As we all know, the LED chip industry has seen significant price drops in the past due to the influx of new large-scale investments. Although the current decline has stabilized and even shown a slight rebound, the competition for market dominance is expected to lead to another round of price fluctuations in the future, potentially resulting in irrational competition. Moreover, since the quality of LED chips greatly affects the performance of downstream packaging or end products, customers have high expectations regarding the consistency, stability, light decay, and luminous efficiency of these chips.
Currently, Japan and the United States hold a monopoly over high-efficiency chip technology and dominate the high-end market. In contrast, domestic LED chip technology faces several challenges, including low light output power, low luminous efficiency, and low production efficiency. The root cause of these issues lies in outdated chip structure design and manufacturing techniques. As a result, China lags behind global leaders in this field, which hinders the development of its LED lighting and high-end display industries.
Huacan Optoelectronics Co., Ltd. (hereinafter referred to as "Huacan Optoelectronics") is a leading supplier of LED chips in China and a high-tech enterprise in the fields of "new materials and new energy." For many years, the company has been dedicated to the research, development, production, and sales of full-color, high-quality LED epitaxial materials and chips.
Recently, Huacan Optoelectronics launched a new product: the "High-efficiency LED Chip," which was successfully introduced to the market. This technology has obtained relevant invention patents and represents a breakthrough in core technologies, innovative structural design, and advanced manufacturing processes. It focuses on four key areas: luminous power, internal quantum efficiency, external quantum efficiency, and production efficiency. These high-efficiency chips are playing a crucial role in driving industry development.
1. **GaN-LED Chip with Unique Structural Design**: To address the issue of poor heat dissipation in GaN-based LED chips, Huacan Optoelectronics developed a high-efficiency chip with a direct patch package design, along with its preparation technology.
2. **Super-Lattice Insertion Layer Technology**: The invention features an AlxGa1-xN/GaN superlattice periodic structure intercalation layer and its corresponding preparation technique. This reduces lattice mismatch, enhances crystal quality, minimizes dislocations and non-radiative recombination centers, and ultimately improves the quantum efficiency of the chip.
3. **Interface Modification Integrated Preparation Technology**: By employing cross-section modification and integrated preparation technology, the company reduced photon interface loss and improved external quantum efficiency. Optimized patterned substrates and DBR reflective layers significantly enhance the chip's light-emitting efficiency.
4. **AlN Buffer Layer Technology**: Huacan Optoelectronics developed PVD deposition technology for the AlN buffer layer. A single-layer AlN film was deposited on sapphire substrates, reducing interface mismatch and improving both the quality of the crystal film and production efficiency.
Through years of effort, Huacan Optoelectronics has achieved four major technological breakthroughs, successfully developing "high-efficiency LED chips" and overcoming previous bottlenecks. This has effectively enhanced the international competitiveness of China’s high-efficiency LED chips.
Given the product's unique innovation and strong market potential, Huacan Optoelectronics decided to enter it for the 2017 Innovation Golden Product Award “Innovative Product of the Year.â€
