Abstract:
An apparatus for treating a substrate is provided to effectively perform a cleaning process and to realize the cost reduction by preventing attachment of impurities to the substrate. An apparatus for treating a substrate includes a conveying means(111) and a cleaning nozzle(116). A substrate(G) to be processed is loaded on a convey passage(32). The conveying means conveys a substrate to be processed to a predetermined direction through the convey passage. The cleaning nozzle supplies cleaning solution to an upper surface of the substrate to be processed. The convey passage includes a horizontal portion conveying the substrate to be process in a horizontal state and an oblique portion forms an upward slope of a predetermined angle from the horizontal portion. The cleaning nozzle is disposed in an upward direction of the oblique portion.

본 발명에 따른 초음파 세정 장치는, 세정액을 저류하는 세정조와, 세정조 내에 삽입 가능하게 설치되고, 피처리체를 유지하여 세정액에 침지시키는 피처리체 유지 장치와, 세정조의 바닥부에 설치된 진동자와, 진동자에 초음파 진동을 발생시키는 초음파 발진 장치를 구비하고 있다. 세정조 내에는 피처리체를 유지하는 측부 유지 부재가 설치되어 있다. 또한, 피처리체 유지 장치는, 구동 장치에 의해 측방으로 이동하도록 되어 있다. 제어 장치는, 피처리체를 측부 유지 부재에 유지시킨 후, 피처리체 유지 장치를 측방으로 이동시키도록 구동 장치를 제어하고, 진동자에 초음파 진동을 발생시켜 진동자로부터의 초음파 진동을 피처리체에 전파시키도록 되어 있다.
Abstract:
PURPOSE: An ultrasonic cleaning device, an ultrasonic cleaning method, and a recording medium with a computer program are provided to uniformly clean an object by successively moving a first wafer maintaining unit and a second wafer maintaining unit. CONSTITUTION: An object maintaining device(21a,21b) is installed in a cleaning bath(10) and maintains an object to be immersed in cleaning solutions. The object maintaining device includes a first object maintaining unit and a second object maintaining unit. A side maintaining unit is installed in the cleaning bath and maintains the object. A control device(44) controls an ultrasonic oscillator and a driving device. The driving device maintains the object on the side maintaining unit and then moves the side maintaining unit to the side. An ultrasonic oscillator transmits the ultrasonic vibration from a vibrator to the object.
