摘要:
A plastic laminated metallic foil is prepared by laminating a first layer of a polymer selected from the group consisting of ethylene-unsaturated carboxylic acid copolymers, ethylene-unsaturated carboxylic acid ester copolymers, ethylene-unsaturated carboxylic acid-unsaturated carboxylic acid-ester ternary copolymers, ionomers containing these copolymers as the base, and graft copolymers of polyethylene and unsaturated carboxylic acids on at least one surface of a metallic foil, and further laminating a second layer of a polymer selected from the group consisting of polyethylene, ethylene-vinyl acetate copolymers, ethylene-unsaturated carboxylic acid ester copolymers, and graft copolymers of polyethylene and unsaturated carboxylic acid esters onto the first polymer layer of the metallic foil.

This invention relates to an organic polymer having, as the main repeating unit, the compound represented by the general formula: ##STR1## (wherein, m and n respectively show the molar fraction of quinonediimine structure unit and phenylenediamine structure unit in the repeating unit, and 0
摘要:
A dicing-die bonding film comprising an ultraviolet-transmitting substrate having provided thereon an ultraviolet-curable pressure-sensitive adhesive layer and an adhesive layer in this order, the pressure-sensitive adhesive layer having been partly ultraviolet-cured to have cured parts and uncured parts. The film has a well-balanced combination of a holding power for supporting a semiconductor wafer during dicing and release properties for enabling cut chips to be easily released together with the adhesive layer so that even large-sized chips as larger than 10 mm.times.10 mm can easily be picked up.
