MagnaChip Offers 0.35 micron 700V Ultra High Voltage Process Technology with Process Simplification
Millions of home appliances use AC power, but there also are many millions of high-performance and cost-sensitive products in high-growth markets that use AC-DC chargers, AC-DC converter ICs and LED driver ICs. The demanding technical specifications of these products require substantial improvements in the price-performance of the UHV process technology used in the manufacture of AC-DC converter ICs or LED driver ICs, particularly for the industrial lighting market.
MagnaChip provides various types of UHV technology to meet the demanding needs of customer requirements for improved UHV processes. HP35ULA700, the newly developed UHV process, eliminates four photolithography steps through process simplification -- making it possible to reduce manufacturing cost and accelerate a company's time to market. Among the devices offered in HP35ULA700 are 700V low Ron nLDMOS, 400V/500V nLDMOS, 700V JFET, 30V high voltage device, 5.5V CMOS, BJT, 700V resistor, fully isolated 30V diode, BP cap, and MIM and fuse. All of these devices enable the integrated solution of AC-DC converter ICs and LED driver ICs. The 700V low Ron nLDMOS devices offer improved specific-on-resistance of 150 mohm·cm2, which is approximately 30% lower as compared with MagnaChip's previous-generation UHV technology. In addition, the devices enable various design schemes, including the possibility to separate or connect the source and the bulk in nLDMOS. The UHV device, which is structured to assign single power 30V to Vg and Vd, enables more simple circuits in product design.
Customers already have adopted MagnaChip's 0.35 micron 700V Ultra High Voltage Process Technology, with many engagements currently in the design stage.
YJ Kim, MagnaChip's Chief Executive Officer, commented, "Our 0.35 micron 700V Ultra High Voltage technology provides our foundry customers with a high-performance, highly efficient manufacturing process for AC-DC converter ICs and LED driver ICs for various industrial lighting applications." Mr. Kim added, "To meet diverse customer requirements, MagnaChip will continue to develop new UHV technologies such as customer-specific UHV processes and high-side UHV processes."
