    Abstract: One illustrative method disclosed herein includes, among other things, forming a sacrificial gate structure above a semiconductor substrate, forming a sidewall spacer adjacent opposite sides of the sacrificial gate structure, removing the sacrificial gate structure and forming a replacement gate structure in its place, at some point after forming the replacement gate structure, performing an etching process to reduce the height of the spacers so as to thereby define recessed spacers having an upper surface that partially defines a spacer recess, and forming a spacer etch block cap on the upper surface of each recessed spacer structure and within the spacer recess.

    Abstract translation: 本文公开的一种说明性方法包括在半导体衬底之上形成牺牲栅极结构,在牺牲栅极结构的相对侧面上形成侧壁隔离物,去除牺牲栅极结构并在其位置形成替代栅极结构 在形成替代栅极结构之后的某些点,执行蚀刻工艺以降低间隔物的高度,从而限定具有部分限定间隔物凹槽的上表面的凹进的间隔件,并且在上表面上形成间隔物蚀刻块帽 每个凹进的间隔结构和间隔凹槽内。
