Abstract:
Methods of forming a structure for a vertical-transport field-effect transistor. A semiconductor fin is formed over a sacrificial layer. A support structure is connected with the semiconductor fin. After forming the support structure, the sacrificial layer is removed to form a cavity extending beneath the semiconductor fin. A semiconductor material is epitaxially grown in the cavity to form a source/drain region of the vertical-transport field-effect transistor.

Claim (Index 7):
The method of  claim 6  wherein patterning the trench isolation layer to form the support structure comprises:\n depositing a dielectric material on the first section of the trench isolation layer and on the second section of the trench isolation layer; and \n after the dielectric material is deposited, removing a third section of the trench isolation layer that is arranged vertically over the sacrificial layer and horizontally between the first section of the trench isolation layer and the second section of the trench isolation layer, \n wherein the dielectric material masks the first section of the trench isolation layer and the second section of the trench isolation layer when removing the third section of the trench isolation layer.
