METHOD OF FABRICATING FIN-FIELD EFFECT TRANSISTORS (FINFETS) HAVING DIFFERENT FIN WIDTHS
摘要:
Provided are methods of forming field effect transistors. The method includes preparing a substrate with a first region and a second region, forming fin portions on the first and second regions, each of the fin portions protruding from the substrate and having a first width, forming a first mask pattern to expose the fin portions on the first region and cover the fin portions on the second region, and changing widths of the fin portions provided on the first region.
