Claim 29:
30. An integrated circuit, comprising:
a thin film that has a band gap of 2.2 eV or more and in which a crystal includes a composite defect of an impurity atom and a vacancy;
a microwave irradiation system configured to irradiate the thin film with a microwave;
an excitation unit configured to excite the thin film; and
a detector configured to detect at least either one of an intensity of light outputted from the thin film when transitioning from an excited state to a ground state and a change in conductivity of the thin film,
wherein the thin film is formed by chemical vapor deposition using a gas mixture containing approximately 10% to 15% of a noble gas.
