Description
技术领域
本发明涉及一种薄膜沉积设备及薄膜沉积方法,特别是涉及一种多模式薄膜沉积设备及薄膜沉积方法。
背景技术
有机发光二极管(Organic Light-Emitting Diode,OLED)中的有机半导体材料及低功函数电极极易受氧气与水气劣化,有效的封装技术以增加元件稳定性及使用寿命一直是有机发光二极管商品化过程的挑战。传统封装方法制作成本高,且不具有可挠曲性,无法满足需求。利用原子层沉积(ALD)或等离子体辅助化学气相沉积(PECVD)薄膜封装技术来制备可挠性阻障薄膜(barrier film)已成为趋势。
原子层沉积制作工艺沉积高致密低缺陷无机薄膜如氧化铝(Al2O3)等,由于制作工艺速率慢,为达有效的有机发光二极管封装需求的厚度(约20~30nm),制作工艺将需耗费约200~300分钟,无法有效降低制造成本,市场接受度低。若单纯使用等离子体辅助化学气相沉积制作工艺虽可大幅增加薄膜沉积速度,但有机发光二极管元件却容易受到等离子体环境中高能离子轰击而造成损害(plasma induced damage)。若结合两者制作工艺技术的优点,先利用原子层沉积制作工艺沉积数十个原子层(~2nm,20min)的无缺陷薄膜(即氧化铝薄膜),再利用等离子体辅助化学气相沉积制作工艺沉积较厚的氮化硅(SiNx)用以保护氧化铝层避免于大气中产生水解。由于原子层沉积制作工艺所制备的无缺陷薄膜甚为致密,于等离子体辅助化学气相沉积制作工艺中可保护有机发光二极管元件不受等离子体损害的影响。如此制作工艺方法可大幅降低阻障薄膜的制作工艺所需时间(由原4-5小时降到0.5小时左右)。
然而,对于现今制作工艺技术而言,原子层沉积制作工艺与等离子体辅助化学气相沉积制作工艺分属两个不同制作工艺腔体,不仅设备成本高,在元件转移(transfer)的过程中,未完成封装的有机发光二极管元件会暴露于环 境中,造成阻障薄膜(barrier film)品质的降低。此外,等离子体辅助化学气相沉积制作工艺与原子层沉积制作工艺技术截然不同,等离子体辅助化学气相沉积制作工艺需透过气体喷洒头(showerhead)使混合的制作工艺气体均匀分布,并产生等离子体以解离制作工艺气体形成镀膜前驱反应物,因此,气体喷洒头会设计1~3层的气体扩散空间以作为缓冲区域,用于达到均匀出气的目的。而原子层沉积制作工艺则是讲求在最短的工作周期(low cycle time)让气体前驱物饱和分布并附着在制作工艺基板上。因此,若单纯利用等离子体辅助化学气相沉积制作工艺的气体喷洒头来进行原子层沉积制作工艺,制作工艺气体将需要充满整个气体喷洒头以及制作工艺腔空间才能达到饱和分布,如此一来,势必造成工作周期及气体使用量的增加。
发明内容
本发明的目的在于提供一种多模式薄膜沉积设备,适于将基板在单一腔体中进行不同模式的薄膜沉积制作工艺。
为达上述目的,本发明的一实施例提供一种多模式薄膜沉积设备。多模式薄膜沉积设备包括反应腔室、承载座、气体喷洒头、惰性气体供应源、第一进气系统与第二进气系统。反应腔室具有第一开口及第二开口,第一开口与第二开口为同一轴向,以贯穿反应腔室。承载座适于承载基板,且设置于反应腔室中。气体喷洒头具有气体混合室与多个气孔,其中所述气孔位于气体混合室的一侧,且所述气孔朝向承载座,气体混合室通过所述气孔而与反应腔室连通。第一进气系统,适于提供第一薄膜沉积模式时所需的第一制作工艺气体,且第一进气系统连接于该第一开口。惰性气体供应源,连接于气体喷洒头的气体混合室,适于提供不与第一制作工艺气体反应的惰性气体。第二进气系统,适于提供第二薄膜沉积模式时所需的第二制作工艺气体,且第二进气系统连接于气体喷洒头的气体混合室。
本发明的又一实施例是提出一种利用上述的多模式薄膜沉积设备进行的薄膜沉积方法,其包括:提供基板,配置于承载座上。进行该第一薄膜沉积模式,同步开启第一进气系统及惰性气体供应源,使第一进气系统经由第一开口提供第一制作工艺气体至反应腔室,同时惰性气体经由气体喷洒头的所述气孔进入到反应腔室,接着控制惰性气体的进气,使气体混合室与所述气孔的压力大于反应腔室,通过气体喷洒头喷出惰性气体以将第一制作工艺 气体附着在基板上,并于基板上形成第一薄膜,之后关闭第一进气系统及惰性气体供应源。进行该第二薄膜沉积模式,开启第二进气系统,使第二制作工艺气体经由气体喷洒头的所述气孔进入到反应腔室,并于基板上形成第二薄膜。

具体实施方式
图1为本发明一实施例的多模式薄膜沉积设备的示意图。请参照图1,其为本发明一实施例的多模式薄膜沉积设备。多模式薄膜沉积设备1包含反应腔室10、承载座20、第一进气系统30、气体喷洒头40、惰性气体供应源50及第二进气系统60。反应腔室10具有第一开口12与第二开口14,第一开口12与第二开口14的开口方向可为同一轴向,以横向的贯穿整个反应腔室10。承载座20设置在反应腔室10中,且适于承载基板22。举例而言,在本实施例中,多模式薄膜沉积设备1可还包括承载座升降机构24,连接于承载座20,适于调节承载座20的位置。第一进气系统30适于提供第一薄膜沉积模式时所需的第一制作工艺气体PS1,且第一进气系统30连接于第一开口12。其中,承载座20的设置方向平行于第一开口12与第二开口14的轴向,使由第一开口12进入的第一制作工艺气体PS1能沿着基板22设置方 向流动至第二开口14。气体喷洒头40具有气体混合室42与多个气孔44,所述气孔44位于气体混合室42的一侧,且朝向承载座20,气体混合室42通过所述气孔42而与反应腔室10连通。惰性气体供应源50连接于气体喷洒头40的气体混合室42,以适于提供惰性气体IG。要注意的是,此处所指的惰性,意指不与第一制作工艺气体PS1产生反应的气体,在一实施例中,惰性气体IG可为元素周期表上VIIIA族,例如是:氩(Ar),但不以此为限。第二进气系统60连接于气体喷洒头40的气体混合室42,适于提供第二薄膜沉积模式时所需的第二制作工艺气体PS2。
在本实施例中,多模式薄膜沉积设备1还可包括抽气系统70,连接于反应腔室10的第二开口14。抽气系统70例如是帮浦,但不以此为限。抽气系统70主要为在模式转换或是模式执行过程中,提供抽气作用,将反应腔室10及气体混合室42中的气体及制作工艺反应物抽出,避免造成污染。
详细来说,第一进气系统30包含第一气体供应源32与第二气体供应源34,第一气体供应源32是透过第一气体供应管路36而与反应腔室10的第一开口12连接,第二气体供应源34是透过第二气体供应管路38而与反应腔室10的第一开口12连接。在本实施例中,第一薄膜沉积模式为原子层沉积(Atomic Layer Deposition,ALD)模式。当执行第一薄膜沉积模式时,第一制作工艺气体PS1会包含第一前驱物气体PC1及第二前驱物气体PC2,且第一前驱物气体PC1及第二前驱物气体PC2分别经由第一气体供应源32与第二气体供应源34所提供。
此外,在另一实施例中,第一薄膜沉积模式也可为单晶片等离子体辅助原子层沉积(Plasma-enhanced Atomic Layer Deposition,PEALD)模式,此时多模式薄膜沉积设备1还包括第二电压供应源82,耦接于第一进气系统30。在执行单晶片等离子体辅助原子层沉积模式时,第二电压供应源82可对第一制作工艺气体PS1施加偏压以产生等离子体。更进一步来说,第二电压供应源82可对第一制作工艺气体PS1中的第一前驱物气体PC1与第二前驱物气体PC2其中的施加偏压,使其中一前驱物气体形成单晶片等离子体,以在基板上形成薄膜。
另一方面,本发明的多模式薄膜沉积设备1还可包括第一电压供应源80,耦接于气体喷洒头40,且第二薄膜沉积模式为等离子体辅助化学气相沉积(Plasma-enhanced chemical vapor deposition,PECVD)模式。在执行等离 子体辅助化学气相沉积模式时,第一电压供应源80可对由第二进气系统60进入气体喷洒头40的第二制作工艺气体PS2施加偏压,以产生等离子体,并用于执行等离子体辅助化学气相沉积模式。
此外,本发明的多模式薄膜沉积设备1可包含流量控制单元90,分别与第一进气系统30、第二进气系统60以及惰性气体供应源50连接,以在不同的薄膜沉积模式进行中,控制第一制作工艺气体PS1、第二制作工艺气体PS2与惰性气体IG的气体流量。
以下将搭配图2及图3针对多模式薄膜沉积设备在各薄膜沉积模式中的运作情形进行描述:
图2为本发明一实施例的多模式薄膜沉积设备进行第一薄膜沉积模式时,制作工艺气体流动的示意图。请参照图2,首先,提供基板22,配置于反应腔室10的承载座20上。接着,进行第一薄膜沉积模式。请参照图2,当进行第一薄膜沉积模式时,同步开启第一进气系统30及惰性气体供应源50,使第一进气系统30经由第一开口12提供第一制作工艺气体PS1至反应腔室10,同时惰性气体IG经由气体喷洒头40的所述气孔44进入到反应腔室10。此时,流量控制单元90控制惰性气体供应源50调控惰性气体IG的进气,使气体喷洒头40的气体混合室42与所述气孔44的压力大于反应腔室10。详细来说,第一制作工艺气体PS1由第一开口12进入到反应腔室10时,第一制作工艺气体PS1原本会先充满反应腔室10与气体混合室42,并顺着流动方向而往第二开口14流出,但通过气体喷洒头40喷出的惰性气体IG,压力差的关致使第一制作工艺气体PS1无法经由所述气孔44进入到气体混合室42中,如此一来,可避免第一制作工艺气体PS1薄膜沉积在气孔44上造成阻塞。再者,若无惰性气体IG的灌入来充满气体喷洒头40的气体混合室42与所述气孔44,当进行第一薄膜沉积模式时,第一制作工艺气体PS1便须充满整个反应腔室10及气体喷洒头40的气体混合室42与所述气孔44的空间,如此将会造成第一制作工艺气体PS1的浪费。进一步来说,由于反应腔室10通入有不与第一制作工艺气体PS1反应的惰性气体IG,因此第一制作工艺气体PS1在反应腔室10中便会如图2所示,顺着方向往第二出口14流动。在本实施例中,第一开口12与第二开口14的开口方向为同一轴向,且横向贯穿反应腔室10,气体喷洒头40的所述气孔44朝向承载座20,如此的配置关系可使从第一开口12进入的第一制作工艺气体PS1在 往第二出口14方向流动的过程中,通过气体喷洒头40喷出的惰性气体IG,以将第一制作工艺气体PS1附着在基板22上,并于基板22上形成第一薄膜。
更详细而言,在本实施例中,第一薄膜沉积模式为原子层沉积制作工艺模式,因此第一制作工艺气体PS1包含至少二种不同的前驱物气体(如前所述的第一前驱物气体PC1与第二前驱物气体PC2),二前驱物气体可分别由第一气体供应源32与第二气体供应源34提供,并经由第一开口12进入到反应腔室10。其中,第一前驱物气体PC1与第二前驱物气体PC2具有时间间隔地输入反应腔室10中。详细来说,在原子层沉积制作工艺模式中,会先将第一前驱物气体PC1输入于反应腔室10中,此时气体喷洒头40同步提供惰性气体IG,流量控制单元90会控制第一前驱物气体PC1与惰性气体IG的进气量,使气体混合室42的压力大于反应腔室10。在一实施例中,第一前驱物气体PC1与惰性气体IG在反应腔室10的流量比例介于2/3至5/4之间。然而,第一前驱物气体PC1与惰性气体IG在反应腔室10的流量比例流量并不以上述为限,控制单元90控制第一前驱物气体PC1与惰性气体IG的进气量,使第一前驱物气体PC1仅于基板22表面达到饱和分布即可执行原子层沉积制作工艺模式。之后,通过抽气系统70经第二开口14对反应腔室10抽气,以将第一前驱物PC1及惰性气体IG抽出。于一时间间隔后,再将第二前驱物气体PC2输入,此时同步灌入惰性气体IG,详细情形与第一前驱物气体PC1雷同,于此不再赘述。当第二前驱物气体PC2接触到基板22时,反应产生第一薄膜,此时关闭第一进气系统30及惰性气体供应源50,以完成原子层沉积制作工艺模式。在一实施例中,在进行原子层沉积制作工艺时,也可全程开启抽气系统70,以调节反应腔室10的气体压力。
图3为本发明一实施例的多模式薄膜沉积设备进行第二薄膜沉积模式时,制作工艺气体流动的示意图。另一方面,请参考图3,当进行第二薄膜沉积模式时,开启第二进气系统60,第二制作工艺气体PS2会先进入到气体喷洒头40的气体混合室42充分混合后,再经由所述气孔44进入到反应腔室10。在本实施例中,第二薄膜沉积模式可为等离子体辅助化学气相沉积制作工艺模式。当气体喷洒头40提供的第二制作工艺气体PS2进入到反应腔室10时,开启第一电压供应源80,以提供射频偏压于第二制作工艺气体PS2,进而产生等离子体,以于基板22上形成第二薄膜。
其中,由于在第一薄膜沉积模式运作时,会注入惰性气体IG于反应腔 室10中,因此不需过多的第一制作工艺气体PS1即可进行第一薄膜沉积制作工艺。此外,也因为惰性气体IG的注入,能够避免第一制作工艺气体PS1阻塞气体喷洒头40的所述气孔40,以维持第二薄膜沉积模式运作时的品质。据此,第一薄膜沉积模式(原子层沉积制作工艺)与第二薄膜沉积模式(等离子体辅助化学气相沉积制作工艺)时,皆可在同一该反应腔室中进行。
此外,当进行原子层沉积制作工艺模式时,第一电压供应源为关闭状态。然而当多模式薄膜沉积设备1包括有耦接于第一进气系统30的第二电压供应源82时,还可进一步执行单晶片等离子体辅助原子层沉积制作工艺。执行单晶片等离子体辅助原子层沉积制作工艺时,开启第二电压供应源82,使第一前驱物气体PC1与第二前驱物气体PC2其中一形成单晶片等离子体,以于基板22上形成第三薄膜。
本发明的多模式薄膜沉积设备在第一薄膜沉积模式中,通过控制第一制作工艺气体与惰性气体在反应腔室的流量,以使第一制作工艺气体能在基板上产生反应并进行薄膜沉积。此外,由于在第一薄膜沉积模式进行时,会加入惰性气体,如此可避免第一制作工艺气体流入气孔中而造成阻塞,还可避免第一制作工艺气体充满整个气体喷洒头与反应腔室,造成第一制作工艺气体的浪费。因此,本发明的多模式薄膜沉积设备在各薄膜沉积模式执行时,可在同一反应腔室中进行,而不需因应不同的薄膜沉积需求而将基板移转到不同的腔室中,能省下腔室之间基板移转过程中所耗费的时间。
虽然已结合以上实施例公开了本发明,然而其并非用以限定本发明,任何所属技术领域中熟悉此技术者,在不脱离本发明的精神和范围内,可作些许的更动与润饰,故本发明的保护范围应以附上的权利要求所界定的为准。
