BONDING FILM, TAPE FOR WAFER PROCESSING, METHOD FOR PRODUCING BONDED BODY, AND BONDED BODY AND PASTED BODY
A bonding film for bonding a semiconductor element and a substrate. The bonding film has an electroconductive bonding layer formed by molding an electroconductive paste including metal fine particles (P) into a film form, and a tack layer having tackiness and laminated on the electroconductive bonding layer. The tack layer includes 0.1% to 1.0% by mass of metal fine particles (M) with respect to the metal fine particles (P) in the electroconductive bonding layer, and the metal fine particles (M) have a melting point of 250° C. or lower.

FIXED-ARRAY ANISOTROPIC CONDUCTIVE FILM USING CONDUCTIVE PARTICLES WITH BLOCK COPOLYMER COATING
Structures and manufacturing processes of an ACF array and more particularly a non-random particles are transferred to the array of microcavities of predetermined configuration, shape and dimension. The manufacturing process includes fluidic filling of conductive particles surface-treated with a block copolymer composition onto a substrate or carrier web comprising a predetermined array of microcavities. The thus prepared filled conductive microcavity array is then over-coated or laminated with an adhesive film.
