Abstract: A semiconductor device and a method of fabricating the semiconductor device are disclosed. The semiconductor device includes a substrate, a fin base disposed on the substrate, nanostructured channel regions disposed on a first portion of the fin base, a gate structure surrounding the nanostructured channel regions, a source/drain (S/D) region disposed on a second portion of the fin base, and an isolation structure disposed between the S/D region and the second portion of the fin base. The isolation structure includes an undoped semiconductor layer disposed on the second portion of the fin base, a silicon-rich dielectric layer disposed on the undoped semiconductor layer, and an air spacer disposed on the silicon-rich dielectric layer.

Abstract: The invention discloses a data storage system and managing method thereof. The data storage system according to the invention includes N storage devices, a backup memory and a controller where N is a natural number. Each storage device has a respective write cache. Once the data storage system suffers from power failure, the backup memory still reserves data stored therein. The controller receives data transmitted from an application I/O request unit, executes a predetermined operation for the received data to generate data to be written, transmits the data to be written to the write caches of the storage devices, duplicates the data to be written into the backup memory, and labels the duplicated data in the backup memory as being valid in response to a writing confirm message sent from the storage devices.

Abstract: An earphone-based voice transmission device. An earplug is placed inside a user's ear for collecting the voice generated by the eardrum. The voice is converted into an output electronic audio signal by a converter. Then, the output electronic audio signal is amplified and transmitted to a communication device for further transmission.
