近年、半導体業界ではスマートフォンなどのモバイル機器の小型化・高機能化・低コスト化に対応するため、チップ基板となるシリコンウエハの薄化や、製造効率向上を目的とした大型CCL基板やBT基板等への転換が進められている。しかし、薄基板や大型CCL基板・BT基板では反りが顕著になるため、封止材に大きな負荷がかかり、接着面と剥離が生じやすくなっており、封止材の接着力がまずます重要となってきている。これまでに、封止材の接着力向上のため、種々検討が進められてきたが、更なる高接着の封止材が求められている(特許文献1)。 In recent years, in the semiconductor industry, in order to respond to the miniaturization, high functionality, and cost reduction of mobile devices such as smartphones, silicon wafers used as chip substrates have become thinner, and large CCL substrates and BT substrates aimed at improving manufacturing efficiency. The conversion to such as is in progress. However, since warpage becomes remarkable on thin substrates, large CCL substrates, and BT substrates, a large load is applied to the encapsulant, and it is easy for the adhesive surface to peel off, so the adhesive strength of the encapsulant is of the utmost importance. It has become to. Various studies have been carried out to improve the adhesive strength of the sealing material, but there is a demand for a sealing material having higher adhesiveness (Patent Document 1).
また、製造効率を上げるため、CCLやBT基板は角基板を用いることが多いが、これを封止する際、液状封止材では基板の内側と外側でムラが生じやすくなるため、これを容易に均一封止できるフィルムタイプが望まれていた。 Further, in order to improve the manufacturing efficiency, a square substrate is often used for the CCL or BT substrate, but when sealing the CCL or BT substrate, the liquid encapsulant tends to cause unevenness on the inside and outside of the substrate, which is easy. A film type that can be uniformly sealed has been desired.
そこで、歪曲時も剥離の生じづらい高接着樹脂組成物、及びこれを用いた良好なウエハ保護性能を有するウエハモールド材の開発、及び、そのフィルム化が望まれていた。 Therefore, it has been desired to develop a highly adhesive resin composition that does not easily peel off even when distorted, and a wafer mold material having good wafer protection performance using the composition, and to form a film thereof.

Each resin composition was applied onto the base film using a die coater as the film coater and E7304 (trade name, polyester manufactured by Toyobo Co., Ltd., thickness 75 μm, peeling force 200 mN / 50 mm) as the base film. .. Then, the solvent was completely evaporated by putting it in an oven set at 100 ° C. for 20 minutes to form a resin film having a film thickness of 100 μm on the base film.
