Entrepreneur Bill Lee has been developing a new type of semiconductor process that makes tiny accelerometers. When embedded in devices these little machines could change the types of games played on cheap handsets or eliminate the spasm-like head nod used to activate Google Glass.
As the CEO of mCube, a five-year old startup, Lee has just raised a $37 million Series C round of funding from existing investors Kleiner Perkins Caufield & Byers, MediaTek, iD Ventures America, and DAG Ventures. New investors include Keytone Ventures, SK Telecom (China) Ventures and Korea Investment Partners, bringing the total money his startup has raised to $70 million.
Already mCube has shipped more than 60 million of its tiny microelectromechanical machines or MEMS. What’s novel about the company is how it builds them. A MEM is a type of semiconductor that is used to translate the physical aspects of our world (temperature, movement, light, pressure) and convert it into something digital our computers can read.
Making MEMS involves building a traditional silicon semiconductor and then wiring the analog-sensing component to the silicon. What mCube has figured out is how to make the...
