Abstract
A semiconductor integrated circuit device including a semiconductor substrate having a first surface on which a circuit block is formed, and a second surface opposite to the first surface; a mounting board on which the semiconductor substrate is mounted; an electrically conductive pattern formed over a region of the mounting substrate, which overlaps a portion to be protected of the circuit block; and a detection circuit configured to detect that the electrically conductive pattern has been altered is provided. The semiconductor substrate is mounted on the mounting board such that the second surface of the semiconductor substrate faces the mounting board.
