US 2026/0262340 A1 · LED CHIP ELECTRODE

Abstract

The present invention discloses an LED chip electrode, relating to the technical field of semiconductor photoelectric devices. The LED chip of the present invention includes a chip body, electrode pads disposed on the periphery of the chip body, and finger gold wire electrodes disposed on a surface of the chip body. Four or more electrode pads are provided, and are symmetrically and equally spaced apart along the periphery of the chip body. The finger gold wire electrodes are equally spaced apart, and a spacing between two adjacent ones of the finger gold wire electrodes is determined according to the following formula: Ls=n*sqrt(Rc/Rs), where Ls is the spacing between the finger gold wire electrodes, n is an electrode pad factor, Rc is a contact resistance between the finger gold wire electrodes and the chip body, and Rs is a sheet resistance of the chip body.
