图2A和图2B是示出根据示例实施例的光掩模盒的分解透视图。
参考图2A和图2B,光掩模盒220可以包括标线式标准机械接口卡匣(reticlestandard mechanical interface pod,RSP)。光掩模盒220可以包括底座221、板223和盖225。
底座221可以被配置为支撑和容纳板223。四个支柱222可以被安装在底座221的上表面上。四个支柱222可以被配置为支撑板223。四个支柱222可以被配置为支撑板223。四个支柱222可以以均匀的间隙按矩形形式来布置,以保持板223的平整度。例如,四个支柱222可以被定位在板223的拐角处。用于组合盖225的导向槽和固定突起221a可以被形成在底座221的侧壁的边缘部分处。
光掩模M可以被放置在板223的上表面上。板223可以被定位在四个支柱222上。
盖225可以与底座221组合。例如,盖225可以具有用于覆盖底座221的尺寸。盖225可以形成被配置为容纳板223的空间‘s’。空间s可以具有台阶形状。盖225可以包括下盖225a、上盖225b和窗口225c。
下盖225a可以包括形成在下盖225a的底表面处的导向件‘g’。底座221可以与下盖225a的导向件g组合。通过旋转下盖225a,下盖225a可以与底座221的边缘部分处的导向槽组合。例如,下盖225a的内壁可以与底座221的边缘部分接触。
上盖225b可以被布置在下盖225a上,以形成空间“s”的深部。板223可以被定位在深部中。
窗口225c可以被布置在上盖225b上。窗口225c可以包括诸如塑料的半透明材料。可以通过窗口225c来识别板223上的光掩模M。
曝光设备200中使用的光掩模盒220可以被装载在检查设备100中。检查设备100可以检查光掩模盒220。
图3是示出根据示例实施例的用于检查光掩模盒的设备的横截面图,图4是示出根据示例实施例的驱动单元的透视图,而图5是示出根据示例实施例的驱动单元的横截面图。
参考图3至图5,检查设备100可以包括检查块110和控制块190。
检查块110可以包括装载端口120和驱动单元150。
光掩模盒220可以被装载到装载端口120上。
驱动单元150可以被布置在装载端口120下方。驱动单元150可以包括支撑板152、支撑轴C、动力供应器158和扭矩传感器160。
支撑板152可以被配置为支撑光掩模盒220的底表面。载物台ST可以位于支撑板152的中心部分。载物台ST可以被连接至支撑轴C。载物台ST可以根据支撑轴C的旋转方向而被旋转和驱动。至少一个打开/关闭销153可以被布置载物台ST上。打开/关闭销153可以被插入在形成于载物台ST中的凹槽H中。借助于打开/关闭销153与光掩模盒220的底座221接触,打开/关闭销153可以在凹槽H中移动。因此,可以旋转底座221,以将光掩模盒220的盖225与底座221彼此分开。
支撑板152可以包括至少两个位移传感器155。位移传感器155可以被布置在对应的位置处。位移传感器155可以被定位在支撑板152上的与底座221的拐角相对应的部分处。
图6是示出根据示例实施例的位移传感器的视图。
参考图6,位移传感器155可以包括朝向支撑板152的表面突出的销155a。例如,突出销155a可以具有弹性和稳定性。当光掩模盒220的底座221可以被放置在位移传感器155上时,突出销155a的长度可以根据光掩模盒220的平整度而改变。例如,当光掩模盒220的底座221可以被向右扭曲时,位移传感器155的与光掩模盒220的扭曲部分相对应的突出销155a的长度可以长于其他突出销155a的长度。
支撑轴C可以被布置在支撑板152的下方。例如,支撑轴C可以被布置在载物台ST的下方。可以通过动力供应器158来使支撑轴C上下移动。此外,支撑轴C可以承受动力供应器158的旋转力。因此,载物台ST和打开/关闭销153可以根据支撑轴C的旋转沿着支撑轴C的旋转方向来旋转。光掩模盒220的与打开/关闭销153接触的底座221可以通过打开/关闭销153和载物台ST的旋转而旋转,以将底座221与盖225分开。可以根据光掩模盒220的组装或拆卸来改变支撑轴C的旋转方向。
扭矩传感器160可以被安装在支撑轴C和动力供应器158之间。扭矩传感器160可以具有非旋转类型。扭矩传感器160可以被串接至支撑轴C。
图7是示出根据示例实施例的扭矩传感器的视图。在图7中,支撑轴C和扭矩传感器160可以在垂直方向上彼此串接。
参考图7,扭矩传感器160可以测量与扭矩传感器160串接的支撑轴C的旋转角度或扭转角度。例如,当支撑轴C的旋转角度可以小于参考旋转角度时,可以增加施加到支撑轴C上的负荷。相反,当支撑轴C的旋转角度可以大于参考旋转角度时,可以减小施加到支撑轴C的负荷。此外,当在打开/关闭光掩模盒220的过程中施加到支撑轴C的负荷可以小于或大于参考旋转角度时,可以注意到,光掩模盒220的底座221可以向上或向下扭曲。
控制块190可以将由扭矩传感器150测得的负荷和由位移传感器155获得的突出销155a的长度数字化,以确定光掩模盒220的平整度。
图8是示出根据示例实施例的控制块的框图。
参考图8,控制块190可以包括第一测量器192、第二测量器194、确定器195和显示器197。
第一测量器192可以将扭矩传感器160的感测结果数字化。例如,第一测量器192可以接收在打开/关闭光掩模盒220时由扭矩传感器160测得的负荷以将该负荷数字化。
第二测量器194可以将位移传感器155的感测结果数字化。例如,第二测量器可以测量位移传感器155的突出销155a的长度以将测得的突出销1 55a的长度数字化。
确定器195可以接收第一测量器192和第二测量器194的测量结果,以确定光掩模盒220的平整度。例如,确定器194可以包括存储器,其用于储存用来打开/关闭正常光掩模盒220的关于参考旋转角度的负荷(在下文中,称为参考负荷)、以及位移传感器155的突出销155a的长度(在下文中,称为参考长度)。确定器194可以将第一测量器192的测量结果与存储器中的参考负荷进行比较,并将第二测量器194的测量结果与存储器中的参考长度进行比较,以确定光掩模盒220的平整度。
显示器197可以显示确定器195的确定结果。此外,显示器197可以另外显示第一测量器192和第二测量器194的测量结果。
图9和图10是示出根据示例实施例的检测光掩模盒的更换定时的方法的流程图。
参考图9,在步骤S1中,可以清洁在曝光设备200中使用的光掩模盒220。在步骤S2中,可以将已清洁的光掩模盒220装载到检查设备100的装载端口120中。
在步骤S3中,可以在检查设备100的检查块110中测量光掩模盒220的故障。
特别地,参考图10,在步骤S31中,支撑轴C可以通过电力供应器158而向上移动,以将光掩模盒220的底座221放置在支撑板152上。
在步骤S32中,位移传感器155可以与光掩模盒220的底座221接触。位移传感器155可以测量每个位移传感器155的突出销155a的长度。
同时,在步骤S33中,打开/关闭销153可以与光掩模盒220的底座221接触。支撑轴C可以通过动力供应器158来旋转以使与打开/关闭销153接触的底座21旋转。因此,盖225可以与底座21分开。连接至支撑轴C的扭矩传感器160可以根据用于使底座与盖225分开的支撑轴C的旋转角度来测量负荷。
在步骤S34中,控制块190的确定器195可以将位移传感器155的测得的值与正常光掩模盒220的突出销155a的参考长度进行比较。此外,控制块190的确定器195可以将扭矩传感器160的测得的值与用于打开/关闭正常光掩模盒220的参考负荷进行比较。
当确定器195的比较结果在可允许的误差范围内时,在步骤S35中,确定器195可以将光掩模盒220确定为是正常的。相反,当确定器195的比较结果能超出可允许的误差范围时,在步骤S36中,确定器195可以将光掩模盒确定为是异常的。然后,可以将分开的光掩模盒220组装成原始形状。
当在步骤S35中确定光掩模盒220是正常的时,在步骤S4中,可以将光掩模盒220传送到储存块210。
相反,当在步骤S36中确定光掩模盒220是异常的时,在步骤S5中,可以另外检查光掩模盒220。用于另外检查光掩模盒220的步骤可以包括:最后检查是否由于不是由光掩模盒220引起的组装故障、位移传感器155和扭矩传感器160的故障等而确定光掩模盒220是异常的。当由于组装故障、位移传感器155和扭矩传感器160的故障等而确定光掩模盒220是异常的时,在步骤S4中可以将光掩模盒220传送到储存块210。
当由于光掩模盒220的故障而将光掩模盒220确定为异常的时,在步骤S6中,然后可以丢弃光掩模盒220。
根据示例实施例,可以周期性地测量和监视光掩模盒220的平整度,以实时确定光掩模盒220的更换定时。
在示例实施例中,位移传感器155可以位于支撑板152上方。可替代地,位移传感器156可以被安装在光掩模盒220的盖224的导向件g上。在导向件g处的位移传感器156可以包括以均匀的间隙彼此间隔开的两个对应的传感器。
本发明的上述实施例旨在说明而不是限制本发明。各种替代方案和等效方案是可能的。本发明不受本文中描述的实施例的限制。本发明也不限于任何特定类型的半导体器件。鉴于本公开,另外的增加、减少或修改是显而易见的,并且意图落入所附权利要求的范围内。
