发明名称 Encapsulation of Closely Spaced Gate Electrode Structures
摘要 Generally, the subject matter disclosed herein relates to sophisticated semiconductor devices and methods for forming the same, wherein the pitch between adjacent gate electrodes is aggressively scaled, and wherein self-aligning contact elements may be utilized to avoid the high electrical resistance levels commonly associated with narrow contact elements formed using typically available photolithography techniques. One illustrative embodiment includes forming first and second gate electrode structures above a semiconductor substrate, then forming a first layer of a first dielectric material adjacent to or in contact with the sidewalls of each of the first and second gate electrode structures. The illustrative method further includes a step of forming a second layer of a second dielectric material on the first layer, followed by forming a third layer of a third dielectric material on the second layer, wherein forming the third layer further comprises forming a first horizontal portion of the third layer above a surface of the semiconductor substrate between the first and second gate electrode structures.
