Abstract
Diodes and bipolar junction transistors (BJTs) are formed in IC devices that include fin field-effect transistors (FinFETs) by utilizing various process steps in the FinFET formation process. The diode or BJT includes an isolated fin area and fin array area having n-wells having different depths and a p-well in a portion of the fin array area that surrounds the n-well in the isolated fin area. The n-wells and p-well for the diodes and BJTs are implanted together with the FinFET n-wells and p-wells.
