III-V on Si
The integration of III-V compound semiconductor materials such as GaAs on Si provides a unique opportunity to combine the advantages of advanced semiconductor materials with the capabilities of established silicon technologies.
Future high-performance ICs will require the monolithic integration of CMOS and III-V Compound Semiconductor (CS) devices to enhance the performance of existing Si CMOS processes through the addition of III-V capabilities.
III-V on silicon offers chip designers the “best junction for the function” without compromising the yield and scale of CMOS or the speed and breakdown of compound semiconductor materials.
Furthermore, a unique III-V on silicon platform will enable optical III-V devices to be fabricated on silicon substrates, creating a new class of high performance mixed-signal and digital IC’s
