April 23, 2015 by Jeff Shepard

Hua Hong Semiconductor Limited has achieved mass production of its new-generation ultra-high voltage 0.5um 700V BCD series process platform with over 98% yield, reached the world-class production level. This process platform mainly focuses on the applications of green energy such as ac-dc converters and LED lighting, featuring industry-leading advantages, such as low on-resistance, high reliability, low cost and short manufacturing cycle time, which is capable of providing the customers with highly competitive single-chip solutions. Currently, multiple customers have performed mass production through this platform, with all the indicators meeting or exceeding their requirements.

In the global trend of energy saving, LED green lighting has entered a period of rapid expansion. According to the statistics of relevant agencies, the LED lighting IC market is expected to expand from US$700 million in 2013 to US$1.5 billion in 2020 with a compound annual growth rate of 11.8%. In particular, currently the market penetration of LED lighting in China is only 20% to 30%, indicating a huge market size in the future.

Hua Hong Semiconductor's new-generation 0.5um 700V BCD process is an upgraded process based on the first-generation 1um 700V BCD process developed in 2013. While maintaining the original cost advantage of at least 12 pieces per 1P1M (1 poly layer and 1 metal layer), the new process further integrates 7.5V CMOS, 20V/40V medium-voltage LDMOS and 200V/300V/400V/500V/600V/650V/700V high-voltage power LDMOS for a broader scope of ultra-high voltage options to meet the needs of different voltage applications.

This solution can provide difference-oriented Junction Field-Effect Transistor (JFET) and high-voltage resistance devices for start-up circuits as well as a lot of options include bipolar transistors (VPNP/LNPN), precision resistors and capacitors and Zener diodes with low temperature coefficients, greatly facilitating the customers to use it in design and development. Meanwhile, this process solution optimizes the design rules for high-voltage device modules, especially for specific on-resistance of ultra-high voltage devices, of which the core specific on-resistance of 700V DMOS device has reached the international advanced level.

With experienced IP design and test teams, Hua Hong Semiconductor is able to provide the customers with a variety of high-voltage power module IPs which can be fully customized according to the customers' requirements, thereby reducing the design difficulty and cost for the customers and shortening the product development time so as to help them quickly capture market opportunities.

"Hua Hong Semiconductor's ultra-high voltage 700V BCD technology caters for the trend of energy saving. Supported by this process platform, the high-voltage, low-current LED lighting drivers have a very broad market prospect", said Dr. Kong Weiran, Executive Vice President of Hua Hong Semiconductor, "We intend to continue to further enhance our advanced and differentiated process technology portfolio applied to LED lighting to manufacture high-performance, cost-effective LED driver ICs. In the future, we will expand our advanced power management platform to offer a comprehensive suite of cost-effective solutions for customers."
