Abstract:
Methods for manufacturing semiconductor devices may include forming a stack structure including layers stacked on a substrate, forming a mask pattern on the stack structure, and patterning the stack structure using the mask pattern such that the stack structure has an end portion with a stepped profile. The patterning of the stack structure may include performing a pad etching process of etching the stack structure using the mask pattern as an etch mask, and performing a mask etching process of etching a sidewall of the mask pattern. The performing of the mask etching process may include irradiating an ion beam onto the mask pattern, which may be irradiated at a first tilt angle with respect to the sidewall of the mask pattern and at a second tilt angle with respect to a top surface of the mask pattern. The first tilt angle may be different from the second tilt angle.

Claim (Index 11):
The method of  claim 10 , further comprising:\n removing portions of the mask pattern remaining after the patterning of the stack structure; forming a plurality of vertical patterns in the stack structure, the vertical patterns penetrating the stack structure and connecting to the substrate; selectively removing the sacrificial layers to form recess regions between the insulating layers; and forming gate electrodes in the recess regions, wherein the gate electrodes respectively comprise pads that correspond to the end portion of the stack structure that has the stepped profile.
