Abstract:
A method of forming a semiconductor line from a semiconductor-on-insulator (SOI) wafer, the SOI wafer having a substrate with a buried oxide (BOX) layer disposed thereon and a semiconductor active layer disposed on the BOX layer, comprising the steps of:(a) forming a dummy island on the active layer; (b) forming a sidewall spacer adjacent the dummy island; (c) removing the dummy island; (d) removing semiconductor material of the active layer left exposed by the sidewall spacer; (e) removing the sidewall spacer; (f) masking the semiconductor material remaining after step (e) with a mask; (g) patterning the mask to expose a portion of the semiconductor material remaining after step (e); (h) removing semiconductor material of the active layer left exposed after step (g); and (i) removing the mask.
