本申请的较佳实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地说明,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
实施例1
请参考图1,本发明提出了一种基板处理装置。基板处理装置包括:夹持机构200、旋转驱动机构300、加热机构400、喷头机构500、温度监测机构及控制机构800。
夹持机构200用于在工艺过程中夹持基板100并将基板100保持为水平状态。夹持机构200还包括支撑部202和多个定位销201,多个定位销201设置于支撑部202边缘上。在工艺过程中,夹持机构200夹持基板100时,通过多个定位销201对基板100实现夹持固定,进而将基板100保持在水平状态。
旋转驱动机构300用于驱动支撑部202旋转,旋转驱动机构300包括传动机构301和驱动机构302。示例性的,本实施例中,传动机构301为传动轴,驱动机构302在实际使用的过程中可以根据实际作业要求选择。示例性的,本实施例选择步进电机作为驱动机构302。工艺过程中,旋转驱动机构300通过驱动支撑部202使基板100以穿过基板100中心的铅垂线为轴进行旋转。
加热机构400设置于支撑部202与基板100之间。请结合图1及参照图2a和图2b,图2a示出了根据本发明实施例的加热机构俯视结构示意图;图2b示出了根据本发明实施例的加热机构仰视结构示意图。加热机构400包括一安装板401和多个加热元件402,多个加热元件402可以分成数个加热元件组4021。安装板401被配置为承载多个加热元件402。加热元件402被配置为在工艺过程中加热基板100。值得注意的是,为了提高效率、便于安装,在实际安装过程中,多个加热元件402首先集成于一电路板4023上,然后安装于安装板401上。安装板401的底部固定连接有支撑轴405的一端,支撑轴405的另一端穿过传动机构301到达传动机构301外部并进行固定。在工艺过程中,夹持机构200带动基板100旋转,而加热机构400不做旋转运动。更进一步地,基板100与加热机构400之间设置一个加热元件发射的光能穿透的板700,示例性的,板700由蓝宝石或石英制成。当板700定位在夹持机构200上时,在工艺过程中,板700被配置成与夹持机构200一起旋转。
示例性的,本发明实施例中,加热元件402为LED灯珠,多个LED灯珠设置在以安装板401的中心为圆心的多个同心圆的圆周上,对多个加热元件402进行分组,分成多个加热元件组4021。更进一步地,每个加热元件组4021围成的圆的圆心与夹持机构200的中心对齐,也与夹持机构200夹持的基板100的中心对齐。为了能够达到基板100局部区域温度独立调控的目的,本发明中每个加热元件组4021的加热温度能够被独立控制,通过独立控制每组LED灯珠的加热功率达到改变加热温度进而调控基板100局部区域温度的目的。本发明实施例中,LED灯珠所发出的光的波长范围为[200,380)nm或(650,2500]nm。
请继续参照图1,喷头机构500包括液体喷头501和摆臂502,液体喷头501设置在摆臂502上。工艺过程中,液体喷头501被配置为将液体分配至置于夹持机构200上的基板100表面;摆臂502上配置有向液体喷头501供液的液体输送管路,且摆臂502可以带动液体喷头501沿基板100的径向方向在基板100中心至基板100边缘之间往复移动。
温度监测机构包括第一温度监测单元601,第一温度监测单元601被配置为在液体喷头501沿基板100的径向方向由基板100中心向基板100边缘移动并向基板100表面连续喷液的过程中,当液体喷头501移动至基板100上方的某一区域时,监测该某一区域所对应的基板100表面区域内所形成液膜的温度,并将温度发送至控制机构800。示例性的,第一温度监测单元601为温度传感器。第一温度监测单元601可以被设置在任何能够监测到基板100表面所形成液膜温度的位置,在本实施例中,选择将第一温度监测单元601设置于摆臂502上。
控制机构800被配置为接收温度,并基于温度调控加热机构400对基板100对应区域的加热温度。
具体地,在液体喷头501沿基板100的径向方向由基板100中心向基板100边缘移动并向基板100表面连续喷液的过程中,当液体喷头501移动至基板100上方的某一区域时,控制位于该某一区域对应安装板401半径上的加热元件组4021至第二功率,达到第二功率的加热元件组4021对基板100对应区域进行加热至第二温度。第二温度为预设值,第二温度约为使液体喷头501向基板100分配的液体达到沸点的温度,在本实施例中,第二温度大于或等于液体沸点的温度,以IPA为例,较佳的第二温度工艺范围为78-85℃。
随着液体喷头501沿基板100的径向方向移动并连续向基板100表面分配液体,液体喷头501将液体分配到基板100表面一区域内并形成液膜时,第一温度监测单元601实时监测液膜的温度,并将温度反馈至控制机构800,控制机构800对所接收到的温度进行判断,当判断结果为:基板100表面上形成的液膜温度低于预设的第二温度,控制机构800控制基板100表面液膜温度低于第二温度的区域所对应的加热元件组4021的加热功率变大达到第二功率,以迅速提高该区域的加热温度,使加热温度快速达到第二温度。因为LED灯珠的工作功率可以瞬时改变,因此能够非常快速的对局部温度做出调整,一旦检测到某区域的液膜温度低于第二温度,控制机构800控制该某区域所对应的加热元件组4021所包含的LED灯珠的工作功率变大,几乎能够瞬时改变该区域的加热温度,以保证干燥效果。
值得注意的是,本发明中,加热元件组4021可以为某一半径上的加热元件,也可以为以某一半径为中心向远离安装板401中心延伸一定距离范围内的所有加热元件,也可以为以某一半径为中心分别向远离安装板401中心和靠近安装板401中心一定距离范围内的所有加热元件。具体地,每个加热元件组4021的覆盖范围选择可以根据实际情况进行适应性的调整及选择。应当理解的,本处的某一半径是指:液体喷头501在沿基板100的径向方向由基板100的中心向基板100的边缘移动的过程中,液体喷头501移动至基板100上方的某一区域,该区域所对应的安装板401的半径。
更进一步地,喷头机构500还包括一个氮气喷头,用于氮气吹扫。
更进一步地,在液体喷头501向基板100表面分配液体之前,控制机构800控制加热元件402整体的加热功率为第一功率,达到第一功率的加热元件402将基板100加热至第一温度。第一温度为预加热的温度,其作用为将基板100整体均匀加热。以IPA为例,较佳的第一温度工艺范围为60-70℃。第一功率是指能够将基板100加热至第一温度所需的LED灯珠的工作功率。通过预先将加热元件402的整体加热功率调整至第一功率,能够对基板100进行预加热,使基板100在被分配液体之前就能具有第一温度,当加热元件402需要调整局部区域的加热温度时,能够更快地达到第二温度,使干燥效率更高。第一温度小于第二温度。
本发明实施例通过设置第一温度监测单元601可以随着液体喷头501的移动,实时监测液体喷头501向基板100表面分配的液膜的温度并进行反馈,能够更加精准的监测液体喷头501所喷出的液体的温度;同时通过第一温度监测单元601监测的结果,控制机构800进行实时控制调整基板100表面液膜温度低于第二温度的区域所对应的加热元件组4021的加热功率,以便于快速、精确的调控第一温度监测单元601实时监测到的区域的加热温度,使干燥过程以及干燥结果更具有可控性。
值得注意的是,本发明的装置不仅适用于基板100于清洗工艺结束后对基板100进行的干燥处理,在刻蚀工艺中也可以使用。当本装置在湿法刻蚀工艺中使用时,通过喷头机构将蚀刻化学液或配方药液输送到旋转的基板表面,对基板表面薄膜进行部分腐蚀或完全去除。
湿法刻蚀工艺,一般通过喷头机构将蚀刻化学液或配方药液输送到旋转的基板表面,对基板表面薄膜进行部分腐蚀或完全去除。因为温度是影响腐蚀速率和均匀性的重要参数之一,通过本申请的装置以及上述的处理方法可以实现分区动态精确控制基板和其表面液体的温度,进而获得良好的蚀刻速率和均匀性控制,提高集成电路湿法刻蚀工艺加工精度和稳定性。
本发明的实施例还提供了一种基板处理方法,包括:将基板夹持在夹持机构上;驱动夹持机构带动基板旋转;加热机构对基板进行加热;通过喷头机构的液体喷头向基板表面分配液体,在液体喷头沿基板的径向方向由基板中心向基板边缘移动并向基板表面连续喷液的过程中,当液体喷头移动至基板上方的某一区域时,温度监测机构监测该某一区域所对应的基板表面区域内所形成液膜的温度,并基于温度调控加热机构对某一区域所对应的基板表面区域的加热温度。
示例性的,工艺过程中,夹持机构200夹持基板100,保持基板100水平设置,喷头机构500位于基板100的上方。在本实施例中,喷头机构500的液体喷头501向基板100分配的液体为干燥液体IPA。在液体喷头501移动到基板100中心的正上方,向基板100表面分配液体之前,控制机构800控制加热机构400的加热元件402整体的工作功率为第一功率,处于第一功率的加热元件402对基板100整体进行加热至第一温度,示例性地,第一温度为70℃。
当基板100被均匀加热至第一温度之后,液体喷头501开始沿基板100的径向方向由基板100的中心向基板100的边缘移动,并向基板100分配干燥液体IPA,在该过程中,当液体喷头501移动至基板100上方的某一区域时,控制机构800控制位于该某一区域对应安装板401的半径上的加热元件组4021的工作功率由第一功率升至第二功率,达到第二功率的加热元件组4021对该某一区域所对应的基板100区域迅速加热至第二温度,示例性地,第二温度为80℃。
应当理解的,本装置同样适配基板的背面清洗工艺。当本装置应用于背面清洗工艺时,背面清洗喷嘴要求穿过加热机构400及板700的中心到达基板100的下方,以便于清洗液能够喷向基板100的下表面实施背面清洗工艺。
实施例2
本实施例提供了一种基板处理装置,该装置的结构与实施例1中的基板处理装置的结构基本相同,不同的是,如图3所示,位于安装板401边缘区域的边缘加热元件4022呈倾斜设置,倾斜设置的加热元件用于使安装板边缘区域被覆盖在倾斜设置的加热元件的加热区域中。
在实际工艺过程中,发明人发现在基板100边缘区域经常出现图案结构倒塌的现象,经分析发现,原因在于位于安装板401边缘区域的边缘加热元件4022所发出的光不能覆盖到基板100的边缘区域,导致在对基板100进行加热干燥的过程中,基板100边缘温度达不到目标温度,影响工艺效果,导致位于基板100边缘区域的图案结构倒塌,出现废片。为此,将位于安装板401边缘区域的边缘加热元件4022呈倾斜设置,在一个实施例中,边缘加热元件4022的倾斜角度为0.1°-60°。更进一步地,边缘加热元件4022的倾斜角度设置为5°-40°。倾斜一定角度设置的边缘加热元件4022能够确保边缘加热元件4022的目标区域对准基板100的边缘区域,以保证在加热干燥的过程中,基板100的边缘能够正常加热,进而防止基板100边缘区域的图案结构倒塌,确保干燥效果。
应当理解的,安装板401的边缘区域为安装板401边缘向安装板401中心指定距离的圆周与安装板401边缘之间的区域。示例性的,指定距离为0-1.5mm。在指定距离内可以设置一组边缘加热元件4022,也可以设置超过一组边缘加热元件4022,具体的设置情况可以根据实际工艺要求进行设置。
本实施例的其余结构与实施例1相同。
实施例3
本实施例提供了一种基板处理装置,该装置的结构与实施例1中的基板处理装置的结构基本相同,不同的是,请参照图4,该装置的温度监测机构还包括第二温度监测单元602。在实际安装过程中,第二温度监测单元602可以被设置在任何能够监测到基板100表面各区域的温度的位置,应当理解的,第二温度监测单元602与第一温度监测单元601可以选择组合设置在单个元件中,也可以选择将他们分开设置。在本实施例中,如图5所示,选择将第二温度监测单元602设置于摆臂502上,且与第一温度监测单元601分开设置。
请参考图5,在液体喷头501沿基板100的径向方向由基板100中心向基板100边缘移动并向基板100表面连续喷液的过程中,当液体喷头501离开基板上方的一区域N,向远离所述基板中心的方向上的下一区域N+1移动时,第二温度监测单元602被配置为监测该一区域N对应的基板表面区域的温度,并储存所监测的温度结果。利用第二温度监测单元602实时监测基板干燥完成的即时温度并进行统计,能够辅助监控基板处理装置的工艺安全。当基板在基板处理装置上完成对应工艺之后,从基板处理装置中取出基板进行工艺结果的检查,一旦发现基板某一区域的图案结构倒塌,此时可以根据第二温度监测单元602所记录的数据进行复盘检查。理想状态下,相邻半径上的加热元件在对基板进行加热时,目标加热温度是相同的,在基板表面的液膜被干燥完成时的基板表面温度也应该是几乎一致的,从第二温度监测单元602所监测的结果来看,数据应该是几乎相等的,如果在第二温度监测单元602所记录的数据内发现基板表面相邻区域的温度数据偏差较大,则表明该区域的加热元件产生了问题,在进行检修中目标便较为明确,能够提高机台检修的工作效率,同时保障基板加工良率。
本实施例的其余结构与实施例1相同。
实施例4
本实施例提供了一种基板处理装置,该装置的结构与实施例1中的基板处理装置的结构基本相同,不同的是,该装置的温度监测机构还包括第三温度监测单元。第三温度监测单元被配置为监测加热机构背面各处的实时温度,并将实时温度传输至控制机构800。
具体地,请参照图6,第三温度监测单元603包括多组温度传感器6031,多组温度传感器6031分别设置于加热元件402下方,且每组温度传感器6031与每个加热元件组4021对应设置。此时,第三温度监测单元603被配置为监测不同加热元件组4021的实时温度,并将实时温度传输至控制机构800,与此同时,控制机构800实时接收第三温度监测单元603的实时温度,当实时温度的数值大于预设值时,控制机构800发出警报信息。其中,预设值为加热元件正常工艺的温度,示例性的,预设值为80℃,当第三温度监测单元603监测到某加热元件组的工作温度大于80℃时,此时控制机构800接收到第三温度监测单元603监测到的温度之后,判定该加热元件组处于非正常的工作状态,需要及时检修,将发送警报信息,通知工作人员及时进行检修。
本实施例的其余结构与实施例1相同。
实施例5
本实施例提供了一种基板处理装置,该装置的结构与实施例1中的基板处理装置的结构基本相同,不同的是,如图7所示,基板处理装置还包括冷却机构,冷却机构包括设置于安装板401上的冷却部,冷却部位于加热元件402的下方,在工艺过程中,冷却部被配置为降低加热元件402的温度。冷却部的实际选择包括但不限于:冷却槽。具体的种类可以根据实际的工艺需求进行选择。冷却部被配置为降低加热元件402的温度,从而避免当工艺过程中加热元件402的温度过高导致加热元件402的损坏。
具体地,请继续参照图7,冷却部为冷却槽404时,冷却槽404开设于安装板401的上端面。安装板401与加热元件402进行安装时,承载多个加热元件402的电路板4023与安装板401卡合固定,形成密封空间,安装板401底部开设有进液口9和出液口4042。当对加热元件402进行冷却时,外部冷却液经过进液口4041进入冷却槽,灌满整个冷却槽404使冷却液的液面直接与加热元件402相接触,以对加热元件402进行降温,同时,冷却液从出液口4042不断排出,形成动态平衡的过程,在动态平衡的过程中,冷却槽404内始终保持充满冷却液的状态,以持续对加热元件402进行降温处理。
请参照图8,为了更进一步地保障密封效果,安装板401与电路板4023固定处设置一密封圈403以进行密封,使密封效果更佳。
在另一个实施例中,为了进一步保障冷却的均匀性,冷却部的冷却槽404数量为若干个,请参照图9,每个冷却槽404都大致为圆环形,每一个冷却槽404均设置一个进液口4041和一个出液口4042。更进一步的,每个加热元件组4021下方对应设置一个冷却槽404,以达到精准降温、均匀降温的目的。
实施例6
