摘要:
An adhesive film for a semiconductor chip with a through electrode, which is used for stacking multiple semiconductor chips each with a through electrode on a semiconductor wafer, which can favorably connect the through electrodes while suppressing formation of voids, and which can reduce the length of burrs protruding around the semiconductor chips. An adhesive film for a semiconductor chip with a through electrode, to be used for stacking multiple semiconductor chips each with a through electrode on a semiconductor wafer, the adhesive film having a minimum melt viscosity of 50 to 2500 Pa·s and a thixotropic index at 140° C. of 8 or lower.
