    • The present invention relates generally to semiconductor devices, and more particularly, to a structure and method of forming a spacer adjacent to a gate in a fin field effect transistor (FinFET) device without resulting in substrate gouging or a spacer foot. A conformal spacer layer may be formed around a plurality of fins and a gate, wherein the conformal spacer layer may have a thickness above the plurality of fins that is at least one-half the distance between the individual fins. An isotropic etch may be used to remove excess spacer material around the plurality of fins (but not between the fins) and around the gate. An anisotropic etch may be used to remove the remaining spacer material from between the fins and around the gate, leaving a spacer adjacent to the gate without gouging the substrate surface between the fins.
    • 本发明一般涉及半导体器件,更具体地说,涉及在鳍状场效应晶体管(FinFET)器件中形成与栅极相邻的隔离物而不产生衬底气刨或间隔脚的结构和方法。 可以在多个翅片和栅极周围形成共形间隔层,其中保形间隔层可以具有在多个翅片之上的厚度,其为单个翅片之间的距离的至少一半。 可以使用各向同性蚀刻来去除多个翅片周围的多余的隔离材料(而不是在翅片之间)和栅极周围。 可以使用各向异性蚀刻从散热片和栅极之间移除剩余的间隔物材料,留下与栅极相邻的间隔物,而不在翅片之间刨削基板表面。
