[Text|High-tech LED reporter Yue Mengdi] Blu-ray chip has always been the main battlefield of the chip market. In recent years, the production capacity of Blu-ray chips in China has entered a stage of rapid release. Domestic chip companies have gradually introduced technology and increased R&D investment in recent years, gradually changing the acceptance of mainland packaging chips in the past packaging factories, and the market share has also steadily increased.
Nantong Tongfang Semiconductor Co., Ltd. (hereinafter referred to as "Tongfang Semiconductor") has been focusing on the research and development of LED epitaxial wafers and chips. This year, it will once again participate in the 2014 Gaogong Golden Globe Awards with Blu-ray chips.
Tongfang Semiconductor Dr. Wu Donghai told the "High-tech LED" reporter that this year's Tongfang Semiconductor competed for the Golden Globe Award for gallium nitride (GaN) high-brightness blue LED chips, the biggest advantage is low voltage and high light efficiency.
According to the reporter's understanding, the low voltage of the LED chip can meet the current high current drive demand, and has a high cost performance. "We have passed some R&D work to make the chip at a current density of 35A/cm2, and the voltage can be less than 3.2V." Dr. Wu Donghai said.
Tongfang Semiconductor has a comparative advantage in the blue chip. Under the injection current density of 35A/cm2, the luminous efficiency of gallium nitride (GaN) high-brightness blue LED chip can be more than 150lm/W, which is more than last year's participation in the high-tech LED Golden Globe Award. The LED chip has increased by 10%.
"As far as the chip is concerned, the most important thing is its level of extension technology." Dr. Wu Donghai said. Epitaxy, which is the process of obtaining the device structure, is the most technologically advanced process step that directly determines the internal quantum efficiency of the LED. Tongfang Semiconductor adopts the newly developed high-brightness, low-voltage GaN-based LED epitaxial layer structure to ensure low-voltage characteristics under high current density injection.
How to improve the light extraction efficiency and get a better heat dissipation solution is the main purpose of chip design. Tongfang Semiconductor's gallium nitride (GaN) high-brightness blue LED chip is equipped with advanced DBR mirrors, Sputter ITO, current blocking layer and other chip preparation technology to improve the luminous efficiency of LED chips. At the same time, Tongfang Semiconductor's high-brightness blue LED chip has good antistatic capability, and the ESD 2000V yield is greater than 97%, which ensures that the product can be widely used in high-end general illumination and large-size TV backlight applications, and also breaks the field. The situation in which products are monopolized by imported products.
It is understood that the gallium nitride (GaN) high-brightness blue LED chip can achieve high efficiency of internal quantum efficiency and light extraction technology combined with maximum power consumption, with its good quality, has been successively in mainland China, Taiwan, South Korea and other mainstream packaging plants are used.
