PROBLEM TO BE SOLVED: To suppress an increase in the total area of a substrate in a semiconductor integrated circuit in which an analog circuit and a digital circuit are mixed.SOLUTION: A semiconductor integrated circuit 1 comprises: an analog circuit 13; and a digital circuit 14 that converts an analog output signal from the analog circuit 13 into a digital signal. A part 19 of the analog circuit is formed on a first semiconductor substrate 51, and the other part 37 of the analog circuit and the digital circuit 14 are formed on a second semiconductor substrate 53. The first semiconductor substrate 51 and the second semiconductor substrate 53 are connected by a substrate connection portion 55. The substrate connection portion 55 transmits the analog signal generated by the part 19 of the analog circuit to the second semiconductor substrate 53. |
