    • A megasonic cleaner includes a rotatable wafer supporting member for supporting a wafer; a cleaning solution supply member for supplying a cleaning solution to a wafer placed on the wafer supporting member; at least two vibration transfer members for agitating cleaning solutions supplied to different areas of the wafer placed on the wafer supporting member; and a vibration generating member for oscillating the at least two vibration transfer members. The cleaner has at least two quartz rods for transferring oscillation energy. Using the quartz rods, oscillation energy is transferred to respective areas of a wafer to clean the wafer. Thus, a difference between cleaning efficiencies of wafer edge and center is reduced or substantially eliminated to achieve a uniform cleaning efficiency on an entire surface of the wafer.
    • 兆声波清洗器包括用于支撑晶片的可旋转晶片支撑构件; 清洁溶液供给构件,用于将清洁溶液供给到放置在晶片支撑构件上的晶片; 至少两个振动传递构件,用于搅拌提供给放置在晶片支撑构件上的晶片的不同区域的清洁溶液; 以及用于振荡所述至少两个振动传递构件的振动产生构件。 清洁器至少有两个用于传递振荡能量的石英棒。 使用石英棒,将振荡能量转移到晶片的相应区域以清洁晶片。 因此,晶片边缘和中心的清洁效率之间的差异被减小或基本消除,以在晶片的整个表面上实现均匀的清洁效率。

    • A preparation method of a polyamide thin film composite reverse osmosis membrane and a polyamide thin film composite reverse osmosis membrane prepared using the preparation method are provided. The preparation method of a polyamide thin film composite reverse osmosis membrane using interfacial polymerization of an amine aqueous solution and amine-reactive compound includes the steps of (a) forming an active layer through interfacial polymerization by contacting a surface of a porous support with an amine aqueous solution containing a polyfunctional aromatic amine monomer and an organic solution containing polyfunctional acyl halide monomer as an amine-reactive compound, and (b) performing post-treatment preceded by the forming of the active layer by contacting the active layer with an aqueous solution containing 0.1 to 100 wt % of polyfunctional tertiary alcohol amine. The polyamide thin film composite reverse osmosis membrane prepared by using the polyfunctional tertiary alcohol amine as a post-treatment compound has improved water permeability and salt rejection compared to a case of using various post-treatment agents or methods.
    • 提供了使用该制备方法制备的聚酰胺薄膜复合反渗透膜和聚酰胺薄膜复合反渗透膜的制备方法。 使用胺水溶液和胺反应性化合物的界面聚合的聚酰胺薄膜复合反渗透膜的制备方法包括以下步骤:(a)通过界面聚合形成活性层,通过使多孔载体的表面与胺 含有多官能芳族胺单体的水溶液和含有多官能酰卤单体作为胺反应性化合物的有机溶液,和(b)在活性层形成之前进行后处理,所述活性层通过使活性层与含有 0.1〜100重量%的多官能叔胺胺。 通过使用多官能叔醇胺作为后处理化合物制备的聚酰胺薄膜复合反渗透膜与使用各种后处理剂或方法的情况相比,具有改善的透水性和耐盐析性。
