Patent number: 9176097Abstract: A welded portion quality determining system includes a first plate and a second plate, a welded portion defined at a point where the first plate and the second plate are welded to each other. Magnetic field generators generate a magnetic field to be supplied to the welded portion, and magnetic pickup devices receive the magnetic field generated by the magnetized welded portion to sense the received magnetic field. Therefore, a magnetic field may be generated by the welded portion through the magnetic field generators, and the magnetic field generated by the magnetized welded portion is sensed by the magnetic pickup devices so that quality of the welded portion may be rapidly and correctly verified.Type: GrantFiled: September 26, 2013Date of Patent: November 3, 2015Assignee: HYUNDAI MOTOR COMPANYInventor: Yong Joon Cho

Patent number: 7476622Abstract: A gate is formed on a device formation region of a semiconductor substrate, and source and drain regions are formed in the device formation region of the semiconductor substrate adjacent respective sides of the gate. The gate is formed to include a gate dielectric layer, a gate conductive layer and sidewall spacers located at respective sidewalls of the gate conductive layer. An etch stop layer is formed over the source region, the drain region and the sidewall spacers of the gate to obtain an intermediate structure, and a planarized first interlayer insulating film is formed over a surface of the intermediate structure. The first insulating layer is dry etched until the etch stop layer over the source region, the drain region and the sidewall spacers is exposed to form self-aligned contact holes in the first interlayer insulating over the source region and the drain region, respectively.Type: GrantFiled: November 14, 2003Date of Patent: January 13, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Yong-joon Cho, Young-hee Kim, Young-hwan Yun, Doo-heun Baek

Patent number: 6732750Abstract: A semiconductor wafer cleaning apparatus and method uses only one inner bath for chemical solution and de-ionized water cleaning, and includes a marangoni dryer for cleaning and drying semiconductor wafers. The apparatus includes a loading unit loaded with a cassette holding wafers; a moving mechanism for extracting the wafers from the cassette and moving the wafers into a loader; an inner bath for cleaning the wafers with a chemical solution or de-ionized water; a marangoni dryer including a hood, for moving the wafers from the loader into the bath, to be sealed to the bath; and a knife for supporting the wafers loaded into the bath at a lower portion thereof and moving the wafers up and down. Since the marangoni dryer is adhered to the bath during drying, the wafers are not affected by laminar flow or exhaustion and water marks do not occur thereon.Type: GrantFiled: April 11, 2001Date of Patent: May 11, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Yong-joon Cho, Seung-kun Lee, Young-hwan Yun, Gyu-hwan Kwag

Patent number: 6460269Abstract: A wafer dryer for drying a wafer includes a chamber and a support adapted to support the wafer in the chamber. A spray nozzle is disposed in the chamber. A source gas supply tank is in fluid communication with the spray nozzle. At least one heater is operable to heat the chamber and the source gas supply tank. A pumping line is in fluid communication with the chamber. Drive means are operable to rotate the chamber and the spray nozzle. A method for drying a wafer using a wafer dryer including a chamber and a revolving spray nozzle includes the steps of: loading the wafer in the chamber; reducing the pressure in the chamber in which the wafer is loaded to a near vacuum state; creating a temperature controlled atmosphere in the pressure-reduced chamber to quicken drying of the wafer; and spraying the source gas on the wafer while rotating the chamber and the revolving spray nozzle in opposite directions in the pressure-reduced temperature controlled atmosphere.Type: GrantFiled: March 6, 2001Date of Patent: October 8, 2002Assignee: Samsung Electronics Co., Ltd.Inventors: Yong-joon Cho, Gyu-hwan Kwag
