Smart Foundry for Smart Society

Mie Fujitsu Semiconductor is a foundry partner that guides customers ľ businesses towards success by providing technology, customization, and support. Through the creation of new high value-added technologies and accumulated technologies such as ultra-low power consumption and embedded memory processes, we contribute to the realization of the IoT world and a sustainable society in which people and technology live in harmony.

World Technology Service


Ultra-Low Power Technology

In order to achieve the ultra-low power consumption that is necessary for mobile and wearable devices, we developed the "C55DDC" technology. "C55DDC" is a technology having transistors that can operate at ultra-low voltage and ultra-low leak transistors. These transistors adopt a structure that is different from conventional CMOS in order to achieve ultra-low power consumption.

As a result, the "C55DDC" achieves a reduction in power consumption of approximately 50% at the same operating speed when compared to the "C55LP". Furthermore the leakage current of the ultra-low leak transistors has been decreased to pico-ampere levels, and even to femto-ampere levels.

DDC transistor structure

The Deeply Depleted Channel (DDC) technology for 55 and 40nm can be shortly summarized as:

DDC = FD-SOI features @ 55nm/40nm wafer cost

Plugin Flash

MIFS is adding a plugin Flash option to the DDC processes. Plugin Flash comes with two advantages. Beside lower cost this option also provides lower power compared with conventional embedded Flash technologies.

Nonvolatile memories

Nonvolatile memories are embedded in a variety of electrical equipment such as automobiles, IC cards, smart meters, etc. We mount nonvolatile memories with high CMOS compatibility our customers' products at the lowest cost.


Wireless communication is a key word in the rapidly progressing IoT society. Our ULP/LP technology comes with PDK and the devices necessary for RF design (such as varactors, inductors, and MOM/MIM capacitors), allowing us to provide optimal RF solutions to our customers.

Wafer fab

Mie Fujitsu Semiconductor inherited the Mie 300mm fab from Fujitsu Semiconductor Limited. The fab started operations in 2005.

From the beginning of operations, this fab has been mainly providing foundry services for the advanced logic LSIs, and has established manufacturing, information management, quality control, and customer support systems for the foundry business In accordance with ISO14001.

According to the ISO9000 series and automotive ISO/TS16949 certifications, the wafer fab has established quality assurance and control systems.
