  • Publication number: 20250089324
    Abstract: A gate oxide layer for a high voltage transistor is formed using methods that avoid thinning in the corners of the gate oxide layer. A recess is formed in a silicon substrate. The exposed surfaces of the recess are thermally oxidized to form a thermal oxide layer of the gate oxide layer. A high temperature oxide layer of the gate oxide layer is then formed within the exposed surfaces of the recess by chemical vapor deposition. The combination of the thermal oxide layer and the high temperature oxide layer results in a gate oxide layer that does not exhibit the double hump phenomenon in the drain current vs. gate voltage curve. The high temperature oxide layer may include a rim that extends out of the recess.

  • Publication number: 20250063758
    Abstract: A titanium precursor is used to selectively form a titanium silicide (TiSix) layer in a semiconductor device. A plasma-based deposition operation is performed in which the titanium precursor is provided into an opening, and a reactant gas and a plasma are used to cause silicon to diffuse to a top surface of a transistor structure. The diffusion of silicon results in the formation of a silicon-rich surface of the transistor structure, which increases the selectivity of the titanium silicide formation relative to other materials of the semiconductor device. The titanium precursor reacts with the silicon-rich surface to form the titanium silicide layer. The selective titanium silicide layer formation results in the formation of a titanium silicon nitride (TiSixNy) on the sidewalls in the opening, which enables a conductive structure such as a metal source/drain contact to be formed in the opening without the addition of another barrier layer.
