Abstract - In this work, various layout options for ESD diodes’ PN junction geometry and metal routing are
investigated. The current compression point (ICP) is introduced to define the maximum current handling
capability of ESD protection devices. The figures-of-merit ICP/C and RON*C are used to compare the
performance of the structures investigated herein.
