We have developed 90nm InGaAs Channel HEMT process and compared the DC and RF performance to 90nm Si nMOSFET by direct measurement (shown in Table II). With nonself-aligned structure, comparable DC characteristics
and superior RF performance are already demonstrated. The extracted parameters together with logic figures of merit shows 90nm InGaAs HEMT has the promise of 2 times better performance compared to 90nm Si CMOS. This work contributes benchmark of III-V channel FET for beyond CMOS logic applications and provides insights for improvement in design layout and process development of III-V HEMT for logic applications
