Abstract

The invention provides a semiconductor epitaxial structure, a manufacturing method thereof and an LED chip, and the method comprises the steps of sequentially stacking an N-type semiconductor layer, a gate elimination layer, an active layer and a P-type semiconductor layer on the surface of a substrate. Redundant electrons are released through the design of the epitaxial structure, the electron concentration is effectively improved, the electron tunneling probability is increased, the working voltage of an LED is reduced while the crystal quality is improved, and the anti-static capability of the LED is improved.

Description

technical field [0001] The invention relates to the field of light-emitting diodes, in particular to a semiconductor epitaxial structure, a manufacturing method thereof, and an LED chip. Background technique [0002] A light-emitting diode (English: Light Emitting Diode, referred to as: LED) is a semiconductor electronic component that can emit light. LED has the advantages of high efficiency, long life, small size, low power consumption, etc., and can be used in indoor and outdoor white light lighting, screen display, backlight and other fields. In the development of the LED industry, gallium nitride (GaN)-based materials are typical representatives of Group V-III compound semiconductors, and improving the photoelectric performance of GaN-based LEDs has become the key to the semiconductor lighting industry. [0003] Epitaxial wafers are the primary products in the LED manufacturing process. The existing GaN-based LED epitaxial wafer includes a substrate, an N-type semicon...
