Abstract:
1. A method for manufacturing a semiconductor device, the method comprising the steps of: (a) forming a supporting material layer on an insulating layer; (b) forming a semiconductor material layer on the supporting material layer; (c) forming a patterned photoresist layer on the semiconductor material layer; (d) patterning the supporting material layer and the semiconductor material layer by using the patterned photoresist layer as mask, wherein the patterned semiconductor material layer is formed with a channel structure having a channel bridge; (e) removing the patterned photoresist layer; (f) removing a portion of the supporting material layer below the channel bridge to form two supporting pillars, wherein the channel structure is formed on the supporting pillars, and a bottom of the channel bridge is separated from the insulating layer by a distance; and (g) forming a plurality of separated doping regions used as source/drain regions between the supporting pillars.
