FINFET CIRCUITS WITH VARIOUS FIN HEIGHTS

摘要

A fin field-effect transistor (finFET) assembly includes a first finFET device having fins of a first height and a second finFET device having fins of a second height. Each of the first and second finFET devices includes an epitaxial fill material covering source and drain regions of the first and second finFET devices. The epitaxial fill material of the first finFET device has a same height as the epitaxial fill material of the second finFET device.
