Fabrication of thick BOX SOI by Smart-cut technology

摘要

A SOI material with thick BOX (2.2 μm) was successfully fabricated using the Smart-cut technology. The thick BOX SOI microstructures were investigated by high resolution cross-sectional transmission electron microscopy (XTEM), while the electrical properties were studied by the spreading resistance profile (SRP). Experimental results demonstrate that both structural and electrical properties of the SOI structure are very good.
