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 13):
The method of  claim 12 , wherein the performing of the mask etching process comprises:\n providing a grid, wherein: the grid has a first surface and a second surface opposite to each other; and the first surface faces a top surface of the substrate; and adjusting the first tilt angle and the second tilt angle by adjusting an angle between the top surface of the substrate and the first surface of the grid, wherein the ion beam is irradiated to the substrate through a plurality of holes penetrating the grid.
