摘要:
Techniques related to forming selective gate spacers for semiconductor devices and transistor structures and devices formed using such techniques are discussed. Such techniques include forming a blocking material on a semiconductor fin, disposing a gate having a different surface chemistry than the blocking material on a portion of the blocking material, forming a selective conformal layer on the gate but not on a portion of the blocking material, and removing exposed portions of the blocking material.
