Abstract

In this work investigates hot carrier stress on the RF power of SOI MOSFET using load-pull measurement. We found that the RF power characteristics are affected by the hot carrier stress, and the DC performance of SOI MOSFET is clearly degraded after hot carrier stress at constant voltage measurement. And these experimental observations can be explained by the change of DC performance degradation coefficient under hot carrier stress.

본 연구에서는 load-pull 장비를 이용하여 hot carrier 현상에 따른 RF 전력 성능 저하를 측정 분석하였다. 스트레스를 인가한 주에 RF 전력 지수들은 감소하였으며, 고정 전압 조건에서 관찰한 SOIl MOSFET의 DC 성능 지수들 또한 hot carrier stress로 인하여 감소함을 할 수 있었다. 또한 Hot carrier stress로 인한 DC 성능 저하로 인하여 RF 전력 성능 저하의 감소를 알 수 있었다.
