Abstract
Semiconductor structures and methods of manufacture are disclosed herein. Specifically, disclosed herein are methods of manufacturing a high-voltage metal-oxide-semiconductor field-effect transistor and respective structures. A method includes forming a field-effect transistor (FET) on a substrate in a FET region, forming a high-voltage FET (HVFET) on a dielectric stack over a over lightly-doped diffusion (LDD) drain in a HVFET region, and forming an NPN on the substrate in an NPN region.
