Abstract: The present disclosure provides a semiconductor device, comprising: a substrate having a first semiconductor material; a second semiconductor layer on the substrate; a third semiconductor layer on the second semiconductor layer and being a device formation region; an isolation structure on both sides of the third semiconductor layer and on the substrate; and an hollow cavity below the source and drain regions of the third semiconductor layer and between the isolation structure and the ends of the second semiconductor layer. Such a device structure of the present disclosure incorporate the respective advantages of the bulk silicon device and the SOI device, and has characteristics of lower cost, smaller leakage current, lower power consumption, fast speed, simple process and high integration level. Meanwhile, the floating body effect and the spontaneous heating effect are eliminated as compared with the SOI device. Furthermore, the lower dielectric constant in the hollow cavity results in that it may withstand a higher voltage.
