MagnaChip Develops 0.35 Micron Bipolar/CMOS/DMOS Process
South-Korean based firm, MagnaChip Semiconductor Corporation now offers a second generation 0.35µm BCD (Bipolar/CMOS/DMOS) high voltage process technology.
This process supports applications from 3.3V to 65V making it ideally suited for DC-DC converters and regulators, Power-over-Ethernet, LED drivers, level shifters, audio amplifiers, AC-DC controllers and converters, micro-converters and micro-inverters, as well as PMICs for the mobile and consumer markets.
This second generation 0.35µm BCD process features high-voltage MOSFETs with 20 ~ 35 percent lower specific on resistance (Rsp) than the previous generation, achieved through process and device structure optimisation.
IC designs typically require a broad range of voltage schemes and reliability requirements. This new BCD process features an option to select DMOS devices which best optimise Rsp values for scaled reliability levels.
Besides featuring a lower Rsp, MagnaChip's proprietary deep-trench isolation technology yields about a five times smaller DMOS isolation area and much improved latch-up immunity, compared to conventional junction isolation approaches.
With the combination of lower Rsp, improved isolation and higher reliability, this next generation 0.35 µm BCD process will provide the firm's foundry customers with smaller and higher performance products.
This new technology supports MagnaChip's various process module options which enhance design flexibility and cost effectiveness. These options include multi-time programmable (MTP) and high-reliability non-volatile memory cells, one-time programmable (OTP) cells, high capacitance per unit area, metal-insulator-metal capacitor, copper wire bonding, thick top metal, and redistribution layer process options.
"We are very pleased to offer our next generation 0.35µm BCD high voltage process solution optimised for the fast growing mobile and consumer markets," says Namkyu Park , Vice President of Marketing for MagnaChip's foundry division. "As a specialty foundry, our goal is to continue to introduce process technology enhancements for our foundry customers that improve the performance and cost effectiveness of their products."
