Abstract
Some embodiments are related to a mesh capacitor, which improves the SER FIT rate. In an embodiment, the capacitor is connected between an input and an output of a latch in a flip-flop, making the flip-flop harder to flip due to radiation (e.g., from neutrons and/or alpha particles). In some embodiments, the capacitor is built directly vertically on top of the flip-flop, saving chip layout areas.
