  • Patent number: 11145733
    Abstract: The present invention discloses a method for forming a semiconductor device with a reduced silicon horn structure. After a pad nitride layer is removed from a substrate, a hard mask layer is conformally deposited over the substrate. The hard mask layer is then etched and trimmed to completely remove a portion of the hard mask layer from an active area and a portion of the hard mask layer from an oblique sidewall of a protruding portion of a trench isolation region around the active area. The active area is then etched to form a recessed region. A gate dielectric layer is formed in the recessed region and a gate electrode layer is formed on the gate dielectric layer.

  • Patent number: 10668323
    Abstract: A pedaling vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. A user can fully exercise muscles of the user's body during exercise, and a vibrational effect generated by the eccentric assembly can stimulate acupuncture points of the user's body to improve blood circulation. Left and right pedals of the pedal assembly can be treaded in turn to continuously drive a gear to rotate in a same direction so as to achieve an effect of acceleration and to enhance vibrations.
