  • Patent number: 12292815
    Abstract: A method for system profiling and controlling and a computer system performing the same are provided. In the method, an operating system is operated after the computer system is booted, in which a profiling-controlling system is operated. When the operating system loads and executes a system profiling-controlling program, the profiling-controlling system that simultaneously operates a profiling routine and a controlling routine is initiated. The profiling routine is used to retrieve system kernel data that is generated during operation of the operating system and analyze the system kernel data through a kernel tracing tool. When it is determined that controlling is required, the profiling routine notifies the controlling routine. The controlling routine controls operating parameters of the operating system in real time according to an analysis result generated by the profiling routine.

  • Publication number: 20250133808
    Abstract: Aspects of the disclosure provide a method for forming a fin field effect transistor (FinFET) incorporating a fin top hardmask on top of a channel region of a fin. Because of the presence of the fin top hardmask, a gate height of the FinFET can be reduced without affecting proper operations of vertical gate channels on sidewalls of the fin. Consequently, parasitic capacitance between a gate stack and source/drain contacts of the FinFET can be reduced by lowering the gate height of the FinFET.
