Abstract
It is prevented that when a predetermined number of semiconductor chips having transistors are manufactured from one semiconductor wafer, manufacturing cost of a semiconductor device is increased due to excess semiconductor chips manufactured from the semiconductor wafer. A first bipolar transistor including a first emitter region having a first area is formed in a first chip formation region in an exposure region that can be exposed by one exposure step, and a second bipolar transistor including a second emitter region having a second area different from the first area is formed in a second chip formation region in the exposure region.
