Recently, China Resources Shanghua Technology Co., Ltd. (hereinafter referred to as "China Resources Shanghua"), a subsidiary of China Resources Microelectronics Co., Ltd. ("China Resources Microelectronics"), announced that the company has successfully developed the third-generation 0.18-micron BCD process platform. The new-generation BCD process platform improves the reliability of the device and reduces the process cost while reducing the on-resistance. It can cover a wide operating voltage range of 7V-40V, providing a competitive process solution for the design of power management ICs. . Based on a large amount of simulation and tape-out data, the third-generation 0.18-micron BCD process of CR Shanghua optimizes the structure of high-voltage devices and achieves the industry-leading comprehensive performance. Among them, the breakdown voltage of 30V nLDMOS reaches 50V, and the on-resistance is only 15 mohm*mm^2. Compared with the second-generation 0.18-micron BCD process, the quality factor (Ron*Qg) index is optimized by 25%. The new-generation BCD process platform provides a wide range of parasitic devices such as BJT, Poly resistor, Zener, and SBD, as well as ESD protection solutions for different operating voltages. At present, customers in mobile phones, security monitoring, consumer electronics and other fields have introduced products on this platform, and the device performance has been unanimously recognized by many customers at home and abroad. As a leading analog wafer foundry in China, CR Shanghua has been working on the BCD process platform for many years and has rich experience in mass production, ranging from 6-inch production lines to 8-inch production lines, extending from 1 μm to 0.18 μm, and can be used on various nodes. Meet customers' all-round needs for power management chip design. Shao Jun, Deputy General Manager of Marketing and Sales of China Resources Shanghai, said: "We expect the third-generation 0.18-micron BCD process platform to provide customers with more cost-effective solutions. In the future, China Resources Shanghai will continue to improve and improve the competition of BCD process platforms. power to meet the various needs of customers on power management chips.â€
