STMicroelectronics Rides the Crest of the Coming Motion-Sensing Consumer Wave
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
“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
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
“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.
STMicroelectronics is a global leader in developing and delivering semiconductor solutions across the spectrum of microelectronics applications. An unrivalled combination of silicon and system expertise, manufacturing strength, Intellectual Property (IP) portfolio and strategic partners positions the Company at the forefront of System-on-Chip (SoC) technology and its products play a key role in enabling today’s convergence markets. The Company’s shares are traded on the New York Stock Exchange, on Euronext Paris and on the Milan Stock Exchange. In 2007, the Company’s net revenues were
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 buttons;
- 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 movement;
