Abstract:
A method of manufacturing a semiconductor device includes providing a substrate structure including a substrate and a semiconductor column vertically protruding from the substrate, sequentially forming a first protective layer and a second protective layer on the substrate;, etching a portion of the second protective layer to expose a portion of the first protective layer on the substrate and a portion of the first protective layer on an upper surface of the semiconductor column, removing the exposed portion of the first protective layer on the substrate to expose a lower portion of the semiconductor column, removing a remaining portion of the second protective layer, and forming a first contact material layer on the substrate and in contact with the lower portion of the semiconductor column. The first contact material layer in contact with the lower portion of the semiconductor column does not increase the source series resistance.

Claim (Index 3):
The method of  claim 1 , wherein the semiconductor column comprises a semiconductor layer and a hardmask layer on the semiconductor layer, the method further comprising, prior to forming the first contact material layer:\n removing the hardmask layer.
