Fabricating method of transistor |
摘要 |
A fabricating method of a transistor is provided. A patterned sacrificed layer is formed on a substrate, wherein the patterned sacrificed layer includes a plurality of openings exposing the substrate. By using the patterned sacrificed layer as a mask, a doping process is performed on the substrate, thereby forming a doped source region and a doped drain region in the substrate exposed by the openings. A selective growth process is performed to form a source and a drain on the doped source region and the doped drain region, respectively. The patterned sacrificed layer is removed to expose the substrate between the source and the drain. A gate is formed on the substrate between the source and the drain. |

1. A fabricating method of a transistor, comprising:
forming a patterned sacrificed layer on a substrate, wherein the patterned sacrificed layer includes a plurality of openings exposing the substrate; by using the patterned sacrificed layer as a mask, performing a doping process on the substrate, thereby forming a doped source region and a doped drain region in the substrate exposed by the openings; performing a selective growth process to form a source and a drain on the doped source region and the doped drain region, respectively; removing the patterned sacrificed layer to expose the substrate between the source and the drain; and forming a gate on the substrate between the source and the drain, wherein a height of the gate is substantially the same as a height of the source and the drain. |
