Abstract
In an integrated circuit supporting complementary metal oxide semiconductor (CMOS) integrated circuits, latch-up immunity is supported by surrounding a hot n-well with an n-well strap spaced from the hot n-well by a specified distance in accordance with design rules. The n-well strap is positioned between the hot n-well and other n-well or n-type diffusion structures.
