Abstract
A semiconductor device is formed by sealing, with a resin, a semiconductor chip (CP) having an oscillation circuit utilizing a reference resistor. The oscillation circuit generates a reference current by utilizing the reference resistor, a voltage is generated in accordance with this reference current and an oscillation frequency of the oscillation unit, and the oscillation unit oscillates at a frequency in accordance with the generated voltage. The reference resistor is formed of a plurality of resistors, which extend in a first (Y) direction orthogonal to a first side, inside a first region (RG, RG, RG, and RG) surrounded by the first side (S, S, S, and S) of a main surface of the semiconductor chip (CP), a first line (, and) connecting between one end of the first side and the center (CT) of the main surface of the semiconductor chip, and a second line (, and) connecting between the other end of the first side and the center of the main surface of the semiconductor chip.
