Title (EN) MULTILAYERED ADHESIVE FILM
(FR) FILM ADHÉSIF MULTICOUCHE
Abstract: front page image
(EN)Multilayered adhesive films that include a support layer, a first adhesive layer on or over the support layer and a second adhesive layer abutting the first adhesive layer, are provided. Of the abutting surfaces of the first and second adhesive layers, the first adhesive layer has a first profile and/or the second adhesive layer has a second profile. The first and/or second profiles are each independently selected such that the peel strength between the first and second adhesive layers is reduced relative to the comparative peel strength of a comparative multilayered adhesive film that is free of the first and second profiles. The multilayered adhesive films of the present invention may be used as dicing die attach films. Also provided is an assembly that includes a separate article (e.g., a silicon wafer) adhered to the multilayered adhesive film of the present invention.
(FR)L'invention concerne des films adhésifs multicouches qui comprennent une couche support, une première couche adhésive sur ou au-dessus de la couche support et une seconde couche adhésive adjacente à la première couche adhésive. Parmi les surfaces adjacentes de la première et de la seconde couche adhésive, la première couche adhésive a un premier profil et/ou la seconde couche adhésive a un second profil. Le premier et/ou le second profil sont chacun choisis indépendamment de manière à ce que la résistance au pelage entre la première et la seconde couche adhésive soit réduite par rapport à la résistance au pelage comparative d'un film adhésif multicouche comparatif qui ne comprend pas le premier et le second profil. Les films adhésifs multicouches de la présente invention peuvent être utilisés en tant que films de fixation pour filière de découpage en dés. L'invention concerne également un ensemble qui comprend un article séparé (p. ex. une plaque de silicium) adhéré au film adhésif multicouche de la présente invention.
