New PowerMOSFET with Leading-Edge 0.25-Micron UMOS-5 Process Technology

Designed for Lithium-Ion Batteries, New MOSFET Delivers 30-Percent Performance Increase

NEC Electronics Europe and NEC Electronics America today introduced a high-performance power MOSFET fabricated with NEC Electronics’ newest and most advanced process technology for MOSFET. The new MOSFET will enable smaller and more powerful batteries to power the next generation of portable electronics devices. The 0.25-micron UMOS-5 process, one of the world's most advanced MOSFET technologies, enables a 30-percent smaller size compared to former technologies and an industry-leading low on-state resistance of 5.3 milliohms (mΩ) per mm square. This advanced battery protection solution will allow manufacturers to design powerful, cost-effective lithium-ion (Li-ion) batteries that can deliver higher output current while remaining protected against overheating.

The growing use of advanced features in cell phones, digital still cameras and portable game players has resulted in rapidly increasing power requirements for these portable consumer electronics devices. Battery manufacturers need cost-effective, small format components that deliver higher performance with lower power consumption levels. As a leading provider of power MOSFETs for Li-ion batteries, NEC Electronics remains committed to delivering high-performance, reliable devices to ease the development process and enable manufacturers to meet the demands for batteries to power the next generation of portable electronics devices.

NEC Electronics' UMOS-5 process technology represents a major advance as it allows dielectric layers of the same size as gate electrodes, for up to twice as much electrode area than  transistors of the same size in the previous UMOS-4 process. This helps battery manufacturers design low-cost, high-performance batteries in smaller packages, or higher performing batteries in packages of the same size. In addition, the low on-state resistance, 5.3 mOhm/mm², marks a new industry low in power MOSFET for Li-ion batteries.
