Abstract:
1. A method of fabricating an integrated circuit device, the method comprising: forming fin-shaped transistor channel regions having respective widths that are the same and protruding from coplanar first and second regions of a substrate surface; and after forming the fin-shaped transistor channel regions having the respective widths that are the same, selectively altering the respective widths of ones of the fin-shaped transistor channel regions protruding from the first region while maintaining the respective widths of ones of the fin-shaped transistor channel regions protruding from the second region, wherein, after selectively altering the respective widths, the respective widths of the ones of the fin-shaped transistor channel regions protruding from the first region are different than the respective widths of the ones of the fin-shaped transistor channel regions protruding from the second region.
