    摘要: A high-density deep trench capacitor array with a plurality of leakage sensors and switch devices. Each capacitor array further comprises a plurality of sub-arrays, wherein the leakage in each sub-array is independently controlled by a sensor and switch unit. The leakage sensor comprises a current mirror, a transimpedance amplifier, a voltage comparator, and a timer. If excessive leakage current is detected, the switch unit will automatically disconnect the leaky capacitor module to reduce stand-by power and improve yield. An optional solid-state resistor can be formed on top of the deep trench capacitor array to increase the temperature and speed up the leakage screening process.
