Abstract
A method for manufacturing a semiconductor device includes the following steps. A semiconductor substrate is prepared which has a first main surface and a second main surface opposite to each other. The semiconductor substrate is fixed on an adhesive tape at the first main surface. The semiconductor substrate fixed on the adhesive tape is placed in an accommodating chamber. While maintaining a temperature of the adhesive tape at 100° C. or more, a gas is exhausted from the accommodating chamber. After the step of exhausting the gas from the accommodating chamber, a temperature of the semiconductor substrate is reduced. After the step of reducing the temperature of the semiconductor substrate, an electrode is formed on a second main surface of the semiconductor substrate. In this way, there can be provided a method for manufacturing a semiconductor device so as to achieve reduced contact resistance between a semiconductor substrate and an electrode.
