Abstract

This paper describes on an advanced technology of 3C-SiC/Si(100) wafer direct bonding using PECVD oxide to intermediate layer for SiCOI(SiC-on-Insulator) structure because it has an attractive characteristics such as a lower thermal stress, deposition temperature, more quick deposition rate and higher bonding strength than common used poly-Si and thermal oxide. The PECVD oxide was characterized by ATR-FTIR. The bonding strength with variation of HF pre treatment condition was measured by tensile strength measurement system. After etch-back using TMAH solution, roughness of 3CSiC surface crystallinity and bonded interface was measured and analyzed by AFM, XRD, and SEM respectively.
