Abstract
Description
本発明は、封止用エポキシ樹脂組成物、並びに半導体装置及びその製造方法に関する。 The present invention relates to an epoxy resin composition for sealing, a semiconductor device, and a manufacturing method thereof.
電子機器の小型・薄型化による高密度実装の要求が、近年、急激に増加している。このため、半導体パッケージは、従来のピン挿入型に代わり、高密度実装に適した表面実装型が主流になっている。この表面実装型は、リードをプリント基板等に直接はんだ付けする。実装時の加熱方法としては、赤外線リフロー、ベーパーフェーズリフロー、はんだディップ等があり、これらの加熱方法では、パッケージ全体を加熱して半導体が実装される。 In recent years, the demand for high-density packaging due to the miniaturization and thinning of electronic devices has increased rapidly. For this reason, the surface mount type suitable for high-density mounting is the mainstream of the semiconductor package instead of the conventional pin insertion type. In this surface mount type, the lead is soldered directly to a printed circuit board or the like. As a heating method at the time of mounting, there are infrared reflow, vapor phase reflow, solder dipping and the like. In these heating methods, the entire package is heated to mount the semiconductor.
表面実装型のうち、片面樹脂封止型パッケージでは、その形状が片面封止であるために、封止樹脂、基板等のパッケージ構成部材間の線膨張係数の差、弾性率の差等によって発生する熱応力による反りが発生し、搬送性の低下、リフロー工程時の実装信頼性の低下等の問題を引き起こしている。 Among surface mount types, single-sided resin-encapsulated packages have a single-sided shape, which is caused by differences in linear expansion coefficient and elastic modulus between package components such as sealing resin and substrates. Warpage due to thermal stress is generated, causing problems such as a decrease in transportability and a decrease in mounting reliability during the reflow process.
このことから、封止樹脂、基板等のパッケージ構成部材間の線膨張係数の差、弾性率の差等によって発生する熱応力の低減化が要望されている。特に、最近の半導体パッケージでは、封止樹脂層の厚みが薄いパッケージが増えつつある。このため、半導体素子の上部側に封止樹脂層が形成されているパッケージ形態において、常温時に上方に反り（以下、「Ｃｒｙ反り」という。）が発生し、リフロー時に下方に反り（以下、「Ｓｍｉｌｅ反り」という。）が発生する傾向にある。 For this reason, reduction of thermal stress generated by differences in linear expansion coefficients, elastic moduli, etc. between package constituent members such as sealing resins and substrates is desired. In particular, in recent semiconductor packages, an increasing number of packages have a thin sealing resin layer. For this reason, in the package form in which the sealing resin layer is formed on the upper side of the semiconductor element, warping occurs upward (hereinafter referred to as “Cry warping”) at room temperature, and warping downward (hereinafter referred to as “Cry warping”). "Smil warp").
そのため、加熱時のパッケージ収縮量を増加させ、基板によるＣｒｙ反りを抑制し、リフロー時の加熱下におけるパッケージの信頼性を向上させることが強く要求されている。そこで、例えば、反りを低減するために充填剤量を増加することによって、熱膨張率を低減し、反りを抑制する検討が進められている（特許文献１参照）。しかし、充填剤量の増加には限界があり、曲げ弾性率の低下によって、実装時にクラックが発生することがある。 Therefore, there is a strong demand for increasing the package shrinkage during heating, suppressing Cry warping due to the substrate, and improving the reliability of the package under heating during reflow. Therefore, for example, studies are being made to reduce the coefficient of thermal expansion and suppress warpage by increasing the amount of filler in order to reduce warpage (see Patent Document 1). However, there is a limit to the increase in the amount of filler, and cracks may occur during mounting due to a decrease in flexural modulus.
また、半導体装置の小型化・薄型化には半導体素子の厚みを薄くすることが求められるが、半導体素子の薄型化が進むにつれて、半導体素子に対する熱応答挙動の影響（反り、膨張等）が大きくなってくる。これは一般的に基板等の熱膨張係数の方が、半導体素子の熱膨張係数よりも大きいことに起因する。特に、半導体素子と基板とを接続するはんだバンプ等の接続部材には半導体素子及び基板の熱応答挙動の相違に起因する応力が集中しやすく、場合によっては接合部に破断が生じることがある。 Further, in order to reduce the size and thickness of a semiconductor device, it is required to reduce the thickness of the semiconductor element. However, as the semiconductor element becomes thinner, the influence of the thermal response behavior (warping, expansion, etc.) on the semiconductor element increases. It becomes. This is because the coefficient of thermal expansion of the substrate or the like is generally larger than the coefficient of thermal expansion of the semiconductor element. In particular, stresses due to differences in the thermal response behavior of the semiconductor element and the substrate tend to concentrate on the connection member such as a solder bump that connects the semiconductor element and the substrate, and in some cases, the joint may be broken.
本発明は、このような事情に基づいてなされたものであり、半導体素子と基板との熱応答挙動の差を緩和するため、成形温度時に高い収縮率を有する硬化物を形成することができる封止用エポキシ樹脂組成物を提供することを目的とする。また、反りが低減された半導体装置及びその製造方法を提供することを目的とする。 The present invention has been made based on such circumstances, and in order to alleviate the difference in the thermal response behavior between the semiconductor element and the substrate, a sealed product capable of forming a cured product having a high shrinkage rate at the molding temperature.
