A method of forming an electrostatic discharging (ESD) device includes forming a first and a second semiconductor fin over a substrate and adjacent to each other; epitaxially growing a semiconductor material on the first and the second semiconductor fins, wherein a first portion of the semiconductor material grown from the first semiconductor fin joins a second portion of the semiconductor material grown from the second semiconductor fin; and implanting a first end and a second end of the semiconductor material and first end portions of the first and the second semiconductor fins to form a first and a second implant region, respectively. A P-N junction is formed between the first end and the second end of the semiconductor material. The P-N junction is a junction of an ESD diode, or a junction in an NPN or a PNP BJT.
