Abstract:
A starting structure for forming a gate-all-around field effect transistor (FET) and a method of fabricating the gate-all-around FET. The method includes forming a stack of silicon nanosheets above a substrate forming an interfacial layer over the nanosheets depositing a high-k dielectric layer conformally on the interfacial layer. The method also includes depositing a layer of silicon nitride (SiN) above the high-k dielectric layer and performing reliability anneal after depositing the layer of SiN to crystalize the high-k dielectric layer.

Claim (Index 1):
A starting structure for performing reliability anneal on a high-k dielectric layer during the formation of a gate-all-around field effect transistor (FET), the structure comprising:\n a stack of nanosheets formed above a substrate, the nanosheets being comprised of silicon and being formed as three-dimensional structures; an interfacial layer formed over the nanosheets, the interfacial layer covering four sides that form a perimeter of a cross-section of the three-dimensional structure of each of the nanosheets; a high-k dielectric layer conformally formed on the interfacial layer; and a silicon nitride (SiN) layer formed above the high-k dielectric layer.
