초록
본 논문에서는 밀리미터파 응용에 사용 가능한 우수한 성능의 50 nm InGaAs/InAlAs/GaAs metamorphic HEMT를 구현하였다. 게이트 길이가 50 nm이며 단위 게이트 폭이 30 ㎛인 2개의 게이트를 가지고 있는 MHEMT의 측정결과, 740 mA/mm의 드레인 포화 전류밀도와 1.02 S/mm의 상호전달 전도도를 얻었으며 전류이득차단주파수와 최대공진주파수는 각각 430 GHz와 406 GHz의 특성을 나타내었다.
Abstract
We reported on a high performance InGaAs/InAlAs metamorphic HEMT with 50 nm gate length on a GaAs substrate. The fabricated 50 nm × 60 ㎛ MHEMT showed good DC and RF characteristics. Typical drain current density of 740 mA/mm and extrinsic transconductance(gm) of 1.02 S/mm were obtained with our devices. The current gain cut-off frequency(fT) and maximum oscillation frequency(fmax) obtained for the fabricated MHEMT device were 430 GHz and 406 GHz, respectively.)
