  • Patent number: 10763114
    Abstract: A method of fabricating a semiconductor device includes forming a semiconductor fin comprising a channel region for a fin field effect transistor (finFET). A gate oxide layer is then formed on the channel. The gate oxide layer is treated with a nitrogen containing agent so as to form a nitrogenous layer and an interfacial layer. The nitrogenous layer is then removed. A high-k dielectric layer is formed on the interfacial layer. A metal gate is formed on the high-k dielectric layer. The nitrogenous layer is removed by rinsing the semiconductor fin with deionized water. The gate oxide and interfacial layer contains the same material.

  • Patent number: 10745532
    Abstract: The present disclosure relates to a generalized method for producing a vertically oriented block copolymer film, a block copolymer film with controlled orientation obtained thereby, and a method for producing a self-assembled pattern. According to the present disclosure, it is possible to form a crosslinked layer, which is mechanically stable and undergoes no chemical change, by subjecting the block copolymer surface to plasma treatment using a filter. It is also possible to obtain a vertically oriented block copolymer film by annealing the block copolymer film having such a crosslinked layer. The method for producing a vertically oriented block copolymer film according to the present disclosure is advantageous in that it can be applied for general purpose regardless of the chemical structure, type and morphology of a block copolymer, and the method can be applied generally to the conventional directed self assembly process.

  • Patent number: 10703411
    Abstract: An apparatus and method for assisting a vehicle into a desired position within a parking space. The device uses non-uniform light strength light line or other pattern projection to generate highlighted projections onto a target at a vehicle dashboard. The user may form a strong projection by focusing multi laser projections to overlap each other at the target. The driver knows the location of the vehicle by memorizing the patterns along the projections relative to the locations in the parking space. The driver maneuvers the vehicle direction and speed in order to make the projections onto the target, to avoid hitting the garage door frame, and to park on a desired position inside the parking space. The devices can be used for both guiding the vehicle into the parking space at a predetermined path to avoid nearby objects and stopping the vehicle at the desired place and direction.
