Ultra-thin-body (UTB) Ino.53Gao.47As-on-insulator (Ino.53Gao.47As-OI) structures with thicknesses of 8 and 15nm are realized by transferring epitaxially grown Ino.53Gao.47As layers to silicon substrates with 15-nm-thick Al2O3 as a buried oxide by using the direct wafer bonding method. Back gate n-channel metal-oxide-semiconductor field-effect transistors (nMOSFETs) are fabricated by using these Ino.53Gao.47As-OI structures with excellent electrical characteristics. Positive bias temperature instability (PBTI) and hot carrier injection (HCI) characterizations are performed for the Ino.53Gao.47As-OI nMOSFETs. It is confirmed that the Ino.53Gao.47As-OI nMOSFETs with a thinner body thickness suffer from more severe degradations under both PBTI and HCI stresses. Moreover, the different evolutions of the threshold voltage and the saturation current of the UTB Ino.53Gao.47As-OI nMOSFETs may be due to the slow border traps. [ABSTRACT FROM AUTHOR] |
