저온공정을 통한 Pt-silicide SB-MOSFET의 전기적 특성과 공정기술에 관한 연구

In this work, we describe a method to fabricate the Pt-silicided SB-MOSFETs with a n-type Silicon-On-Insulator (SOI) substrate as an active layer and demonstrate their electrical and structural properties. The fabricated SB-MOSFETs have novel structure and metal gate without sidewall. The gate oxide with a thickness of 7 nm was deposited by sputtering. Also, this fabrication processes were carried out below $500^{\circ}C$. As a result, Subthreshold swing value and on/off ratio of Fabricated SB MOSFETs was 70 [mV/dec] and $10^8$.
