摘要:
A semiconductor device may include a semiconductor substrate and first and second transistors. The first transistor may have a first gate structure on the semiconductor substrate, and the first gate structure may include a first gate insulating layer between a first gate electrode and the semiconductor substrate. The first gate insulating layer may include first and second dielectric materials with the second dielectric material having a greater dielectric constant than the first dielectric material. Moreover, the first gate electrode may be in contact with the second dielectric material. The second transistor may have a second gate structure on the semiconductor substrate, with the second gate structure including a second gate insulating layer between a second gate electrode and the semiconductor substrate. Related methods are also discussed.
摘要:
A semiconductor structure includes a material layer on a substrate and to be patterned, an amorphous carbon layer on the material layer to be patterned, an N-free anti-reflective layer on the amorphous carbon layer, and a photoresist layer on the N-free anti-reflective layer. The N-free anti-reflective layer contains SiCXOYHZ as a main element. Related methods of patterning semiconductor structures also are provided.
