摘要:
An ESD protection apparatus comprises a substrate, a low voltage p-type well and a low voltage n-type well formed on the substrate. The ESD protection device further comprises a first P+ region formed on the low voltage p-type well and a second P+ region formed on the low voltage n-type well. The first P+ region and the second P+ region are separated by a first isolation region. The breakdown voltage of the ESD protection apparatus is tunable by adjusting the length of the first isolation region.
