Compared to mobile and vehicle demand
In September of last year, KeyFoundry, which was separated from MagnaChip, started diversifying its customers through new services. It is interpreted as a strategy to secure several fabless companies as new customers amid the recent shortage of foundry supply.
Key Foundry announced on the 9th that it will supply the 3rd generation 0.18 micrometer (㎛) BCD process service. BCD (Bipolar-CMOS-DMOS) process is a technology that implements △Bipolar process for analog signal control, △CMOS process for digital signal control, and △DMOS process for high power processing on one chip. It is used in the production of various power semiconductor products.
The 3rd generation BCD is a 20% improvement over the previous generation. Switching losses are reduced by implementing the low operating resistance and parasitic capacitance of the 8-40 volt (V) class power NMOS and PMOS. It is an optimized process for chips where power efficiency is important. It satisfies the AEC-Q100 Level 1 level, the reliability evaluation regulation for automobile electronic components. It is suitable for the production of power semiconductors for vehicles such as motor drive IC, battery management system (BMS), and DC-DC IC.
The BCD process is developing products with power semiconductor design companies in Asia and the Americas. Keyfoundry said, “We are receiving attention from chip design companies such as DC-DC ICs and driving chips for vehicles.”
It also provides design assets (IP) to choose from for the 3rd generation 0.18㎛ BCD process technology. To provide technology suitable for various products. An insulating film process that operates above 10 kilovolts (kV) is also provided so that power IC products can include the electrostatic isolator function.
In addition, devices such as low driving voltage power devices, low resistance power PMOS for high-side circuits, and depletion-type NMOS for startup circuits are under development. It is expected to be available during the first half of this year.
Tae-Jong Lee, CEO of KeyFoundry said, “As the power semiconductor market is growing rapidly, the demand for foundry technology with high reliability and cost competitiveness is steadily increasing.” I will let you go.”
Key Foundry was launched as a foundry specialized semiconductor company by spin-off from MagnaChip Semiconductor on September 1 of last year. It was created after a special purpose company (SPC) established by a domestic private equity fund management company in March last year acquired MagnaChip Semiconductor’s foundry business and Cheongju plant (Fab 4). At that time, SK Hynix also participated as a fund investor of Magnachip and became a hot topic. Representative Lee Tae-jong joined MagnaChip in 2007 and has been in the position of vice president and has been in charge of the entire business since the launch of KeyFoundry.
