STMicroelectronics Rides the Crest of the Coming Motion-Sensing Consumer Wave

GENEVA, Jan. 15 /PRNewswire/ -- Market analyst iSuppli ranks ST No.1 in consumer and portable applications of motion-sensing chips:

- games controllers and smart phones fuel massive 118% growth in 2008

- ST jumps from No.4 to No.1 with revenues more than twice those of its closest competitor

GENEVA, Jan. 15 /PRNewswire-FirstCall/ -- Whether it is conducting a virtual symphony orchestra by waving a wireless baton, converting a dull physiotherapy exercise into an enjoyable interactive experience, or simply navigating through mobile phone menus by tilting the phone instead of pressing buttons, the motion-sensing technology known as MEMS (Micro-Electro-Mechanical Systems) is transforming the world of portable and consumer devices and STMicroelectronics (NYSE: STM) is leading this revolution. According to market analyst iSuppli, ST's sales of MEMS devices for portable and consumer devices, which are used in the Nintendo Wii, for freefall detection in PCs such as the Fujitsu Siemens ESPRIMO range, the Gyration Air Mouse, leading smart phones and many other new applications, surged from $96m in 2007 to more than $209m in 2008, a growth of 118% that makes ST the world's number one supplier in this exciting and rapidly growing market.

"This is a dramatic confirmation of our vision a few years ago when we decided to commit resources to developing a new type of MEMS technology, one that could enable the creation of innovative and exciting consumer applications," said Benedetto Vigna, Group Vice President and General Manager MEMS and Healthcare, RF and Sensor Product Division, STMicroelectronics. "Before 2006", Vigna noted, "MEMS sensors were used in a few applications such as airbag collision sensors but were too bulky, too power-hungry and too expensive to be used in consumer applications."

ST addressed the first two problems by innovative engineering, developing and patenting new MEMS structures that were smaller, more robust and required less electrical power to operate, while still delivering very high performance. To solve the third problem, the Company took the bold step in 2006 of investing over $40m to set up the world's most advanced MEMS production line. The 200mm (8 inch) wafer processing facility in Agrate, near Milan, was inaugurated in November 2006 and is fully dedicated to producing MEMS devices such as accelerometers, gyroscopes and pressure sensors.

"Because semiconductor devices are processed in parallel on circular wafers of silicon, a 50% increase in the wafer diameter more than doubles the number of chips that can be manufactured at the same time and also significantly reduces the cost per device", said Vigna. "Being the only MEMS manufacturer in the world with a 200mm production line meant we were able to assure our customers that we would be able to deliver accurate and reliable devices in the volumes and at the prices they needed to create exciting new consumer markets - and that is exactly what they have done."

Following the enormous success of its MEMS accelerometers that measure linear motion, ST has expanded its portfolio to include tiny MEMS gyroscopes. These detect and measure tilt and angular motion, making them ideal for use in even more sophisticated game controllers, virtual reality transducers, motion controls, pointing devices, and vehicle navigation functions such as dead-reckoning and map-matching.

Editor notes

MEMS technology differs importantly from other semiconductor technologies in that it exploits the mechanical as well as the electrical properties of silicon. In conventional silicon chips, electrons move within the silicon but the silicon itself does not move. However, silicon is stronger than steel and the techniques that are used to build microscopic silicon transistors can also be adapted to build microscopic silicon structures such as cantilevers, springs and even gears that are capable of physical movement.

This allows semiconductor manufacturers to build MEMS actuators, such as microscopic pumps and motors, and MEMS sensors that can detect and measure linear or circular motion. MEMS sensors are used in an ever-expanding range of applications:

    --  in games controllers and mobile phones, they allow simple and intuitive
        user interfaces based on physical movement instead of keyboards or
    --  in hard disk drives, they protect data by detecting freefall and moving
        the read head to a safe position before impact;
    --  in domestic appliances such as washing machines, they can detect
        abnormal vibration, allowing the machine to alter the spin speed to
        minimise wear and tear;
    --  in digital cameras, they allow images to be compensated for slight hand
    --  according to iSuppli's MEMS October 2008 Market Brief, ST is thought to
        be the sole supplier of accelerometers for the Apple iPhone 3G.
