Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

Abstract: An artificial shuttlecock includes a ball head, a plurality of feathers, and a plurality of stems. Each of the feathers includes a notch. The notch is disposed on an outer edge of the feather. A ball head end of the stem is connected to the ball head, and a feather end is connected to the feather. The stem includes a body, which tapers from the end close to the ball end to the feather end. The end of the body close to the ball end has a first width, and the body has a second width at the feather. The first width is between 2.1 mm and 2.4 mm, and the second width is between 0.4 mm and 0.6 mm.

Abstract: The present disclosure provides an extreme ultraviolet (EUV) lithography system including a radiation source and an EUV control system integrated with the radiation source. The EUV control system includes a 3-dimensional diagnostic module (3DDM) designed to collect a laser beam profile of a laser beam from the radiation source in a 3-dimensional (3D) mode, an analysis module designed to analyze the laser beam profile, a database designed to store the laser beam profile, and an EUV control module designed to adjust the radiation source. The analysis module is coupled with the database and the EUV control module. The database is coupled with the 3DDM and the analysis module. The EUV control module is coupled with the analysis module and the radiation source.

Abstract: A display device and a method of applying the same are introduced herein. A shielding layer is utilized to interpose between a transparent conductive layer of a touch element and a common electrode layer of a liquid crystal display (LCD) panel. With controlling variances of a first and a second control signals, a coupling current between the transparent conductive layer and common electrode layer can approach none, whereby influences of capacitive coupling effect between the common electrode layer or shielding layer and the transparent conductive layer of the touch element can be reduced. Thus, high touch accuracy of the touch element can be achieved and the noise can be eliminated simultaneously.

Abstract: A touch panel includes a transparent conductive layer, a closed-loop electrode member circled around the transparent conductive layer, and a signal-transferring layer separated from the transparent conductive layer. The signal-transferring layer includes a transmission trace and a pad. The respective pads are located at four comers of the display device. Each transmission trace can conduct an electric current when an object contacts the transparent conductive layer. The signal-transferring layers and the electrode members are made of an identical conductivity material.
