A fin field-effect transistor (FinFET) is a promising candidate for the platform of a Si quantum computer. The noise properties of commercial FinFETs are investigated experimentally at a temperature of less than 10 K. The drain current shows a Coulomb oscillation, which indicates that the FinFET channel becomes a single quantum dot. The noise of the drain current is analyzed, and the basic properties of commercial FinFETs in the low-temperature region are discussed.
