Abstract: A head-mounted eye tracking system including a light-transmitting substrate, an eye tracker, and a signal processor is provided. The eye tracker is configured to sense eyeballs of a wearer. The eye tracker includes a plurality of light-emitting devices and a plurality of sensing devices. The plurality of light-emitting devices are configured to emit a tracking beam. The plurality of sensing devices are configured to receive the tracking beam reflected by the eyeballs of the wearer. The signal processor is electrically connected to the eye tracker. The plurality of sensing devices are embedded in grooves within the light-transmitting substrate.

Abstract: A semiconductor structure includes a source/drain feature in the semiconductor layer. The semiconductor structure includes a dielectric layer over the source/drain feature. The semiconductor structure includes a silicide layer over the source/drain feature. The semiconductor structure includes a barrier layer over the silicide layer. The semiconductor structure includes a seed layer over the barrier layer. The semiconductor structure includes a metal layer between a sidewall of the seed layer and a sidewall of the dielectric layer, a sidewall of each of the silicide layer, the barrier layer, and the metal layer directly contacting the sidewall of the dielectric layer. The semiconductor structure includes a source/drain contact over the seed layer.

Abstract: A production method combining cathode arc and magnetron sputtering methods to form an antibacterial film on the surface of an object. Inside the vacuum chamber, both a cathode arc target source and a magnetron sputtering target source are configured. On the cathode arc target source, at least one of a zirconium, titanium, or chromium target is installed. On the magnetron sputtering target source, a silver target is installed. Argon and nitrogen are filled into the vacuum chamber to respectively ionize the silver target and one of the zirconium target, titanium target, or chromium target. Remote control is used to adjust the ionization proportion between one of the zirconium, titanium, or chromium target and the silver target to be 90-99%:1-9%. The surface of the object is formed with one of the zirconium nitride-silver mixed antibacterial film, titanium nitride-silver mixed antibacterial film, or chromium nitride-silver mixed antibacterial film.
