Abstract
Sidewall spacers formed on sides of mandrels are separated by first gaps in a first region and separated by wider second gaps in a second region. The second gaps are filled while a capping layer caps the first gaps. The capping layer is etched thereby exposing mandrels in the first region, which are removed. An underlying layer is patterned using the sidewall spacers separated by first gaps to form word lines in the first region and using sidewall spacers with filled second gaps to form select lines in the second region.
