    • The present invention is directed to a spin chuck for use in a process, such as a cleaning process and an etching process, performed while rotating a substrate. The spin chuck includes a spin head on which a substrate is placed, a driving part configured to rotate the spin head, and a fix bracket installed on the spin head and having a contact surface that is in contact with a flat surface of a flat zone of the substrate at a position corresponding to the flat zone to prevent a vortex caused by the flat zone. Since the fix bracket has the same shape as the flat zone of the substrate, an air current unbalance resulting from the flat zone is suppressed to uniformly inject etchants to a rear surface of the substrate.
    • 本发明涉及一种旋转卡盘,用于在旋转基板的同时执行诸如清洁处理和蚀刻工艺的工艺。 旋转卡盘包括其上放置基板的旋转头,构造成旋转旋转头的驱动部分和安装在旋转头上的固定支架,并且具有与平坦区域的平坦表面接触的接触表面 在对应于平坦区域的位置处的基板,以防止由平坦区域引起的涡流。 由于固定支架具有与基板的平坦区域相同的形状,所以抑制了由平坦区域产生的气流不平衡,以将蚀刻剂均匀地注入基板的后表面。

    • Provided is a substrate-processing apparatus including a transfer member loading and taking out a substrate to and from a storage member, and a control unit controlling the transfer member. The transfer member includes a plurality of transfer arms and an arm-driving part moving the respective transfer arms horizontally, and substrates are loaded on the respective transfer arms. The control unit controls a movement velocity and a position of the transfer member and compares movement velocity profiles of the transfer arms, so as to control movement velocities of the respective transfer arms. Accordingly, the simultaneously driven transfer arms simultaneously arrive at target points, and thus the substrate-processing apparatus reduces transfer time and improves productivity.
    • 提供了一种基板处理装置,其包括将存储部件加载和取出基板的转印部件和控制转印部件的控制部。 转印构件包括多个转印臂和臂驱动部分,水平地移动各个转印臂,并且基板被装载在相应的转印臂上。 控制单元控制传送构件的移动速度和位置,并且比较传送臂的移动速度分布,以便控制各传送臂的移动速度。 因此,同时驱动的传送臂同时到达目标点,因此基板处理装置减少传送时间并提高生产率。

    • Provided is a method of adjusting a velocity of a transfer arm in a transfer member. The method includes, accelerating the transfer arm from a start point to a first point where a movement velocity reaches a preset reference velocity, dividing a division from the first point to a second point into movement divisions to move the transfer arm in any one of a deceleration motion, an acceleration motion, and a uniform motion according to the respective movement divisions, and decelerating the transfer arm from the second point to a target point. The motion of the transfer arm in the current movement division is different from that in the movement division just before the current movement division. Thus, a different impulse from that in the precedent movement division is applied to a substrate loaded on the transfer arm. Accordingly, the impulse response superposition cancels residual vibration of the substrate, so as to improve transfer efficiency of the transfer member.
    • 提供了一种调节传送构件中的传送臂的速度的方法。 该方法包括:将传送臂从起始点移动到移动速度达到预设参考速度的第一点,将从第一点到第二点的分割分成运动分割,以将传送臂移动到 减速运动,加速运动,以及根据各运动部分的均匀运动,以及将传送臂从第二点减速到目标点。 传动臂在当前运动部分中的运动与在当前运动分割之前的运动分割中的运动不同。 因此,与先前运动分割中的不同的脉冲施加到装载在传送臂上的基板。 因此,脉冲响应叠加抵消了基板的残余振动,从而提高了转印部件的转印效率。
