A method of manufacturing a flash memory device comprises forming a gate insulating layer on a semiconductor substrate, forming silicon seed crystals on a surface of the gate insulating layer by reacting a nitrogen or oxygen atmosphere gas and a silicon source gas, forming a first layer for a floating gate over the gate insulating layer and the silicon seed crystals by increasing an amount of the silicon source gas, and forming a second layer for a floating gate on the first layer for a floating gate.
摘要:
In one embodiment, a gate insulating layer, a conductive layer, and a metal layer are formed over a semiconductor substrate. An ion implantation region is formed in an interface of the conductive layer and the metal layer by performing an ion implantation process. A flash annealing process is performed on the ion-implanted semiconductor substrate. The metal layer, the conductive layer, and the gate insulating layer are patterned.
摘要:
A method and apparatus control a drum-type washing machine during a dewatering process in which a motor, coupled to a drum, rotates the drum to extract water from laundry contained in the drum. The method includes rotating the motor at a first rotating speed; performing at least one eccentricity detection at the first rotating speed, to obtain an eccentricity value; accelerating, if the obtained eccentricity value is within a nominal range, the motor from the first rotating speed to a second rotating speed, the second rotating speed being lower than a resonance range of the motor and rotated drum; and entering a main dewatering phase based on the at least one eccentricity detection. The second rotating speed of the motor is maintained at a constant level for a predetermined time before the main dewatering phase is entered. The constant level may be applied to a preliminary dewatering stage performed prior to the first rotating speed acceleration.

A heater fixing unit of a drum-type washing machine is provided. The heater fixing unit more stably supports a heater installed in a dry duct to reduce vibration and a noise of the heater. For that purpose, the heater fixing unit includes a duct body, a heater, two or more fixing parts, and two or more clamp members. The duct body communicates with an inside of the drum. The heater is installed in an inside of the duct body to heat an air flowing in an inside of the duct body. The fixing parts protruded from two or more positions on an inner surface of the duct body. The clamp members fixedly support the heater.
