It consists of an adhesive tape-like adhesive film and a release film attached to the pressure-sensitive adhesive surface. The release film is used to prevent the pressure-sensitive adhesive layer of the adhesive film from being contaminated during distribution and storage.

。Conventionally, as the release film, a plastic film made of polyester or the like is treated with a silicone release agent or the like and has a coated film on the surface thereof.
しかしながら、剥離剤の塗布皮膜からなる剥離層はその
本来の性質に基づき被処理フィルムより脱落しやすい。However, due to its inherent properties, the release layer made of a film coated with a release agent is more likely to fall off than the film to be processed.

清澄条件が要求される半導体チップの製造過程において
は容認しえない問題点となっていた。Therefore, over time, the release layer gradually falls off from the processed film and is transferred to the pressure-sensitive adhesive surface, which contaminates the wafer when it is attached to a semiconductor wafer, requiring high clarification conditions. This has become an unacceptable problem in the manufacturing process of semiconductor chips.

易である。Function: By using a release film having a release layer made of low-density polyethylene or polymethylpentene, it is possible to effectively prevent the release layer from being transferred to the pressure-sensitive adhesive layer. Contamination of the semiconductor wafer by transferred materials can be avoided. Furthermore, a decrease in the adhesive strength of the pressure-sensitive adhesive layer due to the transfer is also avoided. Furthermore, it is also easy to peel off the release film from the adhesive film.

さが5μm未満では均一厚の剥離フィルムが得にくい。Examples of Constituent Elements of the Invention The release film used in the present invention has a release layer made of low density polyethylene or polymethylpentene. Therefore, the release film may be a single layer made of low density polyethylene, polymethylpentene or a mixture thereof, or a multilayer film having a release layer made of the resin on at least the surface. When constructed as a single layer, its thickness is 40 μm or more, especially 40 μm.
~100 μm is suitable. If the thickness is less than 40 μm, the film may break when peeled off due to insufficient strength. When constructed as a multilayered product, the thickness of the release layer made of the resin is preferably 5 μm or more, particularly 5 to 100 μm. If the thickness is less than 5 μm, it is difficult to obtain a release film with a uniform thickness.

の点より適宜に決定される。In addition, in the case of constructing a multilayer product, there is no particular limitation on the composition of the layers other than the release layer, and it is appropriately determined from the point of view of physical properties such as film strength.

タイプのものが好ましく用いられる。Therefore, adhesive films generally consist of a support substrate made of thin plastic material and a pressure-sensitive adhesive layer disposed thereon. That is, a supporting base material of 20 to 500 μm in thickness, which is typically a film made of polyolefins such as polyethylene, polypropylene, or polyesters such as polyethylene terephthalate, is coated with acrylic, rubber, styrene-isobutylene, etc. Generally, a typical known pressure-sensitive adhesive layer is provided with a thickness of 1 to 500 μm. As the pressure-sensitive adhesive, it is preferable to use a type that does not leave any components on the adherend when it is peeled off, for example by adjusting the cohesive force or removing separated components.

It is possible to effectively prevent the components forming the wafer from being transferred, thereby effectively preventing contamination of the semiconductor wafer.
