Abstract: The present disclosure provides a method of forming a semiconductor device including an nFET structure and a pFET structure where each of the nFET and pFET structures include a semiconductor substrate and a gate trench. The method includes depositing an interfacial layer in each gate trench, depositing a first ferroelectric layer over the interfacial layer, removing the first ferroelectric layer from the nFET structure, depositing a metal oxide layer in each gate trench, depositing a second ferroelectric layer over the metal oxide layer, removing the second ferroelectric layer from the pFET structure, and depositing a gate electrode in each gate trench.

Abstract: A signal control module integrated to a low coherence interferometry including a one-dimensional (1D) array image sensor is provided. The signal control module includes an image acquisition controller and a signal controller. The image acquisition controller sends a 1D image acquisition control signal. The signal controller sends a two-dimensional (2D) image acquisition control signal, wherein the 1D and 2D image acquisition control signals are synchronized with each other. The 1D array image sensor captures 1D image information of an object-to-be-tested at different positions along a direction according to the 1D and 2D image acquisition control signals. The 1D image information constitutes 2D image information. Furthermore, a low coherence interferometry is provided.

Abstract: An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.

Abstract: An embodiment provides a video conference system including an audio processing unit, a video processing unit and a network processing unit. The audio processing unit encodes an audio signal to an audio stream. The video processing unit encodes a pause image to a first video stream when the video conference system is in a pause mode, and encodes a video signal to a second video stream when the video conference system is in a conference mode. The network processing unit encodes the first video stream to a first network package in the pause mode, and encodes the second video stream and the audio stream to a second network package in the conference mode.

Abstract: A nail-cleaning tool has a rod, a removing end, a scraping end and a sheath. The scraping end is spatula-shaped. The sheath is an absorbent material mounted over the removing end. Therefore, users can use the removing end to absorb nail polish remover then clean a surface of the nail during removal and application. The users can further use the scraping end to scrap an edge of each nail adjacent to skin. Therefore, the nail can be cleaned thoroughly while minimizing waste and reducing direct skin contact with the nail polish remover.
