具体实施方式
以下,基于附图对本发明的实施方式进行说明。图1是表示本发明的实施方式的气相成长装置1的框图,中央所示的气相成长装置1的主体由俯视图表示。本实施方式的气相成长装置1是所谓的CVD装置,具备一对反应炉11、11、设置有处理单晶硅晶圆等的晶圆WF的第1机器人121的晶圆移载室12、一对装载锁定室13、设置有处理晶圆WF的第2机器人141的工厂接口14、设置收纳着多张晶圆WF的晶圆收纳容器15(卡式盒)的装载端口。
工厂接口14是与载置晶圆收纳容器15的清洁室大气氛围相同的区域。在该工厂接口14设置有第2机器人141,前述第2机器人141将收纳于晶圆收纳容器15的处理前的晶圆WF取出来向装载锁定室13投入,另一方面,将向装载锁定室13搬运来的处理后的晶圆WF向晶圆收纳容器15收纳。第2机器人141被第2机器人控制器142控制,装配于机器人手的末端的第2叶片143沿预先学习的既定的轨迹移动。
在装载锁定室13和工厂接口14之间,设置有具有气密性的能够开闭的第1门131,在装载锁定室13和晶圆移载室12之间,同样设置有具有气密性的能够开闭的第2门132。并且,装载锁定室13在为非活性气体氛围的晶圆移载室12和为大气氛围的工厂接口14之间作为置换氛围气体的空间发挥功能。因此,设置有将装载锁定室13的内部真空排气的排气装置、向装载锁定室13供给非活性气体的供给装置。
例如,从晶圆收纳容器15将处理前的晶圆WF向晶圆移载室12搬运的情况下,关闭工厂接口14侧的第1门131,关闭晶圆移载室12侧的第2门132,在使装载锁定室13为非活性气体氛围的状态下,用第2机器人141取出晶圆收纳容器15的晶圆WF,打开工厂接口14侧的第1门131,将晶圆WF向装载锁定室13搬运。接着,关闭工厂接口14侧的第1门131,使该装载锁定室13再次为非活性气体氛围后,打开晶圆移载室12侧的第2门132,用第1机器人121将该晶圆WF向晶圆移载室12搬运。
反之,将处理后的晶圆WF从晶圆移载室12向晶圆收纳容器15搬运的情况下,关闭工厂接口14侧的第1门131,关闭晶圆移载室12侧的第2门132,在使装载锁定室13为非活性气体氛围的状态下,打开晶圆移载室12侧的第2门132,用第1机器人121将晶圆移载室12的晶圆WF向装载锁定室13搬运。接着,关闭晶圆移载室12侧的第2门132,再次使该装载锁定室13为非活性气体氛围后,打开工厂接口14侧的第1门131,用第2机器人141将该晶圆WF向晶圆收纳容器15搬运。
晶圆移载室12由密闭的腔构成,一方与装载锁定室13经由能够开闭的具有气密性的第2门132连接,另一方经由具有气密性的能够开闭的闸门阀114连接。在晶圆移载室12设置有第1机器人121,前述第1机器人121将处理前的晶圆WF从装载锁定室13向反应室111搬运,并且将处理后的晶圆WF从反应室111向装载锁定室13搬运。第1机器人121被第1机器人控制器122控制,装配于机器人手的末端的第1叶片123沿预先学习的动作轨迹移动。
总管气相成长装置1的整体的控制的总管控制器16、第1机器人控制器122、第2机器人控制器142相互接受发送控制信号。并且,来自总管控制器16的动作指令信号被向第1机器人控制器122传送时,第1机器人控制器122控制第1机器人121的动作,该第1机器人121的动作结果被从第1机器人控制器122向总管控制器16传送。由此,总管控制器16识别第1机器人121的动作状态。同样地,来自总管控制器16的动作指令信号被向第2机器人控制器142传送时,第2机器人控制器142控制第2机器人141的动作,该第2机器人141的动作结果被从第2机器人控制器142向总管控制器16传送。由此,总管控制器16识别第2机器人141的动作状态。
非活性气体从未图示的非活性气体供给装置向晶圆移载室12供给,晶圆移载室12的气体被与排气口连接的洗涤器(洗涤集尘装置)净化后向***外放出。这种洗涤器省略详细的图示,例如能够用以往公知的加压水式洗涤器。
反应炉11是用于通过CVD法在晶圆WF的表面生成外延膜的装置,具备反应室111,在该反应室111内设置有载置晶圆WF而旋转的基座112,此外在反应室111设置有供给氢气及用于生成CVD膜的原料气体(CVD膜为硅外延膜的情况下例如是四氯化硅SiCl 4、三氯硅烷SiHCl 3等)、掺杂剂气体的气体供给装置113。此外,虽省略图示,但在反应室111的周围设置有用于将晶圆WF升温至既定温度的加热灯。进而,在反应室111和晶圆移载室12之间设置有闸门阀114,通过关闭闸门阀114,确保反应室111和晶圆移载室12的气密性。这些反应炉11的基座112的驱动、气体供给装置113进行的气体的供给・停止、加热灯的开启/关闭、闸门阀114的开闭动作的各控制被来自总管控制器16的指令信号控制。另外,图1所示的气相成长装置1表示设置有一对反应炉11、11的例子,但也可以设置一个反应炉11,也可以是三个以上的反应炉。
在反应炉11也设置有具有与晶圆移载室12相同的结构的洗涤器(洗涤集尘装置)。即,从气体供给装置113供给的氢气或原料气体、掺杂剂气体被与设置于反应室111的排气口连接的洗涤器净化后,被向***外放出。关于该洗涤器,例如也能够使用以往公知的加压水式洗涤器。
本实施方式的气相成长装置1中,将晶圆WF用支承该晶圆WF的整周外边缘的环状的载具C在装载锁定室13和反应室111之间搬运。图2A是表示载具C的俯视图,图2B是包括晶圆WF及反应炉11的基座112的载具C的剖视图,图5是表示反应室111内的晶圆WF及载具C的移载流程的俯视图及剖视图。
本实施方式的载具C例如由SiC等材料构成,形成为环状,具有载置于图2B所示的基座112的上表面的底面C11、接触晶圆WF的背面的外边缘整周来支承的上表面C12、外周侧壁面C13、内周侧壁面C14。并且,支承于载具C的晶圆WF被搬入反应室111内的情况下,如图5(A)的俯视图所示,在第1机器人121的第1叶片123载置有载具C的状态下,如同图(B)所示地搬运至基座112的上部,如同图(C)所示地借助相对于基座112能够上下移动地设置的三个以上的载具升降销115暂时抬起载具C,如同图(D)所示地使第1叶片123后退后,如同图(E)所示地使基座112上升,由此将载具C载置于基座112的上表面。
反之,将在反应室111结束处理的晶圆WF以搭载于载具C的状态取出的情况下,从如图5(E)所示的状态,如同图(D)所示地使基座112下降,仅借助载具升降销115支承载具C,如同图(C)所示,使第1叶片123向载具C和基座112之间前进,之后如同图(B)所示地使三个载具升降销115下降,将第1叶片123载置于载具C,使第1机器人121的手动作。由此,能够将结束处理后的晶圆WF以搭载于载具C的状态取出。
此外,在本实施方式的气相成长装置1,为了将载具C在从装载锁定室13至反应室111的工序间搬运,在装载锁定室13,将处理前的晶圆WF载置于载具C,将处理后的晶圆WF从载具C取出。因此,在装载锁定室13,设置有将载具C在上下2层支承的架17。图3A是表示在装载锁定室13设置的架17的俯视图,图3B是包括晶圆WF的架17的剖视图。本实施方式的架17设置有被固定的架基部171、能够相对于该架基部171上下升降地设置的将两个载具C上下两层支承的第1架172及第2架173、能够相对于架基部171上下升降地设置的三个晶圆升降销174。
第1架172及第2架173(图3A的俯视图中,第2架173由于第1架172而隐藏,所以仅图示第1架172。)具有用于将载具C在4点支承的突起,在第1架172载置一个载具C,在第2架173也载置一个载具C。另外,在第2架173载置的载具C被***第1架172和第2架173之的间的间隙。
图4是表示装载锁定室13的晶圆WF及载具C的移载流程的俯视图及剖视图,如同图(B)所示地表示在第1架172支承有载具C的状态下在该载具C搭载处理前的晶圆WF的流程。即,设置于工厂接口14的第2机器人141将收纳于晶圆收纳容器15的一张晶圆WF载置于第2叶片143,经由装载锁定室13的第1门131,如同图(B)所示地搬运至架17的上部。接着,如同图(C)所示,相对于架基部171使三个晶圆升降销174上升,暂时抬起晶圆WF,如同图(D)所示地使第2叶片143后退。另外,三个晶圆升降销174如同图(A)的俯视图所示,设置于不与第2叶片143干涉的位置。接着,如同图(D)及(E)所示,使三个晶圆升降销174下降且使第1架172及第2架173上升,由此在载具C搭载晶圆WF。
反之,将载置于载具C的状态下向装载锁定室13搬运来的处理后的晶圆WF向晶圆收纳容器15搬运的情况下,从图4(E)所示的状态,如同图(D)所示地使三个晶圆升降销174上升且使第1架172及第2架173下降,仅借助晶圆升降销174支承晶圆WF,如同图(C)所示地使第2叶片143向载具C和晶圆WF之间前进后,如同图(B)所示地使三个晶圆升降销174下降,将晶圆WF载置于第2叶片143,使第2机器人141的手动作。由此,能够将结束处理的晶圆WF从载具C向晶圆收纳容器15取出。另外,图4(E)所示的状态下结束处理的晶圆WF在搭载于载具C的搭载的状态下被向第1架172搬运,但被向第2架173搬运的情况也能够以同样的流程,将晶圆WF从载具C向晶圆收纳容器15取出。
图6(A)是表示在第1机器人121的手的末端装配的第1叶片123的一例的俯视图,图6(B)是包括载具C及晶圆WF的第1叶片123的剖视图。本实施方式的第1叶片123在短边板状的主体的一面形成有与载具C的外周侧壁面C13对应的直径的第1凹部124。第1凹部124的直径形成为比载具C的外周侧壁面C13的直径稍大。并且,第1机器人121在搬运载有晶圆WF的或空的载具C的情况下,将载具C载置于第1凹部124。
接着,说明将本实施方式的气相成长装置1的、外延膜的生成前(以下也仅称作处理前)及外延膜的生成后(以下也仅称作处理后)的晶圆WF、载具C处置的流程。图7~图10是表示本实施方式的气相成长装置的晶圆及载具C的处置流程的示意图,与图1的一侧的晶圆收纳容器15、装载锁定室13及反应炉11对应,在晶圆收纳容器15收纳多张晶圆W1,W2,W3…(例如合计25张),以该顺序开始处理。
图7的工序S0表示从此用气相成长装置1开始处理的等待状态,在晶圆收纳容器15收纳多张晶圆W1,W2,W3…(例如合计25张),在装载锁定室13的第1架172支承空的载具C1,在第2架173支承空的载具C2,装载锁定室13呈非活性气体氛围。
下一工序S1中,第2机器人141将收纳于晶圆收纳容器15的晶圆W1载置于第2叶片143,打开装载锁定室13的第1门131向支承于第1架172的载具C1移载。该移载的流程如参照图4所作说明。
下一工序S2中,关闭装载锁定室13的第1门131也关闭第2门132的状态下,将装载锁定室13的内部再次置换成非活性气体氛围。然后,打开第2门132,在第1机器人121的第1叶片123载置载具C1,打开反应炉11的闸门阀114,经由该闸门阀114将搭载有晶圆W1的载具C1向基座112移载。该移载的流程如参照图4所作说明。工序S2~S4中,反应炉11中进行相对于晶圆W1的CVD膜的生成处理。
即,将搭载着处理前的晶圆W1的载具C1向反应室111的基座112移载,关闭闸门阀114,待机既定时间后,借助气体供给装置113向反应室111供给氢气,使反应室111为氢气氛围。接着,借助加热灯使反应室111的晶圆W1升温至既定温度,根据需要实施蚀刻、热处理等的前处理后,借助气体供给装置113将原料气体、掺杂剂气体在控制流量及/或供给时间的同时供给。由此,在晶圆W1的表面生成CVD膜。形成CVD膜后,借助气体供给装置113向反应室111再次供给氢气来将反应室111置换成氢气氛围后,待机既定时间。
这样在工序S2~S4中,借助反应炉11对晶圆W1进行处理的期间,第2机器人141从晶圆收纳容器15取出下一晶圆W2,准备下一处理。在此之前,在本实施方式中,工序S3中,关闭装载锁定室13的第2门132也关闭第1门131的状态下,将装载锁定室13的内部置换成非活性气体氛围。并且,打开第2门132,借助第1机器人121,将支承于第2架173的载具C2移载至第1架172,关闭第2门132。接着,在工序S4中,第2机器人141将收纳于晶圆收纳容器15的晶圆W2载置于第2叶片143,打开第1门131,向支承于装载锁定室13的第1架172的载具C2移载。
这样在本实施方式中,追加工序S3,收纳于晶圆收纳容器15的处理前的晶圆WF搭载于作为装载锁定室13的架17的最上层的架的第1架172。这是由于以下的理由。即,如工序S2所示,搭载下一晶圆W2的空的载具C2支承于第2架173的情况下,在其上搭载晶圆W2时,有搭载有处理后的晶圆W1的载具C1被向第1架172移载的可能性。本实施方式的气相成长装置1的载具C被搬运至反应室111,所以载具C成为颗粒的发生要因,在处理前的晶圆W2的上部支承载具C1时,有尘埃落下至处理前的晶圆W2的可能。因此,追加工序S3,将空的载具C2向第1架172移载,使得处理前的晶圆WF搭载于装载锁定室13的架17的最上层的架(第1架172)。
工序S5中,关闭装载锁定室13的第1门131也关闭第2门132的状态下,将装载锁定室13的内部置换成非活性气体氛围。然后,打开反应炉11的闸门阀114,将第1机器人121的第1叶片123***反应室111,移载搭载有处理后的晶圆W1的载具C1,从反应室111取出,关闭闸门阀114后,打开第2门132,向装载锁定室13的第2架173移载。接着,向第1机器人121的第1叶片123载置支承于第1架172的载具C2,将搭载有该处理前的晶圆W2的载具C2如工序S6所示,经由晶圆移载室12,打开闸门阀114来向反应炉11的基座112移载。
工序S6~S9中,在反应炉11,进行相对于晶圆W2的CVD膜的生成处理。即,将搭载有处理前的晶圆W2的载具C2向反应室111的基座112移载,关闭闸门阀114,待机既定时间后,借助气体供给装置113向反应室111供给氢气,使反应室111为氢气氛围。接着,借助加热灯使反应室111的晶圆W2升温至既定温度,根据需要实施蚀刻、热处理等的前处理后,借助气体供给装置113将原料气体、掺杂剂气体在控制流量及/或供给时间的同时供给。由此,在晶圆W2的表面生成CVD膜。形成CVD膜后,借助气体供给装置113再次向反应室111供给氢气,将反应室111置换成氢气氛围后,待机既定时间。
这样工序S6~S9中,借助反应炉11对晶圆W2进行处理的期间,第2机器人141将处理后的晶圆W1收纳于晶圆收纳容器15,并且从晶圆收纳容器15取出下一晶圆W3,准备下一处理。即,工序S7中,关闭装载锁定室13的第2门132也关闭第1门131的状态下,将装载锁定室13的内部置换成非活性气体氛围。然后,打开第1门131,借助第2机器人141,将处理后的晶圆W1从支承于第2架173的载具C1载置于第2叶片143,如工序S8所示地将该处理后的晶圆W1收纳于晶圆收纳容器15。接着,与上述的工序S3同样地,在工序S8中,在关闭装载锁定室13的第1门131也关闭第2门132的状态下,将装载锁定室13的内部置换成非活性气体氛围。然后,打开第2门132,借助第1机器人121,将支承于第2架173的载具C1向第1架172移载。
接着,在工序S9中,在关闭装载锁定室13的第2门132也关闭第1门131的状态下,将装载锁定室13的内部置换成非活性气体氛围。然后,借助第2机器人141,将收纳于晶圆收纳容器15的晶圆W3载置于第2叶片143,如工序S9所示,打开第1门131,向在装载锁定室13的第1架172支承的载具C1移载。
工序S10中,与上述的工序S5同样地,关闭装载锁定室13的第1门131也关闭第2门132的状态下,将装载锁定室13的内部置换成非活性气体氛围。并且,打开反应炉11的闸门阀114,将第1机器人121的第1叶片123***反应室111,载置搭载有处理后的晶圆W2的载具C2,关闭闸门阀114后,打开第2门132,从反应室111向装载锁定室13的第2架173移载。接着,在第1机器人121的第1叶片123载置支承于第1架172的载具C1,将搭载有该处理前的晶圆W3的载具C1如工序S11所示,经由晶圆移载室12向反应炉11的基座112移载。
工序S10中,与上述的工序S7同样地,关闭装载锁定室13的第2门132也关闭第1门131的状态下,将装载锁定室13的内部置换成非活性气体氛围。并且,打开第1门131,借助第2机器人141,将处理后的晶圆W2从支承于第2架173的载具C2向第2叶片143移载,如工序S11所示地将该处理后的晶圆W2收纳于晶圆收纳容器15。以下,重复以上的工序,直至收纳于晶圆收纳容器15的所有处理前的晶圆WF的处理结束。
如上所述,在本实施方式的气相成长装置1中,借助反应炉11进行处理的期间,将下一处理前的晶圆WF从晶圆收纳容器15取出来准备,或将处理后的晶圆WF收纳于晶圆收纳容器15,由此,能够使仅搬运所花的时间变为极少。该情况下,如本实施方式的架17所示,若将装载锁定室13的载具C的待机数设定成2个以上,则仅搬运所花的时间的缩短自由度进一步变高。并且,若考虑装载锁定室13的专有空间,则与将多个载具C左右排列相比,上下排列成多层的话,气相成长装置1的整体的专有空间变小。但是,将多个载具C上下排列多层时,有在处理前的晶圆WF的上部支承载具C的情况,有尘埃落下至处理前的晶圆WF的可能。然而,本实施方式的气相成长装置1中,以处理前的晶圆WF搭载于装载锁定室13的架17的最上层的架(第1架172)的方式,追加工序S3、S8,将空的载具C2向第1架172移载,由此,处理前的晶圆WF被搭载于最上层的载具C。结果,能够抑制由载具C引起的颗粒附着于晶圆WF,能够提高LPD品质。
进而,若在上述的流程重复多个硅外延晶圆的制造,则不仅在构成反应室111的腔的内壁、基座112,在搭载晶圆WF而被向反应室111投入的载具C的表面,由反应气体引起的多晶硅、其分解产物也逐渐堆积。为了将该堆积物定期地除去,以既定的频率执行反应室111及载具C的洗涤处理。图11及图12是表示本实施方式的气相成长装置1的载具C的洗涤流程的图。
图11的工序S20表示,结束外延层的生成等的气相成长处理而开始洗涤处理的等待状态,空的载具C1被支承于装载锁定室13的第1架172,空的载具C2被支承于第2架173,装载锁定室13为非活性气体氛围。
在接下来的工序S21中,打开装载锁定室13的第2门132,将空的状态的载具C1载置于第1机器人121的第1叶片123,打开反应炉11的闸门阀114,经由该闸门阀114将载具C1向基座112移载。该移载的流程如参照图4所作说明。该工序S21中,反应炉11中,进行相对于载具C1及反应室111的腔内壁、基座112等的洗涤处理。本例的洗涤处理通过蚀刻处理进行。
即,将空的载具C1移载至反应室111的基座112,关闭闸门阀114,借助加热灯使反应室111升温至既定的洗涤温度(例如1190℃),借助气体供给装置113将氯化氢HCl等的洗涤用气体(蚀刻气体)以既定流量供给既定时间。由此,在载具C1的表面、反应室111的腔内壁、基座112的表面堆积的多晶硅、其分解产物被蚀刻(消融)。
洗涤处理结束后,打开反应炉11的闸门阀114,将第1机器人121的第1叶片123***反应室111,载置洗涤处理后的载具C1,从反应室111取出,关闭闸门阀114后,打开第2门132,移载至装载锁定室13的第1架172(工序S22)。接着,将支承于第2架173的空的载具C2载置于第1机器人121的第1叶片123,如图12的工序S23所示,打开闸门阀114,将该载具C2经由晶圆移载室12移载至反应炉11的基座112。
在该工序S23中,在反应炉11中,进行相对于载具C2及反应室111的腔内壁、基座112等的洗涤处理。即,将空的载具C2移载至反应室111的基座112,关闭闸门阀114,借助加热灯使反应室111升温至既定的洗涤温度(例如1190℃),借助气体供给装置113将氯化氢HCl等的洗涤用气体(蚀刻气体)以既定流量供给既定时间。由此,在载具C2的表面、反应室111的腔内壁、基座112的表面堆积的多晶硅、其分解产物被蚀刻(消融)。
洗涤处理结束后,打开反应炉11的闸门阀114,将第1机器人121的第1叶片123***反应室111,载置洗涤处理后的载具C2,从反应室111取出,关闭闸门阀114后,打开第2门132,移载至装载锁定室13的第2架173(工序S24)。通过以上的工序S20~S24,包括一对载具C1、C2的反应炉11的洗涤处理完成。
