基板处理装置及基板处理方法
技术领域
本发明涉及一种基板处理装置,更特别地,涉及使用一个或多个气体喷射器用于在基板上形成薄膜的基板处理装置。另外,本发明涉及一种利用本发明的基板处理装置在形成有超微图案的基板上形成均匀和致密薄膜的基板处理方法。
背景技术
通常,为了制造太阳能电池(Solar Cell)、半导体元件、平板显示设备等,需要在基板表面上应形成规定的薄膜层、薄膜电路图案、或光学图案。为此,执行半导体制造工艺,并且半导体制造工艺的实例包括将具有特定材料的薄膜沉积于基板上的薄膜沉积工序,通过使用感光材料选择性暴露薄膜的感光工序,去除选择性暴露部分的薄膜以形成图案的蚀刻工序等。
这样的半导体制造工艺在基板处理装置内执行,这种基板处理装置基于为相应工序的最佳环境而设计,并且近来,大量使用用于执行基于等离子的沉积或蚀刻处理的基板处理装置。
基于等离子的基板处理装置的实例包括:通过使用等离子形成薄膜的PECVD(Plasma Enhanced Chemical Vapor Deposition:等离子增强的化学气相沉积)装置,以及用于对薄膜蚀刻和形成图案的等离子蚀刻装置等。
在现有的半导体制造工艺和装置中,由于在图案内部和图案上剩余的源气体不能够从形成有复杂和高纵横比图案的基板上吹扫,因此均匀的薄膜不能够形成在图案内部和图案上,并且由于这种原因,在图案之间或图案的内部和图案顶部之间的台阶覆盖(Stepcoverage)不均匀,从而导致工艺生产性的降低。

技术效果
由于本发明的基板处理装置包括多个源气体喷射器或多个反应气体喷射器,因此均匀薄膜可以在图案内部和图案上部形成,其中此图案在基板上形成、复杂、并且纵横比很高。
此外,由于本发明的基板处理装置包括多个吹扫气体喷射器,因此图案内部和图案上部残留的源气体可以从基板上适当地吹扫(去除),其中此基板上形成有复杂和高纵横比的图案,因此,均匀薄膜可形成于图案内部和图案上部。
此外,由于本发明的基板处理装置包括多个源气体喷射器或多个反应气体喷射器,因此源气体充分吸附到基板表面上,或者源气体和反应气体的反应在基板表面上充分地执行,从而提高了沉积的薄膜质量。
此外,在本发明的基板处理装置中,等离子电极可形成于气体喷射器中,或者通过气体喷射器喷射激活的自由基气体,薄膜可形成于基板表面上,或者可以在基板表面上形成的薄膜上进行表面处理,因此,沉积的薄膜质量得到了提高。
此外,在本发明的基板处理装置中,通过使用用于沉积的气体喷射器或构成等离子电极的一部分或全部的气体喷射器,在基板上沉积薄膜的过程或者可重复地执行沉积之后基于等离子的沉积表面处理,从而提高在基板上沉积的薄膜质量。
此外,在本发明的基板处理装置中,可使用用于沉积的气体喷射器或构成等离子电极的一部分或全部的气体喷射器,并且通过重复地执行在基板上沉积薄膜的过程或者通过喷射由等离子激活的气体执行后沉积表面处理,在基板上沉积的薄膜质量得到了提高。
此外,在本发明的基板处理装置中,等离子电极可形成在与用于沉积的气体喷射器相分离的气体喷射器中,或激活的自由基气体可通过气体喷射器喷射,通过将杂质添加至喷射的气体中,杂质可注入到在沉积过程或表面处理过程中在基板上形成的薄膜中,从而提高了沉积的薄膜质量。
此外,由于本发明的基板处理装置包括多个源气体喷射器或多个反应气体喷射器,因此源气体充分地吸附到基板表面上,或者源气体和反应气体的反应在基板表面上充分地进行,因此,在通过旋转气体喷射器或基板支架而形成的原子层的沉积中,可通过一次旋转来实现原子层的沉积,并且可以补偿由于旋转速度的增加引起的气体供给或反应的持续时间的不充足,从而提高沉积的薄膜质量且增加薄膜的沉积速度。
此外,由于本发明的基板处理装置包括多个源气体喷射器、多个反应气体喷射器、或自由基气体喷射器或具有一个或多个等离子电极的气体喷射器,因此可以通过所述多个源气体喷射器喷射金属前体或含硅气体,或所述多个反应气体喷射器可喷射含氧气体或含氮气体,从而提高沉积的薄膜质量。
