| 摘要 |
<p>One illustrative method disclosed herein includes forming a mandrel structure above a semiconductor substrate, performing an oxidation process to oxidize at least a portion of the mandrel structure so as to thereby define oxidized regions on the mandrel structure, removing the oxidized regions to thereby defined a reduced thickness mandrel structure, forming a plurality of fins on the reduced thickness mandrel structure and performing an etching process to selectively remove at least a portion of the reduced thickness mandrel structure so as to thereby expose at least a portion of each of the fins.</p> |
