  • Patent number: 9966267
    Abstract: A method of manufacturing a semiconductor device which can prevent leakage current caused by gate electrodes intersecting element isolation layers in a major axis of an active region, and which further has vertical channels to provide a sufficient overlap margin, and a semiconductor device manufactured using the above method. The device includes gate electrodes formed on element isolation layers that are disposed between active regions and have top surfaces that are higher than the top surfaces of the active regions. Since the gate electrodes are formed on the element isolation layers, leakage current in a semiconductor substrate is prevented. In addition, the gate electrodes are formed using a striped shape mask pattern, thereby obtaining a sufficient overlap margin compared to a contact shape or bar shape pattern.

  • Publication number: 20170297560
    Abstract: A method of decreasing vibration during release of a stop gear of a vehicle can be applied to an eco-friendly vehicle for decreasing vibration generated when a driver releases a P step of a gear lever while torsion occurs in a drive shaft of the vehicle. Reaction force torque of a driving motor is controlled so as to output reaction force that has been generated in a parking sprag by a driving motor when torsion occurs in the drive shaft after entrance of the gear lever into the P step, so as to decrease vibration generated because torsion reaction force of the drive shaft vanishes at the same time.
