイミド基を有する化合物（Ｂ）としては、炭素数１以上、６以下のアミノ酸をマレイミド化したマレイミドアミノ酸と分子内に水酸基を２つ以上有する化合物とのエステル化化合物であることが好ましい。アミノ酸の炭素数が１以上、６以下である場合にはジオールとの反応により液状のビスマレイミド化合物を容易に得ることができるので好適であり、なかでも炭素数１の場合と炭素数６の場合が好ましい。前記ジオールとして好ましいのは分子量が２００以上、５０００以下の場合であり、さらに好ましいのはポリエーテルジオール、ポリエステルジオール、ポリカーボネートジオールから選ばれる少なくとも１種である場合である。最も好ましいのは前記ジオールの分子量が２００以上、２０００以下のポリエーテルジオール、ポリエステルジオール、ポリカーボネートジオールから選ばれる少なくとも１種の場合である。ポリエーテルジオール、ポリエステルジオール、ポリカーボネートジオールから選ばれる少なくとも１種を用いることでより低弾性率の硬化物を得ることが可能となるとともに、室温で液状であるため後述の充填剤（Ｄ）と配合しても低粘度で硬化性に優れる樹脂組成物を得ることが可能となる。
The compound (B) having a maleimide group which is liquid at room temperature, when used with the thermal radical initiator (C) described later, exhibits good reactivity under heating and, for example, silver plating, Ni depending on the polarity of the imide ring -It is well known that it exhibits good adhesion even on hard-to-adhere metal surfaces such as Pd plating. In some cases, a bifunctional compound is preferably used because the molecular weight increases and the viscosity of the resin composition increases. Here, as a bifunctional maleimide compound, those using an aromatic amine as a raw material are well known, but generally, an aromatic maleimide has a strong crystallinity, so that it is difficult to obtain a liquid at room temperature. Such maleimide compounds are soluble in high-boiling polar solvents such as dimethylformamide and N-methylpyrrolidone. However, when such a solvent is used, voids are not formed during heat curing of the resin composition. Generated and deteriorates thermal conductivity, and cannot be used.
Further, since the interaction between molecules becomes strong due to the presence of the aromatic ring, the elastic modulus is high and it tends to be a brittle cured product.
Therefore, the compound (B) having a maleimide group is preferably an esterified compound of a maleimide amino acid obtained by maleimidating an amino acid having 1 to 6 carbon atoms and a compound having two or more hydroxyl groups in the molecule. When the amino acid has 1 to 6 carbon atoms, it is preferable because a liquid bismaleimide compound can be easily obtained by reaction with a diol, and in particular, the case of 1 and 6 carbon atoms. Is preferred. Preferred as the diol is a molecular weight of 200 or more and 5000 or less, and more preferred is a case where it is at least one selected from polyether diol, polyester diol, and polycarbonate diol. Most preferred is the case where the diol has a molecular weight of 200 or more and 2000 or less, and is at least one selected from polyether diol, polyester diol, and polycarbonate diol. By using at least one selected from polyether diol, polyester diol and polycarbonate diol, it becomes possible to obtain a cured product having a lower elastic modulus, and since it is liquid at room temperature, it is blended with a filler (D) described later. Even in this case, a resin composition having a low viscosity and excellent curability can be obtained.
本発明では熱ラジカル重合開始剤（Ｃ）を使用する。通常熱ラジカル重合開始剤として用いられるものであれば特に限定しないが、望ましいものとしては、急速加熱試験（試料１ｇを電熱板の上にのせ、４℃／分で昇温した時の分解開始温度）における分解温度が４０〜１４０℃となるものが好ましい。分解温度が４０℃未満だと、樹脂組成物の常温における保存性が悪くなり、１４０℃を越えると硬化時間が極端に長くなるため好ましくない。 In the present invention, a thermal radical polymerization initiator (C) is used. Although it is not particularly limited as long as it is normally used as a thermal radical polymerization initiator, it is desirable that a rapid heating test (decomposition start temperature when a sample is placed on an electric heating plate and heated at 4 ° C./min. In which the decomposition temperature is 40 to 140 ° C. If the decomposition temperature is less than 40 ° C., the preservability of the resin composition at normal temperature deteriorates, and if it exceeds 140 ° C., the curing time becomes extremely long, which is not preferable.

Although not particularly limited, it is preferably contained in the resin composition in an amount of 0.001 to 2% by weight.
本発明の樹脂組成物は、通常蛍光灯等の照明下で使用されるので光重合開始剤が含まれていると使用中に反応により粘度上昇が観察されるため実質的に光開始剤を含有することはできない。実質的にとは、粘度上昇が観察されない程度で光重合開始剤が微量に存在してもよく、好ましくは、含有しないことである。 Since the resin composition of the present invention is usually used under illumination such as a fluorescent lamp, it contains a photoinitiator because a viscosity increase is observed due to reaction during use when a photopolymerization initiator is included. I can't do it. “Substantially” means that a small amount of the photopolymerization initiator may be present to such an extent that no increase in viscosity is observed, and it is preferably not contained.
本発明では充填材（Ｄ）として、銀粉、金粉、銅粉、アルミニウム粉、ニッケル粉、パラジウム粉といった金属粉、アルミナ粉末、チタニア粉末、アルミニウムナイトライド粉末、ボロンナイトライド粉末といったセラミック粉末、ポリエチレン粉末、ポリアクリル酸エステル粉末、ポリテトラフルオロエチレン粉末、ポリアミド粉末、ポリウレタン粉末、ポリシロキサン粉末といった高分子粉末を使用可能である。樹脂組成物を使用する際にはノズルを使用して吐出する場合があるので、ノズル詰まりを防ぐために平均粒径は３０μｍ以下が好ましく、ナトリウム、塩素といったイオン性の不純物が少ないことが好ましい。特に導電性、熱伝導性が要求される場合には銀粉を使用することが好ましい。通常電子材料用として市販されている銀粉であれば、還元粉、アトマイズ粉等が入手可能で、好ましい粒径としては平均粒径が１μｍ以上、３０μｍ以下である。これ以下では樹脂組成物の粘度が高くなりすぎ、これ以上では上述のようにディスペンス時にノズル詰まりの原因となりうるからであり、電子材料用以外の銀粉ではイオン性不純物の量が多い場合があるので注意が必要である。形状はフレーク状、球状等特に限定されないが、好ましくはフレーク状のものを使用し、通常樹脂組成物中７０重量％以上、９５重量％以下含まれる。銀粉の割合がこれより少ない場合には導電性が悪化し、これより多い場合には樹脂組成物の粘度が高くなりすぎるためである。 In the present invention, as filler (D), metal powder such as silver powder, gold powder, copper powder, aluminum powder, nickel powder and palladium powder, ceramic powder such as alumina powder, titania powder, aluminum nitride powder and boron nitride powder, polyethylene powder Polymer powders such as polyacrylate powder, polytetrafluoroethylene powder, polyamide powder, polyurethane powder, and polysiloxane powder can be used. When the resin composition is used, it may be discharged using a nozzle. Therefore, in order to prevent nozzle clogging, the average particle size is preferably 30 μm or less, and it is preferable that there are few ionic impurities such as sodium and chlorine. In particular, silver powder is preferably used when electrical conductivity and thermal conductivity are required. If it is the silver powder currently marketed for electronic materials normally, reduced powder, atomized powder, etc. can be obtained, and as an average particle diameter, an average particle diameter is 1 micrometer or more and 30 micrometers or less. Below this, the viscosity of the resin composition becomes too high, and above this can cause nozzle clogging during dispensing as described above, and silver powder other than for electronic materials may have a large amount of ionic impurities. Caution must be taken. The shape is not particularly limited, such as flaky shape or spherical shape, but preferably flaky shape is used, and it is usually contained in the resin composition in an amount of 70% by weight to 95% by weight. This is because when the proportion of silver powder is less than this, the conductivity deteriorates, and when it is more than this, the viscosity of the resin composition becomes too high.
