In a non-volatile semiconductor memory having a peripheral circuit zone and a memory zone including plural memory cells each having a floating gate and a control gate, an interlayer insulator is formed over the control gate of the memory cells and a gate electrode in the peripheral circuit zone. A groove is formed in the interlayer insulator film to longitudinally extend along a word line which constitutes the control gate for a plurality of memory cells arranged in one line. This groove penetrates through the interlayer insulator film to reach the word line over the whole length of the word line. A conducting material is deposited on the interlayer insulator film to fill up the groove so that a plate-shaped contact is formed in the groove. The conducting material is patterned to form an overlying interconnection extending on the interlayer insulator film along the word line.
