Description
本発明は、仮固定に適した光硬化性組成物に関するものである。 The present invention relates to a photocurable composition suitable for temporary fixing.
特許文献1には、ウェハ等の切削・研磨等の作業工程を行う用途に適している光硬化性組成物が記載されている。ウェハ等としては、シリコーンウェハ、サファイアガラス、セラミックス材料、光学用ガラス、水晶、磁性材料などが想定される。一般的に、アクリル系組成物は硬化収縮率が高く、ウェハ等を仮固定する際には硬化収縮によりウェハ等がゆがむことが想定される。一方、特許文献2の発明は可塑剤を添加して、硬化収縮率を下げる試みがなされ、硬化性樹脂と可塑剤の比率において、可塑剤が多く添加されればその分硬化収縮率が下がる。しかしながら、硬化性樹脂は硬化することで分子量が増大していくため、可塑剤が分離して硬化物表面ににじみ出てくる等のブリードアウト現象が発生し易くなる。そのため、硬化性樹脂と可塑剤の種類の選択と添加量に制限が発生する。 Patent Document 1 describes a photocurable composition that is suitable for use in performing work processes such as cutting and polishing of wafers and the like. As the wafer or the like, a silicone wafer, sapphire glass, ceramic material, optical glass, crystal, magnetic material, or the like is assumed. In general, an acrylic composition has a high cure shrinkage rate, and when temporarily fixing a wafer or the like, it is assumed that the wafer or the like is distorted by cure shrinkage. On the other hand, in the invention of Patent Document 2, an attempt is made to lower the curing shrinkage rate by adding a plasticizer. If a larger amount of plasticizer is added in the ratio between the curable resin and the plasticizer, the curing shrinkage rate is lowered accordingly. However, since the molecular weight of the curable resin increases as it hardens, a bleedout phenomenon such as separation of the plasticizer and bleeding into the surface of the cured product is likely to occur. For this reason, there are limitations on the selection and addition amount of curable resin and plasticizer.
従来は、様々なアクリル樹脂を使用しても可塑剤がブリードアウトせず、硬化収縮率を低くすると共に低粘度化することが困難であった。 Conventionally, even when various acrylic resins are used, the plasticizer does not bleed out, and it has been difficult to lower the cure shrinkage and lower the viscosity.
本発明者らは、上記目的を達成するべく鋭意検討した結果、ブリードアウトせずに低い硬化収縮率を発現する光硬化性組成物に関する発明を完成するに至った。 As a result of intensive studies to achieve the above object, the present inventors have completed an invention relating to a photocurable composition that exhibits a low curing shrinkage rate without bleeding out.

The maximum strength at that time is defined as “peeling adhesive strength (N / 20 mm)”. The peel strength is preferably 0.1 to 1.0 N / 20 mm. If the peel strength is 0.1 N / 20 mm or more, the protective film (cured product) is stably adhered to the adherend, and if the peel strength is 1.0 N / 20 mm or less, it is peeled off after polishing and cutting. be able to.
(B)成分および(C)成分を含まない比較例1〜5は、実施例1〜10と比較して、ブリードアウトが7日より短く、硬化物からの分離が早い。本発明を仮固定用途に使用した時に、数日にわたって作業を行う際には長期間安定した硬化物であることが必要とされる。また、(A)成分100質量部に対して(B)成分および(C)成分の合計が100質量部に満たない比較例6は硬化収縮率が3.0%より高く、被着体に対して応力がかかる。そのため、ウェハ等を仮固定する際には硬化収縮によりウェハ等が歪むことが想定される。 Compared with Examples 1-10, the comparative examples 1-5 which do not contain (B) component and (C) component have a bleed-out shorter than 7 days, and the isolation | separation from hardened | cured material is quick. When the present invention is used for temporary fixing, a cured product that is stable for a long period of time is required when working over several days. Moreover, the comparative example 6 in which the sum total of (B) component and (C) component is less than 100 mass parts with respect to 100 mass parts of (A) component has a cure shrinkage rate higher than 3.0%, and with respect to a to-be-adhered body. Stress. Therefore, when temporarily fixing a wafer or the like, it is assumed that the wafer or the like is distorted due to curing shrinkage.
本発明は、硬化収縮率が低くいが、可塑剤がブリードアウトしないため硬化物表面にべたつきが無く取扱性が良好である。当該硬化収縮率から被着体に対して応力を与えにくいため、シリコーンウェハ、サファイアガラス、セラミックス材料、光学用ガラス、水晶、磁性材料などを仮固定するのに最適である。仮固定後に被着体を研磨や切削することができ、仮固定工程がある作業に於いて汎用的に使用することができる。 Although the present invention has a low cure shrinkage ratio, the plasticizer does not bleed out, so the cured product surface is not sticky and has good handleability. Since it is difficult to apply stress to the adherend due to the curing shrinkage rate, it is optimal for temporarily fixing a silicone wafer, sapphire glass, ceramic material, optical glass, crystal, magnetic material, and the like. The adherend can be ground or cut after temporary fixing, and can be used for general purposes in operations having a temporary fixing step.
