This new mixed signal process incorporates advantages such as 1.8V n and p-channel MOSFETs with low leakage current (~10 pA per micron of width) and low threshold voltage (Vth of only ~|0.3V|), which enable system on a chip designs to perform with very low active and low stand-by power consumption. MagnaChip's 0.18 micron low power process also enables DC-DC boost converters to be optimized for IoT applications, with very low start-up voltage.
This new process will also enable efficient operation of IoT devices from power sources such as solar cells, thermoelectric generators, vibration energy harvesters and electromagnetic harvesters. Another unique advantage of this process is the excellent device isolation and low current gain of parasitic bipolar transistors (less than 0.01), giving it better latch-up immunity and less leakage current over temperature and voltage. This is achieved through the use of conventional, lower cost silicon wafers instead of the more expensive silicon on insulator wafers.
The new 0.18 micron low power process will also support premium features available on MagnaChip's standard logic processes including low noise transistors for analog blocks, high k metal-insulator-metal capacitor, copper wire bonding compatibility, low cost aluminum top metallization as well as redistribution layer (RDL) process options.
"We are very pleased to offer our new 0.18 micron mixed-signal process solution incorporating features that support low power IoT applications while also minimizing customer costs," said Namkyu Park, Executive Vice President of MagnaChip's Semiconductor Manufacturing Services Division. "We are constantly working on leading-edge solutions to meet the ever increasing technology requirements of our customers and plan to continue to enable our partners with more options to cover their specific needs."
