We manufacture an antifuse OTP (One-time programmable) cell for analog trimming which will be used in power management ICs. For the antifuse cell using dual program voltage of VPP (=7V) and VNN (=-5V), the thin gate oxide is broken down by applying a voltage higher than the hard break-down voltage to the terminals of the antifuse. The area of the manufactured antifuse OTP cell using 0.18§ BCD process is 48.01§2 and is about 44.6 percent of that of an eFuse cell. The post-program resistances of the antifuse are good with the values under several kilo ohms when we measure twenty test patterns.
