1.   Burlington is where we manufacture some of our exclusive technologies such as silicon germanium, which allows for the production of higher performing chips.

2.   IBM executives predict that silicon germanium will put new competitive pressure on the current market for several exotic semiconductor technologies, including gallium arsenide.

3.   The substrate IBM is using is a material called silicon germanium.

4.   When used at lower speeds, silicon germanium consumes very little power, offering the possibility of extended battery life.
