This requires a trick opposite to the first one-suddenly making an insulator into a conductor. The insulator in question is silicon carbide.

其关键技术与第一个恰好相反，它是将绝缘体迅速转为导体，其中所用的绝缘体是金刚砂。

SOI refers to the use of a layered silicon-insulator-silicon substrate in IC manufacturing, which is said to reduce parasitic device capacitance and improve performance.

SOI指的是在IC的制造过程中采用硅+绝缘层+硅的硅基体结构方式，这种结构方式的优势是可以减小器件的寄生电容并改善器件的性能。

Glasslike silicon dioxide has been the insulator of choice in electronic chips since 1959, when Bob Noyce cobbled together the first silicon integrated circuit--wires and switches etched into silicon insulation.

But silicon-on-insulator, first used in costly satellite and military applications, is practical for only high-end chips.

The consortium's technology builds its transistors inside a sliver of pure silicon, laid on top of an insulator, which in turn sits on top of a standard wafer, the substrate on which transistors are constructed.
