REPAIR CIRCUIT HAVING ENTY FUSE FOR SURPLUS CELL PROGRAM AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A repair circuit having anti fuse for a surplus cell capable of improving yield and reliance of a semiconductor device by using a threshold voltage of an insulator is provided. CONSTITUTION: The repair circuit having en anti fuse for a surplus cell program comprising: a half power supply(100) for performing a switching operation to supply a half supply power; a programming voltage supply section(40) for supplying a programming voltage to program a bad cell; a ground voltage supply section(30) for applying a ground voltage in response to an address signal; an anti fuse(20) charged by the half supply power from the half power supply(100) at a normal operation, and destroying and programming an insulating film according to a difference between the voltage from the programming voltage supply section(40) and the voltage from the ground voltage supply section(30); and an output section(50) for generating an output signal according to a voltage applied to from a node to which the half power supply(100), the programming voltage supply section(40), and the anti fuse(20) are common connected.
