Abstract

This paper describes on thinning SDB SOI substrates by SDB technology and electrochemical etch-stop. The surface of the fabricated SDB SOI substrates is more uniform than that grinding or polishing by mechanical method, and this process is possible to accurate SOI thickness control. During Electrochemical etch-stop, leakage current versus voltage curves were measured for analysis of the open current potential (OCP) point and the passivation potential (PP) poin and determinated to anodic substrates were analyzed by using AFM and SEM, respectivelv.
