Abstract:
The manufacture of a FinFET device includes the formation of a composite sacrificial gate. The composite sacrificial gate includes a sacrificial gate layer such as a layer of amorphous silicon, and an etch selective layer such as a layer of silicon germanium. The etch selective layer, which underlies the sacrificial gate layer, enables the formation of a gate cut opening having a controlled critical dimension that extends through the composite sacrificial gate.

Claim (Index 6):
The method of  claim 1 , wherein forming the gate cut opening comprises etching the etch selective layer to form an undercut region that extends laterally beneath the sacrificial gate layer.
