Abstract
A semiconductor device is provided with a polyimide film 21 between the encapsulating synthetic resin 16 and the passivating film 20. If a material having a high hardness (E-modulus.gtoreq.1.0.multidot.10.sup.10 Pa) is selected as the polyimide, the number of defects caused by variations in temperature is reduced.
