MagnaChip targets LED drivers with 0.35 micron 700V technologies

High voltage technologies for AC/DC converter ICs and LED driver IC are offered by MagnaChip as the company announces 0.35 micron 700V high voltage process technologies.

To meet the current market demand for AC-powered products, including LED lighting drivers, AC/DC converter ICs and AC/DC chargers, and the subsequent increased competition for high voltage technologies, MagnaChip has reduced device sizes of UHV nLDMOS by 30 per cent and JFET by 50 per cent from its previous generation.

The HP35ULC700 technology shortens the manufacturing process and reduces cost by having seven photolithographic steps less than the company’s previous generation. This was achieved by simplifying the front end process and reducing the minimum metal number from two to one, explains MagnaChip.

To cover the system and IC requirements, MagnaChip offers multiple ultra high voltage (UHV) technologies in terms of gate oxide schemes. When high system integration is necessary, dual gate oxide UHV technology can be used to provide the optimised low voltage, high voltage, and ultra-high voltage devices, says MagnaChip.  When manufacturing cost is important and control logic device density is high, low-voltage single-gate oxide UHV technology can be used. When manufacturing cost is important and superior high-voltage performance to drive external discrete high voltage MOSFETs is necessary, high voltage, single-gate oxide UHV technology can be used.

Devices with different operation voltages from 350 to 700V are provided, in recognition of the fact that AC/DC converter voltage requirements vary by country. Additional option devices that can enable the integrated AC/DC converter ICs and LED driver ICs are 700V nLDMOS integrated with 700V JFET, Zener diode, 700V resistor, thin film resistor, MIM capacitance and fuse.

MagnaChip Semiconductor designs and manufactures analogue and mixed-signal semiconductor devices for communications, IoT, consumer, industrial and automotive applications. The Standard Products Group and Foundry Services Group provide products and manufacturing services to customers worldwide.
