Description

本発明は、一括封止型半導体装置の樹脂封止方法に関するものである。ここでいう一括封止型半導体装置とは、半導体の集合基板を樹脂封止した後に切断し個々の半導体装置を製造する方法の総称であり、MAP(モールドアレイパッケージ)、BGA(ボールグリッドアレイ)、CSP(チップスケールパッケージ)、WLP(ウエハーレベルパッケージ)、NLP(ノンリードタイプパッケージ)等で呼ばれる半導体装置を示す。   The present invention relates to a resin sealing method for a batch sealing type semiconductor device. The collective sealing type semiconductor device here is a general term for a method for manufacturing individual semiconductor devices by sealing a semiconductor collective substrate after resin sealing, and MAP (mold array package) and BGA (ball grid array). , A semiconductor device called CSP (chip scale package), WLP (wafer level package), NLP (non-lead type package) or the like.

情報通信分野に於ける急速な技術進歩に呼応して、電子機器の性能向上、小型軽量化及び低コスト化が強く求められ、電子機器の心臓部である半導体装置及びその搭載基板の高集積高密度化が必須のものとなっている。この要求は大面積基板を一括して樹脂封止する製法案を生み出し、電気接続部材や半導体構成単位の違い等により様々な呼び方がされている。大きく分類すると、基板に半導体素子を高密度搭載する方法と、半導体素子の集合体と基板を結合する方法の2つである。これらの製法は理論的には従来の製造方法に比べて効率面で優れる事は言うまでもない。基板や樹脂等の素部材の使用量を少なくできる、金型の寸法を小さく且つ種類を少なくできる等の利点が多い。
特開2001−007259号公報
In response to rapid technological advancements in the information and communication field, there is a strong demand for improved performance, small size, light weight, and low cost of electronic devices. High integration and high integration of semiconductor devices and their mounting boards are the heart of electronic devices. Densification is essential. This requirement has created a manufacturing method that encapsulates a large-area substrate in a lump, and has been called variously due to differences in electrical connection members and semiconductor structural units. Broadly speaking, there are two methods: a method of mounting semiconductor elements on a substrate at a high density, and a method of combining an assembly of semiconductor elements and a substrate. It goes without saying that these production methods are theoretically superior in efficiency compared to conventional production methods. There are many advantages such as a reduction in the amount of the substrate and resin used, and a reduction in the size and type of the mold.

しかしながら、これらの一括封止技術は今迄の検討努力にも拘わらず汎用化には至っていない。樹脂封止時に大きな反りを生じ個別の半導体装置に切断することが困難である等の問題を抱えているためである。即ち、実用性や工業性といった面での技術検討が不十分であり未だに提案段階と呼ぶべき状態のままである。   However, these collective sealing technologies have not been widely used in spite of the efforts made so far. This is because there is a problem that a large warp occurs during resin sealing and it is difficult to cut into individual semiconductor devices. That is, technical studies in terms of practicality and industriality are insufficient, and it still remains to be called the proposal stage.

通常、一括封止型半導体装置は150℃以上の温度で樹脂組成物を充填硬化し封止される。これが室温に冷却される時に寸法収縮の大きな樹脂側に曲がるため反り問題を生じるのである。従来の封止方法でこの問題を解決するためには樹脂の熱伸縮特性を抜本的に変更すること、基板類と同等にするかゴム状にすることが必要である。しかし、いずれも大きな技術課題、例えば、前者は無機物の配合量が多くなるため充填性が困難になる、後者は樹脂強度が不足し半導体素子を保護できなくなるといった問題を有している。   Usually, the encapsulated semiconductor device is filled and cured with a resin composition at a temperature of 150 ° C. or higher and sealed. When this is cooled to room temperature, it bends to the side of the resin with large dimensional shrinkage, causing a warpage problem. In order to solve this problem with a conventional sealing method, it is necessary to drastically change the thermal expansion / contraction characteristics of the resin, to make it equivalent to a substrate or to make it rubbery. However, both of them have big technical problems, for example, the former has a problem that filling amount becomes difficult because the amount of the inorganic compound is increased, and the latter has a problem that the semiconductor element cannot be protected due to insufficient resin strength.

本発明は、超低熱膨張の樹脂組成物を用いて垂直に押圧硬化させる一括封止型半導体装置の樹脂封止方法である。   The present invention is a resin sealing method of a batch sealing type semiconductor device in which a resin composition having an ultra-low thermal expansion is pressed and cured vertically.

即ち、金型の片方に一括封止型半導体の基板を、他の一方に半固形状のエポキシ樹脂組成物を配置し、圧縮成形法にて加熱硬化させることを特徴とする半導体装置の樹脂封止方法である。   That is, a resin package for a semiconductor device, characterized in that a batch-sealed semiconductor substrate is placed on one side of a mold and a semi-solid epoxy resin composition is placed on the other side and heat-cured by compression molding. It is a stopping method.

請求項2は、樹脂組成物を予め剥離紙に塗布した積層材料の形で使用する、又は予め金型の一方に充填して使用することを特徴とする樹脂封止方法である。   According to a second aspect of the present invention, there is provided a resin sealing method wherein the resin composition is used in the form of a laminated material preliminarily applied to a release paper, or is previously filled in one mold.

請求項3は、前記エポキシ樹脂組成物を予め金型の一方に充填して使用することを特徴とする樹脂封止方法である。   A third aspect of the present invention is a resin sealing method in which the epoxy resin composition is filled in one of molds in advance.

請求項4は、シリカを93重量%以上含み、液状又は低温溶融型の樹脂類(エポキシ樹脂、硬化剤)、硬化促進剤及びその他の添加剤等で構成されるエポキシ樹脂組成物を用いることを特徴とする樹脂封止方法である。   Claim 4 is to use an epoxy resin composition containing 93% by weight or more of silica and comprising liquid or low-melting type resins (epoxy resin, curing agent), a curing accelerator and other additives. It is the resin sealing method characterized.

請求項5は、粒径75μm以下の球状シリカ、液状または固形のエポキシ樹脂及び酸無水物またはフェノール樹脂を主成分として構成されるエポキシ樹脂組成物を用いることを特徴とする樹脂封止方法である。   Claim 5 is a resin sealing method characterized by using an epoxy resin composition composed mainly of spherical silica having a particle size of 75 μm or less, liquid or solid epoxy resin, and acid anhydride or phenol resin. .

請求項6は、前記エポキシ樹脂組成物の中央が凸状の形状であることを特徴とする樹脂封止方法である。   A sixth aspect of the present invention is a resin sealing method, wherein the center of the epoxy resin composition has a convex shape.

請求項7は、前記エポキシ樹脂組成物に切り込みを設けたことを特徴とする樹脂封止方法である。   A seventh aspect of the present invention is a resin sealing method in which a cut is provided in the epoxy resin composition.

請求項8は、前記切り込みが格子状に設けられていることを特徴とする樹脂封止方法である。   An eighth aspect of the present invention is a resin sealing method, wherein the cuts are provided in a lattice shape.

請求項9は、前記切り込みがほぼV字型の形状をしていることを特徴とする樹脂封止方法である。   According to a ninth aspect of the present invention, there is provided a resin sealing method, wherein the cut has a substantially V-shaped shape.

請求項12は、前記ブロックが隣り合うブロックの間に隙間をいれて配置されていることを特徴とする樹脂封止方法である。   A twelfth aspect of the present invention is a resin sealing method, wherein the blocks are arranged with a gap between adjacent blocks.

一般的に、低熱膨張の樹脂組成物は無機充填材を多量に含有するため流動性が極めて乏しいという欠点を有する。よって、最小距離で充填する圧縮成形法で樹脂封止することが必要であり、これにより従来の滴下法や移送成形法で指摘された未充填や金線変形等の問題が解決できる。又、圧縮成形を採用すると、移送成形や射出成形で問題となる材料損失(ランナーやスプルー)が解決できるという利点もある。   Generally, a resin composition having low thermal expansion has a drawback that it has extremely poor fluidity because it contains a large amount of an inorganic filler. Therefore, it is necessary to seal the resin by a compression molding method that fills at a minimum distance, and this can solve problems such as unfilling and gold wire deformation pointed out by the conventional dropping method and transfer molding method. In addition, when compression molding is employed, there is an advantage that material loss (runner or sprue) which is a problem in transfer molding or injection molding can be solved.

樹脂組成物は予熱性や充填性の面より半固形状が好ましい。半固形状の樹脂組成物は剥離紙に塗布しシート状やテープ状で取扱うのが容易である。又、成形時に金型に充填し使用することもできる。   The resin composition is preferably semi-solid in terms of preheating and filling properties.

It is preferable to mix. As the silica, spherical products not containing coarse particles, and spherical silica having a particle size of 75 μm or less, particularly 54 μm or less are preferable. Isotropic fine silica does not generate local stress, has good filling properties, and can increase the silica content in the composition. Examples of manufacturers of spherical silica having these characteristics include Electrochemical Industry, Micron, Tatsumori, Tokuyama, and Toagosei.

半導体素子の封止材料としては、実績のあるエポキシ樹脂組成物が好ましい。又、樹脂含有量を少なくし熱膨張率を低くするには、液状又は低融点(融点又は軟化点が80℃以下、特に65℃以下)のエポキシ樹脂及び硬化剤を使用することが好ましい。エポキシ樹脂としてはビスフェノール系(A型、F型等)、複素環系(TEPIC等)、多官能系(EPPN−501等)が好ましい。又、硬化剤としては液状酸無水物(Me−THPA、Me−HHPA、MHAC等)が好ましい。   As a sealing material for a semiconductor element, a proven epoxy resin composition is preferable. In order to reduce the resin content and lower the coefficient of thermal expansion, it is preferable to use a liquid or low melting point (melting point or softening point of 80 ° C. or less, particularly 65 ° C. or less) and a curing agent.
