Description

减少工艺腔室内基板滑动的设备及方法
技术领域
本揭示案的实施方式大体涉及基板处理系统,且更特定而言,涉及用于处理具有背侧氧化物层的基板的设备及方法。
背景技术
在处理诸如半导体晶片之类的基板时,基板放置于基板处理系统的工艺腔室中的基板支撑件上。用于支撑基板的经常为支撑构件,例如加热器基座,用以在实行工艺期间将基板保持在适合的位置。通常,基板放置于支撑构件上且相对于支撑构件大致上位于中心,以使基板被均匀地处理。然后在基板上执行一或更多个工艺,例如等离子体工艺或其他工艺。在完成所述一或更多个工艺之后,然后举例而言,使用升降销(lift pin),将基板从基板支撑件移除,升降销可在与基板支撑件的平面呈垂直的方向中移位。升降销相对于基板移动,以将基板举起远离基板支撑件,用以随后将基板从工艺腔室移除。
本发明人已观察到,在一些工艺中,当在工艺完成之后尝试将基板举起时,基板可能不希望地在基板支撑件上移动。具体而言,本发明人已观察到,一旦在一些工艺完成之后尝试将基板举起时基板可能不希望地移动,这些工艺是在具有厚背侧氧化物层(例如约或更大的厚度)的基板上执行,所述厚背侧氧化物层设置于基板支撑件上且所述背侧氧化物层接触所述基板支撑件。
因此,本发明人已提供用于在工艺腔室中处理基板的改善的方法及设备的实施方式。
发明内容
本文揭示用于处理基板的方法及设备。在一些实施方式中,用于处理基板的设备包含:基板支撑件,所述基板支撑件具有基板支撑表面,所述基板支撑表面包含电绝缘涂层;基板升降机构,所述基板升降机构包含多个升降销,所述多个升降销被配置为在第一位置与第二位置之间移动,所述第一位置设置于基板支撑表面下方,第二位置设置于基板支撑表面上方;及连接件,所述连接件被配置为在所述多个升降销抵达基板支撑表面的平面之前选择性地提供基板支撑件与基板升降机构之间的电气连接。
在一些实施方式中,用于处理基板的设备包含:基板支撑件,当在基板的第二表面上执行工艺时,基板支撑件支撑且接触基板的第一表面的至少一部分,当执行工艺时基板支撑件为电气隔离的;基板升降机构,当执行工艺时基板升降机构与基板分隔且随后基板升降机构接触基板的第一表面;及连接件,在工艺结束之后但在基板升降机构接触基板的第一表面之前的时间点,所述连接件提供基板支撑件与基板升降机构之间的电气连接,使得基板的第一表面与基板升降机构之间的电位差被移除。
在一些实施方式中,用于处理基板的设备包含:工艺腔室;设置于工艺腔室内的基板支撑件,所述基板支撑件具有基板支撑表面,所述基板支撑表面包含电绝缘涂层;基板升降机构,所述基板升降机构包含多个升降销,所述多个升降销被配置为在第一位置与第二位置之间移动,所述第一位置设置于基板支撑表面下方,所述第二位置设置于基板支撑表面上方;连接件,所述连接件被配置为在所述多个升降销抵达基板支撑表面的平面之前选择性地提供基板支撑件与基板升降机构之间的电气连接;及等离子体功率源,用以在工艺腔室内产生等离子体。
在一些实施方式中,用于处理基板的设备包含:连接件,在基板的第二表面上执行的工艺结束之后的时间点,所述连接件提供基板升降机构与基板的第一表面之间的电气连接,其中当执行工艺时基板的第一表面的至少一部分由基板支撑件支撑且接触基板支撑件,当执行工艺时基板支撑件为电气隔离的,及当执行工艺时基板升降机构与基板分隔。
在一些实施方式中,处理基板的方法包含以下步骤:在设置于基板支撑件上的基板上实行工艺,其中当实行工艺时基板支撑件为电气隔离的;在工艺结束之后,电气耦合基板支撑件与基板升降机构,以降低或移除基板支撑件与基板升降机构之间的电位差;及接着使基板接触基板升降机构。
以下描述本揭示案的其他及进一步的实施方式。

具体实施方式
本揭示案的实施方式涉及有利地避免基板在基板支撑件上由于在完成处理之后基板升降机构与基板之间的电压差而移动的方法及设备。虽然并非限制本揭示案的范围,本揭示案的实施方式有益于在工艺腔室中的工艺(举例而言,等离子体工艺)完成之后解决基板偏移的问题,基板例如为具有厚背侧氧化物层(举例而言,具有约或更厚的厚度的背侧氧化物)的半导体晶片。
本发明人已观察到位于基板支撑件中心的基板在整个工艺中及在工艺刚完成时可维持于中心处。本发明人已进一步观察到在等离子体工艺完成之后当升降销接触基板时基板有时不希望地横向偏移,但在非等离子体工艺完成之后当由升降销碰触时基板则不偏移。本发明人亦观察到当薄背侧氧化物晶片经等离子体处理后则所述偏移不发生。本发明人因此作以下结论,基板的厚背侧氧化物层、等离子体工艺及与升降销接触的组合导致基板的位置偏移。
更具体而言,本发明人相信,直流(DC)等离子体的自偏压(self-bias)提供电场,当在等离子体工艺期间施加至基板时,所述电场造成厚背侧氧化物层的电介质极化。亦即,正电荷在厚背侧氧化物层内以朝向电场的方向移位,且负电荷在厚背侧氧化物层内以与电场相反的方向移位。在等离子体工艺结束时厚背侧氧化物层保持极化,因为接触基板的基板支撑件的表面被电绝缘涂层涂布,例如类金刚石碳(diamond-like carbon;DLC)涂层或类似者。这些涂层可用以避免基板与基板支撑件之间的热不匹配且降低基板中的应力。本发明人注意到,电绝缘涂层阻止在厚背侧氧化物层中累积的电荷经由基板支撑件散逸。虽然在升降销接触基板之前在厚背侧氧化物层中累积的电荷可理论上通过等待而经由基板中的微裂缝散逸,但所浪费的时间远大于制造处理所期望的时间。
由于电荷累积,在完成工艺之后电位差维持跨越厚背侧氧化物层,当基板被升降销接触时,所述电位差导致基板静电排斥且自中心位置滑开。
在一些实施方式中,上述问题可通过从基板支撑件的基板支撑表面移除电绝缘涂层来解决。举例而言,基板支撑件的基板支撑表面可由涂层涂布,例如以如上所述避免基板与基板支撑件之间的热不匹配,而涂层从基板支撑表面被移除。通过从基板支撑表面移除电绝缘涂层,基板直接接触基板支撑件,基板支撑件为导体;使得任何累积在厚背侧氧化物层的表面上的电荷散逸。作为另一个实例,基板支撑件的基板支撑表面可由上述涂层及钛涂层两者涂布,且这些涂层皆从基板支撑件的基板支撑表面移除,此举进一步降低厚背侧氧化物层的表面上的电荷累积。
本发明人确定,在设置于移除了电绝缘涂层的基板支撑表面上的基板上实行等离子体工艺后,当基板接触升降销时,基板的滑动显著降低。本发明人进一步确定,对于例如半导体晶片,从基板支撑件移除电绝缘涂层并未有害地显著影响执行工艺之后的基板应力。
通过在基板上完成工艺之后但在升降销接触基板之前的时间点以使基板支撑件与升降销的电位相等且因此使厚背侧氧化物层与升降销的电位相等的方式并入连接件,例如接地回圈(grounding loop),本发明人进一步解决工艺后基板滑动的问题。通过移除电位差,进一步降低基板接触升降销时基板的滑动。
图1绘示根据本揭示案的一些实施方式的基板支撑件的非限制实例100。基板支撑件102具有基板支撑表面104。在一些实施方式中,基板支撑件还可包含加热器110,例如电阻式加热器。在一些实施方式中,具有电绝缘涂层(例如上述的涂层)的现有基板支撑件可被移除电绝缘涂层。基板120可具有介电背侧涂层,例如厚(举例而言,大于约)背侧氧化物层122,背侧氧化物层122与基板支撑件102的基板支撑表面104接触。
举例而言,基板升降机构105包含多个升降销106,这些升降销中的每一个于各自升降销的基底处皆附接至箍环(hoop ring)108。基板支撑件具有多个对应的开口103,升降销106可进入开口103中。基板升降机构105可在第一位置与第二位置之间移动,第一位置为当基板120设置于基板支撑件102上时远离基板支撑件102及基板120而设置,第二位置为与基板120的第一表面接触以和基板支撑件102分隔开的关系来支撑基板120(举例而言,促使将基板传送至基板传送机器人或从基板传送机器人传送基板)。
连接件例如接地条(grounding strip)130举例而言电气耦接于基板支撑件102的底部处,且通过基板支撑件102与基板升降机构105的相对移动,在基板升降机构105接触基板120的第二表面之前使接地条130与基板升降机构105的顶表面(举例而言,箍环108)电气接触。在另一个实例中,连接件电气耦接于基板升降机构105的顶表面(举例而言,箍环108的顶表面)处,且通过基板支撑件与基板升降机构的相对移动,使连接件与基板支撑件的底表面电气接触。通过提供基板支撑件与基板升降机构之间的电气连接,连接件降低或移除基板支撑件与基板升降机构之间的任何电位差,当基板升降机构接触基板的第二表面时,此举最小化基板从基板支撑件的中心的任何滑动。
在一些实施方式中,接地条130可为柔性构件,例如薄材料箍或材料环(例如,接地回圈,举例而言,形成环的柔性金属带)。柔性接地条130可例如通过弹性变形而移动,以促进当移动基板升降机构105的升降销以接触基板及从基板支撑件102的基板支撑表面移除基板时基板支撑件102与基板升降机构105相对于彼此的持续移动。
图2A及图2B图示根据本揭示案的一些实施方式的具有基板支撑件202的工艺腔室200的非限制实例。虽然以下所述的基板支撑件202是用于物理气相沉积(PVD)工艺腔室中,但基板支撑件202可有利地用于其中等离子体处理或其他条件造成基板与基板支撑件的升降销之间的电位差的其他工艺腔室中。
基板支撑件202设置于工艺腔室200的处理容积内且由导电材料形成。连接件,例如接地条230,举例而言电气耦接于基板支撑件202的底部处。基板升降机构举例而言包含升降销206,升降销206中的每一个在各自的升降销的基底处附接至箍环208。除了以下所论述的细节之外,基板支撑件202、接地条230及基板升降机构中之一或更多可与以上结合图1所述的基板支撑件102、接地条130及基板升降机构105相似。
基板支撑件202及基板升降机构各自含于腔室壁204内且位于盖组件210下方。盖组件210可包含靶材,所述靶材的材料待溅射沉积于设置在基板支撑件202上的基板上。在一些实施方式中,等离子体功率源,例如直流(DC)电源212提供功率以在工艺腔室内由经由气源(未图示)而供应至腔室的一或更多种气体产生等离子体。在一些实施方式中,等离子体功率源通过盖组件210耦接至靶材。磁体214用以将等离子体约束于靠近靶材处,以增强处理,例如靶材利用均匀性、溅射速率、靶材寿命及类似者。替代地或以组合方式,可使用射频(RF)电源取代DC电源212,或RF电源与DC电源212一起使用,来提供功率以产生等离子体。
图2A图示在基板220的第一表面上的工艺完成时的工艺腔室200,基板220例如半导体晶片,半导体晶片的第二表面设置于基板支撑件202的基板支撑表面顶上且接触基板支撑表面。基板220还包含,举例而言,厚背侧氧化物层222,作为实例,厚背侧氧化物层222具有至少的厚度。举例而言,所述工艺为等离子体工艺,例如物理气相沉积(PVD)工艺、化学气相沉积(CVD)工艺、反应性离子蚀刻(RIE)或其他蚀刻工艺、或其他等离子体工艺。
在基板220的第一表面上的工艺完成之后,基板支撑件和基板升降机构相对于彼此移动,例如通过基板支撑件向下平移或是基板升降机构向上平移,或是基板支撑件向下平移且基板升降机构向上平移两者。执行基板支撑件与基板升降机构的相对移动以将基板从基板支撑件传送至基板升降机构,使得基板可例如通过使用基板传送机器人而传送出工艺腔室。
图2B图示在使得连接件230与基板升降机构电气接触之后且在基板升降机构已接触基板之后图2A的工艺腔室200的实例。如图2B中所示,发现基板实质上维持在基板支撑件的中心处。
图3绘示根据本揭示案的一些实施方式的处理基板的方法300的实例。可在具有与图1或图2A-2B中描述的基板支撑件相似的基板支撑件的工艺腔室中执行方法300,或可在具有根据以上教示的基板支撑件的其他适合的工艺腔室中执行方法300。
方法300通常于302处开始,于302处当基板由基板支撑件支撑时在基板上执行工艺。当执行工艺时,基板支撑件为电气隔离的。接着,于304处,在工艺结束之后,基板支撑件与基板升降机构电气耦合,以降低或移除基板与基板升降机构之间的任何电位差。举例而言,基板支撑件或基板升降机构中的至少之一相对于基板支撑件或基板升降机构中的至少另一个移动,直到使电气耦接至基板支撑件或基板升降机构中之一的连接件与基板支撑件或基板升降机构中的另一个电气接触。然后,于306处,例如通过基板支撑件或基板升降机构中的所述至少之一的进一步相对移动,使基板与基板升降机构接触,来将基板从基板支撑件举离。
虽然前述内容是针对本揭示案的实施方式,但在不背离本揭示案的基本范围下,可设计本揭示案的其他及进一步的实施方式。
