图2描绘根据本公开的一些实施例的、适合与具有气体分配板的喷淋头一起使用的工艺腔室。
为了便于理解,在可能的情况下,已使用相同的元件符号来指定各附图共有的相同的元件。附图并非按照尺寸绘制,并且附图可能为了清楚而简化。一个实施例的元件和特征可有益地并入其他实施例中而无须进一步阐释。
具体实施方式
本文中提供具有可拆卸气体分配板的喷淋头的实施例。在至少一些实施例中,本发明的喷淋头可有益地允许用于气体分配板的移除和替换,由此提供相比具有永久地接合的气体分配板的常规喷淋头更长的有效寿命以及更具成本效益的替换气体分配板的方式的喷淋头。
图1描绘根据本公开的一些实施例的具有气体分配板的喷淋头。喷淋头100通常包含主体102、气体分配板104和夹具110,所述夹具110配置成可移除地将气体分配板耦接至主体102。
主体102包含第一侧150、第二侧140以及形成在主体102中而从第一侧150延伸至第二侧140的多个通孔116。多个通孔116便于工艺气体通过主体102而至气体分配板104。在一些实施例中,通孔116可以是埋头孔(例如,所示的埋孔118)以减少通孔116处的残余电场,并促进至气体分配板104的更均匀的气体流。在一些实施例中,可在主体102的第一侧150中形成凹室114以促进至多个通孔116的更均匀的工艺气体的分配。主体102可由任何适合的工艺兼容材料(例如,铝)制成。通过由诸如铝之类的导电材料制成主体102,主体102可充当电极,以便例如促进从提供至喷淋头100的工艺气体形成等离子体。在一些实施例中,能以材料涂覆主体102的第二侧140以保护第二侧140免受离子、等离子体或点燃。例如,在一些实施例中,涂覆可以是三氟化钇(YF3)涂覆。可使用各种技术将涂层设置在主体102的第二侧140上。用于涂覆主体102的第二侧140的一些示例性非限制性方法可包括:使用对靶材材料的电子束诱导活化从由涂覆材料制成或以其他方式包括涂覆材料的靶材将涂层沉积或蒸发到主体102上。
在一些实施例中,可在主体102的表面中形成一个或更多个通道以容纳一个或更多个O形环和/或射频(RF)垫片(示出的O形环130、132、134以及RF垫片108、126)。当存在时,O形环130、132、134在主体102与夹具110或工艺腔室(未示出)的表面之间提供密封。O形环130、132、134可由任何适合的材料(例如,橡胶)制成以促进上述的密封。RF垫片108、126促进RF功率例如从RF源至主体102和夹具110的导电性。例如,可从RF功率供应器(诸如,下文所述的RF电源286)将RF功率提供至耦接至主体102且与一个或更多个RF垫片(例如,RF垫片126)接触的部件。RF垫片108、126可由任何适合的导电材料(例如,不锈钢)制成。
气体分配板104促进从主体102提供的工艺气体例如经由在气体分配板104中形成的多个气体分配孔142而向工艺腔室的处理容积的分配。气体分配孔142能以适用于提供所需的处理气体分配的方式来布置。例如,在一些实施例中,当气体分配板104耦接至主体102时,气体分配孔142可布置为绕主体102的通孔116设置的群集。
气体分配板104可由任何适合的材料制成,以抵抗在暴露于等离子体(例如,在处理期间形成在工艺腔室中的等离子体)期间的降级。例如,在一些实施例中,气体分配板104可由单晶硅(Si)制成。单晶硅并非典型地用作用于气体分配板的材料,至少部分地归因于单晶硅具有相比受青睐的材料碳化硅更快的蚀刻速率。然而,发明人已观察到,相比用于制造气体分配板的常规材料(诸如,碳化硅)(SiC),单晶硅较不易受表面粗糙度改变、起弧和微掩蔽(micro-masking)的影响,并且在提升的温度(例如,高于约150摄氏度)下提供更好的操作性。此外,相比常规材料,单晶硅更易于取得且能以更低的成本获得。此外,在将喷淋头100使用于涉及含硅气体的基板工艺的实施例中,由硅制成的气体分配板104降低由于气体分配板104的降级而造成的污染的实例。
在一些实施例中,气体分配板104由单晶硅材料制成,所述单晶硅材料具有在约60Ω-cm与90Ω-cm之间的高电阻率以减少起弧。如上所述,发明人已观察到,低电阻率气体分配板(例如,具有约0.005-0.015Ω-cm的电阻率的气体分配板)在源功率处于162MHz而大于或等于2000瓦的工艺期间将起弧。由此,当喷淋头100用在高源功率工艺中时,气体分配板104的高电阻率有益地减少起弧。在一些实施例中,可掺杂通过其来获得单晶硅的晶锭以改变晶锭的电阻率。例如,能以诸如硼之类的高电阻率材料掺杂或涂覆单晶硅晶锭以增加材料的电阻率。在一些实施例中,如果气体分配板104由低电阻率材料制成,则能以高电阻率材料处理、涂覆或掺杂气体分配板104,以增加气体分配板104的电阻率。
气体分配板104可具有足以提供所需的气体分配和适合的有效功能寿命的任何适合的厚度。此外,在一些实施例中,气体分配板104可具有适合的厚度,足以确保当气体分配板104耦接至主体102时与设置在气体分配板104与主体102之间的一个或更多个热垫片(示出的三个热垫片120、122、124)的持续接触。例如,在一些实施例中,气体分配板104的厚度可经选择,使得由夹具110在气体分配板104的边缘处提供的力而导致的气体分配板104的躬曲量小于当压缩时热垫片120、122、124变形的量,由此确保当夹持时与热垫片120、122、124中的每一个的持续接触。替代地或组合地,在一些实施例中,气体分配板104的厚度可经选择,以提供适于减少等离子体穿透且改善气体分配板104的有效功能寿命的气体分配孔142的纵横比(aspect ratio)。例如,在气体分配孔142具有约0.5mm直径的实施例中,气体分配板104可具有约9mm的厚度。
夹具110促进将气体分配板104耦接至主体102。在一些实施例中,夹具110经由紧固件106来促进此类耦接,所述紧固件106提供至形成在主体102中的通孔136,所述通孔136对应于形成在夹具中的螺纹孔138。夹具110可由任何工艺兼容的导电材料(例如,铝)制成。在一些实施例中,能以喷洒涂层(例如,氧化钇(Y2O3))来涂覆夹具110以减小夹具110在等离子体环境中的降级。在一些实施例中,替代地,能以氧化铝涂层来阳极化夹具110。
在一些实施例中,夹具110可包括形成在夹具110的表面中的一个或更多个通道以容纳一个或更多个O形环和RF垫片(示出的O形环128和RF垫片148)。当存在时,O形环128对气体分配板104提供缓冲,以防止当夹持至主体102时气体分配板104的破损。当存在时,RF垫片148促进RF功率从主体102通过夹具110而至气体分配板104的导电性,由此允许气体分配板104充当RF电极。对气体分配板104提供RF电流路径也遮蔽了在主体102与气体分配板104之间的间隙146,这例如在主体102的通孔116处减少了起弧。O形环128和RF垫片148可由任何材料(例如上文中针对O形环130、132、134和RF垫片108、126所讨论的材料)制成。
