Abstract :
A new SOI/bulk hybrid technology with devices on both the thin film and the bottom substrate of SIMOX wafers has been studied. By fabricating ESD protection circuits on the substrate of SIMOX wafers, ESD reliability of high performance CMOS SOI circuits can be significantly improved. Despite the higher surface defect density and micro-roughness on the bottom substrate of SIMOX wafers compared to ordinary bulk wafers, similar electron mobility, intrinsic thermal oxide properties and hot-carrier degradation are observed among MOSFET´s fabricated on the different substrates. Thus, the hybrid technology is capable of combining the advantages both of SOI and bulk technology in fabricating high performance circuits.<>
