Abstract: Methods and structures for modulating an inner spacer profile include providing a fin having an epitaxial layer stack including a plurality of semiconductor channel layers interposed by a plurality of dummy layers. In some embodiments, the method further includes removing the plurality of dummy layers to form a first gap between adjacent semiconductor channel layers of the plurality of semiconductor channel layers. Thereafter, in some examples, the method includes conformally depositing a dielectric layer to substantially fill the first gap between the adjacent semiconductor channel layers. In some cases, the method further includes etching exposed lateral surfaces of the dielectric layer to form an etched-back dielectric layer that defines substantially V-shaped recesses. In some embodiments, the method further includes forming a substantially V-shaped inner spacer within the substantially V-shaped recesses.

Abstract: A power adapter comprises a microprocessor, a wireless communication module, a relay, a circuit board, a casing, a power input end, and a power output end. The microprocessor generates a switching signal according to a wireless control signal. The wireless communication module receives the wireless control signal and transmits the wireless control signal to the microprocessor. An input end of the relay electrically coupled to the power input end receives an alternative current (AC) power, and a control end of the relay electrically coupled to the microprocessor receives the switching signal. The relay outputs the AC power from the input end to the output end of the relay electrically coupled to the power output end according to the switching signal. The structure of the power input end corresponds to a power outlet. The structure of the power output end corresponds to a power plug of an electrical appliance.
