Abstract
Abstract A plurality of electrodes are formed on one surface of a semiconductor integrated circuit chip. A plurality of leads are arranged around the chip. Each of the electrodes and one end of each of the leads are connected. The electrodes and the chip are sandwiched between two films. One of the films is in direct contact with the one surface of the chip. The other film is in direct contact with the other surface of the chip.
