Abstract -- The diode operated in forward-biased condition has
been widely used as an effective on-chip ESD protection device at
8 j* O) f6 q/ m- ~! gGHz RF and high-speed I/O pads due to the small parasitic
loading effect and high ESD robustness in CMOS integrated
circuits (ICs). This work presents new ESD protection diodes
realized in the octagon, waffle-hollow, and octagon-hollow layout
styles to improve the efficiency of ESD current distribution and
to reduce the parasitic capacitance. The new ESD protection

不知道这种形式的ＩＯ有没有经过测试，实际的效果和预想的有多少的差别，thanks!
