Latchup failure induced by electrostatic discharge (ESD) protection circuits occurred anomalously in a high-voltage IC product. Latchup issues existed at only three output pins, two of which belonged to the top and the other to the side. The layouts of top and bottom output pins are identical, and side output pins have another identical layouts. In our(More)
ESD/latchup are often two contradicting variables during IC reliability development. Trade-off between the two must be properly adjusted to realize ESD/latchup robustness of IC products. A case study on SERIAL Input/Output (I/ O) IC's is reported here to reveal this ESD/latchup optimization issue. SERIAL I/O IC features a special clamping property to wake(More)
