ABSTRACT:
A semiconductor device includes: a semiconductor substrate including an active element formation face on which an active element is formed, and a rear face that is on a side opposite to the active element formation face; a penetration electrode penetrating the semiconductor substrate; an element electrode formed on or above the active element formation face; detection electrodes formed on or above the rear face, electrically connected to the element electrode via the penetration electrode, and detecting a remaining amount of the ink by being wet in the ink; a storage circuit storing the remaining amount of ink; an antenna formed on either one of the active element formation face and the rear face, transmitting and receiving information; and a control circuit controlling the detection electrodes, the antenna, and the storage circuit.
