Adhesive film and semiconductor device |
| abstract |
PROBLEM TO BE SOLVED: To provide a heat resistant adhesive film useful for a DAF: die attachment film capable of realizing a highly durable semiconductor package. [MEANS FOR SOLVING PROBLEMS] A polyimide film (layer b) having a pyromellitic acid residue as an aromatic tetracarboxylic acid residue and a diamine residue having a benzoxazole skeleton as an aromatic diamine residue is logarithmic as an adhesive. It is an adhesive film in which a polyamideimide resin layer (a layer) having a viscosity of 0.1 dl / g or more and copolymerized with a dimer acid is laminated, and has a linear expansion coefficient of −5 to 10 ppm / ° C. in the surface direction of the polyimide film. It is preferable that [Selection figure] None |
