Analog and mixed-signal foundry Key Foundry (Cheongju, South Korea) was formed in 2020 by the buy-out of the foundry business and a 200mm wafer fab from MagnaChip Semiconductor Corp. (Seoul, South Korea) for approximately $450 million.
Key describes the new process as a third-generation 0.18-micron BCD that offers 20 percent improved performance over the previous generation. The process has lower on-resistance in DMOS and reduced parasitic capacitance.
The process is drawing interest from designers of dc/dc power converters, battery chargers, audio amplifiers and motor drivers, the company said. As the process is AEC-Q100 qualified it is also suitable for automotive power semiconductors such as a motor driver IC, a DC-DC IC, or battery management systems IC.
The process includes multi-time programming and one-time-programming memory IP without adding process steps. It also offers a dielectric process that insulates at 10kV or higher. The company is now developing further options, such as low operating voltage power devices, power PMOS with low ON-resistance for high-side circuits, and depletion-mode NMOS for startup circuits. These option devices are expected to be available in the 1H21.
"As the power semiconductor market is making a rapid growth recently, there are escalating demands for highly reliable and price-competitive foundry technologies," said Tae Jong Lee, CEO of Key Foundry, in a statement.
