    摘要: A process is provided for selective removal of one or more unwanted fins during FINFET device fabrication. In one aspect, the process includes: providing a conformal protective layer over multiple fin structures on a substrate; patterning one or more openings over the unwanted fin structure(s); and removing at least a top portion of the unwanted fin structure(s) exposed through the opening(s), the removing including removing at least a portion of the conformal protective layer over the unwanted fin structure(s) exposed through the opening(s). In enhanced aspects, the removing includes removing a hard mask from the at least one unwanted fin structure(s) exposed through the opening(s), and selectively removing semiconductor material of at least one unwanted fin structure(s). The conformal protective layer protects one or more remaining fin structures during the selective removal of the semiconductor material of the unwanted fin structure(s).

    摘要: An internal combustion engine is operated in accordance with a Miller cycle. The engine includes a piston disposed in the engine cylinder and configured to reciprocate between a top dead center position and a bottom dead center position of the engine cylinder. An air intake valve is coupled to the cylinder. The air intake valve is closed when the piston is about the bottom dead center position in the engine cylinder. An exhaust valve is coupled to the engine cylinder. The exhaust valve is opened for a predetermined time period when the piston is about the bottom dead center position of the engine cylinder after closing the intake valve so as to exhaust a predetermined quantity of fresh charge from the engine cylinder via the exhaust valve.
