A nondendrimeric hyperbranched polyester andor polyesteramide which comprise alkenyl-substituted succinic acid units as demulsifiers for splitting oil-water emulsions, especially crude oil emulsions. Based on vehicle position, data about possible routes which may be taken is collected from at least three sources. Subsequently, the semiconductor chips and the matrix substrate are bonded to each other temporarily by thermocompression bonding, while heating the chips directly by the first heating stage.
