Application: Method of manufacturing a semiconductor device and a semiconductor device (Patent ID: US20230411215A1)

The patent filed by Taiwan Semiconductor Manufacturing Co Ltd describes a method for manufacturing a semiconductor device involving the formation of multiple semiconductor layers with varying compositions over a substrate. These layers are then patterned to create a fin structure, from which a nanowire is formed by removing a portion of one of the layers. The resulting nanowire is surrounded by a conductive material. The semiconductor layers consist of different materials, with specific concentrations of Si and Ge in each layer.

The semiconductor device described in the patent consists of a stack of semiconductor layers arranged perpendicular to the substrate, with a gate electrode layer wrapping around them. Each semiconductor layer comprises inner and outer layers made of Si and Ge, with different concentrations of these elements. The inner layer is thicker than the outer layers, and the overall structure includes insulating sidewalls, a bottom fin structure, and a high-k dielectric layer. Another embodiment of the device involves a gate structure wrapping around the semiconductor layers, with the layers consisting of different Group IV elements and specific thickness ranges for each layer. The device also includes insulating sidewalls and a high-k dielectric layer for improved performance.
