Abstract:
A hard mask and a method of creating thereof are provided. A first layer is deposited that is configured to provide at least one of a chemical and a mechanical adhesion to a layer immediately below it. A second layer is deposited having an etch selectivity that is faster than the first layer. A third layer is deposited having an etch selectivity that is slower than the first and second layers. The third layer has a composite strength that is higher than the first and second layers. A photoresist layer is deposited on top of the third layer and chemically removed above an inner opening. The third layer and part of the second layer are anisotropically etched through the inner opening. The second layer and the first layer are isotropically etched to create overhang regions of the third layer.

Claim (Index 16):
The method of  claim 12 , wherein:\n the first layer comprises polysilicon (poli-Si); the second layer comprises silicon dioxide (SiO 2 ); and the third layer comprises silicon nitride (SiN).
