Light emitting diode chip with integrated diode for electrostatic discharge protection

Light emitting diode chip with integrated diode for electrostatic discharge protection

A relatively small ESD protection diode is formed on the same chip as a light emitting diode. In one embodiment, the ESD diode is a mesa-type diode isolated from the light emitting diode by a trench. To reduce the series resistance of the ESD diode, the PN junction and metal contact to the semicondu...

description A relatively small ESD protection diode is formed on the same chip as a light emitting diode. In one embodiment, the ESD diode is a mesa-type diode isolated from the light emitting diode by a trench. To reduce the series resistance of the ESD diode, the PN junction and metal contact to the semiconductor material is made long and expands virtually the width of the chip. Various configurations of the PN junction and the N and P metal contacts for the ESD diode are described for increasing the breakdown voltage and for improved testing.
